Science and Technology Log

Let me set the scene of an average tow for you. A conveyor belt of flopping fish (and others) moving at a rate of, what I estimate, sometimes hundreds of fish a minute. Practiced hands are moving with precision and speed to pick out dozens of fish and place them into their respective buckets. Oh–also–the ship is reorienting itself towards the next survey station so there’s a fair bit of unpredictable jostling. Gushing water sloshes around inches deep on the floor. The sensory experience is unlike any I’ve experienced before.

Most of the fish are one of two small, similar species, both silvery with yellow pectoral fins. in the foreground is a horseshoe crab; two other horseshoe crabs, lying amid the fish at odd angles, appear toward the back of the photo. — Quick–what species do you see?? I spy a couple horseshoe crabs, croaker, and some spot…

It’s overwhelming, but also such a thrill. I’d describe it as a similar experience as one of those blind boxes you can get at your local toy store. Just like the outside of the box has pictures of the types of toys you’ll get, we have a fairly good idea about what species to expect. But, there’s always the chance you might pull a never-been-seen-before fish.

For the first few days, it felt like everyone was speaking in code, especially when it came to the names of some of the animals we were catching. I’d never heard the words “Loligo” or “Illex” in my whole life. Eventually, though, I figured out that those terms translated to “squid,” and that’s as far as I’ve gotten.

five small squid laid out at random on an electronic measuring board. they are not yet arranged straight against the measurement line. the largest may be 20 centimeters. — Squid lined up on the fish measuring board.

I’ve put together this brief list of must-know species that we commonly encounter that are frequently mistaken for one another. Maybe by the end of the trip I’ll be able to tell them apart…

Squid: Illex & Loligo

There are quite a few types of squid we could come across during our survey, to include Shortfin (Illex illecebrosus) and Longfin Squid (Doryteuthis pealeii). Illex have shorter triangular fins than the rounded longer fins of a Loligo. The skin of a Loligo will slough off more easily. Coloration also varies between the two squid, with Illex more of an orange-brown and Loligo leaning purple and pink.

scientific illustration of a longfin inshore squid — Loligo are also called Longfin Inshore Squid, Winter Squid, and Boston Squid. They have had multiple scientific names, some of which include the Loligo genus (NOAA Fisheries).

Spot & Atlantic Croaker

You’d think this one would be intuitive for me, considering this Spot (Leiostomus xanthurus) and Croaker (Micropogonias undulatus) are the two of the fish we catch the most during our seining programs at the Nature Center, but unfortunately not. The most helpful tip is that a spot will have, well, a spot!

close-up photo of an Atlantic croaker against a gray background — Atlantic Croakers have much more heft to them, as well as a slight protruding point to their caudal fin, or tail (Florida Museum photo by Zachary Randall).

However, especially when dozens of them are flopping vigorously and moving on a conveyor belt, that tiny spot can be hard to find. The area on a croaker where the pectoral fin meets the body can also be dark and round (not unlike a spot’s spot…).

Four-Spot, Ocellated, Windowpane, & Summer Flounder

I’ve always been fond of flatfish. They’re such a funky shape (and typically quite delicious as well). At the Nature Center, we had an adorable Summer Flounder named June.

We’ve come across plenty of flatfish during this cruise. The main ones that I have the most trouble telling apart are the Fourspot (Hippoglossina oblonga), Ocellated (Ancylopsetta quadrocellata), Windowpane (Scophthalmus aquosus), and Summer Flounder (Paralichthys dentatus). All four of these species are left-eyed flatfish, meaning that if you placed the fish with the mouth oriented upwards below the eyes, they would be on the left side of the fish.

close-up view of a very circular, very stripey flatfish in a white bucket of water. its tail is like a small circle attached to a large one. — We caught a very distinct right-eyed flatfish, the Naked Sole (*Gymnachirus nudus*).

So, the eyed-ness (that’s not a word but you know what I mean) is not gonna help you much with differentiating this quartet of resemblant fish; you’ll have to zoom in and take a closer look at their unique features.

A Fourspot Flounder will have four very distinct eye-like dark spots, called ocelli. They are situated in pairs with one pair closer towards the tail and the other in the middle of the body. Of course, it’s not just the fourspot flounder that will have four spots.

The Ocellated Flounder will also have four large ocelli, but they will be distributed across the body differently. Three of an Ocellated Flounder’s spots will be in a triangle shape towards the right half of the body and the last spot above the pectoral fin.

Lastly, the Windowpane and Summer Flounders are going to have smaller spots scattered along their bodies. Windowpane Flounder are named for their thin, near-transparent bodies. They are more rounded than the other similar oval-shaped flounders. Windowpane Flounders have many small dark spots. In contrast, Summer Flounders typically have five larger prominent ocelli towards the tail-end of the body. Summer Flounder can reach up to forty inches, whereas windowpane tend to max out around about half that. Another helpful diagnostic feature is that the dorsal (upper) fin of a Windowpane Flounder will have fringed rays towards the front, almost like little hairs.

