Science and Technology Log

Without a vessel and without a crew, none of this mission would be possible. As I’ve said before, this crew is special. Like any job, employees are required, but that does not mean that you will work well cohesively and passionately towards a goal. The two weeks I’ve been spending with this crew who is so wholeheartedly excited about their job and role, while being on the ocean, has been so rewarding and inspiring. More later, this is starting to remind me of crying along with my sobbing fourth graders on the last day of school.

While I’ve discussed a lot of the daily operations of the crew and ship, and what I’ve been learning and working on myself, however, I have not discussed the vessel and agency that has made all of this possible. Many people question, “What is NOAA?” when I explain this opportunity.

About NOAA

NOAA logo: a circle bisected by the outline of a seagull, dark blue above the seagull's wings and lighter blue below. Around the circle read the words: National Oceanic and Atmospheric Administration, U.S. Department of Commerce.

“The National Oceanic and Atmospheric Administration (NOAA) is a U.S. government agency that was formed in 1970 as a combination of several different organizations. The purpose of NOAA is to study and report on the ocean, atmosphere, and coastal regions of Earth.”

National Geographic Education: “National Oceanic and Atmospheric Administration (NOAA)

“Our mission: To understand and predict changes in climate, weather, ocean, and coasts, to share that knowledge and information with others, and to conserve and managecoastal and marine ecosystems and resources.”

Namesake

“[Dr.] Bell M. Shimada (1922-1958), served with the United States Fish and Wildlife Service and the Inter-American Tropical Tuna Commission, and was known for his studies of tropical Pacific tuna stocks.”

Wikipedia: “NOAAS Bell M. Shimada

The ship’s namesake was known for his contributions to the study of Tropical Pacific tuna stocks, which were important to the development of West Coast commercial fisheries following World War II. Dr. Bell Shimada and colleagues at Pacific Oceanic Fisheries Investigations (POFI) Honolulu Laboratory were among the first to study the population dynamics of tunas and the oceanography affecting their abundance and distribution.

a man (Dr. Shimada) wearing a white t-shirt, shorts, and red baseball cap stands holding a penguin. He grasps the penguin securely beneath its wings, which are spread out to each side. The man, and the penguin, look at the camera. He appears to be on a vessel - we can see some ocean water in the background - and we can tell that two other people are behind him, mostly obscured.

Dr. Bell M. Shimada, circa 1957.
Wikipedia: “Bell M. Shimada

“In her remarks at the christening and launch, [Dr. Shimada’s daughter] Julie Shimada offered the following, “I hope the Bell M. Shimada is a lasting testament that no life is too short, no career too brief, no contribution too small, to make a difference.”

Personal Log

As this experience comes to the end, I reflect on all parts of this mission. The crew, vessel, marine life, food, sleep, friendships, and more. I’m so thankful I was able to have this experience and share NOAA’s Teacher at Sea program more with coworkers, family, friends, and my students. Meeting and talking with the crew resulted in long conversations and plenty of laughs and connections amongst each other that they previously had not known.

Winds and swells picked up over the weekend and on Sunday July 16 we only caught six Hake. After that trawl and an increase in marine mammals being sighted when we were trying to trawl, fishing was called off for the rest of the Leg. At 1020 Monday July 17, we completed our last transect for Leg 2 of the Survey and headed due North for the long trek to Newport, Oregon. We still found ways to entertain ourselves, nap, snack, share stories and riddles, take photos of sunsets and marine mammals, watch shooting stars and have a movie night. Below are photos of our art craft: fish prints of two Chilipepper Rockfish!

Did You Know?

NOAA Ship Bell M. Shimada has an endurance, the amount of time the vessel can be at sea in a row, of forty days. This is not because the ship can’t make its own fresh water through reverse osmosis from sea water, or a lack of fuel, oil, extra parts, or a way to exhume waste and trash in an environmentally friendly way…

but because of food!

Our galley crew is amazingly talented and spoils us with a huge all you can eat buffet, desserts, and drinks every day! But, as per various laws and for the safety of the crew, they are lawfully entitled to fresh fruit, vegetables, meat, etc. within set guidelines and window of time.

Animals Seen Today

Pacific White-Sided Dolphins! Although these energetic friends caused us to abandon a trawl attempt after multiple marine mammal watches ended early because of their presence, they were so much fun to watch! I brought my DSLR camera up to the bridge deck and eventually sat down on the deck watching them jump and race through the ocean waters next to the hull. Below are some of my favorite photos I took of the pod.

In my July 6 post, I explained how NOAA Ship Bell M. Shimada is equipped to collect acoustic data in the form of echo grams and therefore find fish to trawl for. In my July 10 post, I explained how we get the fish onboard, and what we do with the sample once it is collected from the net. These entries described what work is done in the Acoustics Lab and the Wet Lab, but there is one more Lab onboard to explore and explain: the Chemistry Lab.

Science and Technology Log

Each morning after breakfast, we usually gather in the Acoustics Lab, determine what transect we are on, if we are inshore or offshore, and in some ways: hurry up and wait. Once certain patterns and blips show up on the echo grams, the Acoustics team talks with the bridge and may request to turn around and attempt a trawl. After all marine mammal observations are completed, the net is retrieved, and the samples are brought to the Wet Lab, we sort and collect data on the samples. These operations usually take place between 0800 and 2000. (8am to 8pm)

So what happens at night? In the Chemistry Lab, scientists work with the Deck and Surveys Departments to deploy a collection of electronic instruments and 12 Niskin bottles (open bottles used to collect and hold water samples, about one meter long) secured to a cylindrical frame called a rosette. It is deployed from the side sampling station instead of the stern. Scientists onboard NOAA Ship Bell M. Shimada use the instruments and collection of water samples in two ways: measuring Conductivity, Temperature, and Depth (CTD) within a water column to study oceanography, and collecting environmental DNA (eDNA).

photo of a large piece of sampling equipment on deck. a large white metal cylindrical frame houses a ring of perhaps ten tall gray canisters - the Niskin bottles. The bottles circle the conductivity, temperature, and depth probe, which is barely visible. Behind the frame, past the ship's rail, we see vivid blue water with a few white caps and a coastal mountain range beyond.

CTD Niskin bottles arranged on a circular rosette frame.

“Nighttime operations primarily consists of deploying the Conductivity-Temperature [-Depth] (CTD) rosette which gathers oceanographic data such as conductivity, temperature, dissolved oxygen, and chlorophyll fluorescence. The CTD can also be triggered to collect water at specific depths.”

NOAA Fisheries: “eDNA Part 2: There’s a Lot of Water in the Sea – and the Chemistry Lab
NOAA Ocean Exploration: “What does “CTD” stand for?

Conductivity, Temperature and Depth: CTD

CTD stands for conductivity (ability to pass an electrical current), temperature, and depth. Scientists use the rosette frame, which is attached to the ship by cables, and has the CTD and 12 Niskin bottles attached, to collect electronic data and multiple water samples.

“A CTD device’s primary function is to detect how the conductivity and temperature of the water column changes relative to depth. Conductivity is a measure of how well a solution conducts electricity and it is directly related to salinity. By measuring the conductivity of seawater, the salinity can be derived from the temperature and pressure of the same water. The depth is then derived from the pressure measurement by calculating the density of water from the temperature and the salinity.”

NOAA Ocean Exploration: “What does “CTD” stand for?
Elysha, wearing an orange life vest and white NOAA logo hard hat, sits at a metal desk with two computer monitors and a keyboard. The monitors display data from the CTD. Elysha has her right hand on a computer mouse while her left grips a pen over a yellow legal pad. She is turning to smile at the camera.
Senior Survey Technician Elysha Agne gives commands to the Deck Department running the winch and cable to the rosette, and ensures quality data is being collected at each sampling depth.

“For more detailed analyses back in the lab, each of the large gray bottles captures a water sample at a different depth. The data provide scientists important information about the local aquatic environment.”

NOAA: “Photo story: Virtually cruise aboard a NOAA ship for a fish trawl survey

Depending on the depth at which the vessel is currently operating, the rosette will descend to one to five predetermined depths (50m-500m) for sampling. For example, if the vessel depth reads 400m, water samples will occur at 50m, 150m, 200m, and 300m (more information in Table 1 below). A water sample is also taken just below the ocean surface using a through hull fitting, which allows seawater to be collected via a hole in the hull that feeds directly to the Chem Lab.

Table 1. Sample depths for eDNA. Two independent samples should be taken at each depth. The total ocean depth of location for the CTD cast determines the depths at which water samples will be collected. The rows of the table are labeled Sampling Depth (m) and the columns are labeled Topography depth of CTD cast.
Table 1 in Protocol manual, written by Chem Lab member and eDNA scientist Abi Wells.

While the rosette descends, data is recorded from multiple sensors and are later used by scientists to compare with Acoustic and Wet Lab data and compile and categorize new information from the survey. Pressure, depth, temperature, conductivity, salinity, oxygen, fluorescence, and turbidity were all being recorded during this leg of the survey mission.

Program displaying data collected from the CTD rosette in real time.

Environmental DNA: eDNA

During the day, Hake stay in deeper waters, averaging around 200-350m, but at night the nocturnal feeders start their daily migration through the water column to shallower depths. They feed primarily on zooplankton, shrimp, myctophids (Lanternfish), and even young Hake at this depth. As Hake move throughout the water column, they leave behind DNA in the water that can be collected later as sort of a signature of their presence in that location. The collection, filtering, and preservation of sampled water in the ocean environment is categorized as collecting eDNA. This environmental DNA can be in the form of gametes (reproductive cells), fish scales, feces, etc.

Collecting water samples at different depths in the same vertical column can show what marine life was present at that location, and what depth they were at. I relate it to reviewing school security cameras or talking to other teachers at the end of the school day, to determine where a student was at a certain time and why.

The apparatus housing the CTD probe and Niskin rosette sits on deck. Abi, wearing a yellow hard hat, orange life vest, blue gloves and brown rubber boots, stands between the equipment and the rail of the ship to empty water from a Niskin bottle into a plastic bag. The profile of her face is mostly obscured by her long yellow ponytail.
Chem Lab member and eDNA scientist Abi Wells collecting a 2.5L water sample from a Niskin bottle after a successful CTD deployment.

When the rosette is back on deck, scientists use gloves and new collection bags called Whirlpacks, to collect approximately 2.5L of water from each 10L Niskin bottle. This process is conducted with a great emphasis on sterility, including wiping the bottle spigot with DNAway to remove any contaminants, using new materials, and not allowing fingers or the spigot to touch the collection bag.

Once the collection bags are filled and brought to the Chem Lab, filtration occurs using 1.0 micron filters. Although this size of filter, compared to smaller filters, allows some cells to pass through and not be collected, it is faster and results in less breakage of cells and loss of DNA. After 2.5L of the water sample is poured through individual filters for each depth sample, they are placed in pre-labeled (location and depth information) tubes with 2mL of preservative buffer. The tubes are stored at room temperature and away from UV light until NOAA Ship Bell M. Shimada is back in port and the samples can be further researched in on-land laboratories. Results from additional studies help to compile lists of marine life that was present in the water column and can be compared to acoustic data and species caught and logged in the Wet Lab.

Personal Log

So, there you have it. Three Labs onboard that conduct very different research, but fit together in the puzzle of Hake development, migration, diet, niches, ecosystem, biomass, and supporting sustainable commercial fisheries. Each additional piece of data; whether it be echo sounds, physical samples, eDNA, or CTD information, strengthens the others and helps to create a cohesive summary of the data. 

This was a lot to learn in the first few days, but as I’ve said before, all of the crew has been welcoming, supportive, and educational. Having a strong team that works together is priceless, and thoroughly noticed and appreciated. 

A few days into the mission my Mom asked me what the best part of my day was. I had three answers and haven’t had a day yet with only one answer. I replied that it was the great salmon dinner, clean clothes, and seeing Risso’s Dolphins for the first time.

Video taken by me of Risso’s Dolphins surfacing for air. (Plays on loop)

We are now a little more than halfway through the mission and it has truly flown by. We’ve shared riddles and daily Final Jeopardy questions. We’ve laughed over daily experiences and the faces Hake fish make. We’ve played music and watched baseball during dinner. We enjoy watching marine life and breathe in the salt air while strengthening our sea legs. Sometimes we just drink coffee and snack and enjoy this opportunity with each other, and that makes every part of the day the best part.

Did You Know?

Although Hake are occasionally cannibalistic, they are not at the top of their food chain. Humboldt Squid (Remember those 15 foot long tentacles in my Wet Lab post?), Dogfish Sharks, and marine mammals are all predators, as well as commercial fishing.
Today well over 100 Spiny Dogfish Sharks were inadvertently caught in the trawl, in the same location as the baskets of Hake we sampled from.
Maybe there were baby Hake fish in the sharks’ stomachs… we didn’t attempt to find out.

– – ⚓ – –

New Terms/Phrases

Although I had learned the terms a few days earlier, I got to help Wet Lab Lead Ethan Beyer collect otolith and stomach samples for the first time from a sub-sample of Hake the other day.

I watched and learned, then helped scan barcodes of otolith sample bottles, add 95% ethanol that is diluted 50/50 with water, and delicately pick up the ear bones with tweezers and place them in the bottle.

Additionally, each Hake in the sub-sample has its weight recorded, along with length, sex, and developmental stage. From that sub-sample, five stomachs are removed for later analysis, and five have their stomachs opened and their diet is recorded. We often find Lanternfish (Myctophids), Krill (Euphausiidae) and small Hake.

Me holding a Hake before sorting. After observation, we determined this was a developmentally mature female, measuring 50cm (20in) long!

In my July 6 blog post, I explained how NOAA Ship Bell M. Shimada is equipped to collect acoustic data in the form of echo grams. The acoustics team uses the data to determine if there are enough return signals to suggest fish are present and attempt a trawl. In this blog post, I will explain how we get the fish onboard, and what we do with the sample of marine life once it is collected from the net.

One question I had after learning about the acoustics and environmental DNA (eDNA) pieces of the survey mission was, “How does physically collecting and researching Hake samples fit into the puzzle of understanding their ecosystem and supporting sustainable fisheries?” (NOAA Fisheries quick facts and video here)

“While echosounders are useful, they do not provide certain quantitative data that researchers need to understand the ecology of these organisms and the midwater zone. To collect quantitative data, such as biomass, length and weight, and age class distributions, researchers must gather representational samples and take direct measurements of them. The best way to do this is by employing trawls.”

NOAA Ocean Exploration: “Trawls

So, although acoustics and eDNA research is important to the overall survey, they are only pieces of the puzzle, and the puzzle is not complete without conducting trawls and physically researching samples. NOAA Ship Bell M. Shimada uses a midwater trawl net that is deployed from the stern over the transom, and towed behind the vessel. As the name suggests, midwater trawls occur in the middle section of the water column, versus surface and bottom trawls. The net is conical in shape and uses two metal Fishbuster Trawl Doors, and two sets of heavy chain links called Tom weights, in order to keep the trawl in the middle of the water column.

The net in tow is conical, attached at four points to two bars that hold the opening apart, and these bars are attached to lines (ropes) extending back from the vessel. This net is capturing two fish and missing a third.
NOAA Fisheries: “Fishing Gear: Midwater Trawls

“The midwater region is especially important because the creatures that inhabit it constitute the majority of the world’s seafood. Understanding the ecology of midwater organisms and their vast environment can provide us with better information to manage these important natural resources and prevent their overexploitation.”

NOAA Ocean Exploration: “Trawls

Two deck crewmembers work with an orange and white fishing net on the aft deck of NOAA Ship Bell M. Shimada. They are wearing foul weather gear, life vests, and hard hats. At right, one leans over the net, searching for remaining captured fish. The other approaches from the left, looking down at the net, to assist. We can see a cloud-capped mountain range in the distance beyond the water.

Once the net is onboard, the net is emptied one of two ways depending on the size of the sample. For large samples, marine life is deposited into a hopper and subsequent conveyor belt. For smaller samples, the Hake will be put into a large basket then divided into smaller baskets of approximately 100 Hake each. Any other marine life like Salps, Myctophids, Pyrosomes, Rockfish, King of the Salmon, and small bony fish, etc. are recorded in the database and returned to the ocean.

“The ship’s wet lab allows scientists to sort, weigh, measure and examine fish. The data is entered directly into the ship’s scientific computer network.”

NOAA Office of Marine and Aviation Operations (OMAO): “Bell M. Shimada

Large basket containing a sample of Hake with a few (red) Splitnose Rockfish.

With our boots and bright orange rubber pants and gloves on, our first task is to distribute the sample of Hake into baskets of about 100 each. Based on how many baskets we fill, a random selection of baskets will be kept, and the others will be returned to the ocean. With the remaining groups of Hake, we determine their sex and length.

In order to do this, we use a scalpel to make an incision on the underside/belly of the Hake. Once open, we are able to examine their organs, including the gonads to determine if the fish is male or female, and if they are developmentally immature or mature. Young Hake are difficult to sex, and it takes practice to get over any initial fears of cutting into an animal; let alone being able to locate and identify the gonads. Hake usually spawn in early winter, so many of the smaller Hake we sample from during the summer are age one or younger.

Our largest Hake thus far was a developmentally mature female, measuring 50cm (20in). In order to accurately and consistently measure the length of the sample, we use a waterproof, magnetic plastic board with metric (centimeter and millimeter) markings called an Ichthystick (think: high-tech meter stick). The fish is placed on the board with its mouth touching the black board at 0cm, then a magnetic stylus is placed at the fork of the fish’s tail. Once the magnetic stylus is placed on the board, the length to the nearest millimeter is displayed on the LCD screen and automatically entered into the database program. The length data is grouped with the date, time, and identified sex for later observation and comparison.

Additional information, abstracts and outline about Ichthystick here

An even smaller subgroup is then selected and examined to record weights of individual Hake, collect ear bones called Otoliths for aging, stomach samples for diet, liver for RNA, and ovaries for maturity development. Otolith bones help determine the age of the Hake because they grow a new “layer” of bone each year, similar to coral structures and annual tree rings. Organs and bones removed from the Hake are sent to NOAA Fisheries centers for analysis and included in databases with the date, identified sex, length, weight, and location in which they were collected.

This data is used to build more of the puzzle, along with acoustical information, water samples, and eDNA data in order to further understand the ecosystem, biomass, diet, and

“support sustainable populations of Pacific hake on the West Coast.” (…)
“It provides vital data to help manage the migratory coastal stock of Pacific hake. The hake survey, officially called the Joint U.S.-Canada Integrated Ecosystem and Pacific Hake Acoustic Trawl Survey, occurs every odd-numbered year.”

Personal Log

Although this subtopic of explaining the Integrated Ecosystem and Pacific Hake Acoustic Trawl Survey is a bit easier to understand than my July 6 Acoustics Lab post, it certainly does not mean it’s an easy task!

When I had a tour on July 4, I remarked how clean and
organized the Wet Lab is. I hadn’t see it in action yet, but noticed how everything had its place and use. On July 6 we conducted our first trawl and collected a sample of 11 baskets of Hake (approximately 1,100 Hake since we group about 100 Hake together in each basket.) From that sample, we kept four baskets and counted, sexed, and measured 541 Hake.

Five of us were working together in the Wet Lab for that haul. I’ll admit I probably
didn’t sex 100+ Hake. It took a few minutes of watching the others carefully and swiftly cut into the underside of a fish, open the two sides, and know what to look for to determine the sex of very young Hake. Eventually I found the courage to slice in and take a look. By the fourth or fifth Hake, the uneasiness had subsided and I found the process very interesting and educational. Although young samples are hard to sex as they are often undeveloped, the others encouraged me and answered my questions and guesses with enthusiasm and support.

While working on measuring the lengths of our samples, one Science Team member paused and remarked how beautiful he found the fish. Although they do not have vibrant, bold colors, shimmering scales, or anything else particularly remarkable, he found the beauty in them. He digressed into a conversation of their role in the ecosystem, how they are living and breathing creatures, and how they probably all have their own personalities and slight physical differences. I noticed some of their eyes were shiny and sparkling, and how their faces and expressions were
noticeably unique the more you looked. That “down to earth”, heartfelt discussion was very special and demonstrated how the crew respects the process of catching and sampling Hake, while keeping each other and marine mammals safe.

From the NOAA Corps Officers, to the deck department, to the engineers,
electronics, science team, survey team, galley crew, volunteers, and everyone in between; the crew on NOAA Ship Bell M. Shimada is special. They take pride in their vessel and job, and always seem to have a smile and kind greeting. Being away from land and loved ones for weeks and months at a time will certainly take a toll on the body and mind, but this team is there for each other. To all of the crew, thank you for making me feel so welcomed and appreciated. We’re almost halfway through the mission, and as tired as I may get after (sometimes) 12+ hour days, I sleep well knowing the crew trusts their vessel and each other; and look forward to learning and becoming more and more acquainted each day with the people that make this mission possible. Thank you!

