Science and Technology Log

On Wednesday night I stayed up to participate in the first CTD cast of the evening. What is a CTD? The short version: a water sample collection to measure conductivity, temperature, and depth. eDNA information is also collected during the CTD casts.

The longer version: As is true of all operations, all departments collaborate to get the science done. The bridge delayed casting due to erratic behavior from marine traffic in the area. When that vessel moved away, the deck crew got busy operating the crane that lowered the CTD unit to 500 meters. The Survey Technicians, along with the Electronics Technician, had just rebuilt the CTD unit days before, due to some hardware failures at sea. The eDNA scientist prepared the Chem Lab for receiving samples that would confirm the presence of hake as well as other species. 

When I arrived, Senior Survey Technician Elysha Agne was watching a live feed of the sensors on the CTD unit. Agne explained what was happening on the feed: There are two sensors per item being tested, then both sensors are compared for reliability of the data. There is one exception: A dual channel fluorometer, which gauges turbidity and fluorescence (which measures chlorophyll). Turbidity spikes toward the bottom in shallow areas due to wave action. Salinity is calculated by temperature and conductivity.  Sometimes there are salinity spikes at the surface, but it’s not usually “real data” if just one sensor spikes. The CTD unit is sent down to 500 meters as requested by scientists. Measurements and water collection occur at 500, 300, 150 and 50 meters. The number of CTDs allocated to a transect line varies according to how many nautical miles the line is. For example, multiple readings at the 500 meter mark may be taken on a line. CTD casts west of the one done at the 500m depth contour are spaced every 5 nm apart. Scientists are not currently taking CTD samples beyond the ocean bottom’s 1500m contour line.

The main “fish,” called an SBE 9plus, has calibrated internal pressure. As it descends you can tell the depth the “fish” is at. Sea-Bird Electronics (the origin of the SBE acronym) manufactures the majority of scientific sensors used on board, with the exception of meteorological sensors. The Seabird deck box (computer) is connected to the winch wire. The winch wire is terminated to a plug that is plugged into the main “fish.”

The other day, the termination failed. Termination means the winch wire is cut, threaded out, and the computer wire plugged into the winch wire. The spot it’s terminated can be exposed to damage if internal wires aren’t laid flat. Tension and tears may occur anyway because it’s a weak point. The plug on the main “fish” where the winch wire cable connects broke too, so the whole CTD had to be rebuilt. The “Chinese finger,” the metal spiral that pulls the load of the CTD on the winch wire, was also defective, so modifications were made.

The label touts: high dielectric strength, low volatility, moisture resistant, good thermal oxidation, etc. In the background, out of focus, we see someone working on the CTD unit.

The second is a yellow label that reads in large black print: "4127 meters maximum depth."
The main “fish” that the sensors are attached to..

When the CTD is at the target depth, Agne presses a button in the chem lab that logs a bunch of meteorological and location data. She remotely “fires” a bottle which sends a signal to the “cake” that sits on top of the CTD. The signal is an electric pulse to release a magnet that holds the niskin bottle open. If it pops correctly, water is sealed inside. Since two bottles of water were requested at each depth, a second signal is sent to the second bottle. There are 12 niskin bottles on the CTD “carousel.” After two were done at 500 m, the winch operator takes the CTD unit up to 300 m; Agne fires two more bottles there, then two more bottles at 200 m, 150 m, and 50 m. About two and a half liters of water are taken per bottle.

Samantha Engster, eDNA Scientist

Once the CTD unit returned to the surface, I got to help “pop the nipples” on the bottles to release the water into plastic bags. Back in the Chem Lab, eDNA Scientist, Samantha Engster, pours the water through a filter 1 micron thin. The filter is then folded in half and placed in a vial of Longmire’s solution until the eDNA can be analyzed in a lab back on land. Microscopes are not used for DNA analysis. Phenol-chloroform is used to remove proteins from nucleic acids. Quantitative polymerase chain reaction (qPCR) technique is then used to perform gene expression. This is the third hake survey that has been done in conjunction with eDNA analysis. 

While the CTD “fish” and all its sensors are collecting oceanographic data, Engster collects environmental data from the water samples. Surface water samples are also taken at the underway seawater station courtesy of a pump hooked up near one of the chem lab sinks. The eDNA verifies abundance and distribution of hake. When information from these water samples is partnered with data from the echo sounders, and “ground-truthed” with physical hake bodies in the net, the data set is strengthened by the diverse tests.

Evan McNeil & Evan Thomas, Engineers

Give us a brief job description of what you do on NOAA Ship Bell M. Shimada.

Evan M.
I’m a manager over our engineers. Below me is the second engineer. We have three third engineers, a junior engineer, and an oiler, also called a GVA (General Vessel Assistant), or wiper. I set the pace of work everyday. I assign all the jobs. Traditionally the Engine Department is under the First Engineer, but technically the Engine Room is mine. The Chief Engineer and the Captain (NOAA Corps Commanding Officer in this case) are in charge of the safety of the whole ship. The Chief Engineer also directs jobs to me that need to get done and I’ll delegate those jobs out. 

Evan T.
Third Assistant Engineer, soon to be Second. I mostly fix stuff that is broken.

What’s your educational background?

Evan M.
I have a Bachelor’s of Science in Marine Engineering Technology with a minor in marine science from California Maritime Academy. I grew up near Bodega Bay, so my background is oriented toward the ocean. I really enjoy it. 

Evan T.
Graduated from Cal Maritime, 2019. I grew up in Southern California, Redlands, a desert that somehow grows oranges. I applied to all the engineering schools in California, and Cal Maritime was one of the few that replied back. I said “Yeah, I could see myself doing this.” And here I am! 

What do you enjoy most about your work?

Evan M.
I enjoy who I work with. It makes work go by quickly. I enjoy our schedule and our time off. This is what I enjoy about my NOAA job and about sailing jobs in general. Shore leave is a type of leave. There’s also annual leave and sick leave. We call it going on rotation or off rotation. Off rotation is usually for a month, and on rotation is usually two months. Every ship is different but that’s how it is for the Shimada, a two-on, one-off schedule. If you talk to other sailors they’ll tell you ratios for time on and time off. For example, I did Leg 2 of the hake survey, I’m on Leg 3, and then I’m off. 

Evan T. Learning new equipment, new ways to do things.

What advice do you have for a young person interested in ocean-related careers?

Evan M.
If you are interested in going straight to being an officer, I would go straight to a maritime academy. It’s a very niche thing to know about. No one knows what they want to do at 19. NOAA’s always hiring. If you are interested in being an engineer, you start out as a wiper, then you can work your way up in the engineering department pretty easily.  

