Science and Technology Log 

An often paraphrased quote by Robert Burns goes, โ€œThe best laid plans of mice and men often go awry.โ€  Well, maybe that phrase also applies to fish. 

The original plans for this leg of the survey were to head out to sea on August 8th.  However, a winch on NOAA Ship Bell M. Shimada stopped working before we took off.  The winch is important as it helps to bring in the net which we need to catch the fish.  It was a two day repair. 

Then on the 10th we were all aboard and ready to leave when the wind decided to kick up.  It was coming in at such an angle and strength that we did not have enough power to push away from the dock safely.  So, we stayed in port for another night. We made the most of it by walking to the Oregon Coast Aquarium.  It was amazing to be with the scientists as we walked through the exhibits.  They have so much knowledge and experience working with the creatures on display. 

Thankfully, the next day, the wind cooperated, and right around 14:50 on August 11th, we were able to set off.  There were cheers and fist pumps as we began our journey. 

In our mission we are taking a survey of the West Coast Pelagics, but specifically we are looking for five main fish: Pacific sardine, jack mackerel, northern anchovy, Pacific mackerel, and Pacific hake.  I will be focusing on CPS, Coastal Pelagic Species, which are the sardines, anchovies, and both mackerels.  Those will be caught during the night time shift that I will be working, midnight to noon.  The reason we catch them at night is that during the day they are spread out and feeding, but at night they come back together for safety. 

This is important work because with the data we collect we will know more about the population, size, and location of the populations and that provides guidance on what should be done for commercial fishing of those populations.  One way we are able to be more efficient in catching the fish is by using certain tools to help us know where the fish are.  We use acoustics technology to determine where, how many, and what kind of fish. 

Today I helped get a TDR, Temperature Depth Recorder, ready to attach to the net.  This sends information back to the ship about the depth of the net and the temperature of the water.  The information when combined with what we know from the acoustics helps us catch what we are after.

Personal Log

Once again following the theme of the day, adaptation has been key.  I knew my schedule going into this adventure was going to require me to change my sleep schedule.  Once the departure date was thrown back three days, there was also no way for me to keep the midnight to noon schedule.  So, I am back today trying to adjust. 

I am also trying to adapt to the motion of the sea.  I brought sea sickness medicine and have been taking it regularly as prescribed, but I am still feeling the effects of the motion a little bit.  One good trick has been getting outside and looking at the horizon.  That has helped quite a bit.  I also enjoy being in the wet lab.  It is a bigger space and that is helping me fight back the queasy feeling. 

The food onboard has been terrific.  I am eating well.  Our main stewardโ€™s name is Phil.  He makes some amazing food.  That is one thing I have not had to adjust to in any way. 

I have the internet and am able to make Wi-Fi calls.  Back home there was a flash flood.  A lot of friends and family are dealing with the loss of their things.  Thankfully, I have not heard any reports of people having been hurt.  It is tough to be away from friends and family.  Thankfully, everyone on board has been really nice.  It makes a tough situation easier when you have friends to talk with.  I am looking forward to not feeling sea sick soon and having amazing learning experiences in the days and weeks ahead.

Did You Know?

Greenwich Mean Time is the local time at the Royal Observatory in Greenwhich, England where the Prime Meridian was established in 1884.  It is used as a reference point for telling time all around the world.  On the ship it can be difficult to keep track of time.  The GMT is a way for all of us who come from different time zones and are on different schedules to keep track of what time things are happening.  

Can you identify this species?

Science and Technology Log

Once the trawl is completed, the codend is unloaded onto a conveyor belt for sorting. Usually, we just sort by species, picking out any organisms that arenโ€™t pollock and storing them in separate baskets. Overall, Iโ€™ve been surprised with how โ€œcleanโ€ or uniform the catches have been. We will usually have some jellyfish, but other than that we tend to have only a few fish of other species in a catch with hundreds or thousands of pollock.