Did You Know? (FAQs)

1. Are you finding schools of them?

We’ve had seven successful trawls out of nine attempts for Pacific Hake fish. They often come with pyrosomes (Sea Pickle) myctophids (Lanternfish), and salps in the net too. Some trawl attempts are successful without a hitch, but more often than not we have to restart our Marine Mammal watches a few times before deploying in order to keep our ocean life safe and not get tangled in the net. Two trawl attempts have been abandoned because of the amount of persistent marine mammal life and playfulness near the ship. (I think they know we’re watching and show off for our cameras.)

2. What’s your average depth?

The transects (Set and numbered longitudinal east-west lines NOAA Ship Bell M. Shimada navigates on while collecting acoustic data) usually range from 50m – 1,500m (164ft – 4,921ft) in depth.

  • However, right now one of the displays in the Acoustics Lab, the depth reading is 3,240m which is about 10,630ft or just over two miles deep! 
  • This depth is only 1,870ft shallower than the wreck of the RMS Titanic! 
  • (We were on a long transect, we do not often see depths this great.)

3. Have you gotten seasick? Seasickness should subside after about 3 days.

I’ve never gotten seasick thankfully! Knock on wood and all the other premonitions, please.

4. What is the Hake role in the ecosystem?

More info on this coming in later posts after explaining our Chemistry lab and technology aboard! 

  • However, as predators, they can be cannibalistic towards their own kind. 
  • As far as their role in human consumption: They are often used as a substitute for Cod and Haddock, and in fish sticks and imitation crab meat.

Science and Technology Log

On July 6, our first full day at sea, we gathered in the acoustics lab to observe and keep watch on data from various screens. Data includes our current course plotted on a digital chart, a camera showing current sea state, measurements of the wind speed and direction, and displays of the multiple frequencies at which the Simrad EK80 transmitter emits sound. The EK80 is used while traveling on numbered longitudinal east-west lines called transects. NOAA Ship Bell M. Shimada navigates on these lines while collecting acoustic data along the west coast of the U.S. and into Canada, in hopes of finding schools of Hake to collect for surveying.

Black dots mark the locations of three coastal cities: Crescent City, near the top of the map; San Francisco, a little more than halfway down; and Morro Bay, toward the bottom of the map. Black horizontal lines mark transects extending west from the coast line. The black lines are marked with red or black x's (showing previous sampling locations, perhaps) and a couple have green triangles.

(We hope to survey transects 8-35 by Cape Mendocino, CA before traveling north to dock in Newport, OR.)

“For acoustic surveys, the ship uses a multibeam echo sounder (MBES) that projects a fan-shaped beam of sound that bounces back to the ship. The ship’s MBES—one of only three systems of its type worldwide—acquires data from both the water column and the sea floor.”

NOAA Office of Marine and Aviation Operations (OMAO): “Bell M. Shimada

The Simrad EK80 emits sound waves from the hull of the vessel down to the sea floor. The process is very similar to a dolphin or bat using echolocation to find prey. Any object the signal hits that has a different density and reflectivity than the surrounding water will cause the waves to bounce back to the ship. An image, called an echo gram, is pieced together each time this occurs and the acoustics team is able to use this information to determine if there are enough return signals that suggest fish are present to attempt a trawl.

Fish that have swim bladders, like bony fish, reflect or echo the sound wave back to the vessel very strongly. Other marine life such as myctophids and zooplankton also have a different density than the sea water, and reflect sound, although not as strongly as fish with air-filled swim bladders. The sea floor itself also reflects sound very strongly, because of the density difference between water and rocks, sand, and mud.

Marine life that have swim bladders (represented in blue) reflect or echo the sound wave back to the vessel. Examples of such marine life include bony fish, myctophids, and zooplankton, as well as the sea floor itself, which has a different density than the sea water.

If the acoustics team determines there is enough marine life (that they are interested in surveying) to attempt a haul, they will notify the bridge deck and officers that they would like to have the fishing net deployed.

Before an attempted haul, the science team conducts a marine mammal watch for ten minutes. In this time window, several pairs of eyes are observing from the bridge deck and stern for any signs of dolphins, whales, sea lions, seals, and any other marine mammals that are within 500 meters of the vessel. If any marine mammals are spotted within the ten minute observation, we will stand down and wait ten minutes before restarting the marine mammal watch. Net deployment cannot occur until the full observation window has completed.

First haul July 6:
1422-1432 Mammal watch, no marine mammals spotted.
The net deployment started, at which time the vessel continues forward at two knots. Vessel speed increases to three knots when the net is fully deployed with doors and weights in the water, which assist in opening the conical shaped net outwards linearly and laterally. During this time the science team watches displays of the EK80 frequencies and observe the linear width and depth of the net. Scientists can compare these displays to determine if the net is in the correct position to have the best chance of collecting fish.

Hauling back the net occurs after several minutes, at which time the vessel returns to a speed of two knots, and we estimate how many fish were collected. The amount of time in which the net is submerged depends on the depth of the water and acoustic information about the size of the school of fish the net is (hopefully) sampling. After recovery, the haul is deposited into a hopper which feeds onto a conveyor belt in the wet lab, then into large baskets and the wet lab team takes over.

During the first attempt, two sea lions were spotted which required the haul attempt to be paused. We restarted the ten minute marine mammal watch from 1500-1510, the deck department retrieved and reset the net, and the vessel was turned around to return to the start of the noted longitudinal transect. With no marine mammals spotted during the observation period, the second attempt was successful and resulted in:

– 1604-1634: 30 minute haul at 350m depth.

– 11 baskets of Hake collected.

– 4 sample baskets kept at random.

– 541 Hake counted and studied in the wet lab.

Personal Log

On July 4 I arrived to pier 30/32 in San Francisco, CA to board NOAA Ship Bell M. Shimada. Although I grew up volunteering on the 441’ WWII Liberty Ship SS John W. Brown in Baltimore, MD, seeing a new ship still resulted in a mix of emotions, nervousness, adrenaline, excitement, and everything in between. After five and a half years, finally seeing the 208’ vessel that would become my home for the next two weeks was a core memory and feeling I will always remember.

Once onboard, I met Chief Scientist Steve de Blois and Wet Lab Lead Ethan Beyer. I was given a tour of the acoustic, chem, and wet labs and shown to my cabin. After dinner ashore, I joined some of the crew on the flying bridge to watch the July 4th fireworks. I met additional science team members and enjoyed a long night’s rest.

In the morning on July 5, we had a welcome aboard meeting, various trainings, a safety meeting and orientation, fire and abandon ship drills, and a science team meeting. We introduced ourselves, took an official team photo, and soon departed pier 30/32 for our 14 day mission. After passing under the Golden Gate Bridge and heading to the Pacific Ocean, our cold hands were warmed by a wonderful hot dinner of chicken, steak, fresh veggies, salad, and desserts from our galley crew. After dinner, we settled in for our first night at sea, waiting with anticipation for our first trawl on July 6.

Introduction and Background

Hello! My name is Lisa Carlson and I am an elementary school teacher in Virginia Beach, Virginia. I have taught third, fourth, and fifth grade general education with Special Education and English as a Second Language (ESL) inclusion. This coming fall I will be a second grade teacher, continuing with ESL inclusion! Although I was surprised to move down from fourth grade, I try to maintain the belief that everything happens for a reason, and the only constant in life is change.

For example, if I not missed out on previous opportunities to join NOAA as a Teacher at Sea due to the pandemic, a short career change, and other extenuating circumstances; I wouldn’t be writing this blog from a hotel room in San Francisco, California, anticipating boarding and seeing July 4th fireworks from the deck tomorrow.

My introduction to NOAA’s Teacher at Sea program began in the fall of 2017. After student teaching in the fall/winter of 2016 in a third grade class, and permanent subbing in a fifth grade in the winter/spring of 2017, I accepted a position for my own third grade classroom.

My classroom came together with a nautical theme, shades of blues and calm colors, nautical paintings by my Mom, lots of cleaning and moving by my Dad, sailboat name tags on the door, and our own 3D sailboat in my class library. It soon got around that my room was one to go see!

A closed classroom door papered in shiny blue-green wrap on the top half (representing ocean) and brown on the bottom half (representing sand). Paper sailboats of different colors are taped onto the "ocean;" each has a student's name (not legible). Four yellow flip flops, with more labels, are taped to the "sand." At the top of the door, blue letters on a black paper background say: WELCOME ABOARD.

Our Technology Integration Specialist, a NOAA Teacher at Sea Alumnus, visited my room and explained the program to me. The application was due on my birthday, less than a month from when I learned about the opportunity.

– – ⚓ – –

So, I applied in November 2017, 2018, and 2019. One year I just wasn’t selected, one year administrative input was not turned in on time, and other hiccups along the way. Then, my 2019 application was accepted, and I was over the moon in January 2020 to learn that I was a finalist. Of course, we all know what happened that March; and the 2020 and subsequent 2021 sailing seasons were canceled. Slowly, a few teachers were able to sail in the summer of 2022, and I was able to read their blogs from afar with the belief of everything happening for a reason.

My 2023 NOAA Teacher at Sea Assignment!

Now, it’s my turn! I will be sailing off the coast of California for two weeks on NOAA Ship Bell M. Shimada with members of the science team as part of the Integrated Ecosystem and Pacific Hake Acoustic Trawl Survey.

“For three decades, the Teacher at Sea program has helped teachers participate in annual NOAA research surveys conducted by our scientists. Teachers from around the country embark on a two to three week expedition at sea. They gain invaluable on-the-job experience and communicate their journey through a series of blogs and lesson plans.”

NOAA Teacher at Sea Blog: “Looking Back on 30 Years of Teachers at Sea

I am so excited for this opportunity and experience after five and a half years of anticipation. So follow along, wish us fair winds and following seas, and as many schools of Pacific Hake as possible to sample from and research!

On July 23, we briefly suspended our operations to help out fellow scientists camped out on the French Frigate Shoals (Lalo), located along the Northwest Hawaiian Island chain – about halfway between the northernmost main islands and Midway (Kuaihelani).  The trip was brief, and we never set foot on terra firma, but with the help of the Big Eyes we could see something that we had not seen up close in 3 days – land.

Two nights prior, we finally crossed over to the Northwest Hawaiian Islands – a sacred and certainly mysterious (at least to me)  area for the Hawaiian People.  I was waiting with some anticipation for the moment we would cross into these waters.  The entire Northwest Hawaiian Island chain and its surrounding seas are limited-access for the vast majority of seafarers; the waters are protected by a proclamation signed by President George W. Bush in 2006, and expanded by President Barack Obama in 2016. This Marine Sanctuary’s designated area begins near the start of the Northwest Hawaiian Island chain, and stretches all the way to the Kure Atoll (Hōlanikū), just past Midway Island (Kuaihelani).  We were not permitted to cross into these waters until we had a permit, part of which included a component requirement of a briefing on the history of the area before we entered.  ers Native Hawaiian Program Specialist Kalani Quiocho introduced us to this sacred ground during our pre-cruise training with this briefing on this Marine National Monument, Papahānaumokuākea.  His presentation was so moving that I felt it necessary that the story of these waters (through my limited experience) must be told.

Mr. Quiocho’s presentation began with the name song for Papahānaumokuākea.  His voice bellowed out in an ethereal chant – one in a smooth and haunting language with sound combinations like nothing I had ever heard before.  His song was punctuated with ‘okinas and kahakōs, and accented with stunning photographs of ocean life, ritual, and artifact.  The music moved me to a tear, though I couldn’t quite pinpoint the emotion that was supposed to accompany it.

name song for papahanamoukuakea
The Name song for Papahānaumokuākea, reprinted with permission from Kalani Quiocho.

I realize now that I have traveled to this sacred place that it was one of simple reverence for the culture and its people who belong so fully to it.  It was at that moment that I realized that this trip would be a whole other ball game – one that is sacred, cosmic, and mysterious.

Papahānaumokuākea (pronounced Papa-hah-now-mow-coo-ah-kay-a) is the first officially designated Mixed Cultural and Heritage site, and is the largest fully protected conservation area in the United States.   Its name commemorates the union of two Hawaiian ancestors – Papahānaumoku and Wākea, who according to Hawaiian ancestry gave rise to the Hawaiian archipelago, the taro plant and the Hawaiian people.  These two ancestors provide a part of the Genesis story for Hawaiʻi – land to live on, food to eat, and people to cultivate, commune, and thrive as one with the gifts of their ancestors. The namesake alone of this marine sanctuary highlights the importance of its existence and its need for protection.  Many of the islands are ancient ceremonial sites, two of which we passed on the way to the Shoals (Lalo).

Crossing over to the Northwest Hawaiian Islands also marks a celestially significant line in the Hawaiian archipelago – the Tropic of Cancer.  The Tropic of Cancer is the furthest north that the sun will reach a direct overhead path during the solar year – you might know this as the summer solstice.  Right on the Tropic of Cancer lies the island Mokumanamana, a sacred place of cultural distinction for the Hawaiian people.  The Tropic of Cancer divides the entire Hawaiian archipelago into two distinct sections, Pō and Ao – the Ao represents the more southern islands and spiritual daylight, and the Pō representing the Northwest Hawaiian Islands and spiritual twilight.

ao and po
This diagram shows the separation between the NWHI and the main Hawaiian Islands. The horizontal line through the center divides day (Ao) from night (Pō) and lines up with the Tropic of Cancer. The Island Mokumanamana lies directly on the boundary between the living and spiritual realms. Our destination was Lalo, or French Frigate Shoals, though our travels took us much further northwest than that. (Diagram Credit: Kalani Quiocho)

The crossing over as we passed Mokumanamana is significant in that we entered a different spiritual zone of the Hawaiian Islands.   The Papahānaumokuākea Marine National Monument’s website (click here to read much more about it) describes the Northwest Hawaiian Islands as “a region of primordial darkness from which life springs and spirits return after death.”  In this sense, transiting past Mokumanamana represented a “crossing over” into a different realm of ancient history.  Mokumanamana is known for its high density of ancient ceremonial sites and is considered a center of Hawaiian religion and ideology.  Mr. Quiocho expands on the geographical importance of the area to the Hawaiian people in his commentary stating that,

“Papahānaumokuākea encompasses the Northwestern Hawaiian Islands which is ¾ of the Hawaiian archipelago and includes high basalt islands and low-lying atolls, and surrounding marine environments. It stretches nearly 2,000 kilometers and straddles the Tropic of Cancer also known to Hawaiʻi as Ke Ala Polohiwa a Kāne – The sacred black glistening path of Kāne, the patron god of the sun. It is believed that the Hawaiian Archipelago is divided into two regions called Pō and Ao, which essentially means night and day. Most of the NWHI is within Pō, a place of creation and origin where ancestors return to after death. The region known as Ao includes the main Hawaiian Islands where man resides. The entire Hawaiian Archipelago represents the dualisms and cycles of the Hawaiian universe. From the east where the sun rises and the islands are volcanically birthed from the oceanic womb to the west where the sun sets and the islands return to the sea. And all of the extraordinary biology that is found in the Northwestern and main Hawaiian Islands are accounted for in our oral traditions. The Kumulipo, a creation chant with more than 2,000 lines expresses the cosmology of the Hawaiian Islands, beginning with the birthing of the coral polyp and eventually the Hawaiian people. Naturally this is an inspiring place that is the framework of our worldview and the knowledge systems that tell us we are people of place. Which is why many refer to this area as the kūpuna islands, kūpuna meaning elder or grandparent.”

Today, Native Hawaiians will travel by double-hulled canoes from the main islands all the way up to Nihoa and Mokumanamana during times of ritual importance and follow in the footsteps of their ancestors to honor the tradition and the spiritual practice.  I’m sure the journey is both treacherous and fulfilling, one that would rival other more commonly known great expeditions, especially considering its spiritual significance.

Papahānaumokuākea is rich with history – both ancient and recent, and full of its own surprises!

Mr. Quiocho continues by expanding on the importance of the navigation of these waters to the Hawaiian people and how it honors their homeland connections:

“Native Hawaiians believe that the vast region that makes up the NWHI is an incredibly sacred place and is regarded as the construct of their cosmological genealogy. This region is rooted in creation and origin as a place where all life began and to which ancestors return after death. Native Hawaiians have historical connections to all parts of their homeland, which encompass all the islands, atolls, shoals, coral reefs, submerged seamounts and ocean waters that connect them. While the islands themselves are focal destinations for traditional voyages, the vast ocean is equally important. It is a cultural seascape that is imbued with immense value. The ocean is more than an unknown empty space that isolates islands, but rather a pathway for movement and potential.

A rare sighting of Tropical Pacific Orca – one of the first Cetaceans to welcome us to the Monument. What a gift!

Long-distance voyaging and wayfinding is one of the most unique and valuable traditional practices that Native Hawaiians have developed and continue to advance. It is an ancient way of interacting with the ocean that continues to inspire and create social change. The ocean region surrounding the NWHI is the only cultural voyaging seascape within the Hawaiian Archipelago. The main Hawaiian Islands are large enough for any novice navigator to find, but the ocean region throughout and surrounding Papahānaumokuākea provides challenging opportunities for apprentice navigators to excel. This expansive ocean environment was the setting for ancient Hawaiian chiefs to voyage back and forth between the main Hawaiian Islands and the NWHI over the course of 400 years.”

On our journey, we slipped passed Mokumanamana in the cover of night – through the invisible gates and into this ancient ancestral realm.  Although we had been in the monument since the previous day, for some reason this crossing marked a distinction for me personally in an indescribable way.  Since arriving on Oahu and in my travels since, I’ve known there was something special and different about this place, and I’ve known that part of the “different” was me.  Walking through Ala Moana Park on the 4th of July revealed threads of a culture that formed a beautiful tapestry of family, community, and heritage as I strolled past hundreds of families camped out in anticipation of the upcoming fireworks over the ocean.

A volcanic neck stands high above the waters surrounding the shoals.

There was something communal and sacred about it, even though the time and event was modern.  There was an “old” feeling of togetherness that buzzed through the park amongst strangers and friends.  I knew I was an outsider to this energy, but I didn’t feel entirely left out of it.  It’s one thing to feel like a foreigner on the “day” side of the Tropic of Cancer, but the “night” side held a spiritual distinction, as though I was trespassing in a dimension to which I did not belong. Knowing that the only passage of ships through this area would come with permits and regulations left a feeling of emptiness in an already vast ocean.  Knowing the ocean is full beneath with life both current and past – fish and whale and ancient Hawaiian spirit alike gave back some reassurance that we were not entirely alone.  For the first time I didn’t want to just know about Papahānaumokuākea, I wanted the ocean to tell me the story herself.

Nestled in the middle of Papahānaumokuākea was our target destination – French Frigate Shoals (Lalo).  On this tiny island a small team of scientists have been camped out for a little over six weeks studying the endangered Hawaiian Monk Seal.  We were tasked with delivering critical supplies to the scientific team – fuel, replacements of scientific gear, and a small care package with a few creature comforts they had not had access to in quite some time.  (I mean, seriously.  Who drops off fuel without dropping off chocolate? Not us!)   We also picked up some specimens from them to take back to the lab in Honolulu. The Shoals are a special place – a World War II military outpost slowly decays on the far side of the island, providing some cover for the scientists as they work. The island hosts thousands upon thousands of terns, flying en masse around the island in huge swarms.

FFS
A closer view of the island. The dots in the air above the island are all birds.

The terns were in preparation of fledging, and in anticipation of that day, tiger sharks stalked the surrounding waters, waiting for their next meal. On the opposite side of the island a few hundred meters away from shore, a lone sandbar (formerly dredged up for use as a military runway) rose to the surface providing a quiet place for a monk seal and her two pups to lounge in the sand.  One seal pup practiced swimming in the shallows as the mother casually glanced in its direction.  The other pup would hobble a few feet away down the beach, only to run back to its mother and lie next to her for a time.  It was a little reminiscent of a Norman Rockwell beach vacation painting, had Rockwell chosen an animal personification route as his medium.  A turtle dotted the far edge of the landscape on the main island, basking in the rising sun as the waves gently rolled on to the beach behind him.

runway
This flat strip of land is a dredged up runway, slowly returning back to the ocean after years of abandonment from use. A mother seal and two pups lounge on the sand, enjoying the sun.

