Science and Technology Log

The Wet Lab:

In addition to interviewing members of the crew, working on my blog, and doing a bit of independent research, I am here to help in the wet lab. What does this entail? It begins with waiting. First, there is a marine mammal watch that lasts for 10 minutes. If an animal is within 500 meters we wait until it moves off. Then a second 10-minute watch is started. We continue monitoring mammal activity even after the net is deployed. Sometimes the navigation crew scouts the transect first to make sure the ocean floor won’t cause issues with the net when it is deployed.

Deploying the net is a team effort among deck crew, navigation officers, and scientists. Once the net is off the reel and in the water, the crew disconnects the wire line to the reel and it is transferred to the doors. Winches connected to the trawl doors take the weight of the load. Depending on fish sign, the net is payed out according to depths the acousticians wish to fish at.

The length of time the net is streamed is also determined by the scientists. They monitor how many fish are going into the net via an FS70 third-wire trawl sonar which has a similar function to Doppler radar. Nicknamed “the turtle,” it is attached to the head rope. Sometimes there’s a “thunderstorm” of fish, and sometimes a “drizzle.” Once the acousticians have determined how much to punish the wet lab (joke), the lead scientist calls, “haul back.” The average fishing time is around 20 minutes, although it can be as little as a half minute in a fish thunderstorm or as long as 40 minutes in a fish drizzle. A sensor attached to the net records temperature and depth.

Once the net is back on board and we get a look at the catch size, a decision is made where to dump the haul. Under 100kg (220lbs), the catch goes in a black crate; over 100 kg, it goes into a hopper that leads to a conveyor belt inside the wet lab. The hopper door is opened a little at a time to avoid a fishy waterfall over the sides. Dominant species—hake in this case—go down the belt, and all other species are pulled out and sorted.

All our hauls to date have been on the smaller side, and so the net is hoisted and dumped into the black crate containing three smaller baskets. The deck crew slides this through double doors leading into the wet lab and we begin sorting species. Crew members often linger to see what cool things have been hauled aboard, and when they are impressive enough—like medium-sized squid and King-of-the-Salmon almost as long as you are tall—we take photos of each other, shaking our heads at the marvel of it. Ethan weighs the biomass of creatures that are not hake, then they go down the chute back to the ocean and return to the food chain.

Jenny, wearing black overalls, rubber boots, gloves, and a Teacher at Sea hat, stands in the wet lab surrounded by plastic sorting bins. With her right hand, she hoists up a very large fish by its gills. it is pinkish in color, with a large head and a body that tapers all the way from a large round eye to the tail. the top of its open mouth is about in line with Jenny's hat, and the tip of its tail rests on her boot. — A King-of-the-Salmon almost as long as me!

The goal is 400 hake per haul, and to date we’ve counted 282 as the biggest catch. A handful of other species are measured, usually others that are commercially fished.

Depending on the number of hake collected, 50 have otoliths (ear bones) removed for aging and a random 10 of these have their stomachs examined. Krill and Blue lampfish appear to be favorite foods. A measuring device for the stomachs provides us with a number for the volume of food in their stomach.

If the ideal haul is taken, 350 hake are sexed and measured. The sexes are sorted into baskets of different colors: green (“little green men”) for the males and white (“snow white”) for the females. A set number of females have their liver and gonads taken for examination. I have yet to find out why just the females have this done.

After we’ve processed everything we clean the lab after each haul. If you don’t, the fishy aspect can get out of control quickly. Allegedly herrings are the smelliest.

Taxonomy of Sights

Day 3. Multiple whale spouts throughout the day. Species that appeared in our hauls: King- of-the-Salmon, Pyrosomes, Spiny dogfish, Brown cat shark, Glass shrimp, Jewel squid, and a viperfish that looked like the stuff of nightmares! A couple of albatross cruised behind us during one of the trawls, hoping for some fishy treats.

Day 4. One Jack mackerel mixed in with hake, a monitored species, so we took its measurements. One partial squid tangled in the trawl net.

You Might Be Wondering…

Do you have to wear a life jacket the whole time?

Life jackets and hard hats are required on the aft deck when there is an operation in progress. The safety mantra is, “If you don’t need to be on the deck, don’t go on the deck.” Each of us carries a PLB, or personal locator beacon, in the event of a worst-case scenario. Life jackets, along with immersion suits, are located in staterooms as well as the wet lab. No, I do not wear a life jacket while sleeping, showering, and spending time on the interior of the ship. Safety equipment is never far away. Emergency egress arrows show you a way out, and there are three emergency shower and eye wash stations on the ship. There are also devices called EEBD (Emergency Escape Breathing Device) that contain 15 minutes of oxygen.