Pollock on the conveyor belt. We can see the orange rain coats and long yellow gloves of two scientists standing nearby.
The catch is first emptied onto a conveyor belt where it is sorted by species.

When the catch has a mix of juvenile and adult pollock, weโ€™ll also sort them by size, which roughly correlates to age group. The size cutoff used for sorting is only an approximation of age (the exact age is determined later), but it is still useful in ensuring that we sample a consistent number of each size class in every trawl.

Distinguishing between the larger juveniles and smaller adults on the belt can be tricky, so on one trawl we got creative and found what we named a โ€œmeasuring fish.โ€ This fish was the smallest length that had been designated as an adult in the previous trawls โ€“ anything smaller we left on the belt with the juveniles and anything larger we put in a separate basket with the adults. While not the most conventional solution, it served our purpose well and showed that anything can be made into a measuring instrument!

Nick is wearing a heavy orange rain coat and long yellow gloves. He holds up two pollock fish vertically, comparing their lengths to one another. We see more fish on a sorting table in the background.

Once the fish are sorted, we take length and weight measurements for a representative sample of all species in the trawl. We measure the length of hundreds of pollock in a given trawl, so luckily the system is very efficient. 

When I length a pollock, Iโ€™ll grab the fish in one hand and place it on the magnetic length board so that its head is against the end at zero. Then Iโ€™ll use my other hand to straighten the fish and place a magnet at the fork of the tail. The length board records where the magnet touches the length board, measuring what is known as the โ€œfork lengthโ€ of the fish.

Pollock on length board; its head faces toward the left side of the board, near a digital meter reading the length. toward the right side, a red magnet is placed at the fork of the fish's tail.
The length board records where the red magnet is placed.

For a subsample of pollock, we will also record the sex and maturity of each individual. To collect this data, weโ€™ll first make a cut along the side of the pollock. This allows us to observe the pollockโ€™s ovaries or testes and compare them to a chart showing the stages of development. Based on the time of year, most of the pollock we catch are in the โ€œdevelopingโ€ stage. Also visible are the pollockโ€™s liver and its stomach, which is often filled with krill!

Matthew, in the foreground, holds a fish up with two hands over a measuring board, and looks at someone over his right shoulder. Nick, in the middle, looks down at the fish that Matthew holds, and a third scientist stands beyond Nick, looking on as well.

For a subsample of the pollock in this group, weโ€™ll also collect otoliths, which are similar to tree rings in that they allow scientists to visually determine the age of the individual. Otoliths are part of pollockโ€™s inner ear, and they help the fish to detect vibrations in the water. Like tree rings, they grow throughout a fishโ€™s life, adding visible layers each year. During times when the fish is actively feeding (usually during the summer), an opaque layer forms around the otolith. In contrast, when the fish is eating less, the otolith layer formed is translucent. By studying otoliths, scientists can determine the age of a fish, as one opaque layer and one translucent layer together represent one year. (Source: https://www.fisheries.noaa.gov/national/science-data/age-and-growth)

One important and sometimes overlooked step in scientific data collection is the clean-up. At Codman Academy, we use the phrase โ€œLeave No Trace,โ€ and I try to model this idea in the fish lab as well. Working with fish can be smelly, and the smell only grows when fish are allowed to sit for extended periods of time. The process of recording sex and extracting otoliths can be especially messy, so we are constantly spraying down baskets and surfaces (and each other!) between data collection steps.

All of the fish that are processed are ultimately disposed of overboard โ€“ usually during the processing of the trawl dozens of seabirds follow the ship in search of discarded fish!

Weโ€™ve certainly had our share of gray days this cruise, and Iโ€™ve become used to falling asleep to the sound of the shipโ€™s foghorn. However, weโ€™ve also gotten a few moments of sunshine and blue sky, providing some great moments for bird and whale watching from the bridge. Being on the night shift, Iโ€™ve also been able to observe a couple of sunsets from the water!