The structures on the land from afar looked like a distant movie set for an apocalyptic storyline. The wind howled as we approached the atoll, and birds fought against the invisible currents in frantic circles around the island.  Two boats lay destitute along the far side of the island while waves crashed merciless against the sea wall built to hold the atoll in place during the time the island was volunteered to serve in a wartime capacity. The island itself is a surreal duplicity – serving both as a protector of life and a vessel of war.  I found myself taking stock of this history;  watching from far away to learn the eternal evolution of this strange place – first a volcano, sunk beneath the surface, then to a primordial breeding ground for coral, fish, and shark – onto a pristine landscape, possibly used by ancestral Hawaiians for ceremony and stopover en route to Kure (Hōlanikū) – a military base as a refueling station and an outpost – and finally a protected home for hundreds of species, some hanging desperately onto the last strings of life but finally thriving under the care of a dedicated research team.

As much as I desperately wanted to go on to the island to have a look at this former military operations base-turned-endangered-animal-sanctuary, none of us could go on shore – even those who shuttled supplies to the scientists.  French Frigate Shoals marked the first time I had ever seen a coral atoll in anything other than a picture, and it seemed a natural part of my inner explorer to want to pop on to shore to have a look about, even for just a few minutes.  Everything in French Frigate Shoals is protected under the Papahānaumokuākea permitting restrictions.

pulley system
Supplies were hauled ashore by the small pulley system jutting up from the shoreline – visible on the left-middle portion of the island.

Had we wanted to explore the land, we would have needed to quarantine our clothing and ourselves for a minimum of 72 hours to protect the landscape from anything foreign taking foot on shore. Our ship couldn’t make it much closer than a mile or two from the island so as not to put it in danger of running aground. So, a team of four people shuttled supplies in the small boat, navigating the shallows and hauling the supplies on shore through a pulley system.  Two quick trips out to the island, and we were soon on our way again in our search for cetaceans.

When Mr. Quiocho parted ways with us after our training, he made a casual but powerful statement in closing.  He told us the whale dives deeply to commune with ancient wisdom commissioned to the deep ocean, bringing this deep knowledge from the ancestral depths to the surface so that it can become part our collective consciousness. Our trip, then, is a not merely a collection of data or a series of samples.  Each time we interact with the whales, they are bringing us the knowledge of the ancients in hope that we will continue to pass that information on to anyone at the surface willing to listen. The responsibility of our work when described in this light brought a new reverence to the study – one that is not just a story for the present in hopes of preserving for the future, but that weaves ancient knowledge from the past into our work, as well.

  •         Ship safety is the height of the focus of everyone on board.  Each Friday, we complete drills to make sure we are ready in the event of an emergency.  Of the many dangers at sea, a fire can prove to be most catastrophic.  It’s not like the fire department can come out to the middle of the Pacific at the first sign of burning bacon (which may or may not have happened to me two days before I left for Oahu).  The entire Sette crew acts as the fire department, so it is important for them to practice in the event of an emergency.  This week we simulated a live-fire scenario, complete with a fog machine.  I got to call the drill up to the bridge!  It was a little extra fun built into a very serious situation.

Personal Log
In 2011 I was honored to learn and work aboard the NOAA ship the Oscar Dyson in Alaska as a Teacher at Sea, and I can’t tell you how many people told me that it was the trip of a lifetime.  Imagine my excitement to learn that I get to return to sea as a Teacher at Sea alumni aboard the Bell M. Shimada.  The way I see it is that I get two trips of a lifetime, in one lifetime!  I feel pretty lucky.

On my first Teacher at Sea voyage, I documented my trip via a cartoon series called Adventures in a Blue World, a tribute to Sylvia Earle’s book The World is Blue.  This time I will once again do my best to bring to life my Teacher at Sea experiences via a second volume of cartoons.  You can read the introduction below on being selected as a Teacher at Sea, Hake, and the beginning of this next adventure.  (Cartoon citations 1, 2, and 3)

I have been an educator for nineteen years, and now live and work in West Texas–on the Llano Estacado–in Lubbock.  I’m a science instructional coach at Estacado High School, which basically means that I get to collaborate with teachers and students to develop great labs and activities.  It is a wonderful job, and I am looking forward to bringing back real-world research and developing curriculum for our students.

I am going to miss my family, Ike, Madalyn, and Eva.  The girls love the water (even bringing inflatable fish into the house…), and Ike has run rivers all over the Southwest, but I get to go where no family and friends are allowed–from Newport, Oregon, to Seattle, Washington on the NOAA ship the Bell M. Shimada.  They will also be following along with me remotely.

When an anchor is dropped, forces in the ocean will cause this massive object to drift as it falls.  Last year, after the anchor of mooring 12 was dropped, an acoustic message was sent to the release mechanism on the anchor to locate it.  This was repeated in three locations so that the location of the anchor could be triangulated much like how an earthquake epicenter is found.  This was repeated this year for mooring 13 so next year, they will know where it is.  From where we dropped the anchor to where it fell, was a horizontal distance of 3oo meters.  The ocean moved the 9300 pound anchor 300 meters.  What a force!

The next morning as the ship was in position, another acoustic message was sent that triggered the release of the glass floats from the anchor. Not surprisingly, the floats took nearly an hour to travel up the nearly 3 miles to the surface.

Float recovery
A small boat went to retrieve the mooring attached to the floats

Once the floats were located at the surface, a small boat was deployed to secure the end of the mooring to the Hi’ialakai. The glass floats were loaded onto the ship.  17 floats that had imploded when they were deployed last year.  Listen to imploding floats recorded by the hydrophone.  Implosion.

Next, came the lengthy retrieval of the line (3000+ meters). A capstan to apply force to the line was used as the research associates and team arranged the line in the shipping boxes. The colmega and nylon retrieval lasted about 3 hours.

Once the wire portion of the mooring was reached, sensors were removed as they rose and stored. Finally the mooring was released, leaving the buoy with about 40 meters of line with sensors attached and hanging below.

The NOAA officer on the bridge maneuvered the ship close enough to the buoy so that it could be secured to the ship and eventually lifted by the crane and placed on deck. This was followed by the retrieval of the last sensors.

Mooring removal was accomplished in seas with 5-6 feet swells at times. From my vantage point, everything seemed to go well in the recovery process. This is not always the case. Imagine what would happen, if the buoy separated from the rest of the mooring before releasing the floats and the mooring is laying on the sea floor? What would happen if the float release was not triggered and you have a mooring attached to the 8000+ pound anchor?  There are plans for when these events occur.  In both cases, a cable with a hook (or many hooks) is snaked down to try and grab the mooring line and bring it to the surface.

Now that the mooring has been recovered, the science team continues to collect data from the CTD (conductivity/temperature/depth) casts.  By the end of tomorrow, the CTDs would have collected data for approximately 25 hours.  The data from the CTDs will enable the alignment of the two moorings.

The WHOTS (Woods Hole Oceanographic Institution Hawaii Ocean Time Series Site) mooring project is led by is led by two scientists from Woods Hole Oceanographic Institution;  Al Plueddeman and Robert Weller.  Both scientists have been involved with the project since 2004.  Plueddeman led this year’s operations and next year it will be Weller.  Plueddeman recorded detailed notes of the operation that helped me fill in some blanks in my notes.  He answered my questions.  I am thankful to have been included in this project and am grateful for this experience and excited to share with my students back in Eugene, Oregon.

The long term observations (air-sea fluxes) collected by the moorings at Station Aloha will be used to better understand climate variability.  WHOTS is funded by NOAA and NSF and is a joint venture with University of Hawaii.  I will definitely be including real time and archived data from WHOTS in Environmental Science.

Personal Log

I have really enjoyed having the opportunity to talk with the crew of the Hi’ialakai.  There were many pathways taken to get to this point of being aboard this ship.  I learned about schools and programs that I had never even heard about.  My students will learn from this adventure of mine, that there are programs that can lead them to successful oceanic careers.

Brian Kibler
Brian Kibler

I sailed with Brian Kibler in 2013 aboard the Oscar Dyson up in the Gulf of Alaska.  He completed a two year program at Seattle Maritime Academy where he became credentialed to be an Able Bodied Seaman.  After a year as an intern aboard the Oscar Dyson, he was hired.  A few years ago he transferred to the Hi’ialakai and has now been with NOAA for 5 years.  On board, he is responsible for rigging, watch and other tasks that arise.  Brian was one of the stars of the video I made called Sharks on Deck. Watch it here.

Tyler Matta
Tyler Matta, 3rd Engineer

Tyler Matta has been sailing with NOAA for nearly a year.  He sought a hands-on engineering program and enrolled at Cal Maritime (Forbes ranked the school high due to the 95% job placement) and earned a degree in maritime engineering and was licensed as an engineer.  After sailing to the South Pacific on a 500 ft ship, he was hooked.  He was hired by NOAA at a job fair as a 3rd engineer and soon will have enough sea days to move to 2nd engineer.

 

 

There are 6 NOAA Corps members on  the Hi’ialakai.  They all went through an approximately 5 month training program at the Coast Guard Academy in New London, CT.  To apply, a candidate should have a 4 year degree in a NOAA related field such as science, math or engineering.  Our commanding officer, Liz Kretovic, attended Massachusetts Maritime Academy and majored in marine safety and environmental protection.  Other officers graduated with degrees in marine science, marine biology, and environmental studies.

ENS Chappelle
NOAA Ensign Nicki Chappelle

Ensign (ENS) Nikki Chappelle is new to the NOAA Corps.  In fact, this is her first cruise aboard the Hi’ialakai and second with NOAA.  She is shadowing ENS Bryan Stephan for on the job training.  She spent most of her schooling just south of where I teach.  I am hoping that when she visits her family in Cottage Grove, Oregon that she might make a stop at my school to talk to my students.  She graduated from Oregon State University with degrees in zoology and communication.  In the past she was a wildfire fighter, a circus worker (caring for the elephants) and a diver at Sea World.

All of the officers have 2 four hour shifts a day on the bridge.  For example ENS Chappelle’s shifts are 8am to 12pm and 8pm to 12am.  The responsibilities of the officers include navigating the ship, recording meteorological information, overseeing safety.  Officers have other tasks to complete when not on the bridge such as correcting navigational maps or safety and damage control. ENS Stephan manages the store on board as a collateral assignment.  After officers finish training they are sent to sea for 2-3 years (usually 2) and then rotate to land for 3 years and then back to sea.  NOAA Officers see the world while at sea as they support ocean and atmospheric science research.

Frank Russo
ET Frank Russo

Electronics technician (ET) seem to be in short supply with NOAA.  There are lots of job opportunities.  According to Larry Wooten (from Newport’s Marine Operation Center of the Pacific), NOAA has hired 7 ETs since November.  Frank Russo III is sailing with NOAA for the first time as an ET.  But this is definitely not his first time at sea.  He spent 24 years in the navy, 10 at Military Sealift Command supporting naval assets and marines around the world.  His responsibilities on the Hi’ialakai include maintaining navigational equipment on the bridge, making sure the radio, radar and NAVTEX (for weather alerts) are functioning properly and maintaining the server so that the scientists have computer access.

I have met so many interesting people on the Hi’ialakai.  I appreciate everyone who took the time to chat with me about their careers or anything else.  I wish I had more time so that I could get to know more of the Hi’ialakai crew.  Thanks.  Special thanks to our XO Amanda Goeller and Senior Scientist Al Plueddeman for reviewing my blog posts.  And for letting me tag along.

 

Did You Know?

The buoy at the top of the mooring becomes a popular hang out for organisms in the area. As we approached mooring 12, there were several red-footed boobies standing their ground. There were also plenty of barnacles and other organisms that are planktonic in some stage of their lives. Fishing line is strung across the center of the buoy to discourage visitors but some still use the buoy as a rest stop. The accumulation of organism that can lead to corrosion and malfunction of the equipment is biofoul.

Denise Harrington, Getting Ready for an Adventure, April 23, 2016

NOAA Teacher at Sea
Denise Harrington
(Almost) aboard NOAA Ship Pisces
May 04, 2016 – May 17, 2016

Greetings from Garibaldi, Oregon. My name is Denise Harrington and I teach Second Grade at South Prairie Elementary School in Tillamook, Oregon, along the north Oregon coast. There are 300 amazing second and third graders at our school who can prove to you that no matter how young you are, you can be a great scientist.  Last year they were caught on camera by Oregon Field Guide studying the diversity of life present in our ocean.

 

I applied to become a NOAA Teacher at Sea because I wanted to work with scientists in the field. I seem to learn best by doing.  In 2014, I joined the crew of NOAA ship Rainier, mapping the ocean floor near Kodiak Island, Alaska.  I learned how vast, connected, and undiscovered our oceans are. Students watched in disbelief after we discovered a sea floor canyon.  I learned about the technology and skills used to map the ocean floor. I learned how NOAA helps us stay safe by making accurate nautical charts.  It was, for our students and myself, a life changing experience.

As an avid sea kayaker, I was able to share my deeper understanding of the ocean with fellow paddlers. Photo courtesy of Bill Vonnegut

Now, I am fortunate enough to participate in another NOAA survey. On this survey aboard NOAA ship Pisces, scientists will be collecting data about how many fish inhabit the area along banks and ledges of the Continental Shelf of the Gulf of Mexico.
NOAA believes in the value of sharing what they do with the public, and students in particular. The crew of Pisces even let fifth grader students from Southaven, Mississippi name the ship after they won a writing contest. Maybe you can name the next NOAA ship!

On May 3, 2016, Ship Pisces will begin Leg 3 of their survey of reef fish. I have so many questions.  I asked Chief Scientist Kevin Rademacher why the many survey partners chose snapper and grouper to survey. He replied “Snapper and grouper are some of the most important commercial fisheries here in the Gulf of Mexico. There are 14 species of snapper in the Gulf of Mexico that are good to eat. Of those the most commercially important is the red snapper. It is also currently over-fished.”   When I hear “over-fished” I wonder if our second graders will have many or any red snapper to eat when they they grow up. Yikes!

Another important commercial catch is grouper.  My brother, Greg, who fishes along the Kenai River in Alaska understands why grouper is a focus of the survey. “It’s tasty,” he says. I can’t believe he finds grouper tastier than salmon.  NOAA is making sure that we know what fish we have and make sure we save some for later, so that everyone can decide which fish is the tastiest when they grow up.

I have so many questions keeping me up at night as I prepare for my adventure. What do I need to know about fish to do my job on the ship?  Will I see evidence of the largest oil spill in U.S. history, the Deepwater Horizon spill? How crowded will we all be aboard Ship Pisces? If I dissect fish, will it be gross? Will it stink?  Will I get sea sick? With my head spinning with questions, I know I am learning. Yet there is nothing more I can do now to prepare myself for all that I will learn, except to be early to the airport in Portland, Oregon, and to the ship in Pascagoula, Mississippi, on May 3rd.

I will get home in time to watch my daughter, Elizabeth, graduate from high school.  Ever since I returned from the NOAA cruise in Alaska, she has been studying marine biology and even competed in the National Ocean Sciences Bowl.

During research in the Gulf of Mexico with the crew of Ship Pisces, I will learn about the many living things in the Gulf of Mexico and about the technology they use to protect and manage commercial fisheries.  Soon, you will be able to watch me collect data about our ocean critters. Hope for fair winds and following seas as I join the crew on Ship Pisces, “working to protect, restore, and manage the use of our living ocean resources.”

Aboard NOAA Ship Rainier
September 8 – 24 , 2015

Date: September 9, 2015

Current Location: Women’s Harbor, U.S. Coast Guard Base, Kodiak, Alaska

Science Log

Kodiak, Alaska is amazing and NOAA Ship Rainier is even more so.  When I arrived I learned that we were going to be in port for a few days.  Instead of leaving on Tuesday, September 08, 2015 we are scheduled to leave on Saturday.  Early in my planning and training I learned that FLEXIBILITY is very important and it has proven to be true.

NOAA TAS 2015 005
Rainier with the rising sun behind it at Women’s Bay

During this time at port, the entire crew is very busy with ship activities.  I thought this would be the perfect time to give some background on this amazing ship!  Here is a link to more detailed information Rainier information flyer.  An even more detailed, “let the geek out” link is   Rainier special details.

Rainier is named after Mount Rainier in Washington State and was put to work in 1968.  Do the math, how old is Rainier this year?  Rainier is a long 231 foot ship.  The breadth (width) is 42 feet and the draft, or how far down it sits in the water is 14 feet.  One of the most interesting facts about this vessel is the ice strengthened hull.  Rainier is one tough ship!!

To keep this unique ship running so well it has an incredible crew.  I have learned that there are 7 main areas of work.  I am only going to give a general overview so everyone can understand a little bit more about what happens here.  I will go into more detail with future blogs.

Wardroom – This is what the NOAA uniformed officers are called.  They can be seen wearing their blue uniforms.  The hydrographic officers have a more interesting job than the officers on other NOAA vessels because they act not only as officers getting the ship where it needs to go safely, but they also work right alongside the survey scientists making tidal observations and coastal maps.

The Rainier Officers working in the Plotting Room

It makes a lot of sense for the people who are researching and creating the very important coastal maps to understand them.  There is no one better than the men and women who work with them every day!

Survey – These are the scientists who work with the officers to collect the data.  Collecting the data is just the beginning.  Once the data is collected they begin analyzing data and putting it to work.  Similar to students who have classwork, they get assignments that need to be met and deadlines to get the work done.  It can take weeks and months for the data to be put together to make the charts.

Engineering – The engineers are the inner working of the ship.  They are the men and women who keep Rainier going strong!  While here, there is a constant hum of mechanical parts (later the engines will be going and we will hear and feel those).

Just one of many areas the engineers work. This is an organized machine shop for repairs/fabricating.

Everywhere you look inside the ship you can see something that the engineers are responsible for maintaining.  On my tour, I was amazed from top to bottom of the fans, gears, plumbing, wires, generators, motors, hydraulics, engines, heating/cooling, launch maintenance, refrigeration, distillers for water plus so much more that needs to be kept going.  As you can see, this is also a very busy department!

Deck – While the engineers maintain the inside of the ship, the deck crew maintains the outside or what is called the “weather deck”.   Here you will see the massive crane on the back of the ship and two smaller cranes at the front.

They work the two large anchors and the “windlass” or winch to pull them up along with the smaller launches (boats) that are attached to the ship and the davits (hoists) to put them in and out of the water.  The deck crew also make sure the ship is moored (tied up) properly plus so much more.

EET and ET – These are the two smallest departments, but they are needed to keep everyone working.  The EET is the electronics engineering technician.  He is an electrician that takes care of all the wiring throughout the ship.  The Rainier EET has been here for over 20 years.  The ET is the electronics technician and he builds, maintains and programs the computers and servers that are needed to run Rainier.

Steward – Have you heard the term “laughter is the best medicine?”  Here on Rainier the food is the best medicine and what keeps this crew connected and happy!

The galley (kitchen) is incredibly clean, organized and delicious!  The selection of food has been healthy, varied and with just the right amount of sweet treats.  They are up very early and work later to keep this crew fed.  Every department has to come through here so they are the true backbone of the ship!

As I get to know the ship and crew more, I am continually amazed at the people here, how they communicate and work together and it all runs so smoothly.  I am looking forward to our upcoming adventures doing research around Kodiak Island.

Personal Log

Being chosen for this experience is a great honor for me.  I was here for only 24 hours and I had already seen so much of this beautiful area.  I was fortunate enough to get here the night before Labor Day so the crew and I had the day off.

I walked around the harbor town of Kodiak and then went hiking to Abercrombie State Park.  This now incredibly beautiful area of moss draped trees, cliffs and black rock/sand beaches was once a World War II gun site.  I saw the massive guns, the lookout that was half buried in the rock and the searchlight shelter.  Due to the northern site, there are times that the sun is not out for long so they had big searchlights that were rolled out of the structure to search for planes and ships out in the Pacific Ocean.  While there I got to see the resident Bald Eagles and other wildlife (no Kodiak bears yet but I keep looking).

Later, I was able to head to the southern shore of Kodiak Island to see where people surf on Surfer Beach.  Again, the sand is very dark and the waves were incredible.  I didn’t think Alaska was an area for surfing, but it is very popular.

The incredible Surfer Beach!

After looking at Surfer Beach I was taken over to the Pacific Spaceport Complex Alaska.  I was able to let my Space Geek out.  Too bad I didn’t have my Blue Flight Suit, I could have had my picture taken there.  This is an active launch pad for launches over the Arctic.  They had an explosion here in November, 2014 (no one was hurt thankfully) so it is being repaired before more launches can take place.

On the ship, the crew is incredibly welcoming and helpful.  I am gradually learning my way around and how things work.  Off the ship, I used the time to connect with the local Kodiak High School and their award winning robotics team.  They are doing some pretty amazing things here with STEAM in this small coastal town.