If you have questions you are curious about, please leave them in the comments section!

Floating Facts

Nautical Terms
Aft is the back of the boat where the trawling happens. The bow, or forward, is the front of the ship. Port is left, which you can distinguish from starboard because port and left have the same number of letters. Starboard is right. Stairs are referred to as “ladders,” walls are “bulkheads,” not to be confused with “bulwark,” which are the sides of the vessel above the main deck.

New Blue Economy
The “blue economy” is a new term for me. According to Dr. Richard Spinrad, Under Secretary of Commerce for Oceans and Atmosphere & NOAA Administrator, it’s “a knowledge-based economy, looking to the sea not just for extraction of material goods, but for data and information to address societal challenges and inspire their solutions.”

40% of the U.S. population lives in or near coastal communities. A NOAA article on the blue economy states, “If American coastal counties were an individual country, they would rank third in the world in gross domestic product, surpassed only by the United States and China.” I assume this means as compared to the remainder of the United States that do not qualify as a “coastal community.”

The demands of climate change only hasten the need for information about our oceans and coastal regions. NOAA serves as a foundation for the blue economy, providing free, open source data–temperature, water level, hydrography, fisheries health, pH, salinity, and surface currents to name a few. The shipping challenges that the recent global pandemic posed have increased the need for U.S. seaports to add terminals and piers. Maritime commerce is expected to triple by 2030.

Educator Resources
If you are an educator and have not been to the Oregon Coast STEM hub website, it is highly recommended. It is managed by Oregon State University’s Hatfield Marine Science Center. There’s something for everyone, even if you and your students aren’t located in Oregon.

While aboard I learned that the University of Oregon—my alma mater—also has a Marine Biology program. In fact, U of O’s Oregon Institute of Marine Biology (OIMB), located in Charleston, Oregon near Coos Bay, is a field institute like the Hatfield Marine Science Center. OIMB also has a section on its website for educators including lessons and resources. There is some crossover with the STEM hub, but both sites are valuable and worth examining. Note that at the time of my visit to the OIMB site there were some broken links on the resources page.

Personal Log

The NOAA Ship Bell M. Shimada has seven levels: (from top to bottom) flying bridge–where our marine mammal and bird observers spend much of their time; bridge–where officers spend much of their time, where navigation happens, where a marine mammal watch happens before a trawl, where the boatswain, also known as a bosun, (deck boss) has a view of the nets going in and out, operates the net reel and communicates between nav crew and deck crew; officers berth–along with the hospital and quarters for the Chief Engineer; science berth–including lounge and offices; labs, mess deck, and access to the aft deck where the net is pulled in and the catch is transferred to the wet lab; deck crew berth–along with gym, winch and trawl rooms, centerboard access; and finally additional machinery rooms–including one for the bow thruster. I have been promised a tour of the engine room toward the end of our cruise, so I am looking forward to that!

Monday and Tuesday were great days, particularly Tuesday. I felt good, held all my meals, talked with a variety of crew members about their work, and got my hands dirty for the first time in the wet lab. Julia Clemons said of Tuesday, “It was a great day for science!” We made a record number of trawls—three—for the 2023 survey thus far.

Highlights of Wednesday’s trawl were part of a squid tangled in the net (much larger than the jewel squid), and some baby hake. I got into a rhythm assisting Ethan with entering data. He measured, weighed, sexed, examined stomach contents of some, and removed otoliths. I supported by entering the barcodes from the otolith collection vials manually (nothing new for a librarian who has her own trouble with temperamental barcode scanners from time to time), entered sex and maturity level, entered data on stomach contents (primarily blue lanternfish, and euphausiids, aka krill).