Because we are so far north and west in the time zone, the sun sets very late here, usually around 1 am!

What ocean organisms are you finding?

Each night, the Lasker NOAA Corps Officers, crew, and science team work together to conduct a series of trawls, deploying nets behind the boat to collect samples for the Rockfish Recruitment and Ecosystem Assessment Survey (RREAS).

After the catch from the trawl comes onto the Lasker, scientists identify and measure each of the organisms on board. One of my main tasks during my time as a Teacher at Sea is to help the science team sort and identify the trawl catch each night. A sample of the organisms caught during each trawl, and all of the juvenile rockfish, are collected, labeled and saved for further analysis back at the Southwest Fisheries Science Center Santa Cruz Lab when the science team returns to shore.

Some of the most common organisms caught include pyrosomes, salps (including the large Thetys), krill, and fried egg jellyfish. We also catch a lot of fish, including juvenile anchovy, juvenile hake, many different varieties of myctophid fish, and of course rockfish. To me, some of the most exciting and special organisms caught include the juvenile octopus, all types of squid and king-of-the salmon fish. I am learning so much each day!

View of marine mammal watch station from deck

Each night, and throughout the night, a member of the science team goes on “Mammal Watch” during trawling operations to protect marine mammals. Fifteen minutes before a trawl, a member of the science team goes up to the bridge mammal watch station, and looks for protected marine mammal species like dolphins, sea lions and whales. If a marine mammal is spotted, then the trawl cannot happen until there are no marine mammals within one nautical mile of the ship. When the trawl begins, another scientist begins mammal watch on the deck from the time the net is launched into the water, until it returns to the ship. Again, if a marine mammal is spotted during this time, the trawl will be canceled and the net will be reeled in immediately.

There are also devices attached to the net called โ€œdolphin deterrent devices.โ€ These devices, often called โ€œdolphin pingersโ€ by the science team, activate as soon as they hit water, and emit sounds to deter dolphins and other marine mammals. This helps to keep marine mammals away from the net to prevent them from getting unintentionally tangled, and do not cause harm to marine animals.

What is the NOAA Corps?

The NOAA Corps is one of the nationโ€™s eight uniformed services, and the only one to consist only of officers. All NOAA Corps Officers attend the Basic Officer Training Class (BOTC) at the U.S. Coast Guard Academy and train alongside Coast Guard officer candidates. NOAA Corps Officers support all aspects of the NOAA mission and may be assigned to serve on either ships or aircraft. The Lasker currently has 6 officers aboard, under the leadership of Commander Claire Surrey-Marsden.

Photos: CDR Claire Surrey-Marsden on the flying bridge, Daily safety meeting in the bridge

I got a chance to interview CDR Claire Surrey-Marsden. Originally from the Bronx in New York City, CDR Surrey-Marsden has always been interested in the ocean and has a background studying marine biology from Florida Tech. After college, she interned and then worked for Florida Fish and Wildlife Conservation Commission, where she worked with manatee conservation. She then applied and was accepted into the NOAA Corps, and went on to officer training at the Global Marine and Transportation School (GMATS) at Kings Point Academy. 

NOAA Corps officers alternate between land and sea assignments in different locations. Her second sea assignment was actually on the delivery team of the NOAA Ship Reuben Lasker, then NOAA’s newest fisheries ship. CDR Claire Surrey-Marsden had land assignments in the Marine Mammal Division, Southwest Fisheries Science Center, and in Washington D.C. working with NOAA Rear Admiral Cary. She now returns to the Lasker on her fourth sea assignment as the Commanding Officer, coming full circle from delivering the same ship early in her career.

When asked what advice she would have for a student interested in a marine science career, CDR Surrey-Marsden advises to volunteer for any opportunity/activity, and to do a good job wherever you go.

Book Recommendations

One of the people I work closely with on the ship is scientist Ily Iglesias. Before arriving on the Lasker, Ily just defended for her P.h.D in ocean sciences at University of California Santa Cruz.