More adventures to follow as we head out and I become a true Teacher At Sea, not just a Teacher In Port!

Introduction

Town of Trumbull, Fairfield County , CT
Town of Trumbull, CT

My name is Kathleen Gibson and I bring you greetings from Trumbull, CT where live and teach. In two weeks I will travel to Pascagoula, MS, located on the Gulf of Mexico, to join NOAA Corps members, research scientists, and the crew aboard NOAA Ship Oregon II, as a  2015 NOAA Teacher at Sea.

I work at Trumbull High School and currently teach Biology to sophomores and two elective courses for seniors–Marine Science and AP Environmental Science.  I’m passionate about environmental education and am always looking for opportunities to engage students in the world outside of the classroom.  Trumbull has a large amount of protected green space, wetlands, streams and a river, and while we aren’t on the coast, we are only a few miles from Long Island Sound.  The woods and the shoreline have become our laboratory.

I’m open to adventures and new experiences that help me grow both personally and professionally.  I’m fortunate to have an awesome family, terrific colleagues and open-minded students who are willing to go along with my ideas; whether it be be hiking around volcanoes and rift zones, looking for puffins, or wading in nearby streams looking for life below.

About NOAA and Teacher at Sea

The National Oceanic and Atmospheric Administration (NOAA) is an agency within the United States Department of Commerce that seeks to enrich life through science.  While NOAA is somewhat familiar to many of us– thanks to the abundance of weather data that is collected and disseminated to the public–that’s not all that is happening  there. NOAA is working to increase our understanding of climate, weather and marine ecosystems, and to use this knowledge to better manage and protect these crucial ecosystems.  In addition to the abundant educational resources available to all teachers, NOAA provides unique opportunities for teachers and students.  The Teacher at Sea Program  brings classroom teachers into the field to work with world-renowned NOAA scientists.

The Mission

The Mission of the cruise I will be a part of is to monitor Shark and Red Snapper populations in the Gulf of Mexico in the Atlantic Ocean off the Florida coast. Data collected will be compared to findings from previous years, as a part of the ongoing research studying inter-annual variability of these populations. We are scheduled to embark on July 25, 2015 and plan to sail from Pascagoula, MS, down the west coast of Florida and up the Atlantic Coast as far as Mayport, FL.

I am honored to have been selected to be a Teacher at Sea for the 2015 Season  and look forward to a number of “firsts”. I’ve never been to Mississippi nor have I been at sea for more than 24 hours. Also, I’ve only experienced sharks as preserved specimens or through aquarium glass.  I’m also looking forward to meeting my shipmates and learning about career opportunities and the paths that led them to be a part of this Oregon II cruise. I’ll share as much as I can through future posts. I’m excited to bring my students and others along with me on this journey.

Next Up?

My next post to you should be coming later this month from off the Mississippi coast.  However, the first rule of being on board is FLEXIBILITY, so things may change.  Either way, I’ll keep you posted. In the meantime, please check out some of the TAS 2015 blogs written by my fellow NOAA Teachers at Sea, and spread the word. There is so much to learn.

Did You Know?

  • While some sharks release eggs into the water where they will later hatch, as many as 75% of shark species give birth to live young.
  • Shark babies are called pups.

Integrated Tracking of Aquatic Animals of the Gulf Coast

One of the best games you can play in the pool is Sharks and Minnows. The premise of this game is that you and your school are small fish that have to travel from one side of the pool to the other without getting caught by the shark. If you are caught you get turned into a shark for the next round.  Eventually the sharks are well distributed, preventing any minnows from getting through.

Acoustic Monitoring Arrays in the Florida Keys National Marine Sanctuary
Acoustic Monitoring Arrays in the Florida Keys National Marine Sanctuary

I am reminded of this as the fin fish team from FWC sets up a grand game of sharks and minnows for fisheries science.  Over the past week we have been setting up several arrays of acoustic receivers that catch tagged fishes’ signals as they swim through the Florida Keys reef system.  The plan is designed to capture fish moving within and between different parts of the ecosystem.  Any tagged fish coming into Florida Keys National Marine Sanctuary should come into contact with one of the receivers, as will any fish traveling out.  The placement of the receivers on the west and east of the sanctuary create and “entrance” and “exit” for tagged fish.

Within the sanctuary there are now several concentrated grids of receivers in places that make for good fish habitat (aka good fishing spots).  The VR2 receivers can record the identification number of the tagged fish as well as the time and date they connected to the receiver and their distance from the receiver.  When the receivers are collected, that data can be downloaded and a picture of fish movement created.  The data from the FWC’s arrays and tagged fish will be incorporated into a more extensive project called ITAG (Integrated Tracking of Aquatic Animals of the Gulf Coast).   In this project, collaborators share their acoustic tag data and receiver logs with each other, extending the reach of all project.   In the vastness of our marine environments, any one project will produce only a small snapshot of what is happening.  By collaborating between projects, the complexity of fisheries and ecosystems might be more easily untangled.

Today we set up individual stations of a new device which uses an acoustic release.  These are for much deeper sites containing “humps” which are relief features rising 100 to 200  feet about the surrounding sea floor.  Because of the relief, humps offer a large variety of habitats in a small amount of space, creating a highly diverse area for aquatic life.  Since these deeper areas are inaccessible to most divers, the receivers we set out can be triggered to return to the surface.  When data is ready to be collected in a few months, a device will be lowered into the water that communicates with the receiver using sound.  This device, called a VR100, can trigger the receivers to jettison themselves to the surface with the help of two small floats.  At that time the receivers can be collected from a small boat.

City in the Sea

The Nancy Foster has been at sea since February of this year.  While it resupplies every few weeks, most of the vital functions for human habitation are performed on board.  The ship is, for its officers, crew, and science passengers, a small floating city.

View of the engine room control panels.

Electricity requirements for a large ship are quite high.  If you factor in air conditioning, navigation systems, lighting, motors and pumps, kitchen, and scientific tools, the energy consumption equals a small hamlet.  Amazingly, this electricity is all created on board with the ship’s generator and a copious amount of marine diesel.

The Nancy Foster has a main engine for thrust but several others that act as generators for the thrusters, electricity, and backup power.
The Nancy Foster has a main engine and several others that act as generators for the thrusters, electricity, and backup power.

Food is loaded on at ports but that doesn’t mean it isn’t fresh and delicious.  Each day Bob and Lito prepare breakfast, lunch, and dinner for all of the scientists and crew.  These delicious multi-course meals keep all the members of this floating city very happy.  Just like the hungry generators, the humans energy levels are kept well stocked.

Water, water everywhere but not a drop to drink, except on the Nancy Foster you can just distill it using excess engine heat.
Water, water everywhere but not a drop to drink, except on the Nancy Foster you can just distill it using excess engine heat.

There is no sewage processing on board the ship.  Ship waste is carried in large tanks until it can be released into open ocean, far from land.  Once in the ocean, its nutrients are quickly consumed by hungry phytoplankton and converted into energy for the next level of the food chain.  Food waste is also separated from recycling and “garbage”.  Food waste, after being ground, is composted at sea.

With 40 people on board eating, showering, and using the head, the ship needs to produce water on a continual basis.  The ship keeps a reserve supply and when it goes down, The Nancy Foster has a device that uses excess heat from the engines and generators to distill water from the ocean.

Every day the Science Chief and project leaders determine a schedule and make staff assignments.
Every day the Science Chief and project leaders determine a schedule and make staff assignments.

Cities need organization and a specialized workforce to get all of these things done.  The NOAA Corps Officers make sure the ship stays on course and its mission objectives are met.  The ships crew ensures the small craft are launched safely, everyone is fed, and the ship keeps humming and running smoothly.  The science staff are visitors, enjoying all of the amenities of the ship while using its resources to complete their scientific missions.  Many of the science staff cruise with the Nancy Foster every year, while for some, it is their first time.

How did you get here?

I asked several of the scientists on board what they wanted to do when they were in middle school and how they became involved in marine science and research.  My middle school students are just starting to think about who they are and who they want to be.  I wanted to get some background information on how some of the scientists here got their start.

J. – A biologist had no clue what he wanted to do when he was in middle school and this trend continued until college! He loved fish and applied for an entry level fisheries job and has been at it ever since.

R. – Thinks she wanted to be a writer in middle school based on a paper she read from back then.  After pursuing her interest in ecology she is now writing about conservation issues for NOAA.

S. – She always loved science and math – After studying geology she had a chance to go to sea.  Loved it more than her geology work and now scans the sea floor of the Gulf of Mexico.  She won’t tell you where the treasure is!

P. – He took a test when he was in middle school that said he was not particularly interested in anything.  What he always liked was fish. After a couple related jobs he has worked in fisheries for many years.

S. – When he was in middle school he wanted to be rich and work in biology.  He now works in biology!

One of the major commonalities among the scientists is that they followed, or in some cases, rediscovered their interest.  As a teacher, I hope I can help my students find what they are passionate about.

The Golden Gate Bridge between the Pacific Ocean and San Francisco Bay

My name is Sandra Camp, and I teach math and science to 5th graders at Robert Louis Stevenson Elementary School in the Sunset neighborhood of San Francisco in northern California. San Francisco is located on a peninsula, which means it is surrounded by water on three sides. On the eastern part of the city lies San Francisco Bay. The western side is bordered by the Pacific Ocean. The famous Golden Gate Bridge spans the divide between these two large and important bodies of water.

The Pacific is sometimes called the “Mother of all Oceans” because it is the largest ocean on our planet. Although we have many beautiful beaches here, in San Francisco the Pacific Ocean is much too cold for humans to swim in. Even though I can’t swim in it, I do love to go tide pooling along the Pacific Ocean, looking for tiny sea creatures when the tide goes out like sea stars, crabs, and anemones.

Being surrounded by so much water makes us care a great deal about the health of the world’s oceans and the plants and animals that live there. In our part of the Pacific Ocean, there are giant kelp forests. We are also home to many different kinds of marine animals, such as sea otters, harbor seals, elephant seals, crabs, sea lions, bat rays, and sharks. When there are healthy populations of these creatures living off the coast of northern California, it indicates that our part of the Pacific Ocean is healthy.

I am very excited, because in about a week I will be visiting a different part of the Pacific Ocean, a part where the ocean is warm enough to swim in! Hawaii is a chain of islands located in the northern Pacific Ocean.  Unlike San Francisco, islands are surrounded on all sides by water, and because the ocean water there is warmer, it allows coral reefs to grow.  I will be flying to Honolulu, Hawaii where I will board the NOAA (National Oceanic and Atmospheric Administration) Ship Hi’ialakai at its home port in Pearl Harbor. Do any of you know what Pearl Harbor is famous for?  If so, write your answer to me in the comments section of this blog.  As a Teacher at Sea, I will spend 10 days aboard the ship while scientists conduct reef fish surveys around the main Hawaiian Islands. This means that they will be studying the fish that normally live in the coral reefs around the islands. If there are healthy populations of these fish in the reefs, then that means the coral reefs are healthy. If not, then that indicates the reefs are having problems. Here is a picture of the Hi’ialakai. Its name means “embracing pathways to the sea” in Hawaiian.

It takes a lot of people to run a ship this big.  Stay tuned, because in addition to the scientists, I will introduce some of the people who work aboard the ship to you in my upcoming blogs.

coral polyps

What exactly is a coral reef, anyway? Coral reefs are ecosystems located in warm, shallow ocean water that are home to a very diverse amount of sea creatures, including fish, crabs, turtles, octopus, sharks, eels, and shrimp. Reefs are structures that are made from the skeletons of colonies of tiny animals called coral. The individual animals that make up the colonies are called polyps.  Polyps usually have a cylindrical-shaped body with a mouth surrounded by tentacles at one end.  The polyps use these tentacles to catch tiny animals that drift by called zooplankton, which they eat for food.

The coral polyps have a symbiotic relationship with algae. The algae help corals build their skeletons, and the corals provide the algae with protection and compounds they need for photosynthesis. Coral reefs are the largest structures built by animals on Earth! Sadly, coral reefs around the world are in danger because of human factors like pollution, over-fishing, and global warming.

Most of the scientific work aboard the Hi’ialakai will be conducted by scientists who are scuba diving. While they are under the water, scientists can take pictures of the ocean floor and the coral reefs, as well as count the number of reef fish they find. The information they gather will help them determine if the reefs around Hawaii are healthy places for animals to live. I will be sharing a lot more about the work they do with you in the blogs I write while I am aboard the Hi’ialakai.

 


Did You Know?

The Great Barrier Reef off the coast of Australia is over 1400 miles long! Even though coral reefs are the largest structures built by animals and are home to so many diverse species, they cover less than one percent of the ocean floor.


Important Words

peninsula – a body of land surrounded on three sides by water

symbiotic – a relationship between two different species that benefits them both

polyp – the individual body of a coral animal, which is shaped like a cylinder, and has a mouth surrounded by tentacles at one end

Greetings from Austin, Texas.  In less than two weeks, my grand summer adventure begins.  I will be flying out of Austin, and heading to Boston where Peter Pan will magically transport me down the Woods (Rabbit?) Hole and out to sea aboard the R/V Hugh R. Sharp, where I will support scientists conducting a Sea Scallop Survey.

My Real Job

I teach at a fantastic public school in Austin that incorporates student interest surveys in lesson design and enrichment opportunities across subjects.  Although we are within the city of Austin, our campus backs up to a wildlife preserve (30,000 acres, total) that was set aside as land use patterns changed, and threatened habitat and ecosystems of 2 endangered birds, 8 invertebrates and 27 other species deemed “at risk.”  We have about 5 “wildspace” acres on our actual campus property that is unfenced to the larger Balcones Canyonlands Preserve.  We use that space as our own laboratory, and over the last decade, fifth grade students at our school have designed, constructed and continue to support the ecosystem through ponds supported by rainwater collection (yes, they are quite full at the moment!), a butterfly habitat, water-harvesting shelter/outdoor classroom, grassland/wildflower prairie and a series of trails.  In the spring, I post job descriptions for projects that need work in our Preserve and students formally apply for a job (i.e. – resume/cover letter).  They spend the balance of the spring working outdoors, conducting research relating to their job, and doing their part to develop a culture and heritage of sustainability on our campus that transcends time as students move beyond our campus during their educational journey.  My path through the curriculum is rooted in constructivist learning theory (project-based, place-based and service learning) and students are always outdoors.  Parents, of course, always get a huge “thank you” at the end of the year from me for not complaining that I’ve ruined too many pairs of shoes.

Below are a few pictures from our game cameras and shots I’ve taken of my classes in action this spring.

As I write, there are about 5 days left of this school year, which means that most of our big projects are complete and the rain has paused, so we’re spending a few days having a big “mechanical energy ball” competition (aka – “kickball”), and I get the distinct feeling that the students are quite prepared for their summer break!

My Background

I was an “oilfield kid” and grew up in Lafayette, Louisiana, the heart of Cajun Country, and about an hour’s drive to the Gulf of Mexico.  In college, I worked in the oilfield a bit, and after finishing law school, I was a maritime attorney, so I was able to spend some time aboard vessels for various purposes.  My time aboard the Hugh R. Sharp will be my longest stint aboard a vessel, and I’m quite excited for the work!

My Mission

R/V Hugh R. Sharp (btw students, it is a vessel or ship, not a “boat”) is a 146-foot general purpose research vessel owned by the University of Delaware (go Fighting Blue Hens!).  Each summer I get a travel coffee mug from the college where I attend a professional development course, and I’m hopeful I can find one with a picture of YoUDee on it this year!

While aboard the vessel, we will be conducting surveys to determine the distribution and abundance of scallops.  My cruise is the third (and northernmost) leg of the surveys, and we’ll spend our time dredge surveying, doing an image based survey using a tethered tow-behind observation vehicle, and some deeper water imaging of lobster habitat.  Those of you who know me, know that I am genuinely and completely excited and grateful for the opportunity to “nerd out” on this once-in-a-lifetime get-away-from-it-all adventure!  Check back over the summer and see what I’ve been up to!

Water Temperature:  5.8○ C

Science and Technology Log:

Earlier today I had planned to write about all of the safety features on board the Bigelow and explain how safe they make me feel while I am on board.  However, that was before our first sampling station turned out to be a monster haul!  For most stations I have done so far, it takes about an hour from the time that the net comes back on board to the time that we are cleaning up the wetlab.  At station 381, it took us one minute shy of three hours! So explaining the EEBD and the EPIRB will have to wait so that I can describe the awesome sampling we did at station 381, Cashes Ledge.

This is a screen that shows the boats track around the Gulf of Maine.  The colored lines represent the sea floor as determined by the Olex multibeam.  This information will be stored year after year until we have a complete picture of the sea floor in this area!
This is a screen that shows the boats track around the Gulf of Maine. The colored lines represent the sea floor as determined by the Olex multibeam. This information will be stored year after year until we have a complete picture of the sea floor in this area!

Before I get to describing the actual catch, I want to give you an idea of all of the work that has to be done in the acoustics lab and on the bridge long before the net even gets into the water.

The bridge is the highest enclosed deck on the boat, and it is where the officers work to navigate the ship.  To this end, it is full of nautical charts, screens that give information about the ship’s location and speed, the engine, generators, other ships, radios for communication, weather data and other technical equipment.  After arriving at the latitude and longitude of each sampling station, the officer’s attention turns to the screen that displays information from the Olex Realtime Bathymetry Program, which collects data using a ME70 multibeam sonar device attached to bottom of the hull of the ship .

Traditionally, one of the biggest challenges in trawling has been getting the net caught on the bottom of the ocean.  This is often called getting ‘hung’ and it can happen when the net snags on a big rock, sunken debris, or anything else resting on the sea floor.  The consequences can range from losing a few minutes time working the net free, to tearing or even losing the net. The Olex data is extremely useful because it can essentially paint a picture of the sea floor to ensure that the net doesn’t encounter any obstacles.  Upon arrival at a site, the boat will cruise looking for a clear path that is about a mile long and 300 yards wide.  Only after finding a suitable spot will the net go into the water.

Check out this view of the seafloor.  On the upper half of the screen, there is a dark blue channel that goes between two brightly colored ridges.  That's where we dragged the net and caught all of the fish!
Check out this view of the seafloor. On the upper half of the screen, there is a dark blue channel that goes between two brightly colored ridges. We trawled right between the ridges and caught a lot of really big fish!

The ME70 Multibeam uses sound waves to determine the depth of the ocean at specific points.  It is similar to a simpler, single stream sonar in that it shoots a wave of sound down to the seafloor, waits for it to bounce back up to the ship and then calculates the distance the wave traveled based on the time and the speed of sound through the water, which depends on temperature.  The advantage to using the multibeam is that it shoots out 200 beams of sound at once instead of just one.  This means that with each ‘ping’, or burst of sound energy, we know the depth at many points under the ship instead of just one.  Considering that the multibeam pings at a rate of 2 Hertz to 0.5 Herts, which is once every 0.5 seconds to 2 seconds, that’s a lot of information about the sea floor contour!

This is what the nautical chart for Cashes Ledge looks like. The numbers represent depth in fathoms.  The light blue lines are contour lines.  The places where they are close together represent steep cliffs.  The red line represents the Bigelow’s track. You can see where we trawled as a short jag between the L and the E in the word Ledge

The stations that we sample are randomly selected by a computer program that was written by one of the scientists in the Northeast Fisheries Science Center, who happens to be on board this trip.  Just by chance, station number 381 was on Cashes Ledge, which is an underwater geographical feature that includes jagged cliffs and underwater mountains.  The area has been fished very little because all of the bottom features present many hazards for trawl nets.  In fact, it is currently a protected area, which means the commercial fishing isn’t allowed there.  As a research vessel, we have permission to sample there because we are working to collect data that will provide useful information for stock assessments.

My watch came on duty at noon, at which time the Bigelow was scouting out the bottom and looking for a spot to sample within 1 nautical mile of the latitude and longitude of station 381.  Shortly before 1pm, the CTD dropped and then the net went in the water.  By 1:30, the net was coming back on board the ship, and there was a buzz going around about how big the catch was predicted to be.  As it turns out, the catch was huge!  Once on board, the net empties into the checker, which is usually plenty big enough to hold everything.  This time though, it was overflowing with big, beautiful cod, pollock and haddock.  You can see that one of the deck crew is using a shovel to fill the orange baskets with fish so that they can be taken into the lab and sorted!

At this point, I was standing at the conveyor belt, grabbing slippery fish as quickly as I could and sorting them into baskets.  Big haddock, little haddock, big cod, little cod, pollock, pollock, pollock.  As fast as I could sort, the fish kept coming!  Every basket in the lab was full and everyone was working at top speed to process fish so that we could empty the baskets and fill them up with more fish!  One of the things that was interesting to notice was the variation within each species.  When you see pictures of fish, or just a few fish at a time, they don’t look that different.  But looking at so many all at once, I really saw how some have brighter colors, or fatter bodies or bigger spots.  But only for a moment, because the fish just kept coming and coming and coming!