Librarian at Sea

“The world turns and the world spins, the tide runs in and the tide runs out, and there is nothing in the world more beautiful and more wonderful in all its evolved forms than two souls who look at each other straight on.” ~Gary D. Schmidt, Lizzie Bright and the Buckminster Boy

In this middle-grade novel, a friendship is formed between Turner Buckminster, son of a preacher, and Lizzie Bright Griffin, a resident of Malaga Island. Malaga is located off the coast of Maine and was founded by people who were formerly enslaved. The quote above refers to a moment when the two young people are in a boat and Turner comes eye to eye with a whale five times the size of the dory they are traveling in. It reminds me a little of looking into the eyes of the creatures who come aboard in our net. I wonder if some are still capable of seeing…

Hook, Line, and Thinker

The NOAA Teacher at Sea program requires fortitude, flexibility, and following orders.
On Monday the crew followed orders for our first safety drills. These include special signals indicating fire, abandon ship, and man overboard. The science crew (which includes me) musters in the wet lab for fire, where the Chief Scientist reports muster to the bridge. “Muster” means that all are assembled who should be there. During an abandon-ship drill, the crew is split up between six life rafts, three on each side of the ship. New members of the crew try on their immersion suit, a bulky get-up that guards against hypothermia and increases flotation. I tried on two different sizes, and while neither was quite right we concluded bulkier was better than too small. As the XO put it, “It will save your life. Throw in your shoes and a loaf of bread and you’re good to go!” The man overboard drill requires the science crew to muster on the flying bridge where we locate the individual in trouble (in the case of a drill, a couple of buoys tied together) and point.

Can you think of an example in which following orders may save your life?

A Bobbing Bibliography

On the bridge you will find binoculars on the sill of many windows. You will also find whale and dolphin identification guides, as well as one for birds. Some of the binoculars are “reticulated.” When you look into the eyepieces of these you see a series of fine lines (reticules) to determine distance between marine mammals and the vessel. Line up the top line to the horizon and you have the distance between objects and the ship.

There are many great spots along the Oregon Coast for whale watching that don’t require going out on the ocean. Oregon State Parks has a whale watching site with more information.

The book Whales and Other Marine Mammals of Washington and Oregon, by Tamara Eder and illustrated by Ian Sheldon, is propped up against a window. Through the window we can see a deck of the ship, the ocean, sea spray.

Personal Log

I was asked yesterday by one of my students what life is like aboard the NOAA Ship Fairweather? So I thought I would dedicate this entry to address this and some of the other commonly asked questions from my students.

Life on board the ship is best described as a working village and everyone on board has many specific jobs to ensure the success of its mission; check my “Meet the Crew” blog. The ship operates in a twenty four hour schedule with the officers rotating shifts and responsibilities. When the ship is collecting ocean floor data, the hydrographers will work rotating shifts 24 hours a day. With so much happening at once on a working research vessel, prevention of incidents is priority which leads to the ship’s success. A safety department head meeting is held daily by the XO (executive officer of the ship) to review any safety issues.

During times when the weather is not conducive for data collection, special training sessions are held. For instance, a few days ago, the officers conducted man over board drills. Here, NOAA Officers practice navigating the ship and coordinating with deck hands to successfully rescue the victim; in this case it’s the ship’s mascot, “Oscar.”

(Fun fact: at sea, ships use signal flags to communicate messages back and forth [obviously, this was more prevalent before the advent of radio]. For example: the “A” or “Alpha” flag means divers are working under the surface; the “B” or “Bravo” flag means I am taking on dangerous cargo [i.e. fueling]; and the “O” flag means I have a man overboard. The phonetic name for “O” is, you guessed it, “Oscar” … hence the name. You can read about other messages here: https://en.wikipedia.org/wiki/International_maritime_signal_flags).

Precision and speed is the goal and it is not easy when the officer is maneuvering 1,591 tons of steel; the best time was 6:24. This takes a lot skill, practice and the ability to communicate effectively to the many crew members on the bridge, stern (back of boat), and the breezeways on both port and starboard sides of the ship. Navigating the ship becomes even more challenging when fog rolls in as the officers rely on their navigation instruments. Training can also come in the form of good entertainment. With expired rescue flares and smoke grenades, the whole crew practiced firing flares and activating the smoke canisters. These devices are used to send distress signals in the event of a major ship emergency. I had the opportunity of firing one of the flares !

What are the working conditions like on board?

At sea, the working environment constantly changes due to the weather and the current state of the seas. Being flexible and adaptive is important and jobs and tasks for the day often change Yesterday, we experienced the first rough day at sea with wave heights close to ten feet. Walking up a flight of stairs takes a bit more dexterity and getting used to. At times the floor beneath will become not trustworthy, and the walls become your support in preventing accidents.

Where do you sleep?