Evan T. 
Imagine being stuck in an office and you can’t go home for a month. Find something that will distract you when you are out on the ocean for weeks at a time. Hang out with people, play games, read a book. You have to be ready to fight fires, flooding, that sort of thing. 

If you could invent a tool to make your work more efficient—cost is no concern, and the tool wouldn’t eliminate your job—what would it be and why?

Evan M.

Evan T.
I would go for an elevator on the ship.

Do you have a favorite book?

Evan M.
Modern Marine Engineering volume 1

Evan T. My 5th grade teacher wrote their own book that I found entertaining. I also liked Huckleberry Finn, by Mark Twain.

Vince Welton, Electronics Technician

Vince Welton

Give us a brief job description of what you do on NOAA Ship Bell M. Shimada.

I’m an electronic technician. I deal with everything that has to do with electronics, which includes: weather, navigation, radars, satellite communications, phone systems, computers, networking, and science equipment. All the ancillary stuff that doesn’t have to do with power or steering. Power and steering belongs to the engineers.

What’s your educational background?

When I was in high school my father had an electronics shop and I worked with him. He was career Air Force and an electronics technician as well. My senior year of high school  I was also taking night classes at a college in Roseburg, Oregon in electronics. I joined the U.S. Air Force and was sent off to tech school and a year’s worth of education in electronics. Then there was a lot of learning on the job in electronic warfare. I worked on B52s. I was a jammer. In order to learn that you had to learn everybody else’s job. That’s what makes mine so unique. You had to learn radio, satellite, early warning radar, site-to-site radar, learning what other people did so I could fix what was wrong with their electronic tools. I went from preparing for war to saving the whales, so to speak. Saving the whales is better!

What do you enjoy most about your work?

I enjoy the difficulty of the problems. We’re problem solvers.

What are the challenges of your work?

Problems you can’t fix! That’s what disturbs a technician the most, not being able to solve a problem. 

What advice do you have for a young person interested in ocean-related careers?

The sciences are important no matter what you do. Having curiosity is the biggest thing. My hope is that education systems are realizing the importance of teaching kids how to think. Young people need to grow the ability to ask questions, instead of just providing answers.

If you could invent a tool to make your work more efficient—cost is no concern, and the tool wouldn’t eliminate your job—what would it be and why?

I think AI has phenomenal potential, but it’s a double-edged sword because there’s a dark side to it as well.

Do you have a favorite book?

The Infinity Concerto, by Greg Bear
The Little Book of String Theory, by Steven S. Gubser

What’s the coolest thing you’ve seen at sea?

Actually seeing a whale come out of the water is probably the coolest thing. Watching that enormous tonnage jumping completely out of the ocean. If you look out the window long enough and you’ll see quite a few things.

Markee Meggs

Give us a brief job description of what you do on NOAA Ship Bell M. Shimada.

I’m an AB, or Able Bodied Seaman. The job looks different on different ships. On the Shimada I stand watch and look for things that don’t show up on radar. Most ships you drive—only NOAA Corps Officers drive on the Shimada—I can drive rescue boats, tie up the ship, and do maintenance on the outside. I’m a crane operator. On a container ship you make sure the refrigerated containers are fully plugged in. On a refueling ship (tanker) you hookup fuel hoses. Crowley is a major tanker company. On RoRo ships (roll on, roll off) you work with ramps for the vehicle decks, transporting cars from overseas.

AB is a big job on a cruise ship. I did one trip per year for three years, then got stuck on one during the pandemic in 2020.  On the cruise ship you stand watch, do maintenance, paint, tie up the ship, drive the ship. There’s even “pool watch” where you do swimming pool maintenance. You also assist with driving small boats and help guests on and off during a port call.

I’m a member of SIU (Seafarers International Union) and work as an independent contractor for NOAA. I like the freedom of choosing where I go.

What’s your educational background?

I’m from Mobile, Alabama. I spent four years in the Navy (my grandad served on submarines during World War Two), one year in active Navy Reserves, then eight years as a contractor supporting the Navy with the Military Sealift Command. I spent a year as a crane operator in an oceaneering oil field, and have an Associate’s Degree in electrical engineering. On the oil field job we used an ROV to scope out the ocean floor first. After identifying a stable location I laid pipe with the crane, and took care not to tip over the boat in the process! My first NOAA ship  was the Rainier, sailing in American Samoa. 

What do you enjoy most about your work?

I most enjoy meeting different types of people. Once you’ve been to a place you have friends everywhere. I also love to travel—seeing different places. It’s a two-for-one deal because once you’ve finished with the work you are in an amazing vacation place.

What advice do you have for a young person interested in ocean-related careers?

If ships interest you, do the Navy first. They pay for training, and your job is convertible. Becoming a merchant mariner is easier with Navy experience than coming straight off the street. There is a shortcut to becoming a merchant mariner, but you’ll have to pay for classes. Finally, always ask questions! Yes, even ask questions of your superiors in the Navy. 

What’s the coolest thing you’ve seen at sea?

The coolest things I’ve seen at sea have been the northern lights in Alaska, whales, volcanic activity, and rainbow-wearing waterfalls in Hawaii.

Do you have a favorite book?

Some of my favorite books are Gifted Hands, and Think Big, both by Ben Carson. Gifted Hands: The Ben Carson Story was turned into a film with Cuba Gooding Jr in 2009. Another book that made an impression was Mastery, by Robert Greene. Its overarching message is “whatever you do, do well.”

Julia Clemons, FEAT Team Lead

Julia Clemons

Give us a brief job description of what you do on NOAA Ship Bell M. Shimada.

I am the Team Lead of the FEAT (Fisheries Engineering and Acoustic Technologies) Team with the NWFSC (Northwest Fisheries Science Center). The primary mission of our team is to conduct a Pacific hake biomass survey in the California Current ecosystem and the FEAT team was born specifically to take on that mission from another science center. The results of this survey go into the stock assessment for managing the fishery. Fisheries and Oceans Canada are partners in this survey. Hake takes you down many paths because their diet and habitat are tied to other species. For example, krill are a major prey item in the diet of hake, so understanding krill biomass and distribution is important to the hake story as well. Rockfish also have an affinity for a similar habitat to hake in rockier areas near the shelf break, so we use acoustics and trawling to distinguish between the two. 

What’s your educational background?

My undergraduate degree from University of Washington was in geological oceanography. I began with NOAA in 1993 and worked for the Pacific Marine Environmental Laboratory’s Vents program to study hydrothermal systems. This involved a diverse team of scientists: chemical and physical oceanographers, biologists, and geologists. I got my Master’s in Geology at Vanderbilt but shifted to NOAA Fisheries in 2000 working in the Habitat Conservation and Engineering (HCE) Program where we looked at habitat associations of rockfish. We looked at ROV and submersible video of the rocky banks off Oregon to identify fish and their geological surroundings. The HCE program shifted its focus to reducing bycatch by experimenting with net modifications and I moved to the FEAT team.