Finally, the fish were sorted and I headed to my station, where TK, the cutter that I have been working with, had already started processing some of the huge pollock that we had caught.  I helped him maneuver them up onto the lengthing board so that he could measure them and take samples, and we fell into a fish-measuring groove that lasted for two hours.  Grab a fish, take the length, print a label and put it on an envelope, slip the otolith into the envelope, examine the stomach contents, repeat.

Some of you have asked about the fish that we have seen and so here is a list of the species that we saw at just this one site:

  • Pollock
  • Haddock
  • Atlantic wolffish
  • Cod
  • Goosefish
  • Herring
  • Mackerel
  • Alewife
  • Acadian redfish
  • Alligator fish
  • White hake
  • Red hake
  • American plaice
  • Little skate
  • American lobster
  • Sea raven
  • Thorny skate
  • Red deepsea crab

 

 

 

 

I think it’s human nature to try to draw conclusions about what we see and do.  If all we knew about the state of our fish populations was based on the data from this one catch, then we might conclude that there are tons of healthy fish stocks in the sea.  However, I know that this is just one small data point in a literal sea of data points and it cannot be considered independently of the others.  Just because this is data that I was able to see, touch and smell doesn’t give it any more validity than other data that I can only see as a point on a map or numbers on a screen.  Eventually, every measurement and sample will be compiled into reports, and it’s that big picture over a long period of time that will really allow give us a better understanding of the state of affairs in the ocean.

It seems like time is passing faster and faster on board the Bigelow.  I have been getting up each morning and doing a Hero’s Journey workout up on the flying bridge.  One of my shipmates let me borrow a book that is about all of the people who have died trying to climb Mount Washington.  Today I did laundry, and to quote Olaf, putting on my warm and clean sweatshirt fresh out of the dryer was like a warm hug!  I am getting to know the crew and learning how they all ended up here, working on a NOAA ship.  It’s tough to believe but a week from today, I will be wrapping up and getting ready to go back to school!

Aboard NOAA Ship Oscar Dyson

July 26 – August 13, 2014

Mission: Annual Walleye Pollock Survey

Geographical Area: Bering Sea

Date: August 10, 2014


Science and Technology Log:

Last night and afternoon was by far the craziest we’ve seen on the Oscar Dyson. The winds were up to 35 knots (about 40 miles an hour). The waves were averaging 12 feet in height, and sometimes reaching 15-18 feet in height. Right now I’m sitting on the bridge and waves are around 8 feet. With every rise the horizon disappears and I’m looking up at stark grey clouds. With every drop the window fills with views of the sea, with the horizon appearing just below the top of the window frames.

UpDownUpDownUpDown
In the space of three seconds, the view from atop the bridge of the Oscar Dyson goes from looking up to the sky to down at the sea. The above pic is a MILD example.

Ensign Gilman, a member of NOAA Corps, explains to me how the same thing that makes the Bering Sea good for fish makes things rough for fishermen.

“This part of the Bering Sea is shallow compared to the open ocean. That makes the water easier for the wind to pick up and create waves. When strong winds come off Russia and Alaska, it kicks up a lot of wave action,” Ensign Gilman says.

Andrew, Bill and Nate
Lt. Andrew Ostapenko, Survey Tech Bill Potts, and Ens. Nathaniel Gilman on the Bridge

“It’s not so much about the swells (wave height),” he continues. “It’s about the steepness of the wave, and how much time you have to recover from the last wave.” He starts counting between the waves… “one… two… three… three seconds between wave heights… that’s a pretty high frequency. With no time to recover, the ship can get rocked around pretty rough.”

Rough is right! Last night I got shook around like the last jelly bean in the jar. I seriously considered finding some rope to tie myself into my bunk. There were moments when it seemed an angry giraffe was jumping on my bunk. I may or may not have shouted angrily at Sir Isaac Newton that night.

Which brings us to Sea Sickness.

Lt. Paul Hoffman, a Physician’s Assistant with the U.S. Public Health Service, explains how sea sickness works.

“The inner ears are made up of tubes that allow us to sense motion in three ways,” Hoffman explains. “Forward/back, left/right, and up/down. While that’s the main way our brain tells us where we are, we use other senses as well.” He goes on to explain that every point of contact… feet and hands, especially, tell the brain more information about where we are in the world.

“But another, very important piece, are your eyes. Your eyes are a way to confirm where you are in the world. Sea Sickness tends to happen when your ears are experiencing motion that your eyes can’t confirm,” Hoffman says.

For example, when you’re getting bounced around in your cabin (room), but nothing around you APPEARS to be moving (walls, chair, desk, etc) your brain, essentially, freaks out. It’s not connected to anything rational. It’s not enough to say “Duhh, brain, I’m on a boat. Of course this happens.” It happens in a part of the brain that’s not controlled by conscious thought. You can’t, as far as I can tell, think your way out of it.

Hoffman goes on to explain a very simple solution: Go look at the sea.

“When you get out on deck, the motion of the boat doesn’t stop, but your eyes can look at the horizon… they can confirm what your ears have been trying to tell you… that you really are going up and down. And while it won’t stop the boat from bouncing you around, your stomach will probably feel a lot better,” Hoffman says.

The Deck is your Friend.
Everything is easier on deck! Clockwise from left: Winch Operator Pete Stoeckle and myself near Cape Navarin, Russia. Oceanographer Nate Lauffenburger and myself crossing the International Date Line. Survey Tech Alyssa Pourmonir and Chief Scientist Taina Honkalehto near Cape Navarin, Russia.

And he’s right. Being up on the bridge… watching the Oscar Dyson plow into those stout waves… my brain has settled into things. The world is back to normal. Well, as normal as things can get on a ship more than a third of the way around the world, that is.

Personal Log:

Let’s meet a few of the good folks on the Oscar Dyson. 

NOAA Crew Member Alyssa Pourmonir

Job Title: Survey Technician

Alyssa and the Giant Jelly!
Survey Tech Alyssa Pourmonir assesses a giant jelly fish!

Responsibilities on the Dyson: “I’m a liaison between crew and scientists, work with scientists in the wet lab, put sensors onto the trawling nets, focus on safety, maintaining all scientific data and equipment on board.” A liaison is someone who connects two people or groups of people.

Education Level Required: “A Bachelors degree in the sciences.” Alyssa has a BS in Marine and Environmental Science from SUNY Maritime with minors in oceanography and meteorology.

Job or career you’ve had before this: “I was a life guard/swim instructor in high school, then I was in the Coast Guard for three years. Life guarding is the BEST job in high school!”

Goal: “I strive to bring about positive change in the world through science.”

Weirdest thing you ever took out of the Sea: “Lump Sucker: They have big flappy eyebrows… they kinda look like a bowling ball.”

Lump Sucker!
Lump Sucker! When provoked, this fish sucks in so much water that it becomes too big for most other fish to swallow. That’s its defense mechanism! It sort of looks like a cross between a bowling ball and grumpy cat!

Dirtiest job you’ve ever had to do on a ship: “Sexing the fish (by cutting them open and looking at the fish’s gonads… sometimes they explode!) is pretty gross, but cleaning the PCO2 filter is nasty.  There are these marine organisms that get in there and cling to the filter and you have to push them off with your hands… they get all slimy!”

Engineer Rico Speights
Engineer Rico Speights shows off how nasty a filter can be! He and his wife (Chief Steward Ava) sail the Bering Sea together with NOAA!

NOAA Rotating Technician Ricardo Guevara

Job Title: Electronics Technician

Responsibilities on the Dyson: “I maintain and upkeep most of the low voltage electronics on the ship, like computer networking, radio, television systems, sensors, navigation systems. All the equipment that can “talk,” that can communicate with other devices, I take care of that.”

Education level Required: High school diploma and experience. “I have a high school diploma and some college. The majority of my knowledge comes from experience… 23 years in the military.”

Tech Guevara
Technician Ricardo Guevara shows me an ultrasonic anemometer… It can tell the wind speed by the time it takes the wind to get from one fork to the other.

Job or career you’ve had before this: “I was a telecommunications specialist with the United States Air Force… I managed encryption systems and associated keymat for secure communications.” This means he worked with secret codes.

Trickiest problem you’ve solved for NOAA: “There was a science station way out on the outer edge of the Hawaiian Islands that was running their internet off of dial-up via satellite phone when the whole thing shut down on them… ‘Blue Screen of Death’ style. We couldn’t just swap out the computer because of all the sensitive information on it. I figured out how to repair the disk without tearing the machine apart. Folks were extremely happy with the result… it was very important to the scientists’ work.”

What are you working on now? “I’m migrating most of the ship’s computers from windows xp to Windows 7. I’m also troubleshooting the DirecTV system. The problem with DirecTV is that the Multi-Switch for the receivers isn’t communicating directly with the satellite. Our antenna sees the satellite, but the satellite cannot ‘shake hands’ with our receiver system.” And that means no Red Sox games on TV! Having entertainment available for the crew is important when you’re out to sea for two to three weeks at a time!

What’s a challenging part of your job on the Dyson? “I don’t like it, but I do it when I have to… sometimes in this job you have to work pretty high up. Sometimes I have to climb the ship’s mast for antenna and wind sensor maintenance. It’s windy up there… and eagles aren’t afraid of you up there. That’s their place!”

Lt. Paul Hoffman

Job Title: Physician Assistant (or P.A.) with the U.S. Public Health Service

Paul and Peggy
Lt. Paul Huffman and the small boat Peggy D behind him. Lt. Huffman is with the U.S. Public Health Service. But secretly I call him the Bat Man of Health Care. Peggy Dyson is a beloved part of the Alaska Fishing Industry’s history. Before the internet and satellite telephones, her radio service served as a vital link home for fishermen out at sea.  She was married to Oscar Dyson, the man for whom the ship was named.

Responsibilities on the Dyson: He’s effectively the ship’s doctor. “Whenever a NOAA ship travels outside 200 miles of the U.S. coast, they need to be able to provide an increased level of medical care. That’s what I do,” says Hoffman.

Education required for this career: “Usually a Masters degree from a Physician’s Assistant school with certification.”

Job or career you’ve had before this: “Ten and a half years in the U.S. Army, I started off as an EMT. Then I went on to LPN (Licensed Practical Nurse) school, and then blessed with a chance to go on to PA school. I served in Iraq in 2007-2008, then returned for 2010-2011.”

Most satisfying thing you’ve seen or done in your career: “Knowing that you personally had an impact on somebody’s life… keeping somebody alive. We stabilized one of our soldiers and then had a helicopter evac (evacuation) under adverse situations. Situations like that are what make being a PA worthwhile.”

Could you explain what the Public Health Service is for folks that might not be familiar with it?

“The Public Health Service is one of the seven branches of the U.S. Military. It’s a non-weaponized, non-combative, all-officer corps that falls under the Department of Health and Human Services. We’re entirely medical related. Primary deployments (when they get sent into action) are related to national emergency situations… hurricanes, earth quakes… anywhere where state and local resources are overrun… they can request additional resources… that’s where we step in. Hurricane Katrina, the Earthquake in Haiti… a lot of officers saw deployment there. Personally, I’ve been employed in Indian Health Services in California and NOAA’s Aircraft Operations Center (AOC)… they’re the hurricane hunters,” Hoffman concludes.

Kids, when you’ve been around Lt. Hoffman for a while, you realize “adverse conditions” to him are a little tougher than a traffic jam or missing a homework assignment. I’ve decided to call him, and the rest of the Public Health Service, “The Batman of Health Care.” When somebody lights up the Bat Signal, they’re there to help people feel better.

Coming up next: International Teamwork!

“Whatever,” you shrug.
“Just a fish,” you scorn.
“He’s slimy and has fish for brains,” you mock.
Well, what if I told you that guy there was worth almost one billion dollars in exports alone?
What if I told you that thousands of fishermen rely on this guy to provide for their families?
What if I told you that they were the heart of the Sub-Arctic food web, and that dozens of species would be threatened if they were to disappear?
What if I told you they were all secretly trained ninja fish? Ninja fish that carry ninja swords strapped to their dorsal fins?
Then I’d only be wrong about one thing.


Taina Honkalehto is the Chief Scientist onboard the Oscar Dyson. She has been studying Pollock for the last 22 years. I asked her what was so important about the fish.

“They’re the largest single species fishery in North America,” Taina says. That makes them top dog…err… fish… in the U.S. fishing industry.

Chief Scientist Taina Honkalehto decides where to fish based on data.
Chief Scientist Taina Honkalehto decides where to fish based on data.

“In the U.S. they are fish sticks and fish-wiches (like Filet-o-Fish from McDonalds). They’ve become, foodwise, what Cod used to be… inexpensive, whitefish protein,” Taina continues. They’re also the center of the sub-arctic food web. Seals, walruses, orca, sea lions, and lots of larger fish species rely on Pollock as an energy source.”
But they aren’t just important for America. Pollock plays an important role in the lives of people from all over the Pacific Rim. (Remember that the Pacific Rim is made up of all the countries that surround the Pacific Ocean… from the U.S. and Canada to Japan to Australia to Chile!)

Pollock Need Love, too!
Pollock Need Love, too!

“Pollock provide a lot of important fish products to many countries, including the U.S., Japan, China, Korea, and Russia,” Honkalehto says.

Making sure we protect Pollock is REALLY important. To know what can go wrong, we only have to look at the Atlantic Cod, the fish that Cape Cod was named after. In the last twenty years, the number of Atlantic Cod has shrunk dramatically. It’s cost a lot of fishermen their jobs and created stress in a number of families throughout New England as well as tensions between the U.S. and Canada. The U.S. and Canada share fish populations.

The primary job of the Oscar Dyson is to sample the Pollock population. Government officials use the results to tell fishermen what their quota should be. A quota is a limit on the number of fish you can catch. The way we gather that data, though, can be a little gross.

The Aleutian Wing Trawl (or AWT)

Fishermen Deploy the AWT

The fishermen guide the massive Aleutian Wing Trawl (or AWT) onto the deck of the ship. The AWT is a 150 meters long net (over one and a half football fields in length) that is shaped like an ice cream cone. The net gets more and more narrow until you get all the way down to the pointy tip. This is known as the “cod end,” and it’s where most of the fish end up. Here’s a diagram that XO (Executive Officer) Kris Mackie was kind enough to find for me.

The Aleutian Wing Trawl (or AWT). over one and a half football fields worth of Pollock-Snatching Power.

The AWT is then hooked onto a crane which empties it on a giant mechanical table. The table has a hydraulic lift that lets us dump fish into the wet lab.

Kids, whenever you hear the term “wet lab,” I don’t want you to think of a water park. Wet lab is going to mean guts. Guts and fish parts.

In the wet lab, the contents of the net spills onto a conveyer belt… sort of like what you see at Shaw’s or Market Basket. First we sift through the Pollock and pull any odd things… jellyfish, skates, etc… and set them aside for measurement. Then it’s time to find out what sex the Pollock are.

Genitals on the Inside!

Pollock go through external fertilization (EF). That means that the female lays eggs, and the males come along and fertilize them with their sperm. Because of that, there’s no need for the outside part of the sex organs to look any different. In science, we often say that form follows function. In EF, there’s very little function needed other than a hole for the sperm or egg cells to leave the body.

Because of that, the only way to tell if a Pollock is male or female is to cut them open and look for ovaries and testes. This is a four step process.

Ladies before Gentlemen: The female Pollock (in the front) has ovaries that look like two orange lobes. The Male (in the back) has structures that make him look like he ate Ramen noodles for dinner.
Ladies before Gentlemen:
The female Pollock (bottom) has ovaries that look like two orange lobes. The Male (itop) has testes that make him look like he ate Ramen noodles for dinner.

Step 1: Slice open the belly of the fish.

Step 2: Push the pink, flippy floppy liver aside.

Step 3: Look for a pair of lobes (a bag like organ) that is either purple, pink, or orange-ish. These are the ovaries! If you find this, you’ve got a female.

Step 4: If you strike out on step 3, look for a thin black line that runs behind the stomach. These are the testes… As Tom Hanks and Meg Ryan might say, you’ve got male.

Then the gender and length of the fish is then recorded using CLAMS… a software program that NOAA computer scientists developed for just this purpose. With NOAA, like any good science program, it’s all about attention to detail. These folks take their data very seriously, because they know that so many people depend on them to keep the fish population safe.

Safety!

Lobster Gumby
Your teacher in an Immersion Suit. Sailors can survive for long periods of time in harsh environments in these outfits.

.

On the first day aboard the Oscar Dyson, we were trained on all matters of safety. Safety on a ship is often driven by sirens sounded by the bridge. Here’s a list of calls, what they mean, and what you should do when you hear them:

What you hear… What it means… What you should do…
 Three long blasts of the alarm: Man Over Board Report to safety station, be counted, and report in to the bridge (unless you’re the one that saw the person go overboard… then you throw them life rings (floaties) and keep pointing at them).
 One long blast of general alarm or ship’s whistle: Fire or Emergency onboard Report to safety station, be counted, and report in to the bridge. Bring Immersion Suit just in case.
 Six or more short blasts then one long blast of the alarm: Abandon Ship Grab your immersion suit, head to the aft (back) deck of the ship, be counted, and prepare to board a life raft.

 

The immersion suit (the thing that makes me look like lobster gumby, above) is made of thick red neoprene. It has two flashing lights also known as beacons…  one of them automatically turns on when it hits water! This helps rescuers find you in case you’re lost in the dark. It also has an inflatable pillow behind your head to help keep your head above water. Mostly just wanted to wear it to Starbucks some day.

Food!

Another thing I can tell you about life aboard the Oscar Dyson is that there is plenty to eat!

kind of awesome. For one thing, there is a never ending supply of food in the galley (the ship’s cafeteria). Eva is the Chief Steward on the Oscar Dyson (though I call her the Head Chef!).

Chief Steward Eva gets dinner done right!
Chief Steward Eva gets dinner done right!

You’ll never go hungry on her ship. Dinner last night? barbeque ribs and mac and cheese. Yesterday’s lunch? Steak and chicken fajitas. And this morning? Breakfast burritos with ham and fruit. I know. You were worried that if I lost any weight at sea that I might just disappear. I can confirm for you that this is absolutely not going to happen.

Tune in next time when I take you on a tech tour of the Oscar Dyson!

There is truly so much to learn on the Oregon II. It’s almost like a small city with all the jobs everyone has, food preparation on board, safety drills, and a community of people working together to make everything successful. I am working the noon to midnight shift and am partnered with kind, intelligent team members that are helping me learn what it takes to work for NOAA. Our team consists of Michael, Mark, and Brittany. Each has so much knowledge of marine animals that I certainly feel like I have much to learn. It’s pretty amazing how they know the scientific names of most animals and plants we come across while trawling from the Oregon II.

I'm dressed in a survival suit looking a bit like an orange Gumby.  These survival suits would protect us from hypothermia if we needed to abandon ship. In order to wear these, you must lay the suit flat on the floor and crawl into it. It took Ensign Laura Dwyer, a Junior Officer, and me working together to get it on. I really was tempted to Sumo wrestle with it on!

I really was tempted to Sumo wrestle with it on!

When it was time to “haul back” the net that was trawling for fish, everyone rushed to get to work. The trawl caught a wide variety of fish, shells, and plants. In the wet lab, all the scientists quickly began sorting the fish into baskets and began identifying them. The data must be entered into the computer with the name of the fish, quantity, weight, etc. On the rare occasion they may not be able to identify the plant or animal immediately, they refer to descriptive books such as Fishes of the Gulf of Mexico.

Scientist Spotlight: Meet Brittany Palm-She really knows her “stuff” and she is so helpful in explaining everything to me so I can understand. Brittany is a Fisheries Biologist and will soon begin to work on her PhD. Brittany explained the CTD device to me. It measures conductivity, temperature, and depth. It soaks at the surface for 3 minutes to calibrate and flush out sensors. The CTD is then sent from the surface of the water to the bottom and then back up to the surface. It records environmental data for the scientists.

Science and Technology Log: Bottom Trawling

The Oregon II is a participant and contributor to SEAMAP (The Southeast Area Monitoring and Assessment Program) which monitors the biodiversity of marine life in the Gulf of Mexico. The primary way the Oregon II assists SEAMAP is by conducting bottom trawls with a 42 foot semi-balloon shrimp trawl net.The net is slowly lowered into the ocean until it reaches the bottom and is then dragged along the ocean floor for thirty minutes. The net has a tickler chain between the doors which scrapes the bottom of the ocean floor and flicks objects into the net. The net is then brought to the surface and all of the organisms inside are put into baskets (see video above). The total weight of the catch is massed on scales on the deck. If the catch is large (over 20 kilos), it is dumped onto a conveyor belt and a random sub-sample (smaller) is kept, along with any unique species while the rest of the catch is dumped overboard.