Each crew member is assigned a stateroom and some are shared quarters. Each stateroom has the comforts from home a bed, desk, head (bathroom & shower) sink and a port hole (window) in most cases. The most challenging component of sleeping is sunlight, it does not set until 11:30 pm. No worries, the “port holes” have a metal plate that can be lowered. It is definitely interesting looking through the window when the seas are rough and watching the waves spin by. Seabirds will occasionally fly by late at night and I wonder why are they so far out to sea ?

Generally, when sharing a stateroom, roommates will have different working shifts.

Meals are served in the galley and it is amazing! It is prepared daily by our Chief Steward Tyrone; he worked for the Navy for 20 years and comes with a lot of skills and talents ! When asking the crew what they enjoy the most on board the ship, a lot of them mention the great food and not having to cook.

Are there any activities?

Keeping in good physical shape aboard any vessel out at sea is important. The Fairweather has a gym that can be used 24 hours a day. The gym has treadmills, elliptical, weights and a stair climber.

ExerciseRoom — The exercise room – photo by Tom

There is the lounge where movies are shown in the evening. Interestingly, the seats glide with the motions of the waves. Meetings are also held here daily, mostly safety briefings.

What are the working hours like?

During any cruise with NOAA, there is always things that come up that were not planned, staff and schedules are adjusted accordingly. On this leg of the trip during our transit back to Kodiak Island, we stopped by Nome, Alaska, to pick up a scientist from NOAA’s Pacific Marine Environmental Lab PMEL office. One of their research buoys separated from its mooring and went adrift in the Bering Sea (it drifted over 100 miles before we were able to catch up to it. The Fairweather was dispatched to collect and store the buoy aboard, after which it will eventually be returned to PMEL’s lab in Seattle Washington.

The place with the most noise is definitely the engine room. Here, two sixteen piston engines built by General Motors powers the ship; the same engine power in one train engine ! It is extremely difficult to navigate in the engine room as there is so many valves, pipes, pumps, switches and wires. Did I mention that it is very warm in the room; according to the chief engineer, Tommy, to maintain a healthy engine is to ensure that the engine is constantly warm even during times when the ship is docked.

Until next time, happy sailing !

Mission: Hydro Survey

Geographic Area of Cruise: Southeast Alaska – West Prince of Wales Island Hydro Survey

Date: June 5th

Weather Data: Full cloud cover, rain showers.

Location: Ketchikan, 55.3422° N, 131.6461° W

Personal Log

Today the boat is leaving Ketchikan. Breakfast is between 7-8 and as I sat with my plate of eggs and toast, I watch the hustle and bustle of life on a boat preparing it to get underway. There are many challenges to sailing a ship, and while I had a general idea, I did not understand how much organization, safety protocols, equipment and manpower it takes to make a boat run, complete science research, and be a safe place for people to live and work. This first couple of days on the boat have been not focusing on the science research being done here, but one of getting a sense of how a research vessel works, the myriad of roles and jobs that are done here and the multiple hats that most people wear.

The ship’s communication system put an all-hands-on-deck call to help with unloading food deliveries at port. Here we passed boxes one by one from the truck up on to the ship and in to the kitchen storage areas where the stewards will unload and store the food ready for our meals and snacks. There are three main meals per day: breakfast (7-8), lunch (11-12) and dinner (5-6). In between these times snacks and drinks are readily available. What I am finding too is that many people work a shift system, or are on the smaller boats away from the ship for a day. Food for them is packed or available and no one goes hungry. Snacks and drinks are available 24-7 too. The meals are diverse and food is plentiful. I hope to talk with the stewards to figure out how they plan the menus and order all the food, to feed about 50 people for a three-week period.

Next came a safety briefing and tour. The first thing I had to do was to practice putting on my emergency gear – how to describe it? This ‘dry-suit onesie’ would allow me to be in the Alaskan waters and survive. While my whole body is covered except for my eyes, the suit contains a life vest, and would allow me to easily float upright. As you can tell from the photo, the main issue I had was with my hair getting in my face, a common occurrence apparently for those of us with long hair. Next we learned about all of our stations and our role for different scenarios: fire, man-over-board, and a full ship evacuation. We learned about the different alarms that would be sounded, the types of fire extinguishers, where the medical office is, and where the AED’s are. We were also reminded that in each stateroom is a breathing device kit that is can be used to provide ten minutes of oxygen, should it be needed.