What do you enjoy most about your work?

I think one of the most important components of Team Lead is to be a supporter—supporting the facilitation of good science, supporting people. I also think about what I can do to support the overall mission of NOAA Fisheries. That’s my favorite thing, supporting others. I love when the focus is not on me!

What advice do you have for a young person interested in ocean-related careers?

Think about ways you can put yourself in the right place at the right time. Ask about volunteer opportunities. Ask questions, explore, think about what you want to do and look at people who are doing that—ask them how they got to that position. 

What’s the coolest thing you’ve seen at sea?

When I was with the NOAA Vents group in 1994 I got to go to the bottom of the seafloor in the submersible Alvin. I was in there for nine hours with one other scientist and Alvin’s pilot. You think you’re going to know what it looks like, because you’ve seen video, and you think you’re going to understand how it feels, but then you get down there and everything is bigger, more beautiful, in all its variation and glory. We navigated to a mid-ocean ridge system that had an eruption the year previously. There was bright yellow sulfur discharge on black basalt rocks… after all those hours looking at ROV video, to see it in person through the porthole was incredible.

Do you have a favorite book?

The 5 AM Club, by Robin Sharma. I’m a morning person, and this book lays out how to structure those early hours and set you up for a successful day. When I was little I loved The Little Mermaid story by Hans Christian Anderson—the original, not the Disney version. I grew up in Vancouver, Washington and was always asking my parents, “Can we go to the beach?”

Taxonomy of Sights

Day 11. Three lampreys in the bycatch! Risso’s Dolphin (Grampus griseus).
Day 12. Blue Whales! I guess they read my blog post about the Gordon Lightfoot song. What may have been a blue shark came up near the surface, next to the ship. Strange creatures from the deep in the bycatch: gremlin looking grenadier fish.
Day 13. Pod of porpoises seen during marine mammal watch.

You Might Be Wondering…

How often are safety drills?

Weekly drills keep all aboard well-practiced on what to do in case of fire, man overboard, or abandon ship. Daily meetings of department heads also address safety. One activity of monthly safety meetings is to review stories of safety failures on other ships to learn from those mistakes. Each time a member of NOAA Corps is assigned a new tour at sea they must complete a Survival-at-Sea course. The Fishery Resource Analysis and Monitoring division (FRAM) also requires yearly Sea Safety Training for the scientists. “Ditch Kits,” found throughout the ship, contain: a rescue whistle, leatherman, food rations & water, and emergency blankets. Additionally, there are multiple navigation and communication tools in the ditch kit: a traditional compass, a handheld Garmin GPS, a boat-assigned PLB (personal locator beacon) registered with the Coast Guard, and a VHF radio with battery backup providing access to marine channel 16.   

After a tour of the engine rooms, I learned that the diesel engines also have built in Emergency Diesel Generators (EDG). If you look up at the lights on the mess deck you’ll see some of the light fixtures have a red and white “E” next to them. This label indicates which would be powered by the generators, and which would not.

Floating Facts

The NOAA Corps is not a part of a union, however there are unions that advocate for other NOAA employees. Licensed engineers are a part of MEBA, The Marine Engineers’ Beneficial Association. Non-licensed positions are represented by SIU, Seafarers International Union. Both of these unions are a part of AFL-CIO, the largest federation of unions in the U.S.

I had been curious whether there was a database that housed an inclusive list of NOAA Fisheries field research, and NOAA did not disappoint. You can find the Fishery-Independent Surveys System (FINNS) here, and browse as a guest. I’m now brainstorming how I might use the database with students—perhaps as a scavenger hunt—to have them practice their search skills. You can search by: fiscal year, fiscal quarter, science center, survey status, and platform type. 

Which Cook Inlet species is the subject of Alaska Fisheries Science Center (AFSC) 2023 research, which is underway in a small boat?
Hint: Raffi 

Another tool I’m looking forward to using in the classroom is NOAA’s Species Directory, which can serve as a scientifically sound encyclopedia for ocean animal reports conducted by students.

Librarian at Sea

“The sea is a desert of waves,
A wilderness of water.”― Langston Hughes, Selected Poems

This quote from Hughes’ poem, Long Trip, had me thinking about the surface of the ocean. I have seen the surface in many states over the past days: soft folds, jagged white-tipped peaks, teal, turquoise, indigo. Sometimes there are long snaking paths of water that have an entirely different surface than water adjacent. Whether it is due to currents colliding, chemical process, biological process, temperature difference—I cannot say. If I were to anthropomorphize the phenomena, I’d say these lines are wrinkles, as the ocean creases into different expressions. A hint of what lies within and beneath.

It also has me thinking about the interviews I’ve conducted with the people on NOAA Ship Bell M. Shimada. I started with a superficial name and title, a face on a board near the Acoustics Lab depicting all hands on Leg 3. When I sat down to talk with people representing Scientists, Engineers, Deck Crew, Electronics, Officers, Survey, and Steward, I began to unspool colorful stories from a broad spectrum of life experiences, many from divergent habitats, all who have converged here to do in essence what the concierge at my Newport hotel said to me as I walked out the door, “Keep our oceans safe!” A tall order in so few words. From shore we’re a small white blip on the horizon; up close there’s a frenzy of activity, a range of expertise, a conviction that our actions can improve living for humans, for hake, and for all the species in Earth’s collective ecosystem.

Hook, Line, and Thinker

We opened up a hake in the Wet Lab today to find it had a green liver. Why? Parasites? A bacterial infection? An allergy to krill? There’s always more beneath the surface, more stories to suss out. This is what makes science exciting, what makes living with 30+ strangers exciting. It’s what I enjoy about teaching. 

How do the albatross know when we’re hauling back a net full of hake? They seem to appear out of nowhere. First a couple, then maybe 40 of them materialize around the net, squabbling over fish bits. 

Have you ever discovered something unexpected and wondered about its origins?
How could the scientific method support you in finding out an answer… or to at least develop a theory?

A Bobbing Bibliography

Known as “charts” at sea and “maps” on land, NOAA Ship Bell M. Shimada has a small library of charts. Find out more at NOAA’s Office of Coast Survey. Paper charts are actually being phased out. “NOAA has already started to cancel individual charts and will shut down all production and maintenance of traditional paper nautical charts and the associated raster chart products and services by January 2025.”