Shrimp Net

Once the sample has been selected, the marine organisms are sorted by species and put into baskets. Each species is then massed and counted while the data is recorded into a system called FSCS (Fisheries Scientific Computer System). To obtain a random sampling, every fifth individual of the species (up to twenty) is measured, massed and sexed (more on this later). Once the data has been verified by the watch manager, the marine organisms are put back into the ocean. The following are pictures of a sample on the conveyor belt and the organisms divided into a few species.

The sorting process for shrimp (white, brown and pink) differs slightly from that of the other marine organisms. Every shrimp (up to 200 of each species), is massed, measured and sexed.This data is then used by various government agencies such as the Fish and Wildlife Service, Gulf of Mexico and South Atlantic Fishery Management Councils, etc… to determine the length of the shrimping season and to set quotas on the amount that can be caught by each issued license. States will not open the shrimping season until SEAMAP reports back with their findings from NOAA’s shrimp survey.

The shrimp trawl net used on the Oregon II differs from a shrimp net used on a commercial boat in two main ways. Commercial shrimping boats have BRD’s (Bycatch Reduction Devices) and TED’s (Turtle Excluder Devices). BRD’s and TED’s are federally required in the U.S. to reduce the amount of bycatch (unintentionally caught organisms) and sea turtles. Shrimping boats typically trawl for hours and turtles cannot survive that long without air. TED’s provide turtles and other large marine organisms an escape hatch so that they do not drown (see the video below). Unfortunately, larger turtles such as Loggerheads are too big to fit through the bars in a TED. Additionally, TED’s may become ineffective if they are clogged with sea debris, kelp or are purposefully altered.

Warren is a gear specialist who is working as a member of the scientific party. He is contracted by Riverside for NOAA.  While aboard the Oregon II, Warren designs, builds and repairs gear that is needed on the boat. Unfortunately, on this leg of the trip either sharks or dolphins have been chewing holes in the nets to eat the fish inside. This means Warren has spent a large chunk of his time repairing nets.

Warren is not a crew member of the Oregon II  and actually works at the Netshed in Pascagoula where he spends his time working with TED’s. He has law enforcement training and will go out with government agencies (such as the Coast Guard or Fish and Wildlife Service) to monitor TED’s on shrimping boats. He also participates in outreach programs educating fishermen in measuring their nets for TED’s, installing them. Warren will bring TED’s and nets to make sure that every everyone at the training has a hands on experience installing them. While he regularly does outreach in Alabama, Mississippi, Florida, Georgia, North Carolina and Texas, his work has also taken him as far as Brazil.

Robin Gropp:

Robin will be a junior at Lewis & Clark College in the Fall. He is currently an intern aboard the Oregon II. Robin received a diversity internship through the Northern Gulf Institute and is one of eight interns for NOAA. For the first two weeks Robin worked at the NOAA lab participating in outreach at elementary school science fairs. He brought sea turtle shells and a shrimp net with a TED installed. The students were very excited to pretend to be sea turtle and run through the TED. They proclaimed, “we love sea turtles.”  After leaving the Oregon II, Robin will return to the NOAA lab to study the DNA of sharks.

 

Personal Log:

Overall I have had a hard time processing and accepting the groundfish survey portion of the trip. I am a vegetarian that does not eat meat, including fish, for ethical and environmental reasons. Yet here I find myself on a boat in the Gulf of Mexico surveying groundfish so that others can eat shrimp. A large part of me feels that I should be protesting the survey rather than assisting. Because of this I spent a lot of time talking to the other scientists on my watch and Chief Scientist Andre Debose. After many discussions (some still ongoing) I do realize how important the groundfish survey is. Without it, there would be no limits placed on the fishing industry and it is likely that many populations of marine organisms would be hunted to extinction more rapidly than they are now. This survey actually gives the shrimp species a chance at survival.

Science and Technology Log

Science Part I.  The superhighway under the surface: sea currents

Until today, most everything including the weather and sea conditions were in our favor.  On the surface it just looks like waves (ok well big waves) but underneath is a superhighway.  On Sunday morning the currents throughout the water column were very strong.  The result was the ROV and its power and fiber optic umbilical cord never reached a true vertical axis.  Even with a 300lbs down-weight and five thrusters the ROV could not get to our desired depth of about 60m.  The current grabbed its hold onto the thin cable and stretched it diagonally far under the ship – a dangerous situation with the propellers.  The skill of ROV pilots Lance and Jason and the crew on the bridge navigated the challenging situation and we eventually retrieved the ROV back to the deck.  I presume if I were back home on Goose Lake in Minnesota, I certainly would have ended up with the anchor rope wrapped around the props in a similar situation.  So, where is the current coming from and how do we measure it aboard the Nancy Foster?

The Gulf Stream.  Note the direction of the current and consider that on Sunday morning we were due east of North Carolina.
The Gulf Stream. Note the direction of the current and consider that on Sunday morning we were due east of North Carolina.

Answer: The Gulf Stream is an intense, warm ocean current in the western North Atlantic Ocean and it moves up the coast from Florida to North Carolina where it then heads east.  You don’t have to be directly in the Gulf Stream to be affected by its force; eddies spin off of it and at times, water will return in the opposite direction on either side of it.  Visit NOAA Education for more on ocean currents.

Answer: Aboard the Nancy Foster, we have a Teledyne ADCP – Acoustic Doppler Current Profiler.  The ADCP measures direction, speed, and depths of the currents between the ship and the ocean floor.  It’s not just one measurement of each; currents may be moving in different directions, at different depths, at different speeds.  This can make a ROV dive challenging.

For example, at 4pm on Sunday near the Snowy Grouper MPA site off the coast of North Carolina, from 0-70 meters in depth the current was coming from the north and at about 2 knots. At 70 meters to the sea floor bottom it was coming from the south at over 2 knots.  Almost completely opposite.

Hydrphone
Hydrophone

Another indication of the strong currents today was the force against the hydrophone. Hydrophones detect acoustic signals in the ocean.  We are using a hydrophone mounted on the side of the Nancy Foster to communicate the location of the ROV to the ship.  The hydrophone has to be lowered and secured to the ship before each dive.  It ended up in my blog today because the current was so strong, three of us could not swing and pull the hydrophone to a vertical position in the water column.  It was a good indicator the currents were much stronger than the past few days.

 

Science Part II.  Discoveries of Dives in the Deep

Snowy Grouper – one primary species we are on the hunt for this mission

Snowy Grouper are one of the species requiring management due to low and threatened stock levels within the federal 200-mile limit of the Atlantic off the coasts of North Carolina, South Carolina, Georgia and east Florida to Key West.  The MPAs help conserve and manage these species.  We were excited to have a few visit the camera lens the past two days.

Science Part III.  Rugosity- 

Rugosity is sea- bottom roughness.  Probably one of the terms and skills I will remember most about this experience.  In oceanography, rugosity is determined in addition to the other characteristics I am more accustomed to:  slope, composition, and the cover type (plants, animals, invertebrates.)  It was a little challenging for me to incorporate this into my observations the first few days so thought I would share two of the stark differences.   This compliments my strong knowledge and passion for teaching earth science with Earth AdventureI cannot wait to use this content in future Earth Balloon & Earth Walk Programs!

Science Part III.  Day Shapes

When a ship has restricted ability to move, the ship displays vertically (up to down) from the mast a black ball, diamond, and black ball.  This informs other ships and vessels in the area not to approach the Nancy Foster as we can’t move; the ROV is in the water.  While radio communication is an option, this is a marine standard that signals others to stay away.  If we were deploying the ROV at night, a series of lights communicate the same message.  On Sunday morning, we observed three recreational fishing boats probably a 1.5 kilometers from the ship.  It seemed one was moving towards us likely interested in what was happening aboard the giant Nancy Foster.

Personal Log:

A week without television.  While I brought movies on my iPad and there is a lounge equipped with more than nine leather recliners, a widescreen, and amazing surround sound, I haven’t yet sat down long enough to watch anything.  I spend 12 hours a day being a shadow to the researches trying to absorb as much as I can and lending a hand in anything that can help the mission. Most of my evenings have been consumed by researching species we saw during the dives using taxonomy keys and well, just asking a lot of questions.  I go through hundreds of digital pictures from the ROV and try to make sense of the many pages of notes I make as the researchers discuss species, habitats, and characteristics during the dives. While I am using a trust book version as well as the multiple poster versions scattered on the walls in the lab, here is a great online key.

Sunday evening, crew members of the Nancy Foster invited me to join them in a game of Mexican Train – a game using Dominos.  Thanks Tim for including me!  I am going to have to purchase this for cabin weekends up north in Minnesota (when the mosquitoes get so large they will carry you away and we can no longer go out in the evenings).

When the Acoustic Doppler Current Profiler wasn’t working, we just called on King Neptune and his kite to help us gauge the wind speed, direction and the currents.  Wait, I thought he carried a scepter?

I made it a little more progress reading The Big Thirst by Charles Fishman.

Science and Technology Log

Today’s blog is all about post processing, or “cleaning up” the data and being on night shift.  It is a balmy, sliver moon night at port here, in Kodiak.  We have come a long way in the last two weeks, during which survey crews have been working hard to finalize a Cold Bay report from last season before they devote themselves entirely to North Kodiak Island. I am in the plot room with Lieutenant Junior Grade Dan Smith who is on Bridge Duty from midnight until 4 a.m. with Anthony Wright, Able Seaman.

People work around the clock on Rainier whether it be bridge watch, processing data, or in the engine room.  One thing that makes the night shift a little easier is that there is no shortage of daylight hours in Alaska: within two months, there will be less than an hour of complete darkness at night.

In previous blogs, I described how the team plans a survey, collects and processes data.  In this blog, I will explain what we do with the data once it has been processed in the field. Tonight, Lieutenant Dan Smith is reviewing data collected in Sheet 5, of the Cold Bay region on the South Alaskan Peninsula.  In September, 2013, the team surveyed this large, shallow and therefore difficult to survey area.  The weather also made surveying difficult.  Despite the challenges, the team finished collecting data for Sheet 5 and are now processing all the data they collected.

Cold Bay Sheet Map
Cold Bay Sheet Map.  Recall the shallow areas are shaded light blue, and as you can see much of the north end of Sheet 5 is blue.

While I find editing to be one of the most challenging steps in the writing process, it is also the most rewarding.  Through the editing process, particularly if you have a team, work becomes polished, reliable and usable.  The Rainier crew reviews their work for accuracy as a team and while Sheet 5 belongs to Brandy Geiger, every crew member has played a part in making the Sheet 5 Final Report a reality, almost.  On the left screen, Lieutenant Smith is looking at one line of data.  Each color represents a boat, and each dot represents the data from one boat, and each dot represents a depth measurement  computed by the sonar. The right screen shows which areas of the map he has already reviewed in green and the areas he still needs to review in magenta.

While the plot room is calm today in Kodiak, there have been times when work conditions are challenging, at best.

.

The crew continues on, despite the weather, so long as work conditions are safe.

Several days ago, Lieutenant Smith taught me the difference between a sonar ping that truly measured depth, and other dots that were not true representations of the ocean floor.  Once you get an eye for it, you kill the noise quickly.  In addition, when Lieutenant Smith finds a notable rise in the ocean floor he will “designate as a sounding.”  Soundings are those black numbers on a nautical chart that tell you how deep the water is.

This line shows three colors, meaning three boats sent pings down to the ocean floor in this area.

If the line has dots that rise up in a natural way, the computer program recognizes that these pings didn’t go as far down as the others and makes a rise in the ocean floor indicated with the blue line.  It is the hydrographer’s job to review the computer processed data.  One of the differences between a map and a nautical chart is the high level of precision and review to ensure that a nautical chart is accurate.

This nautical chart went through many layers of analysis, processing and review before becoming published as a  nautical chart that can be used as a legal document.

NOAA has several interesting online resources with more information about the differences between charts and maps: http://oceanservice.noaa.gov/facts/chart_map.html .

Now let’s kill some noise on this calm May evening.

In this image of a shipwreck on the ocean floor most sonar pings reached the ocean floor or the shipwreck and bounced soundings back to the survey boat.  Look carefully, however, and you see white dots, representing pings that did not make it down to the ocean floor.  Many things can cause these false soundings.  In this case, I predict that the pings bounced back off of a school of fish.  Here, the surveyor kills the “noise” or white pings by circling them with the mouse on his computer. It wouldn’t be natural for the ocean floor or other feature to float unconnected to the ocean floor, and thus, we know those dots are “noise” and not measurements of the ocean floor.

Lieutenant Smith estimates that at least half of his survey time is spent in the plot room planning or processing data.  The window of time the team has in the field to collect data is limited by weather and other conditions, so they must work fast.  Afterward, they spend long, but rewarding hours analyzing the data they have collected to ensure its accuracy and to provide synthesized information to put into a nautical chart that is easy to use and dependable. Lieutenant Smith believes that in many scientific careers, as much time or more time is spent planning, processing and analyzing data than is spent collecting data.

 

Personal Log

As we post process our data, I too, begin post processing this amazing adventure.  I am hesitant to leave: I have learned so much in these two short weeks, I want to stay and keep learning.  But at NOAA we all have many duties, and my collateral, wait–my primary duty is to my students and so, I must return to the classroom.  I will leave many fond memories and a camera, floating somewhere in Driver Bay, behind me.  I will take with me all that I have learned about the complexity of the ocean planet we live on and share my thirst to know more back to the classroom where we can continue our work. I will miss the places I’ve seen and the people I met but look forward to the road or channel of discovery that awaits me and my students.

Science and Technology Log

As I explained in an earlier blog, all the scientist on the ship are here because of the Atlantic Marine Assessment Program for Protected Species, or AMAPPS for short. A multi-year project that has a large number of scientists from a variety of organizations whose main goal is “to document the relationship between the distribution and abundance of cetaceans, sea turtles and sea birds with the study area relative to their physical and biological environment.” So far I have shared with you some of the Oceanography and Marine Mammal Observing. Today I am going introduce you to our Marine Mammal Passive Acoustics team and some of their cool acoustic science. The two acoustic missions of the team are putting out 10 bottom mounted recorders called MARUs or Marine Autonomous Recording Units  and towing  behind the ship multiple underwater microphones called a Hydrophone Array to listen to the animals that are as much as 5 miles  away from the ship. The two different recording devices target two different main groups of whales. The MARU records low frequency sounds from a group of whales called Mysticetes or baleen whales: for example, Right Whales, and Humpback Whales. Once the the MARU has been programmed and deployed, it will stay out on the bottom of the ocean collecting sounds continuously for up to six months before the scientist will go retrieve the unit and get the data back.  The towed Hydrophone Array is recording higher frequency sounds made by Odontocetes or toothed whales like dolphins and sperm whales. The acoustic team listens to recordings and compares them with the visual teams sighting, with a goal of getting additional information about what kind and how many of the species are close to ship. Even though the acoustic team works while the visual team is working during the day, as long as there is deep enough water, they can also use their equipment in poor weather and at night.

Here are Chris and Genevieve preparing to deploy the MARU.

Personal Log

So while most adults were worrying about their taxes on April 15th, I was having fun decorating and deploying Drifter Buoys. Before I left for my trip Jerry Prezioso had sent me an email letting me know that two Drifter Buoys would be available for me to send out to sea during my time on the ship.  Drifter buoys allow scientists to collect observations on earth’s various ocean currents while also collecting data on sea surface temperature, atmospheric pressure, as well as winds and salinity. The scientists use this to help them with short term climate predictions, as well as climate research and monitoring. He explained that traditionally when teachers deploy the buoys, they will decorate them with items they bring from home and that we would be able to track where they go and the data they collect for 400 days! The day before I left, I had my students and my daughter’s class decorate a box of sticky labels for me to stick all over the two Drifter Buoys. I spent the morning of the 15th making a mess on the lab floor peeling and sticking all of the decorations onto each of the buoys. Around mid-day we were at our most south eastern point, which would be the best place to send the buoys out to sea.  Jerry and I worked together to throw the buoys off the side of the ship, as close together as we could get them. A few days later we heard from some folks at NOAA that the buoys were turned on and floating in the direction we wanted them too.

If you would like to track the buoys I deployed, visit the site below and follow the preceding directions.

Cetaceans Are Among Us!

Our Marine Mammal Observation (MMO) crew was in for a treat today. Just after lunch, we spot a pod of sperm whales. We spotted them off the port side, off the starboard side, and eventually off the bow of the Sette. We frequently see Humpback whales in Hawaii, but sperm whales often evade us. Sperm whales can dive down to extreme depths and they feed on squid. These same squid feed on the micronekton that we are observing during the cruise. Sperm whales are the largest of the toothed whales. Their enormous size is obvious when they slap the ocean with their giant tails. Another unique characteristic of the sperm whale is their blow hole, which sits to the left rather than on top of the head. This feature allows our MMO team to easily identify them.

Our MMO lead, Ali Bayless, determines that we should take the small boat out for a closer examination of the pod. Within minutes, the small boat and three scientists are in the water following the pod. We think that a calf (baby) is accompanying two of the adult whales. Throughout the next few hours, our small boat is in constant contact with our flying bridge, bridge, and acoustics team to determine the location of the whales. We keep a safe distance from all of the whales, but especially the calf. While on the small boat, MMO scientists also identify spotted and spinner dolphins. We are essentially surrounded by cetaceans. The small boat is just one of the many tools we use to determine what inhabits the ocean. We also use an EK60 sonar, our Remotely Operated Vehicle, our hydrophone, and sonar buoys.

Our acoustics lead, Adrienne Copeland, is especially excited about our sperm whale sightings. Adrienne is a graduate student in zoology at the University of Hawaii. She earned her Bachelor’s of Science in biology with a minor in math and a certificate in mathematical biology from Washington State University. She has served on the Sette four times and is currently serving her third stint as acoustics lead. This is a testament to her expertise and the respect she has earned within the field.

Adrienne Copeland monitors our acoustics station during our 2014 IEA cruise.

Adrienne Copeland studies the foraging behavior of deep diving odontocetes (toothed whales). She shares that some deep diving odontocetes have been known to dive more than 1000 meters. Short finned pilot whales have been observed diving 600-800 meters during the day. During night dives we know they forage at shallower depths on squid and fish. How do we know how deep these mammals dive? Tags placed on these mammals send depth data to scientists. How do we know what marine mammals eat? Scientists are able to examine the stomach contents of mammals who are stranded. Interestingly, scientists know that sperm whales feed on histioteuthis (a type of squid) in the Gulf of Mexico. A 2014 IEA trawl operation brought in one of these squid, which the sperm whales may be targeting for food.

Notice the distinct blue and gray lines toward the top of the screen. These are the think layers of micronekton that migrated up at sunset. The number at the top of the screen expresses the depth to the sea floor.
Notice the distinct blue and gray lines toward the top of the screen. These are the thick layers of micronekton that migrated up at sunset. The number at the top of the screen expresses the depth to the sea floor.

Examine the acoustics screen to the left. Can you identify the gray and blue lines toward the top of the screen? These scattering layers of micronekton ascend and descend depending on the sun. Adrienne is interested in learning how these scattering layers change during whale foraging. Our EK60, Remotely Operated Vehicle, and highly prescribed trawling all allow us to gain a better understanding of the contents of the scattering layers. A greater understanding of whale and micronekton behavior has the potential to lead to more effective conservation practices. All marine mammals are currently protected under the Marine Mammal Protection Act. Sperm Whales are protected under the Endangered Species Act.

Interesting fact from Adrienne: Historical scientists could indeed see the scattering layers on their sonar, but they thought the layers were the ocean floor. Now we know they represent the layers of micronekton, but old habits die hard, so the science community sometimes refers to them as false bottoms.

Live Feed at 543 Meters!

The ROV prior to deployment.

Our Remotely Operated Vehicle (ROV) deployment is a success! We deploy the ROV thanks to an effective team of crew members, scientists, and NOAA Corps officers working together. ROV deployment takes place on the port side of the ship. We take our ROV down to approximately 543 meters. We are able to survey with the ROV for a solid five hours. A plethora of team members stop by the eLab to “ooh” and “ahh” over the live feed from the ROV. Excitingly, the ROV is deployed prior to the vertical migration of the micronekton and during the early stages of the ascent. The timing is impeccable because our acoustics team is very curious to know which animals contribute to the thick blue and gray lines on our acoustics screens during the migration. In the ROV live feed, the micronekton are certainly visible. However, because the animals are so small, they almost look like snow falling in front of the ROV camera. Periodically, we can identify squid, larger fish, and jellies.