Ily is also a mom to a 3 year old daughter, and they love to read books together. Ily gave me several recommendations of her and her daughter’s favorite science-themed books to read together. Ily has been on survey trips several times, and each time before she leaves she enjoys reading the children’s book Love, Mama by Jeanette Bradley. A story about baby penguin with a mama scientist that goes out to sea on a ship, and both a very relevant and helpful book for Ily and her family. Other ocean related favorites include Who’s Afraid of the Light? by Anna McGregor, and Where the Weird Things Are by Zoleka Filander. I’m excited to read these to my preschool students back in Alaska!

How’s the food?

One of the most asked questions of my family and friends from home is asking about what my meals are like at sea. I am happy to report that the food is great! Breakfast, lunch, and dinner are prepared each day by chefs Arnold and Jude, and available to everyone aboard the Lasker at specific times each day. Working the night shift, I typically begin my day with dinner at 1700, and end it with breakfast at 0700. At night while the science team is working, there is always a full salad bar available, as well as sandwich supplies, snacks and leftovers from the day before. Everyone available on the sip eats together in the โ€œmessโ€ – itโ€™s a great time to relax and get to know everyone.

Arriving on the Lasker

We’re off! After landing in San Francisco and driving down to Santa Cruz, I arrived on the NOAA Ship Reuben Lasker by way of small boat transfer. The Lasker was anchored in Monterey Bay, and sent a small boat to pick up myself and some of the science team and crew to be taken aboard. We boarded the small boat, the “RL-2 Shark,” then traveled to the side of the Lasker where we were hoisted up via a winch. I then got a full tour around the ship, and the opportunity to meet many people who work on the Lasker, including members of the science team, NOAA Corps, and Lasker crew.

The Night Shift

Running a ship like the Lasker is a 24-hour-a-day operation. At all times there are some groups of people sleeping and others who are working. The majority of the science crew works at night, so my day typically begins with dinner at 5:00 pm and then working with the science team from approximately 9:30 pm until 6:30 am. As a morning person this was very difficult at first! But after two nights working, I’m finally adjusting to our new schedule.

What is the Goal of the Survey?

The main scientific focus of the upcoming mission is the Rockfish Recruitment and Ecosystem Assessment Survey (RREAS). This survey has been conducted since 1983, and collects data on rockfish and other organisms in their ecosystem.

Rockfish are a very important fish commercially and recreationally in California and on the West Coast. One of the primary purposes of the survey is to use the data collected to helpย provide additionalย information about the management of commercialย and recreational fisheries off the west coast.ย 

CTD Operations

On the ship's deck at night, a man stands facing away from the camera, looking down a large apparatus nearly the height of his shoulder. Inside a round metal frame are gray cannisters arranged in a circle (the "rosette"), surrounding a scientific probe mounted in the center. A cable extends from the top of the appartus out of sight. The man wears a hard hat, a life vest, and sunglasses and grasps a gray rope looped through a rung of the rosette. Another man, also wearing life vest and hard hat, is seen at a distance beyond the apparatus. It's nighttime.
CTD rosette, ready to be deployed into the ocean.

I began my first night shift by observing a CTD deployment. CTDs are instruments that measure Conductivity, Temperature and Depth (CTD). CTD measurements are conducted approximately 5-6 times a day, and twice at night. The CTD descends down into the ocean to a depth of up to 500 m . There are other instruments and sensors attached to the CTD that measure things like chlorophyll levels and oxygen levels. The data taken from the water column serves as a foundation for scientists to understand the ocean environment.

All of the CTD data, and all the data that the Lasker collects, is free and available to the public.

Trawling

The lines are all labeled: we see the headrope (with buoys) at the top of the net, the footrope (small buoys) at the base of the opening, the bridle lines, door leg and transfer lines, the doors, and lines "to trawl winch" and net "to cod end."

When do we trawl?