Science and Technology Log

Hake are not the only thing being studied during this mission. In the Chemistry Lab, there are a variety of ongoing tests. Every few transects, seawater is collected and tested for Harmful Algal Bloom (HABs). A vacuum pump sucks the sample through a 0.45um filter, which is then removed and placed into a test tube for microscopic study. The Southern California coast is currently dealing with a bloom toxic to animals. Scientists want to know if the bloom is drifting north. Blooms are a natural phenomenon, but human activity cannot be ruled out from having an impact.

A seawater pump connects to a software program that allows you to see images of phytoplankton being photographed in real time as they are sucked past the camera. Phytoplankton forms the base of the aquatic food web. They provide food for huge whales, small fish, invertebrates, and zooplankton. Plankton makes up 95% of life in the ocean, they generate half of our oxygen and absorb carbon. A sudden removal of phytoplankton would result in a collapse of aquatic ecosystems, and would accelerate climate change further.

The phytoplankton images are taken using a robotic microscope automating identification. The name of the artificial intelligence is Imaging Flow CytoBot (IFCB). Flow cytometry uses lasers to create both scattered and fluorescent light signals. These signals are read by photosensitive diodes and tubes, and then those signals can be converted electronically to be read by a computer. The data gathered enables ecosystem modeling, and can act as an early warning to toxic blooms.

Chief Scientist, Steve de Blois, on the bridge during a trawl.

Steve de Blois, Chief Scientist

Steve’s favorite thing about his job is getting out in nature, seeing, and photographing marine mammals. Even though the hours are long, the commute is short when you’re at sea! His educational background includes an undergraduate degree in biology from the University of Michigan, Ann Arbor; and a Master’s from Humboldt State University (now called Cal Poly Humboldt) in marine mammals. It was tough finding work after graduate school since working with marine mammals generally holds more appeal than fish, and thus more people are competing for a finite number of jobs. Once Steve secured a job at one of NOAA’s regional offices, he found out about other opportunities and ended up on a walleye pollock acoustic trawl survey in Alaska. This is where he had one of those National Geographic moments where the scenery is so stunning it touches you at your core. He has been with NOAA since 1990—the same year the Teacher at Sea Program began. 

Steve’s advice for young people interested in ocean-related careers is to focus on getting your education. He states that getting a graduate degree (PhD and/or Master’s) will make you more competitive in the scientific community. However, he also advises, “get experience.” Nothing can compare to first-hand experience and there are many opportunities for volunteering in the field, in marine labs, and on ships.

During his leisure time, Steve prefers to fly his home-built plane (A Zenith CH 650), go scuba diving, and enjoy photography. When it comes to reading he prefers nonfiction. He has German heritage on his mother’s side and shared some personal history of family members surviving both World War One and World War Two. This part of his family tree has increased his interest in true tales about World War Two German fighter pilots. In his youth, he absorbed science fiction novels by Arthur C. Clarke and recalls enjoying Dune, by Frank Herbert. Recently, he read Rachel Carson’s classic The Sea Around Us and was impressed by its lyrical prose.

Steve has patiently taught me about how to detect hake sign on an echogram. Acoustically speaking, hake have a unique characteristic. The visualized pings usually show hake near the slope of the continental shelf, and they appear as a diffuse cloud of colored pixels, or as a “hakey snakey” line gently curving up and down.  A calculation called NASC, Nautical Area Scattering Coefficient, makes an estimate of individuals in that defined area drawn by scientists.

The acoustic echogram has a color key representing the strength of return on what the sound waves bounce off. The color scale looks something like you’d see in an art room class teaching color theory. The weakest return is signified by a pale grey to dark, then a light blue shade into dark, the blue turns teal as it morphs into greens, then when yellow appears the scientists start getting excited. After yellow is orange, pink, then many shades of red ending with a deep magenta. The ocean floor appears as deep magenta. On Leg 2 the Shimada saw several very dense balls of fish; these fish are likely herring or sardines, species smaller than hake.  The acoustic return from these very dense balls of fish is extremely high—their color in the acoustic software is easily deep red, almost brown.

The thicker reddish brown line you see is the continental shelf/ocean floor. The greenish-yellow cloud represents an acoustic signature historically found to be hake. The thin red lines in the echograms on the right represent the head rope from imaging by the SBE (Sea-Bird Electronics) camera, aka “the turtle.”

Taxonomy of Sights

Day 5. Bycatch highlights: Intact squid, Chinook salmon (also known as King salmon), and excited albatross following a record haul.

Day 6. More salmon, two kinds of rockfish, a Thetys vagina salp (more on the awkward name here), and a marine hatchetfish so small my camera found it difficult to focus on. Ethan Beyer, Wet Lab Lead, shared a trick to determine the difference between a yellowtail rockfish and widow rockfish (they look similar). The difference? Widow rockfish have a “widdle” mouth. Meaning, the mouth is smaller than the yellowtail’s (ha, ha). The two types of rockfish we caught were the widow and the shortbelly (Ethan says they make great tacos!) Speaking of tacos, the widow rockfish are due to make an appearance on our mess deck menu soon. 

Day 7. Not much…

You Might Be Wondering…

What is the furthest you’ve been from shore?
To date (July 28th), an extension of transect 39 took us a total of 62 nautical miles from shore, which beat our extension record on Wednesday, July 26th. Leg 3 has extended more transects than Leg 2. The reason for extending a transect is to go where the fish sign is. The NOAA Fisheries protocol is to discover what the western extent is for schools of hake on that transect. So, they wait for at least one mile without seeing hake before ending the transect.

What is the deepest trawl you’ve made?
So far on Leg 3 we’ve gone 400 meters (about a quarter of a mile) to reach a target depth. Simply put, target depth is where the fish are estimated to be.

Floating Facts

Vocabulary

Bycatch – Some dictionaries call them unwanted creatures caught in the pursuit of a different species. NOAA however, thinks it worthwhile to catalog the biomass of these tag-alongs.

Biomass – The total weight (sometimes quantity) of a species in a given area or given volume.

One of these things is not like the others
Tow, Haul, and Trawl are used interchangeably in reference to fishing.
“Catch” is what we’ve caught in the net.

Survey Permits

You know how you ask permission at school and at home to do a thing? The hake survey requires a number of permits to conduct its research. A permit is an official document saying you have asked for and been granted permission. 

NOAA’s Western Region office issues “Authorizations and Permits for Protected Species.” The protected species are salmon and eulachon, a thin silvery thing about the size of a herring. The permit dictates what you can (measure and weigh it) and can’t do (eat it) with protected species.