Mini hyperbaric chambers can be used to save fish who are brought to the surface from deep depths. These chambers are often used to assist humans who scuba dive at depths too deep for humans or who do not effectively depressurize when returning to the surface after SCUBA diving. The pressure of the deep water can be life threatening for humans. Too much pressure or too little pressure in the water can be life threatening for marine life, too. Marine life collector, Kevin Lewand, constructed a marine life hyperbaric chamber aboard the Sette. He learned this skill from his mentor. Be sure to say Aloha to him when you visit the Monterey Bay Aquarium in Monterey, California.

There is never a dull moment on the ship. Tonight we have ROV operations, squid jigging, acoustics monitoring, and a CTD deployment. We of course can’t forget the fact that our bridge officers are constantly ensuring we are en route to our next location. Tonight’s science operations will most likely end around 05:00 (tomorrow). Crew members work 24/7 and are usually willing to share their expertise or a good story. If they are busy completing a task, they always offer to chat at another time. I find that the more I learn about the Sette, the more I yearn to know. The end of the cruise is just two days away. I am surprised by how quickly my time aboard the ship has passed. I look forward to sharing my new knowledge and amazing experiences with my students and colleagues. I have a strong feeling that my students will want to ask as many questions as I have asked the Sette crew. Aloha and mahalo to the Sette.

Mt. Mansfield

Greetings from Vermont, the Green Mountain State.  My name is Liz Harrington and I live in Cambridge, VT.  Cambridge is a small town at the foot of Mount Mansfield, our state’s tallest mountain with a peak of 4395 feet (1340 meters).  Ok, the Green Mountains aren’t as big as the Rockies, but they provide us with recreational opportunities, wildlife habitat and scenic beauty. We love them.   I am a science teacher at Essex High School in Essex Junction, VT.   Currently I am teaching Earth Science and Forensics.  I also help teach a Belize Field Study class.

Essex High School

My teaching career has worked out perfectly for me.  After graduating from UConn with an Animal Science degree, I married and raised four wonderful children.  As they grew, I returned to school to earn my teacher certification in secondary science education.  When my youngest went to kindergarten, I began teaching part time at Essex High School. I had the best of both worlds.  It was during these first few years of teaching that I heard about NOAA’s Teacher at Sea (TAS) program.  I immediately knew I wanted to be involved in the program, but it required being a full time teacher.  A few years ago my teaching became full time.  I applied to TAS, was accepted and will be aboard the NOAA ship Oregon II this summer.  I’m thrilled!

I have always had a close connection with the ocean as I grew up on the shore of southeastern Connecticut.  I spent many hours swimming off the docks or climbing out onto the rocks to crab.  I also did lots of fishing and boating, but I took the ocean for granted.  I didn’t realize how much I would miss it when I moved away.  I am fortunate that my parents still live at the shore and my children have had the opportunity to create their own ocean experiences.  And it is always an amazing sight to see their Vermont friends encounter the sounds, smells, textures and activities of the ocean for the first time!

Belize
Belize class trip

The Belize Field Study class has a culminating ten day trip to Belize.  The first four days are spent exploring the coral reefs and learning more about issues concerning the reef.  Some of the students snorkel and some of them scuba dive, but either way they are able to explore the underwater world.  Here, again, I am able to bring students to the ocean and I love to see their excitement, interest and concern.  The ocean’s fate will soon be in their generation’s hands and these personal connections make a difference.

Science and Technology Log:

The Oregon II is a NOAA ship which supports the programs of the National Marine Fisheries Service (NMFS).  The ship conducts studies at various times of the year on organisms such as ground fish, sharks, plankton, reef fish and marine mammals.  I will be joining a Shark/Red Snapper Bottom Longline Survey.  We will be sailing from Mayport, Florida and spending two weeks in the Gulf of Mexico.  The trip will end in the home port of Pascagoula, Mississippi. I am honored at having been chosen as a Teacher at Sea.  I can’t wait to be working with the scientists and crew aboard the Oregon II and participating in real scientific research.  I’m also looking forward to sharing my experiences with my students and bringing new topics into the classroom.  Through this trip I’m hoping they can make connections to the ocean as well.  I’ll be sharing my adventures a few times a week with this blog.  I hope you will follow along.

July 8-25, 2013 

Mission: Hydrographic Survey
Geographical Area of Cruise: Shumagin Islands, Alaska
Date: July 19, 2013

Current Location: 54° 49.684 N, 159° 46.604 W

Weather Data from the Bridge: Foggy and overcast, wind 21 knots, air temperature: 11.5° C

Science and Technology Log:

As the fog horn sounds every two minutes and we sail solitary through the ocean, we are now in full swing surveying the Shumagin Islands, between and around Nagai, Bird, and Chernabura Islands. Unlike the old-time surveyors who used lead lines (lead weight attached to a long string), we are using a multibeam sonar system, which enables us to gather a large quantity of very accurate data in a more efficient and timely fashion.

3D sea floor
Processed sonar data showing 3D image of the sea floor.

Sonar, (SOund Navigation And Ranging) uses the principle of sound wave reflection to detect objects in the water. Just as our eyes see the reflection of visible light off of the objects around us to create a visual image, when a sound wave hits something, it reflects off that “thing” and returns to its starting point (the receiver). We can measure the time it takes for a pulse to travel from the Sonar device below the boat to the ocean floor and then back to the receiver on the boat. Using a simple distance=speed * time equation, we can get the water depth at the spot where each beam is reflected.

The skiff that we use for the shoreline activities discussed in the last post has a single-beam sonar system that directs a pulse straight down beneath the hull to get a rough depth estimate. However, for our hydrographic work on the ship and launches, we use a multibeam system that sends 512 sound pulses simultaneously towards the sea floor over a 120° angle. When many sound waves or “beams” are emitted at the same time (called a pulse) in a fan like pattern (called a swath), the reflected information creates a “sound picture” of the objects or surface within that swath range. The actual width of this swath varies with the depth, but with 512 beams per pulse, and sending out between 5-30 pulses every second, we acquire a lot of data. If you piece together many swaths worth of data you get a continuous topographical or physical map of the ocean floor, and thus the depth of the water. For more information about the specific sonar system used aboard the Rainier and its launches, check out the ship page or the NOAA page about their hydrography work.

In order to understand the complexities of sonar, it is important to understand the properties of sound. Sound is a pressure wave that travels when molecules collide with each other. We know that sound can travel in air, because we experience this every day when we talk to each other, but it can also travel in liquids and solids (which whales rely on to communicate). As a general rule, sound travels much faster in liquids and solids than in air because the molecules in liquids and solids are closer together and therefore collide more often, passing on the vibration at a faster rate. (The average speed of sound in air is about 343 meters every second, whereas the approximate speed of sound in water we have been measuring is around 1475 meters every second). Within a non-uniform liquid, like saltwater, the speed of sound varies depending on the various properties of the saltwater at the survey site. These properties include water temperature, dissolved impurities (i.e. salts, measured by salinity), and pressure. An increase in any of these properties leads to an increase in the speed of sound, and since we’re using the equation distance = speed * time equation, it is crucial to consistently measure them when seeking depth measurements.

CTD Data
Data from CTD showing temperature vs. sound speed from one data set. Notice how the temperature and sound speed seem correlated.

To measure these properties, a device called a CTD (Conductivity-Temperature-Depth) is used. Conductivity in this acronym refers to the free flowing ions in salt water (Na and Cl, for example), which are conductive and the concentration of these ions determines the salinity of the water. The CTD measures these three properties (Conductivity, Temperature and Depth) so the speed of sound in the water can be calculated at every point in the water column

To use the CTD, lovely humans like Avery and I will drop it into the water (it is attached to a winch system) at the area where we are surveying and as it travels to the sea floor, it takes a profile of the three saltwater properties mentioned before. Back in the computer lab, software takes this profile data and calculates the sound velocity or speed of sound through the water in that region.  As a crosscheck, we compare our profile data and sound velocity figures obtained at the site to historical measured limits for each property. If our measurements fall significantly outside of these historical values, we might try casting again or switch to a different CTD. However, because we are surveying in such a remote area, in some cases, data outside historical limits is acceptable.

CTD graphs
Graph of our sound speed vs. depth data showing comparison to historical data.

Given that we are trying to determine the water depth to within centimeters, variations in the sound speed profile can cause substantial enough errors that we try to take a “cast” or CTD reading in each small area that we are gathering data. The software the survey team uses is able to correct automatically for the sound velocity variations by using the data from the CTD. This means that the depth profile created by the sonar systems is adjusted based on the actual sound velocities (from the CTD data) rather than the surface sound speed. We are also able to account for speed changes that would cause refraction, or a bending of the beam as it travels, which would otherwise provide inaccurate data about the location of the sea floor.

Avery lowers the CTD into the water for a "cast". The CTD needs to sit in the water for a few minutes to acclimate before being lowered for a profile.

You can’t go to Alaska without fishing its waters, rich with a variety of delectable fish species.  So I decided to get my Alaskan recreation fishing license and try my hand at it on the fantail (stern) of the Rainier, while we were anchored in Bird Island cove. Carl VerPlanck, an experienced fisherman with arms like Arnold Schwarzenegger, had coached me on the best jigging techniques for catching a halibut and with my eyes (and mind) on the prize I followed his instructions diligently.  It paid off as I landed several fish my first night on the fantail, with one halibut being a true keeper. John Kidd, NOAA Corps. Officer, gaffed my meaty fish over the steep rail of the Rainier and hauled it aboard.  He was impressed with my catch (and hidden fishing talent), stating “This is the biggest fish caught so far this season.” Woohoo! Most impressive was the amount of meat the fish yielded (4 large filets) which I proudly donated to the kitchen and John. (Three big filets to the kitchen and one filet to John for his camaraderie, the use of his high-tech rod set-up and filleting skills). The following night, we all ate delicious baked Pacific Halibut filets, coated in a creamy Caesar glaze, prepared by chef-extraordinaire, Kathy. It’s pretty cool that I got to feed the ship!!

This was my first time catching a halibut and after close examination (and dissection) of this large, rather bizarre looking flatfish I became very intrigued and had several questions: How and why do the eyes migrate to one side?  How do you tell the age of a halibut? What does the word “halibut” mean?

Like any good scientist, I proceeded to find the answers to these questions, and in doing so, learned many more interesting tidbits about Halibut. (The other species of halibut is the Atlantic Halibut which is very similar to the Pacific Halibut and is named as such for the ocean it occupies.)

So lets start with the name “halibut.” It’s origin is Latin (hali=haly=holy, but=butt=flat fish) and literally translates to “holy flat fish” because it was popular on Catholic holy days. Now what’s with the eye migration and why are both eyes on the same side? Well to understand this question thoroughly we must look at the conditions under which the halibut is born. Female halibut are sexually mature at age 12, spawning from November to March in deep water (300-1500 feet). Depending on their size, females release several thousand to several million eggs which are fertilized externally by the males. After the eggs are fertilized by the males, they become buoyant and start to float up the water column, hatching into free floating larva at about 16 days.  As the larva mature, they continue to rise to the surface. At this larval stage they are upright, like any other “regular” fish, with one eye on each side of their head. This eye placement makes sense, considering they are in the open ocean with water on all sides of them.  When at or near the surface, the larvae drift towards shore by ocean currents. As they get closer to shore and at about 1 inch in length, they undergo a very unique metamorphosis in which the left eye moves over the snout to the right side of the head. At the same time their left side fades in color eventually becoming white and their right side becomes a mottled olive-brown color. By 6 months, they are ready to settle to the bottom in near shore areas, hiding under the silt and sand, with just eyes exposed. Their mottled side will be face up, blending into their surrounds and their white side will face down, creating a “countershading” coloration, which helps keep them hidden from predators.

From halibut larvae to adult halibut. Notice the migration of the left eye to the right side and the pigmentation at the last stage.
Halibut development: from halibut larvae to adult halibut. Notice the migration of the left eye to the right side and the pigmentation at the last stage.

The Pacific Halibut I caught was by no means a monster or “barn door” as the huge ones are called. But it also was not a “chicken”, slang for a small halibut. Female halibut can reach lengths of 8 feet and a weight of 500+ pounds. Males rarely exceed 100 pounds.  Halibut are generally not picky eaters and will pretty much eat anything that lives in the ocean.  Carl joked that a halibut would even eat an old shoe dangling from a fishing pole.

I was surprised to learn that halibut can live as long as 55 years.  Scientists can accurately age a halibut by counting the rings in their ear bone or “otolith”, similar to dating a tree using its annual growth rings. So next time you catch a halibut and plan on keeping it, try to find the ear bone, grab a microscope and age the fish. If that fails, don’t forget to cut the cheeks out of the halibut (along with the 4 regular meaty fillets), for I am told that is the best part to eat. 🙂

Fun factoid: Sonar works a lot like the echo sounding of a bat, and its development was partially prompted by the Titanic disaster.

Hello from aboard NOAA ship  Pisces.  We are gearing up to set sail so I will take this opportunity to introduce myself before we get underway!  My name is Jennifer Petro and I am an 8th grade Science Teacher at Everitt Middle School in Panama City , Florida.  I am particularly excited about this mission as I am working alongside scientists from the NOAA Southeast Fisheries Science Lab located on Panama City Beach.  I will also be working with scientist from Harbor Branch Oceanographic Institute as well as Woods Hole Oceanographic Institute. The focus of this mission is to survey fish and invertebrate populations in Marine Protected Areas (MPAs) from Florida to North Carolina.  We will also be doing mapping of new areas to determine future MPAs.

The scientist have been busy setting up and calibrating their equipment.  We will be using an ROV, Remotely Operated (underwater) Vehicle, to view the MPAs.  There are several cameras attached to the ROV which the scientist will use to identify and count species.  There are many feet of wire and cables being set up in the dry lab.

Currently we are still at port and are scheduled to set sail in a few hours.  The Pisces is a rather comfortable vessel.  We arrived yesterday afternoon so I already have one night’s sleep on board under my belt.  I imagine things will change when we are out at sea, but for the moment she is gently swaying in port.  I share a room with one of the scientists and we in turn share a bathroom.  Pretty great so far! The Pisces is currently moored at NAS in Mayport , FL and is dwarfed in size to all of the naval vessels that surround her!

The Pisces is on its way to port, having had to suspend operations in wake of the bad weather that has since become Tropical Storm Andrea. We were supposed to go into Mayport Naval Base, right outside of Jacksonville, FL, but due to the storm we have been redirected to Port Canaveral.

Ocean
It’s been pretty rough out there! (Picture courtesy Ariane Frappier)

Despite all of this, we made the best of a bad situation. Even though we couldn’t do fishing or camera drops yesterday, we did still manage to get some data. We spent as much time as we could mapping the seafloor before we had to dodge the storm, and we took the time in the morning to do an XBT, an Expendable Bathythermograph.

You can use an XBT to get a temperature and depth reading for the water without having to actually stop the ship. A tube with a probe on it is attached to a launcher and is fired into the water. The probe has copper wire attached to it to send the data back to the ship.

So…you drop the probe, you get the readings, and at least you get some data even if you can’t stop the ship to send more delicate equipment down.

XBT

Other than that, the past couple of days have been all about cleanup and dodging the storm. To a certain extent that makes the scientific posts a little quieter than usual, but it’s been a very interesting experience watching everyone work together to make sure that the scientists could get as much work done as possible without endangering the ship or its crew.

We didn’t get to do everything that we wanted to do on this leg of the trip, unfortunately. But we still got a lot accomplished, and I feel like it was just as interesting to see how everyone was able to react to the weather and still get their job done.

Personal Log

Whew! I didn’t imagine when I got on the Pisces in Tampa that I’d spend the last bit of the trip dodging the first named Tropical Storm of the Atlantic hurricane season. But I definitely have a greater appreciation that, with science as in all things, sometimes life does not go quite to plan.

If all goes to schedule, I will be leaving the Pisces tonight, for our detour into Port Canaveral. We had to stop working a day early, and we’ll end up arriving a day early and into a different port. My last day has mostly been spent trying to rearrange for my travel home from a new city and with assisting the science crew in cleaning up the lab spaces.

All data collection requires a certain amount of flexibility. I knew that already – social science data is notoriously difficult to collect – but the problems that I face in my work are quite different from these. When international relations scholars have trouble with data, it’s usually because of things like difficulties in getting governments and/or people to tell the truth, etc. But sometimes, as now, it’s because conditions make it unsafe to collect the data. We can’t send people into shooting wars to count casualties, and we can’t send scientists into a hurricane to count fish.

Science is a method, not a subject, and the scientific method is one wherein we all simply do our best with what we have. Science has been so profoundly influential because of the simple power of this process, testing over and over what we think to be true, so that we can learn if we are wrong. It’s true if you study fish, if you study policy, or if you study anything in between.

There are many things we’ve discovered about our oceans, and the fish and other creatures that inhabit them. But there are still many more things to learn. I’m glad that we have scientists like the ones I met on the Pisces out looking for our fish, and glad that NOAA, in conjunction with states and other government agencies like the Coast Guard, are looking out for our oceans.

My thanks go out to the entire crew of the Pisces, and the great people at the Teacher at Sea program, for letting me be a part of the process.

Science and Technology Log

So I’ve known for about two months or so that I was going to be taking part in one leg of an ongoing reef fishery survey. I even had an idea that it involved surveying fish that lived on reefs. But after our first full day at sea, and many hours of helping take part in the scientific work, I now begin to understand how exactly one surveys reef fish.

There’s a couple of different things that the scientific crew is doing to observe and understand the reef fish population. First, there is an ongoing video recording process throughout the day, from just after sunrise to just before sunset. For this, the ship and scientific crew lower a large, 600 pound camera array off of the starboard side of the ship. The cameras will go and sit on the sea floor and record all the fish that pass in front of it, for a total recording time of 25 minutes. After this time has passed, plus a little extra time, the cameras are pulled back up, the recordings are downloaded, we move to a different spot and the process begins again.

Underwater Camera Array

The video is reviewed the next day. Since this is our first day at sea, I didn’t get much of a chance to see any reef fishery footage, though I’m told that’s on the agenda for tomorrow. What I spent most of my time doing was helping out with another part of the survey process, something called the bandit reels. They’re used for good old-fashioned hook and line fishing.

Bandit Reel
It looks like a nice day to go fishing, huh?

There are three bandit reels on the Pisces, and each one can hold 10 fishing hooks. Each reel has different sized hooks, and the hook sizes are changed every drop. The line has a weight at the bottom to bring the hooks down to the sea floor, which have been baited with mackerel bits. After five minutes, the line is reeled back in, and you have fish…or you don’t.

My first drop, which had the biggest hooks, had a whole bunch of nothing. As did everyone else’s, though, so it wasn’t a testament to my poor fishing skills.

The second drop, however, was luckier.

Eel on hook.
I caught a moray eel!

A spotted moray eel! I was excited, anyway. But morays aren’t one of the fish that we’re looking for out here, so it wasn’t a particularly useful catch.

Our third drop was the most successful. Our bandit reel hauled in seven fish, one of whom got away (the biggest one, of course, one the size of a killer whale…yeah, just kidding!). The other six were brought into the wet lab, where they joined the other fish caught on that drop and would be measured and dissected.

Fish on a measuring board.
We caught a big one!

The fish are measured three different ways. The first, by total length, examines exactly that, the total length of the fish from the nose all the way to the tip of the tail. The second measure goes from the nose to the fork in the tail, so it’s a shorter distance. The third, standard length, goes from the nose to just before the tail fin, where the fish’s vertebrae end, and is the shortest of all. They’re also weighed at this time as well.

After that, we start cutting into the fish. Two things are of interest here: the ear bone and the sex organs. The ear bones are removed from each fish, because they can be tested to determine the age of the fish. The sex organs will reveal gender, obviously, but also are examined to see how fertile each specimen is. We don’t do this kind of analysis on the ship, however. The ear bones and sex organs are sent back to the NOAA lab in Panama City, Florida, where they will conduct all those tests.

Personal Log

The best part of my first day at sea was definitely the ship safety drills.

Wait, what?

No, seriously.  The absolute highlight of this one was my chance to try on what’s known as the Gumby suit. The Gumby suit is a nickname for a immersion survival suit – if we have to abandon ship and float around in the water, the suit will protect us from the elements. Now, we’re down here in the Gulf of Mexico, so that seems a little crazy, but think about how you’d feel if you were stuck in the water for hours on end. In really cold waters, that suit may be the difference between life and death.

The drills are important, and they’re mandated for a reason. In an emergency, all of this stuff can save lives.