Pulling out of port yesterday, the boat first only went a few hundred yards up the narrows. The next stage was to ‘top up’ on fuel – 18,000 gallons of fuel. The boat can hold much more but the cost in Ketchikan is less than further north so it pays to fill up now. As you can imagine there are big safety issues with fueling of boats and during this time, several temporary bans were put in to place on the ship so that no sparks of any kind were made (no cooking, welding etc). The fuel is stored in several large tanks. The tanks are not connected to each other and each can be turned off individually in the event of a fire or leak. Earlier that day too we had also filled up with water.

There are many conservation and environmental practices put in to place that I have already seen on the ship. There are many protocols put in to place to protect both the environment and to conserve resources. During the fueling, a ring (oil boom) was put around the ship so that if there were an accidental fuel spill or leak, it would be contained on the surface of the water. Laundry is ‘closed’ until next weekend and only full loads are allowed in order to conserve fresh water. Water can be made from seawater using equipment on the ship, but it costs $8/gallon to run the equipment, so conservation is the first measure put in place.

We also have practiced emergency drills. In these drills, everyone has a station to go to and a job to do. The fire drill mimicked a fire in the generator room and a person receiving burns. What’s interesting to realize it that people wear multiple hats on the ship and so everyone needs to know what to do and how to help. Formal fire fighting equipment is worn by trained people, radios are used to communicate between groups, diagrams of the ship are pulled out and drawn on and labeled to keep account of who has been tasked to do what and where the situation is located. Out at sea, the fire department and the medics cannot be called. The staff members on the ship are the medics and the fire department. During the drill a person role-played being the burn victim, so not only were firefighters needed but also medics. After the drills, everyone meets to debrief. Ideas and observations are shared. Communication is crucial and common here.

With communication at the forefront, there are many mechanisms put in place to make sure the people on board know the specifics of the mission each day and their role in the mission. There are different departments in the boat, but one cannot function without the other. People are hired as Survey crew, Engineers, Deck crew, Stewards, Electronic Tecnicians and as NOAA Corps officers. There are also visitors on the boat, such as myself, some who are with the boat for the whole season, others like myself for a few weeks. Schedules are placed around the boat indicating who is on what shift. Meetings are held at 8am each day with the science and deck teams to discuss where the small research boats are surveying that day. During these briefings safety reminders and weather conditions are discussed as well as the location of where each boat will be. Boats radio in each hour for safety. Department heads meet daily to share their updates, keeping everyone up to date with different aspects of the ship. Debrief sessions happen at the end of each research day after dinner. Everyone participates as no one person’s job is isolated here. Issues and concerns are dealt with and go in to the decision making for the following day. Communication is key.

Fact of the day:

The Fairweather is divided in to 26 fire zones to help with safety and fire fighting. All the doors operate manually and many internal doors are held open by a magnet. In the event of a fire, the doors can be closed instantly from the Bridge, using a switch to stop the magnets working.

Word of the day: Muster

This is the term used when all the people gathered in the correct place for the fire/emergency drill. Roll was taken and we had a ‘full muster’.

What is this?

What do you think this is a picture of? (The answer will be in the next blog installment).

(Previous answer: Rubber boots with spikes in to help with traction. Here on the boat, and in many parts of Alaska waterproof footwear is very useful. While the boots the staff here don’t have spikes in them, these were on display in the Southeastern Alaska Discovery Center.

Science and Technology Log

ENS Steve Wall collecting a bottom sample.

Wednesday, I went on a launch to do bottom sampling and cross lines. Wednesday was our last day of data acquisition, so the motto on the POD (Plan of the Day) was “LEAVE NO HOLIDAYS! If in doubt, ping it again!” Bottom sampling is pretty straight forward. We drive to designated locations and drop a device that looks a little like a dog poop scooper down into the water after attaching it to a wench. The device has a mechanism that holds the mouth of it open until it is jarred from hitting the bottom. When it hits the bottom, it snaps closed and hopefully snatches up some of the sediment from the bottom. Then, we reel it up with the wench and see what’s inside.

We took 10 bottom samples and most were the same. We had a fine brown sand in most samples. Some samples contained bits of shell, so we documented when that was the case. At one location, we tried for samples three times and every time, we got just water. This happens sometimes if the sea floor is rocky and the device can’t pick up the rocks. If you try three times and get no definitive answer, you label the sample as unknown. Two times we got critters in our samples. One critter we found was an amphipod most likely. The second critter was shrimp/krill-like, but I don’t know for sure. Cross lines are just collecting sonar data in lines that run parallel to the previous data lines. This gives us a better image and checks the data.