A state’s jurisdiction over ocean waters only extends three nautical miles from shore. The Oregon Department of Fish and Wildlife wants to know the number of all species caught off its coast. California’s Department of Fish and Wildlife issues a Memorandum of Understanding (MOU) along with a permit. The MOU calls out particular species they are interested in: longfin smelt, coho and chinook salmon. 

Jenny stands in the wet lab holding a sizable salmon with two hands. She wears black gloves, black overalls, and a Teacher at Sea beanie.
I should be frowning – we don’t intend to be pulling salmon out of the water. However, their appearance does contribute to data about the health of their populations.

While fishing rarely ever happens in Alaskan waters during the hake survey, the Department of Fish and Game issues a permit that is shared with Canadian colleagues who may pursue hake further north. Waters defined by NOAA’s National Marine Sanctuaries have their own monitoring system and permit issuance. The hake survey passes through three sanctuaries in California waters and one in Washington (the Olympic Coast). Finally, the West Coast Region of NMFS (National Marine Fisheries Service) issues a permit and requires a record of all species caught in U.S. waters, so a grand total of sorts for all states involved. 

Personal Log

Thursday was a huge improvement over the icky Wednesday ride. We made two successful trawls, and two trawls on Friday. Wet Lab Lead, Ethan Beyer, commented during fish processing on Friday, “I feel like I’m the world’s foremost expert on the visual maturity of hake. I look at a lot of hake gonads.” This was memorable.

Saturday dawned with too much fishing line in the water to do anything so we waited until we moved past it before dipping the net in. We did squeeze in a catch before lunch, but it produced exactly one hake among the usual lanternfish and pyrosomes. Disappointing for the science crew.

Note: In an earlier post I referred to lanternfish as “lampfish,” which is incorrect. I’ve also been calling Dramamine “dopamine” for some reason. I’ll blame it on the mild disorientation that is caused by floating around on the ocean.

My Daily Routine

I wake around 0600 and sometimes make it up to the flying bridge to see the sunrise, but usually go up regardless before breakfast to view the morning light. I stop in at the acoustics lab to sit at my workstation, blog a bit, and see what hake sign there is on the echogram (software visualization of what lies beneath us). Breakfast is served at 0700, then I return to acoustics to stay up to date on when we’re going fishing.

When you hear, “Fishing, fishing, fishing,” on the radio you know it’s almost time for the marine mammal watch. Marine mammal watch happens on the bridge, and I continue watching for a while even after the watch ends. I’ll stay up there for most of the trawl until I hear, ”Doors at the surface.” (More on the stages of a trawl next time.)

Next, I’ll go to the “ready room” in the wet lab where boots and fishy rubber overalls are stored. Blog post three walked you through what we do in the Wet Lab once the catch has been dumped in the crate. Processing species takes us into lunch hour at 1100.

A second trawl after lunch, and assuming the catch is decent, processing will take us to dinner. I have down time after dinner, watch the evening light if the weather is amenable, then return to acoustics for more blog time. I’m in bed somewhere between 2030 and 2230.

While there is a general routine, no day is exactly alike. On Saturday I assisted Ethan with collecting sea water from a vertical net dipped by a crane to 100 meters. Scientists will look at the plankton, krill, and other small species to determine stratification and measure abundance.

“It is a curious situation that the sea, from which life first arose should now be threatened by the activities of one form of that life. But the sea, though changed in a sinister way, will continue to exist; the threat is rather to life itself.”― Rachel Carson, The Sea Around Us

The cover of Rachel Carson’s book, The Sea Around Us, appears on the wall of the dining room at Sylvia Beach Hotel where I stayed prior to the departure of leg three. Her poetic approach to scientific insight continues to inspire readers. The book I brought with me on the ship does something similar. In How Far the Light Reaches, author Sabrina Imbler blends personal memoir with profiles of ten sea creatures. Imbler attempts to keep metaphors and personal (human) parallels at a distance from the scientific integrity of species. Both titles are recommended reading.

Hook, Line, and Thinker

When I was a kid, my Dad sometimes sang Gordon Lightfoot’s ‘Ode to Big Blue’ as a lullaby before bed. It’s one of the only songs I know all the lyrics to, although sometimes I scramble the verses up. I think it was my first exposure to the tension between commerce and the sustainability of natural resources. The sixth verse says,

Now the gray whale is run and the sperm is almost done
The finbacks and the Greenland rights have all passed and gone
They’ve been taken by the men for the money they could spend
And the killing never ends it just goes on

Herein lies another ethical debate on balancing preservation, economics, and the needs and wants of Homo sapiens. The song celebrates the natural wonder of whales alongside the biting reality of human enterprise.

In April 2023 NOAA released a 2022 Status of Stocks report. Data displayed overfishing status of 490+ stocks managed by NOAA. 

a NOAA Fisheries infographic showing two pie graphs in the shape of fish silhouettes. the first is labeled 355 Stocks with Known Overfishing Status. This graph shows that 93% are not subject to overfishing (331 stocks) while 7% (just the tip of the tail of this snapper-shaped fish) are subject to overfishing (24 stocks). The other graph is labeled 249 Stocks with Known Overfishing Status. It shows that 81% are not overfished (201 stocks) while 19% (a little more than the tail of this tuna-shaped fish) are overfished (48 stocks).



NOAA Fisheries assistant administrator, Janet Coit, said in the Status of Stocks news release, “Managing fisheries sustainably is an adaptive process, relying on sound science and innovation to conserve species and habitat, and meet the challenge of increasing our nation’s seafood supply in the face of climate change.” NOAA Fisheries priorities for fiscal year 2023 are full of words like: sustainability, resilience, mitigate, adapt, diversify, ensure equity, safeguard, propel recovery, conservation, protect, and restore. NOAA continuously strives to balance the scales between conservation and consumption.

What are the ethical concerns that should guide economics?
Is it possible to view the ocean other than as a natural resource?
Is that view in fact imperative to the sustainability of life on Earth?

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.

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).

“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.

Mission: Pacific hake (Merluccius productus) Survey (Leg 3 of 4)
Geographic Area of Cruise: Pacific Ocean off the coast of Newport, Oregon
Date: July 19, 2023 (pre-cruise)

Weather Data from Newport, Oregon
NOAA Weather Service forecast for Wednesday, July 19th as of 7/17/23 6:35pm:
Mostly sunny, then sunny and breezy, with a high of 61 degrees. Wednesday night’s low around 55 degrees.

“Weather” is what it’s doing today. “Climate” is what it did today in 1942. Climate equates to the prevailing weather trends for a particular region. Having been born and raised in Oregon I know that you always dress in layers when going to the Oregon Coast. I know that sunburn is possible in March (anytime really) and balmy 60-degree weather is possible in February. Historically, the average temperature for the month of July in Lincoln County has remained between 60 and 63 degrees with a slight trend upward. I imagine it is a bit chillier out on the Pacific. I have packed accordingly!