Why do I like the drills so much? We’re required to have safety drills by law, and so as someone who studies and teaches international law, I always enjoy taking part in these things. It’s a chance to see the stuff in action that I talk about in class. And that’s kind of what this program is all about – the chance to experience things firsthand as opposed to just having to read about them.

Gumby suit
I guess you kind of have to take my word for it, but that’s me in there.

Did You Know?

You’re supposed to be able to put on a Gumby suit in under a minute. They wouldn’t do much good if they took too long to put on.

Log: Petersburg: Completing the journey

No Teacher at Sea journey would be complete without immersing oneself in the people whose lives are dependent on that sea. Such an opportunity presented itself as we made port at Petersburg, the town that was “built on fish” (Little Norway Festival Pageant). We pulled into Petersburg during the annual “Little Norway” cultural festival held over Syttende Mai weekend celebrating the signing of Norway’s constitution. Since 1958, Petersburg has celebrated this powerful conjunction of Norwegian heritage and the vital role of fish and the fishing industry.

Like many small towns, the Little Norway festival gathers the community together for a parade, softball tournament, dunk stand, food booths, walk/run, and pancake breakfast. Unlike other towns, Little Norway is graced with music from the Pickled Herring Band, a herring toss (think water balloon toss with fish), fish barbecue, and wandering Vikings willing to raid any party along their way. The closing song at the festival pageant seems to capture the spirit of Petersburg.

Today’s Petersburg brings together the native Alaskan traditions with the heavy Norwegian influence. A pair of towering totem poles on one end of town capture the history and contributions of the Tlingit hunters and fishermen that roamed these parts since over 2000 years ago. Coming into Petersburg we encountered several icebergs calved from the nearby LeConte Glacier. It was the presence of this clean source of ice that led the Norwegian Pioneer, Peter Buschmann to recognize the potential for the use of this ready supply of ice to pack fish and in 1897 started the Icy Strait Packing Company. He went on to add a sawmill and dock, and the town of Petersburg was launched. By 1920, Petersburg had become a town of 600 people and growing – majority of which shared Peter’s Scandinavian descent.

Fishing is and has always been a constant presence throughout Petersburg’s history. At one end of town lies the Fisherman’s Memorial Park committed to the memory of those lives “that have been lost at sea and/or spent much of their lives working directly in the fishing industry” (Plaque at the base of the statue of the fisherman). On the other end is Eagle’s Roost Park highlighting the “outlook point for wives awaiting their husbands return from fishing” (plaque at Eagle’s Roost Park). Centered within are the present day canneries and businesses that keep this unique community vital. A plaque honoring a Petersburg pioneer states, “When he taught us to fish; he taught us to appreciate the rewards of patience. When he taught us to row; he taught us the power of perseverance and hard work.” Seems these words have served this community well.

One gets a picture of the culture of a place by strolling through its shops. Unlike Ketchikan with its cruise line stocked gift shops, the merchants of Petersburg carve their own personal niches into the culture of the community. I have always enjoyed strolling through hardware and grocery stores. They serve as reflections of the life and values of the surrounding community. The Petersburg True Value hardware store shelves are stocked with the necessities of life for this fishing community. Along with nails, screws, and Weber grills you might find in any hardware store, here are rows and rows of waterproof gloves, bib overalls, jackets, flotation gear, rope of all kinds, snaps, and chains that are needed for the boats on their fishing journeys at sea. Along with the groceries one might expect, the Petersburg IGA stocks supplies of hardy Carhartt mariner clothing, washing machines, recliners, and iPhones. Each gift shop in town is unique, serving as markets for locally crafted goods by area artisans. There isn’t a place in Petersburg for the nondescript big box retailers of larger cities. These merchants stock all the supplies necessary to keep the pulse of the lifeblood of this community going. In so doing, they keep alive what makes this community unique. Not unlike the life I experienced on board the Rainier, Petersburg is an island community that has learned to rely on itself for the safety and well-being of all its members.

The festival comes to a conclusion with the annual fish barbecue held at Sandy Beach park. The event centers on all the grilled salmon, black cod and rockfish you can eat – hot off the wood fired barbecue pit. To a Minnesotan so far from the sea, this much seafood all in one spot grilled to perfection was truly a great way to being to a close my time in Petersburg.

Tomorrow I fly out on what I was told was the milk run, leaving Petersburg for a 34 mile flight to Wrangell, then 83 miles to Ketchikan, on to Seattle, then finally home to Minneapolis/Saint Paul. I leave behind the life and work of the Rainier, the majestic views of the Alaskan landscape, and a glimpse into the quaint Norwegian community that was built on fish. I take with me the memories and stories of my little slice of life at sea, and all insight gained from the deep cognitive stretching obtained at the hands of the mariners, survey technicians, and NOAA Corps on board the Rainier. A special thank you to NOAA and the members of the Rainier community for making this powerful Teacher at Sea adventure possible.

Addendum: Monday, May 20

I met Rob Thomason, the Petersburg school superintendent, at the fish barbecue and was invited to the school for a tour and visit. This morning I took him up on his invitation and was treated to a two-hour tour of Stedman Elementary, Mitkof Middle, and Petersburg High School. The Petersburg schools’ match the charm and close knit community atmosphere of the town itself. During that time I was witness to many of the things that make this school special. Earlier that morning, a high school class had boarded a boat for a trip to a nearby glacier to conduct field studies. Between the schools was a boat the high school shop class had manufactured. Students in an elementary class were making fish prints – painting a fish and pressing a white t-shirt onto its surface. I naively made the comment, “That looks like a real fish.” He smiled and nodded. In the back schoolyard was the construction of a new greenhouse for the schoolyard gardens. We stopped in a culinary arts class and were treated to a plate of freshly made sushi rolls. Both buses are parked in a single garage. Class sizes are in the upper teens/lower 20s. Everywhere I looked, students were engaged in their learning. The taxi driver bringing me to the airport had just picked his kids up at the school. Without hesitation, he shared his opinion that the Petersburg schools were the best in the country. With district NCLB passing rates in the high 80s, perhaps Petersburg Public Schools are on to something – low class sizes, authentic learning experiences, strong community support, stable faculty and staff, and a positive, nurturing learning environment committed to all students. Thanks for the visit.

Personal Log

For as long as I can remember, I have loved maps. A good map is an invitation to explore, to let the mind wander in distant lands, among unfamiliar environs, and into new challenges, but always with the advice of the explorers who walked there earlier. Imagine being the first person to cross a dense bit of jungle or a vast glacier, to find an underground passageway of ancient caves, or to walk on the surface of some planet. Certainly, you or other people might have created speculative pictures in your head before your journey, hypotheses about what you might find. But those hypotheses must be tested, verified, investigated. The explorer bravely takes the advice of others, the creative ideas that grow from his own previous experiences and imaginings, and whatever other tools fit into his kit, and he walks forward.

That is what we humans are. Explorers.

Even young children are scientists. Starting from very little background knowledge, they do that most human of activities: They wonder. Uninhibited by the social structures of the adult world, they spend nearly all of their waking moments drawing new maps in their heads. Maps of the paths of beetles crossing the yard, maps of the grocery store aisles, maps of best hiding places on the playground or in the house… but not only geographic maps. They also “draw maps” of how to talk Mom into an extra snack, how to fill the bathtub with bubbly water, and how to put on a shirt.

When Euclid wrote Book 1 of his Elements, he laid down a road map of proofs so that others could confidently follow him to the Pythagorean Theorem. When Leonardo da Vinci and the Wright Brothers made drawings of their flying machines, they were mapping the paths that they had trod toward liberating humans from the clutches of Earth’s gravity. And when Grandpa wrote the recipe for his excellent gumbo, he, too, was a cartographer, taking notes about how he had done the work so that others might learn from it and, maybe, expand it into something more meaningful and delicious in their own lives.

The land and surrounding waters of Alaska have captivated humans for many ages. The majesty of the advancing and receding glaciers as they slowly carve valleys amid the mountains, the freedom of the soaring flights of eagles as they look down upon the rarely-visible orcas and belugas, the mystic palette of icy blues and whites against the vernal greens and floral splashes… People travel to, through, along, and across Alaska for commerce, for sightseeing, for escape, and for investigation, and the maps of those who have gone before them make those passages easier and more interesting, both by providing guideposts and by leaving other details to be explored by the new travelers with their own curiosities and motivations.

When I join CDR Rick Brennan (who is both the Commanding Officer and the Chief Science Officer of the ship), Executive Officer Holly Jablonski, and the rest of the crew of NOAA Ship Rainier in a few weeks, I will be learning how skilled scientists continue the grand tradition of mapmaking, using modern equipment to plumb the depths and chart the coasts from Juneau to Kodiak, updating the notes made by previous explorers so that the next travelers will have the confidence of our data before they add their own interesting pieces to their own maps. By participating actively in the expedition, I will be mapping new territory for my students and myself, too, as I gain first-hand evidence of how scientists in the field conduct the business of their science. Remember that more than two-thirds of Earth’s surface is covered with water, and we have more than 100 miles of atmosphere above our heads, and yet we’ve barely begun to explore those regions of our own home world. That makes the work and leadership of the National Oceanic and Atmospheric Administration even more important because they are pioneers at this early stage in human exploration of those parts of our planet.

Don’t you wonder what it might have been like to hang out with Galileo as he peered through his telescope, to sit next to Beethoven as he composed and edited a symphony, or even to watch the patient musings of Mendel as he gardened peas season after season? I do. It’s difficult to remember what it felt like to be a young explorer, unburdened by almost any preconceptions. But exploration is always available if we are willing to open our eyes and minds, and to get our hands dirty while investigating our own surroundings.

And when I return to my 8th-grade classroom in tiny land-locked Lake Butler, Florida, at Lake Butler Middle School,  I’ll be able to share my own first-hand experiences and explorations aboard Rainier. I look forward to feeling the excitement bubble from inside me to capture the curiosities of my kids, as I act out the launching of depth-finding devices, display real data from my cruise, and share stories, notes, pictures, and videos to help them see and smell and hear what I witnessed. I look forward to my students’ questions after I return as much as I am excited about my own questions now. And I know that I won’t be able to answer all of those questions, but that’s the beauty of exploration: The students’ own wonderings will lead them to continue the explorations themselves, to enhance the maps with new notes, new details, and new points of interest.

Teachers always are motivating their students to dig in, to investigate, to think for themselves and take chances with new and creative ideas. Of course, my students read to learn what others before them have discovered, but they learn in other and sometimes more meaningful ways by designing and building their own rockets, by lifting heavy weights with different sets of pulleys, and by constructing legitimate scale models of their home solar system. As a teacher, I have great influence over the young people in my care, and so I also must explore so that my students can trust my insistence that learning by active engagement is necessary and a real commitment for life-long learning. By leaving the comfort of my home to conduct hydrographic surveys along the coast of Alaska with the crew of Rainier, I hope to model that commitment.

A last note: There’s something very poetic and temporal about starting my cruise at Juneau and ending it at Kodiak. Juneau is the capital of the state of Alaska, and Kodiak was the regional capital when Alaska was Russian territory. Moreover, regardless of the political boundaries, people of different tribes and nations have lived in the region since long before either country formally existed. Maybe what I’m saying is that the maps always will be re-drawn based on what people want to see in those maps. In some ways, people are just like people always have been, and in other ways they change. So does the land, so does the sea. And so I end this first blog where I started it, by respecting the role of the mapmaker as a trailblazer, a note-taker, a guide, and an explorer.

Keep exploring, my friends. And follow my blog here to travel with me and see where my explorations go next. Thanks for reading.

Science and Technology Log: The Small Boats

Yesterday the ship captured most of the ocean basin using its multibeam sonar equipment located on the bottom of the ship. Today we set out in smaller launches that could take us to the sections of the ocean the big ship couldn’t. Three teams were deployed, each containing a coxswain (person who has the skills to handle the boat), senior hydrology technician (in charge of the survey work to be done), and several others to help – one boat of which was gracious enough to take along a rookie “Teacher of the Sea” to experience first hand the work involved.

We all met on the fantail (rear deck) of the ship at 6:30 AM to go over the work that lays ahead. From there the launches were lowered off the ship, we entered, were released, and off we went. While still in the early morning low tide we examined the shoreline to verify the existence or non-existence of rocks in question from the last survey. We conducted our surveys throughout the rest of the day in areas not able to be accessed by the larger ship. Each launch is also equipped with multibeam sonar units on the bottom of the boat (image) and a plotting computer on board. As with the ship, the computer measures and controls for location (GPS); heave, pitch, and roll; and the temperature and salinity of the water column below our boat.

The work is similar, yet has a different feel. Unlike the automated features on the ship, a control panel allows the surveyor to hand tune variables that will help assure the best measurements. We can control the strength of the sound waves leaving the boat, the frequency of pings, wave length, and the degree of sweep that will be collected. Doing so allows us to maintain sufficient strength to capture tbe bottom, but not so overpowering that we lose the finer details such as the makeup of the bottom. Each boat sets a path back and forth at a speed of 7-10 knots in the sections assigned by the FOO (Field Operations Officer). This is repeated until each section is covered. This takes a concerted and collaborative effort between the coxswain and technicians. When surveying from the ship, the Moving Vessel Profiler’s fish can be cast by the push of a button at the computer in the Plotting lab. Not so on the launch. After bringing the boat to a stop, we lift over the CTD (conductivity, temperature, depth) instrument. We allow it to drop to the bottom before we turn on the winch to reel it back in. It is lifted out and attached to a cable connected to the computer where the data is downloaded.

Before we get back to the ship, we download the day’s data to an external hard drive and hand it off to another crew that begins the job of cleaning the data to be pieced together with all the other sections of data. We end with one complete picture of the project area.

Life at sea

There are 46 people living and working on board the ship. The launches go out with a smaller group of 4. Spending all day on a small boat with three other people necessitates attention to clear communication channels. The waves continually keep the boat in motion providing a challenge to manipulate the mouse and detail on the computer screen. In between there are many moments of quiet allowing for conversation and banter. It is in those moments you get to know one another better and forge strong relationships. This close community is evident among the crew on board. Such is the allure of sea life.

Sunny days

In anticipation of a trip to SE Alaska, I did a bit of research on what kind of weather to expect. Ketchikan is in a rain forest and noted for being the rainiest city in the United States with an average rainfall of 160 inches a year.  Since my arrival, I have enjoyed sunshine and calm seas. People have assured me how unusual this is and to expect a change. The forecast for tomorrow suggest the change will arrive. Seems to experience life at sea without a bout of inclement weather would not allow full appreciation of the grandeur we have had. I will take them both expecting there will be equal beauty in the rain and clouds.

I continue to be amazed at the majesty of the landscape.

Science and Technology Log: Mapping the Ocean

The work we do on board the Rainier is all centered on the task of gathering data of the ocean bottom – shoreline to shoreline. These data are used to update the nautical charts (maps) used by sailors. The project we have been working on is a section of Behm Canal in SE Alaska.

Nautical map of Behm Canal
Nautical map of Behm Canal

Hydrographic data on parts of this stretch of water haven’t been updated for over 100 years. The tools and methods utilized have changed significantly during that time. Hydrographers of 1900 lowered a rope tied to a lead weight to the ocean bottom. Measurements were taken on the length of rope. The area we were surveying ranges from 150 to over 300 fathoms (one fathom = 6 feet) deep – that is a lot of rope. At each measure, they sighted a bearing to two or more locations on shore to locate where on the chart they could mark the depth. It’s surprising how closely their data matches what we found with the use of sophisticated modern techniques.

So how is it done? A good activity in the classroom is to make a sounding box with an ocean floor shaped on the bottom of the box. The top is covered and marked with a grid. Skewer sticks can be inserted at the grid corners, pulled out, measured, and transferred to another grid. A map is made. If only it were as easy. Simply put, modern hydrographers ping sound waves (sonar) from the bottom of the ship. The sound waves travel through the water to the ocean bottom and bounce back. We know how fast sound travels so measurements of time can be made and the distance calculated – just like the skewer sticks. If only it were as easy!

See the following website for information on hydrographic survey techniques. http://www.nauticalcharts.noaa.gov/mcd/learnnc_surveytechniques.html

My learning curve has been high as I have tried to understand all the moving variables that need to be taken into account before an accurate map can be made.

Here’s what I am beginning to understand:

  • Starts with referencing benchmarks – both vertical and horizontal (see blog, May 7) to gain a standard of tidal variation (high and low tide can vary by as much as 20 feet) and GPS location.
  • A measurement is made from the ship’s deck to the water surface. The twin sonar beams are located on the bottom of the ship. We know how far it is from the bottom of the ship to the deck – subtracting the deck to the water line gives the distance below the surface the sonar equipment is found at the time of measurement.
  • The chart is marked off in rectangles. A line is marked for the ship to follow. Traveling at 10 knots, the multibeam equipment located on the bottom of the ship pings sound waves and measures how long they take to return from the bottom. A broad swath of ocean bottom can be measured at the same time. These data are transferred to a computer in the plotting lab where the computer archives it and generates visual images as they come in.
  • The speed of sound varies in different water conditions, including temperature and salinity. Making it more complicated, temperature and salinity varies by depth in the water column beneath the ship. To capture these variables, we cast out a Moving Vessel Profiler (MVP) behind the ship while we travel along. The MVP looks like a small torpedo and is affectionately referred to as the fish. Attached is a sensor that reads temperature, conductivity (a measure for salinity), and depth. These data are transferred along a cable bound within the attached line to a computer on board the ship. “Casting” the fish means letting the line out until the fish approaches the bottom of the ocean – or 500 meters of line – whichever comes first. At that point the fish is retrieved. The data acquired as the fish makes its journey is transferred to the Plotting Lab computer.

    The sensor on the "fish" captures temperature, conductivity, and depth data on the water column beneath the ship.
    The sensor on the “fish” captures temperature, conductivity, and depth data on the water column beneath the ship.
  • As the ship moves along the ocean surface it is subjected to constant movement. It pitches up and down from front to back (pitch), rolls side to side (roll), and rises up and down with the ocean swells (heave). As the survey data is collected, heave, roll, and pitch data is captured to allow for adjustments in the sonar data. All of this varies further with the tide level. All these data are captured and fed into the Plotting Lab computer.

    Data from the ship's multibeam sonar comes to the Platting Lab
    Data from the ship’s multibeam sonar comes to the Plotting Lab
  • The ship travels its projected line, turns around and comes back on another.
  • Small boats with similar beams are dispatched to capture the same measurements closer to the shoreline where it is too shallow for the ship (for tomorrow).
  • This continues until the full ocean bottom in our project area is captured.
  • Finally all these data sets are brought together and stored.
  • During the off season, the data sets are utilized to generate the finished nautical charts ending a long, sophisticated process.

Personal Log: Life on the sea

I have to admit the living spaces on board a working ship are a bit tight. My “state room” measures approximately 10’ x 12’ and is shared with a roommate.  In that space are our bunk beds, a sink, desk, and locker closets. I can’t sit up in bed without hitting my head on the bunk above. Shared between two rooms is a bathroom that is only 4’ x 8’ with a head (mariner’s term for a toilet) and shower. All this space rests on a floor that drops with the curve of the ship approximately 10” from one end to the other. The hallways in the ship are narrow and the stairways steep. Everything is bolted or tied to the floor or table to keep them from being tossed about in choppy waters.

While tight, I have yet to hear anyone wish for more. Perhaps the salt that runs in their mariner blood provides the sustenance they need to thrive in these close quarters at sea.

While my shipmates will call the Rainier home for the duration of the research season, I will be on board for only two weeks before I return to the comforts of my own home and spacious bed.  I have to respect these hardy folk for who they are and all they do.

Science and Technology Log: Setting Benchmarks

Morning briefing
Morning briefing

To conduct accurate surveys of the ocean bottom, clear reference points must first be established. Today, I joined a shore team to permanently set official benchmarks into the rock. Yesterday a team located two existing benchmarks in Burroughs Bay, including one put in place in 1891. A hole had been chiseled into the rock followed by a circle around it and an “X” crossing through the hole from one side of the circle to the other. Above the letters B and M (benchmark) were carved in the rock. Weathering and plant growth provided a challenge. There is something intriguing in the transcendence of time, updating work that was performed over a century ago.

To establish a vertical standard, three new brass benchmarks were cemented into rock with the intention of lasting into the next century. All five benchmarks were precisely located to reference elevation to local tidal data acquired through an electronic tidal gauge installed to capture 30 days of high and low tide data. A diving team anchored one end of a line underwater well beyond the reach of low tide. The other end rose on land high enough to be protected from high tide. These tidal data will be referenced to a visual measurement taken every six minutes for three hours from a vertical staff we installed.