Unknown shrimp/krill critter from bottom sample.

Thursday, we closed out the tidal station at Terror Bay. This entailed doing staff observations, a tidal gauge leveling check, and then break down everything including completing a dive to remove the orifice. Since I have already taken part in a tidal gauge leveling check, I was assigned to the staff observations and dive party. As I mentioned in an earlier post, for staff observations you just record the level of the water by reading a staff every six minutes for three hours. We did this while on a boat, because the tide was pretty high when we got started, so we wouldn’t be able to read the staff if we were on shore. Again, the reason we do staff observations is so we can compare our results to what the tidal gauge is recording to make sure the tidal gauge is and has been working properly.

While doing staff observations, I saw a small jellyfish looking creature, but it was different. It had bilateral symmetry instead of radial symmetry. Bilateral symmetry is what we have, where one side is more or less the same as the other side. Jellyfish have radial symmetry which means instead of just one possible place you could cut to make two side that are the same, there are multiple places you can cut to make it the same on each side. Also, the critter was moving by flopping its body from side to side which is nothing like a jellyfish. I had to figure out what this was! In between our observations, Jeff, the coxswain, maneuvered the boat so I could scoop this guy into a cup. Once we finished our staff observations, we headed to the ship. I asked around and Adam (the FOO) identified my creature. It’s a hooded nudibranch (Melibe leonina). Nudibranches are sea slugs that come in a beautiful variety of colors and shapes.

ENS Wood and ENS DeCastro diving for the orifice.

After a quick return to the ship, we headed back out with a dive team to remove the orifice from underwater. Quick reminder: the orifice was basically a metal tube that air bubbles are pushed out of. The amount of pressure needed to push out the air bubbles is what tells us the depth of the water. Anyways, the water was crystal clear, so it was really neat, because we could see the divers removing the orifice and orifice tubing. Also, you could see all sorts of jellyfish and sea stars. At this point, I released the hooded nudibranch back where I got him from.

Just as we were wrapping up with everything. The master diver Katrina asked another diver Chris if he was alright, because he was just floating on his back in the water. He didn’t respond. It’s another drill! One person called it in on the radio, one of the divers hopped back in the water and checked his vitals, and another person grabbed the backboard. I helped clear the way to pull Chris on board using the backboard, strap him down with the straps, and pull out the oxygen mask. We got him back to the ship where the drill continued and the medical officer took over. It was exciting and fun to take part in this drill. This was a very unexpected drill for many people, and they acted so professional that I am sure if a real emergency occurred, they would be prepared.

Personal Log

Sadly, this was most likely my last adventure for this trip, because I fly out tomorrow afternoon. This trip has really been a one-of-a-kind experience. I have learned and have a great appreciation for what it takes to make a quality nautical chart. I am excited about bringing all that the Rainier and her crew have taught me back to the classroom to illustrate to students the importance of and the excitement involved in doing science and scientific research. Thank you so much to everyone on board Rainier for keeping me safe, helping me learn, keeping me well fed, and making my adventure awesome! Also, thank you to all those people in charge of the NOAA Teacher at Sea program who arranged my travel, published my blogs, provided me training, and allowed me to take part in this phenomenal program. Lastly, thank you to my students, family, and friends for reading my blog, participating in my polls, and asking great questions.

Did You Know?

1 knot is one nautical mile per hour which is equal to approximately 1.151 miles per hour.

Challenge:

Can you figure out what my unknown shrimp/krill critter is?

Science & Technology Log

The past week/ week and a half, docked alongside the US Coast Guard pier in Kodiak – it was easy to see people settle into a routine. This morning, however, we are preparing to leave the Coast Guard base – there is something in the air. Without it being spoken, it is clear both the NOAA Corps officers and the wage mariners are excited to get underway. THIS is what they signed up to do!

The Rainier is 231 feet in length, with a breadth (width) of 42 feet. She cannot be run by a single person – it takes a team, a large team, to operate her safely. Aboard the Rainier there is a crew of NOAA Corps Officers, including Commanding Officer CDR Van Den Ameele (CO), Executive Officer LCDR Holly Jablonski (XO), Field Operations Officer LT Russ Quintero (FOO) and a number of Junior Officers. There is also a full staff of Surveyors, Stewards, Deck Hands, Engineers, a Chief Electronics Tech (ET) and an Electronics Eng. Tech (EET). All of the people on the Rainier’s nearly 50 member crew take on more than one job and help with whatever is asked of them. It takes a team of people to drive the ship, a team to deploy launch boats, a team to process survey data, a team level tide gauges, a team to keep the boat in good maintenance, etc…

This is the Crew Board for all team members currently aboard the Rainier. ENS Micki Ream updates the crew board each leg.