A week from departure (July 16th) I was looking south from the cliffs on Cape Lookout near Tillamook, Oregon. The breeze was visible in shimmering white flashes across the surface of the ocean even as the tidal swells plowed steadily into shore beneath the gusts. The infamous summer fog shrouded much of the cape’s seaward view due to temperature and pressure differences between the coast and inland.

view of Cape Lookout from the cliffs. Beyond dirt cliffside and conifer trees, we can see the water is a vivid blue-teal color. A mountain range marks the far side of the cape. The sky is blue, but fog rises off the water.

As air heats up it ascends (rises), leading to low pressure at the earth’s surface. As air cools down it descends (sinks), leading to high pressure at the surface. Hot summer air rises inland and creates low pressure. Since the temperature of the ocean is much colder, high atmospheric pressure is formed. Higher-pressure air tends to move into lower-pressure regions, so the moist marine layer (caused by evaporation) gets pulled off the top layer of the water and moves inland. All that moisture creates low-flying clouds, known as “fog” when it touches the ground. Marine fog moves eastward (inland) and usually clings to the shoreline. Sometimes it moves further depending on the topography of the coast range. Summer winds on the Oregon Coast are caused by temperature-driven atmospheric pressure disturbances where the two pressure systems collide.

Listening to the weather forecast was something of a ritual in my childhood home. Mom would tune in to WKL96 at 162.475 and we’d dutifully hush up when the familiar “ding!” occurred to signal the top of the broadcast. To this day she still writes down the short-term forecast and puts it on the fridge. (Mom is an old-fashioned gal and doesn’t use the internet.) Find your local station here.

I got to tour my local National Weather Service office –home of the “ding!”– in Portland, Oregon during a DataStreme Climate class I took in 2016. Sponsored by the American Meteorological Society, I also took their DataStreme Oceans course. I highly recommend these classes to educators.

I’m a bit of a NOAA snob when it comes to the forecast. My old Subaru had a channel entirely devoted to NOAA Weather Radio. My new (used) one doesn’t, and I miss it! Friends and family look at a variety of weather apps, but I will always check their predictions against what NOAA says. When you visit National Park Visitor Centers around the country it’s usually the short-term NOAA forecast that is posted on visitor information boards. It is possible to access NOAA Weather from your phone. Go to the following website to learn how to add a bookmark to your phone’s home screen.

Librarian at Sea

“Traditionally, a few people from Raftworld would decide to stay on the island; and a few from the Islands would elect to join Raftworld. These were volunteers, and they were celebrated for their choosing, for some people were simply happier living on land, and others happier at sea.” 
~H. M. Bouwman, A Crack in the Sea
(G.P. Putnam, 2017)

A Crack in the Sea is a middle-grade novel that blends fantasy with historical fiction, including characters who flee a slave ship, and those fleeing post-war Vietnam. One character also has a special skill: talking to fish. My special skill is talking to children about books…but I do much more than that. 

Introduction & Background

I have reported to 551.46 many times over my 18 years as a school librarian, but this will be my first reporting to its physical manifestation. Despite growing up near the coast I have never been out on the open ocean in a boat. I have visited the nonfiction shelves (organized by Melvil Dewey) countless times. You’ll find oceanography topics at 551.46. You’ll find my school, Peninsula Elementary, on an earthen finger of Portland, Oregon bordered by the Willamette River to the west and the mighty Columbia River to the north. Peninsula has been my anchor as an educator for the past 12 years. I call myself a “teacher librarian” in order to emphasize that my priority is to design and deliver lessons to students on top of managing a small library. My profession has state and national standards that cover information literacy, reading engagement, and social responsibility. One of the things I love most about being a school librarian is the academic freedom that I have. I can teach my standards by using the story of the haenyo mermaids of Korea, by analyzing infographics of the water cycle, and by playing truth or lie with shark facts. Cross-curricular approaches to learning are what get me excited about teaching. Science in particular is a subject I have long gravitated towards. 

My career in a, er, clamshell: As an undergraduate with a BA in Comparative Literature I said, what next? I promptly got a seasonal job as a Ranger Aide for Silver Falls State Park. What next? I applied to permanent ranger jobs…and my old school district (where I graduated high school) was looking for a school librarian. My alma mater hired me with zero experience on a restricted transitional license–which means I promised to go back to school and get certified. So, I got my teaching license, then a Master’s in Library Science–two distinct programs. While in graduate school I began branding myself as a “Ranger Librarian.” While working for the same junior high I once attended, I had the odd experience of working with colleagues who were formerly my teachers. A beloved high school social studies teacher still worked next door on our shared campus. He encouraged me to seek out opportunities for educators that provided residencies, travel opportunities, and hands-on learning. So, when I saw a brochure in the staff lounge for an Outward Bound course designed just for teachers I applied. What next? I applied for a Cultural Resources Internship at Grand Teton National Park where, among other things, I created an information package for prospective researchers to help them navigate the application process and eliminate research redundancy. I learned, for example, there is such a thing as collecting too many voles. I applied for a “Teacher Ranger Teacher” position at Grand Canyon National Park. I applied to be a seasonal ranger again, this time in the Columbia River Gorge. I applied for a Comparative Mountain Geography Institute with the Center for Geography Education in Oregon. I did all those things in the margins of my life as a teacher librarian. What next? I applied to be a NOAA Teacher at Sea! 

As the others in NOAA TAS Class of 2022 and 2023 will confirm, I then played the pandemic waiting game while the world figured out how to function with COVID. TAS candidates have to pass a medical clearance within a year of sailing so I even gave blood not once, but twice, while time and tide marched on. I have yet to sweat, and yet to cry, but the salt swims at the ready.

Science, Technology & Career Log
You can track the location of NOAA Ship Bell M. Shimada as well as other vessels here.  Alternatively, you can try this tracker.  Marine traffic includes all ships at sea such as tankers, military vessels, passenger ships, and fishing boats. An automatic identification system, or AIS technology, is used to follow traffic locations. The International Maritime Organization (a branch of the United Nations) launched the development of AIS as a collision avoidance tool for large vessels at sea that were not within range of tracking systems based on shore.