The reason the science team trawls at night because there is net avoidance during the daytime, meaning the fish will see the net coming during the day and swim away from it. Other creatures migrate towards the surface at night. In a pattern called vertical migration, these mesopelagic species migrate to shallow waters to feed during the night, while spending day hours at depth.

Having more diverse species to study is useful for the Rockfish Recruitment and Ecosystem Assessment Survey (RREAS). The more data that is collected on rockfish and other species helps scientists to better understand the heath of different fish species, and make predictions and assessments of ocean trends.

How does trawling work?

Each night, the Lasker crew, NOAA corps officers, and science team work together to trawl for different fish species.

Trawls, which are nets towed behind a boat to collect organisms, have been used by fishers for centuries. Trawls can be divided into three categories based on where they sample the water column: surface, midwater, and bottom.” (NOAA Ocean Exploration)

In our Rockfish Recruitment and Ecosystem Assessment Survey, the science team conducts midwater trawls, at approximately 30m depth to target the fish and other ocean organisms that are targeted for the study.

The last few days we’ve averaged 5 trawls per night. The process begins by deploying the trawling net behind the ship into the midwater section of the water column, and trawling for fish for either 5 or 15 min. After the net is brought in, the contents of the trawl are sorted, measured, and recorded by the science team. This data will be later analyzed to help better understand the ocean ecosystem.

Charlotte stands at a large white bin, about three feet long, containing a pile of small silver-colored fish. She uses two hands to hold up a plastic pitcher filled with a sample of the fish - two other empty pitches rest in the bin. Charlotte wears a coat, orange grundens (fishing overalls), long orange gloves, and her Teacher at Sea beanie hat.

My new home for my time at sea is the NOAA Ship Reuben Lasker. The Lasker is a NOAA fisheries vessel, with a home port located in San Diego, CA.

The shipโ€™s primary objective is to support fish, marine mammal, seabird and turtle surveys off the U.S. West Coast and in the eastern tropical Pacific Ocean” (NOAA Office of Marine and Aviation Operations).

During my time at sea, the Lasker will be sailing off the coast of California, sailing out of Santa Cruz and back into port in San Diego.

Living on the ship reminds me a lot of my college dorm room. On the ship most people have roommates, and we all have shared spaces like the mess (cafeteria), science labs, outside decks and places to relax. Everyone aboard the ship has been extremely welcoming and kind, always answering any questions I might have and teaching me about life aboard a ship. I am happy to call the Lasker home over my trip at sea!

Did you know?

Adjusting to working the night shift (approximately 9:00 pm – 7:00 am) as a typical morning person has meant sleep is often on my mind. Chatting before our second night shift, scientist Ily Iglesias shared with me how dolphins sleep. Both dolphins and whales sleep much differently than most mammals. Known as unihemispheric sleep, dolphins

“only rest half of their brain while the other half stays awake to breathe. Also, most whale and dolphin respiratory and digestive tracts are completely separate, so they don’t get water in their lungs when feeding underwater.” (NOAA Fisheries).

Science and Technology Log

Without a vessel and without a crew, none of this mission would be possible. As Iโ€™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 Iโ€™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 Iโ€™ve discussed a lot of the daily operations of the crew and ship, and what Iโ€™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, โ€œWhat is NOAA?โ€ when I explain this opportunity.

The Vessel

NOAA Ship Bell M. Shimada, commissioned in 2010, is a fisheries survey vessel designed to produce a low acoustic signature, built to collect data on fish populations, conduct marine mammal and seabird surveys, and study marine ecosystems. The quiet operation provides scientists the ability to study fish and marine mammals without significantly altering their behavior.

Namesake

โ€œ[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.โ€

Wikipedia: โ€œNOAAS Bell M. Shimadaโ€

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.

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.

โ€œIn her remarks at the christening and launch, [Dr. Shimadaโ€™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.โ€

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. Iโ€™m so thankful I was able to have this experience and share NOAAโ€™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 canโ€™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 wayโ€ฆ

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.