This morning, in preparation for getting underway, all NOAA Corps officers met for a Nav (navigation) Briefing, to go over the Sail Plan, to make sure all necessary parties were prepared and informed. NOAA Corps is one of seven uniformed services in the United States. Its commissioned officers provide NOAA with “an important blend of operational, management, and technical skills that support the agency’s science and surveying programs at sea, in the air, and ashore.” (www.noaa.gov) The Sail Plan, prepared today by Junior Officer, ENS Cali DeCastro, includes step-by-step guidelines for sailing to our next destination. For each location or waypoint along the route, the sail plan gives a course heading (CSE), Latitude and Longitude, distance to the that point (in Nautical Miles), the speed (in knots) the ship will be cruising at to get to that point, and the time it will take to get there. Today we are headed to Japanese Bay, and our cruise to get there is about 98 Nautical Miles and will take us almost 9 hours.

It is important to note that nautical miles and knots at sea are different than linear miles and miles per hour on land. Nautical miles are based on the circumference of the Earth, and are equal to one minute of latitude. (http://oceanservice.noaa.gov/facts/nauticalmile_knot.html) Think about the Earth and what it would look like if you sliced it in half right at the Equator. Looking at one of the halves of the Earth, you could then see the equator as a full circle. That circle can be divided into 360 degrees, and each degree into 60 minutes. One minute of arc on the Earth is equivalent to one nautical mile. Nautical miles are not only used at sea, but also in the air, as planes are following the arc of the Earth as they fly. 1 nautical mile = approximately 1.15 miles. A knot is a measurement of speed, and one knot is equivalent to 1 nautical mile per hour.

It is also important to be aware of all the safety procedures on board. There is a lot to keep track of – but the Rainier is well prepared for any kind of emergency situation. Prior to departing the Coast Guard Base this morning, our emergency alarms and bells were tested. Emergency bells and whistles are used during a Fire Emergency, an Abandon Ship situation, or a Man Overboard situation.

In any situation, every crew member has an emergency billet assignment. This assignment tells you where to muster (meet), what to bring, and what to do – dependent on the situation. For fire and emergency, abandon ship, and man overboard each person has a different assignment. Within 24 hours of setting sail, the entire crew does safety drill practice (We did this in the early afternoon today!) For fire and emergency both the general alarm bell and the ship’s whistle will continuously sound for ten seconds; for an abandon ship situation, seven short blasts on the ship’s whistle and general alarm bell will sound, followed by one prolonged blast; and for a man overboard there will be three prolonged blasts of the ship’s whistle and general alarm.

Safety is not only a concern in emergency situations – it is at the forefront of all operations aboard the ship. Proper safety equipment is donned at necessary times, especially when working on deck or on the survey launches. Personal Floatation Devices (PFD) are worn anytime equipment is being deployed or handled over the side along with safety belts and lines for those handling equipment over the side. Every crew member is issued a hard hat and must be worn by everyone involved in recovery or deployment of boats and other equipment. Closed toed shoes must be worn at all times by all crew and crew must be qualified to handle specific equipment. Everyone is also issued an Immersion Suit (survival suit), affectionately nicknamed a Gumby Suit! The Immersion suit is a thermal dry suit that is meant to keep someone from getting hypothermia in an abandon ship situation in cold waters.

Personal Log

Believe it or not – I have made a lot of connections from the Rainier to my school. At the bottom of our daily POD’s (Plan Of the Day), the last reminder is, “Take care of yourself. Take care of your shipmates. Take care of the ship!” The environment here has not only made me feel welcome, but safe as well.

I even felt safe when they let me man the helm (steer the ship). Out of picture, Officer LTJG Adam Pfundt and Able Seaman Robert Steele guide me through my first adventure at the helm!

For my Students

Here is a wildlife update. I saw Whales today! I think there were Humpback Whale. I saw quite a few blowing out near the ocean service. I marked three in my graph because I only saw three jumping and playing in the water!

Some questions to reflect on…

Why is teamwork important? What can you do to be a good team member?
Can you make any connections between the mission and rules I am learning on the ship and the mission and rules you are learning at school?