The IMO decided that all vessels over 300 gross tonnages on international voyages must have AIS aboard. A gross tonnage is calculated by measuring a ship’s volume. AIS allows ships to “see” each other and improves situational awareness before visual contact is possible. AIS is considered by some to be the most significant improvement to navigational safety since the development of radar. However, AIS is considered an enhancement and not a replacement for radar and other traffic services. Using a broadcast transponder system, AIS operates in the VHF (very high frequency) radio waves mobile maritime band. A complete system includes a transmitter and a receiver with data displayed on a screen (revealing the bearing and distance of nearby vessels). Originally, AIS made broadcasts from ships to land and had a capacity of 20 miles or so. Today, satellite-detected AIS allows us to “see” ships no matter how far away.

Radio waves are one type of electromagnetic radiation–in the same family as X-rays, visible light, microwaves, infrared, and ultraviolet. Naturally occurring radio waves include lightning and objects in space including Jupiter and The Sun. It is possible to turn information like text, sound, and images into electrical signals. These signals are combined with radio waves–energy that moves–to send information across long distances. High-frequency waves have a shorter wavelength and send more wavelengths per second than low-frequency waves. In general, higher frequencies do not travel as far, which is why satellites have proven so useful to AIS. (Further reading)

Career feature

I am excited to meet all the people behind the research and ship operations. Prior to sailing, I checked out the professional mariner hiring portal facilitated by NOAA’s Office of Marine and Aviation Operations.  Current fleet vacancies included able seaman, oiler, and first assistant engineer. Reading the job descriptions brought to mind two things. One is my maternal grandfather. He was a World War Two Navy Veteran who worked as a motor machinist and drove a Higgins Boat on D-Day during the invasion of Normandy. He did not die in the war, but lived to age 89 and passed away in 2012. Among the family archives are records of his completion of a diesel mechanics course. This association made me think about encouraging students to make personal connections to whatever we are learning about.  After reminiscing about Grandpa, my train of thought spitballed keywords like boat, engine, ship, sailor, mechanic, and Titanic–which served as a bridge to thought number two. The fleet vacancies prompted a daydream about the next time I am helping a student interested in library books on one of these tangential ocean topics. In addition to a forthcoming lesson on NOAA careers, I should remember to mention a related career during book shopping and plant a seed. “Hey Johnny, I see you are interested in ships. Did you know that being a sailor is an actual job that you could do one day?”

NOAA Fisheries has its own job opening portal. Openings at the time of my website visit included a statistician, IT Specialist (systems administrators are needed everywhere!), fish biologist, physical science technician, grants management specialist, budget analyst, enforcement technician, and acquisition management specialist. Fish biologist was an obvious choice but I had to click on enforcement technician to find out more. It appears to be an entry-level position related to NOAA’s Office of Law Enforcement (see video insert).  

Holy mackerel, this initial career investigation blew my mind with how many employment opportunities there are within NOAA. I think my students will be impressed with the broad scope of career choices as well. 

Floating Facts

NOAA Ship Bell M. Shimada (in service since 2010) serves the entire West Coast and furthers the NOAA Fisheries mission to be “responsible for the stewardship of the nation’s ocean resources and their habitat.” The imperative of NOAA Fisheries is to maintain healthy ecosystems, safe sources of seafood, productive and sustainable fisheries, as well as the recovery and conservation of protected resources. NOAA’s parent agency is the U. S. Department of Commerce and so relates to economic growth and opportunity. Bell M. Shimada is known as a “quiet” ship, using technology to decrease its noise signature and increase scientists’ abilities to study fish without disturbing them. 

Bell M. Shimada, the man, was known for his studies of Pacific tuna stocks important to the development of commercial fisheries post-World War Two.  His name was chosen by a group of California high school students in a contest to name a new ship in the NOAA fleet. Born to Japanese immigrants in Seattle, Washington, he was imprisoned at Minidoka War Relocation Center in 1942 during the mass internment of Americans with Japanese ancestry. He was 20 years old at the time. He was able to leave the camp by enlisting in the U. S. Army. Shimada began as an infantryman, then an interpreter, translator, and radio traffic monitor, then compiled data on the impact of bombings in Japan. He ended up in Tokyo during its occupation and remained after the war in a civilian position where he analyzed the activities of Japanese fisheries. He returned stateside to finish a college degree that had been interrupted by internment. He went on to earn a Master’s and moved to Honolulu to work for the Fish and Wildlife Service. He worked with an influential fisheries scientist pioneering a holistic approach to fish management, blending fish biology with oceanography and meteorology. While in Honolulu he also began work on a Ph.D. The tuna research he is most well known for occurred when he was transferred to the Inter-American Tropical Tuna Commission in La Jolla, California. 
His scientific pursuits were cut short in a plane crash en route to Mexico City on a return trip from a scientific cruise to Clarion Island off the west coast of Mexico. Shimada was just 36 years old. Think of this remarkable scientist next time you open a can of tuna…

Hook, Line, and Thinker

As a part of my interdisciplinary approach to learning in the library, I often use philosophical questioning in order to inspire dialogue among my students. Something to think about…Is taking a creature’s life justified when it benefits the greater good? Many hake have given their bodies to science in order to not only benefit human activity but their own species as well.

Hmm, I made a Freudian slip just now. I originally wrote, “when it benefits the greater food.” I guess I’ve outed myself as a meat eater and a utilitarian when it comes to the sacrifice of creaturely bodies–within reason (remember the voles)–in the name of science.

During the three years I was sailing through the rough waters of the pandemic I took a hard look at the ocean-themed books in our school library collection. Library acquisition budgets are always tight, so I wrote a Donors Choose grant to purchase about 50 new titles. Since this occurred while I taught remote classes, my thank you package was also virtual. Students did a lovely job documenting their thanks using the tools they had available to them. I believe my NOAA experience will help me further promote the content of 551.46!

To conclude the discussion of the research on board the Shimada, I would like to profile the remaining scientists: the four fishermen of the night shift, and give a general report of the results of the cruise.

____________________________

Toby Auth, fisheries biologist with Pacific States Marine Fisheries Center (PSMFC), oversees most of the operations of the sorting, measuring and counting of the trawls. He works as a contractor to NOAA under the guidance of Ric Brodeur. Toby holds a BA in Fisheries and Wildlife from the University of Minnesota and he did both his MA and Ph.D. at the University of Maryland in Fisheries Management and he specialized in studying the early life of fish–egg, larval and juvenile stages, collectively called ichthyoplankton, basically anything fish-related that is small enough to sort of float along in the water.

As a researcher, he is most interested in understanding spawning success and food chain interactions of the Pacific coast species that come up in the trawls. Typically, Toby is at sea 30 – 40 days a year, but this year, due to the anomalous warm blob, he expects to be at sea about 50 – 60 days. The anomaly has implications for all fields of marine biology and oceanography.

In the far left of the image stands Dr. Paul Chittaro, of Ocean Associates in Seattle, WA. Paul is at sea on a research cruise for the first time in 10 years, and he’s very happy to be here. He was on board collecting fish in order to examine their otoliths, which are ear bones. Otoliths grow every day, laying down rings, almost like a tree. Analyzing these rings can give information about the fishes travels, diet and ocean conditions when they were alive.

The big guy in the back is Will Fennie, who will begin his Ph.D. at Oregon State University in the fall. The entire cruise he has been eagerly awaiting some juvenile rockfish to come up in the net and finally, in the last few nights, some did. Overall, we caught much less rockfish than in previous years. This could be for any number of reasons.

Personal Log

My experiences on board the Shimada have taught me a lot about myself and my abilities. I’ve done more writing, media processing and chatting with new people in the last two weeks than I have in the last two years. I have a greater understanding of how scientists work in the field and the importance of fisheries to the health of our oceans and the commercial fishing industry and I plan to apply that understanding in my classroom to increase students’ understanding of marine science and awareness of possible careers. To my students: “Get ready, dudes!”

Hopefully, you all have learned a lot about fisheries research, the process of science and the fascinating cast of characters who sailed with the NOAA Ship Bell M. Shimada. Maybe you’re even feeling a little inspired. Now, I know I’m an inland city kid, but I’ve loved the sea since I first saw Free Willy at the age of 7 and I’m not the only one who can trace their love of the sea to a starting point.

All the scientists on board have an origin story: one salient memory that they can credit with being the moment of inspiration for pursuing a life of study and research and a career in the field of science. If you’re curious about the world, you have the potential to be a great scientist. Science is for all people, no matter what age or situation, and these ones just happen to do theirs at sea. So, I want to know: Where will you do yours?

That’s all for now. Thank you for reading and listening and, maybe, sea you again soon!

Personal Log

Ahoy! Alex Miller, Teacher At Sea, here reporting to you from Newport, OR where in just under 24 hours NOAA Ship Bell M. Shimada will be underway for 15 DAS (days at sea) which will be filled with fisheries research, seabird surveys and other oceanographic endeavors that I will do my best to report faithfully and in vivid detail. For all images and video, click for a larger view.

 

Preparing for Sea

My adventure started with my arrival into PDX, the airport in Portland, OR, yesterday afternoon around 2:00PM. I was lucky enough to have the generous Amanda Gladics, a biologist from Oregon State University, pick me up and give me a place to stay before our trip down to the coast this morning. Apparently no one told either of us that we were going to have plenty of time onboard the ship to get to know each other because, after grabbing some snacks to make it through those upcoming night shifts, we sat up in her living room and talked until both of us looked around wondering why it was suddenly dark outside and we were both starving.

We set out at 0700 this morning in order to be in Newport by 1000. (NOAA and other maritime organizations use the 24-hour clock, which begins at midnight and counts up, so from here on out I will be using that format for time keeping). Amanda and I drove (well, she drove, I talked) down this morning so that she could attend a lab meeting with other scientists to prepare for her time onboard the Shimada.

A view from the front seat along Route 20.

As we drove in along Route 20 and through the Yaquina Valley, all I could see for miles were forests of Douglas Firs. Timber is a major industry in the Pacific Northwest and the timberlands out here cycle through periods of harvest, planting and new growth. Amanda remembers a section that was planted when she moved away from Newport just 6 years ago and those trees look to be almost 40 feet tall already! So for most of the 2.5 hours from Portland to Newport, our landscape was uninterrupted green, and then we came around a bend in the road and the tree line abruptly stopped, giving way to the steely gray ocean and my future home for the next two weeks.

Crossing the Yaquina Bay Bridge to reach the Hatfield Marine Science Center, I learned just how unskilled I am at taking pictures in a moving car, so after I met NOAA researcher, Ric Brodeur, Chief Scientist of our cruise, I took a hike up a nearby dune (which I later learned is affectionately called “Mount NOAA” because it is the sand that was dug out to make room for the large NOAA ships to dock without getting stuck on the bottom of the bay) to try and capture some images that actually do justice to this beautiful place. Later today Ric will take me to make sure I have all the waterproof gear I’ll need and then we’ll load up all the equipment and either have dinner onboard the ship or maybe get a chance to explore a seaside restaurant. No matter what we do for our last meal before launch, last night was my last night on land. I’ll sleep onboard the Shimada tonight to be ready for launch at 0800 tomorrow.

Once the cruise is underway, the researchers onboard have several goals they hope to accomplish during their time at sea. When NOAA ships go to sea, they have a mission statement that describes their main purpose for heading out; often however, other researchers can benefit from being at sea as well and will join the cruise but have other research goals in mind. Ric Brodeur and other researchers from Oregon State University plan to use these 15 DAS (Days at Sea) to characterize the plankton groups found just off the coast. Essentially, I’ll be helping them find and net samples to figure out what these groups are like. They’re paying special attention to young–referred to as larval or juvenile depending on age and development level–pelagic—meaning they are found near the surface of or in the first 10-30 m of ocean–rockfish and plankton. I’ll keep you informed of the goals of the other scientists I meet onboard the ship.

A Bit About Me

Back in Chicago, I am a member of the Village Leadership Academy family of schools. As the science teacher at the Upper School, I aim to bring my students relevant content that will prepare them to be informed leaders that are capable of confronting future challenges. Our school teaches a social justice focused curriculum so my goal as an educator is to instill a love of learning about the natural world, but also a sense of stewardship and responsibility to the other creatures that share our home. Social justice and environmental justice are inextricably linked and too often, the most vulnerable populations, human and animal alike, bear the brunt of the abuses of the environment.

I believe education and awareness are part of the biggest reasons ocean conservation is not a hot-topic issue for all Americans. Just look at how much of the country is inland! While my students and I may take a field trip to the wonderful Shedd Aquarium every now and then, the ocean, and the life within it, cannot help but remain an abstract concept for someone who has never seen it. I wish I could take them all on the ship, but for now, I hope that my experiences as a Teacher at Sea will help to open eyes to the reality of the oceans and shed more light on the importance of maintaining their health and creating a more environmentally-just future, not just for marine life, but for all life on this planet.

 

Signing Off

That’s all for now! Stay tuned over the next two weeks as the Shimada travels up and down the coast between Flint Rock Head, CA and Gray’s Head, OR, trawling for young rockfish and keeping its eyes peeled for seabirds and marine mammals.

Did You Know?

The NOAA Corps is one of the seven uniformed services of the United States of America. This means there is a chain of command, with the Executive Officer or XO in charge of overseeing all operations and issuing orders to maintain those operations onboard each NOAA ship. I’ll be sure to follow orders and do my part to make the cruise run smoothly!