Aw, Shucks

I’ve been lucky to have some of the freshest seafood I’ve ever encountered over the past week. The whole mission is an indescribable undertaking, and one of the ways those onboard are rewarded is through being able to eat our catch.

It’s truly a group effort with every team having a hand in the process in some way. The deck crew is pulling up the giant hauls while coordinating with the bridge. The engineers are scurrying around fixing things before anyone even notices they need repairing.

The science team is measuring and processing. The team estimated this tow to be over 3,000 pounds, with the overwhelming majority of the haul Atlantic Sea Scallops (Placopecten magellanicus).

Throughout my time on the ship I’ve learned not only a lot of technical science, but also picked up some skills I never knew I’d learn onboard. If you need someone to shuck about a hundred scallops with minimal precision but a lot of enthusiasm, I’m your girl. I’m also not afraid to get my hands dirty (or rather, inky) and prep dozens of Loligo for some fresh calamari.

Personal Log: The Pros and Cons of Night Watch

Pro: Talk about a golden hour!! You’re rewarded halfway through your shift with a sunrise view unlike any you can see on land. The flying bridge gives breathtaking views from all directions.

Cons: My meals are all outta wack! I’m truly a creature of habit–on land I alternate pretty consistently through my go-to breakfast foods of apple cinnamon oatmeal or Lucky Charms. However, when your breakfast is at 11 p.m., what’s the move? Should I be eating the meal the Steward Department saved for me from a few hours before while I was fast asleep, or do I adhere to strict traditional breakfast foods?

Did You Know?

Did you know that some people can’t visualize anything in their mind? It’s estimated that about 1% of people experience a lack of visual imagery, also called aphantasia. Unfortunately for me and my species identification abilities, I fall into this 1%. On the other hand, many of my science team members can mentally call up an image of a fish with such precise colors and details that they basically turn into a walking field guide.

Science and Technology Log

I discovered this week that the project I am on has a much longer name than I thought. It’s been referred to as the “Bottom Trawl Survey” or “The Mission,” and if we’re feeling really fancy, the “Northeast Bottom Trawl Survey.” However, the formal name is the Northeast Fisheries Science Center’s Multispecies Bottom Trawl Survey. With a name like that, it makes sense that folks would shorten it, but there’s actually a lot to learn from the whole title.

This NOAA web page will provide you with tons of technical expertise and a great short video explaining the process. It goes into the nitty gritty of the mission, so I encourage you to check that out for a deep dive. But, if you don’t have time to fall down a research rabbit hole, here’s the basics:

The overarching goal of the Northeast Fisheries Science Center’s Multispecies Bottom Trawl Survey (NEFSC BTS) is to gather fisheries data. There’s a lot of information jammed into that one sentence, but it makes much more sense when it’s broken down.

The Northeast Fisheries Science Center (NEFSC) is part of NOAA’s broader North Atlantic Region, whose range spans from New England to the Mid-Atlantic. Over 70 million people live in the region, many of whom live in coastal or near-coastal zones.

The states and territories making up a region are all the same color. — Map of NOAA’s regions, with the North Atlantic region highlighted in purple (Map from NOAA).

Northeast Fisheries Science Center’s mission is “to provide the scientific information and tools necessary for productive, sustainable, and healthy marine ecosystems and coastal communities in our region.” There are multiple research facilities scattered along the coast, as well as the country’s oldest public aquarium, Woods Hole Science Aquarium! (Please note that the aquarium is closed through early 2027 for major renovations, but will certainly boast some awesome new exhibits!).

An inset text box reads: "We cover over 160,000 square miles of ocean from North Carolina to Maine." — Functions of the NEFSC are carried out at research facilities in Connecticut, Maine, Massachusetts, New Jersey, and Rhode Island (Map from NOAA).

The NEFSC’s work doesn’t stop on land, of course. Some specimens have to be collected from their natural habitats, sometimes hundreds of meters beneath the sea surface, and brought back to study. Skipping ahead in our project title, that’s where projects like the Bottom Trawl Survey come in.

A trawl is a type of net used to catch fish and other fun sea creatures. There are different types of trawl nets, all with different goals for catching certain types of animals or adaptations to the physical conditions. For example, the net on NOAA Ship Henry B. Bigelow has a rockhopper sweep for rocky bottoms.

hands from three different crewmembers reach out to repair a teal fishing net crumpled up on deck — Science and deck crews working to repair the net.

A bottom trawl targets species in, you guessed it, the bottom of the ocean! The net used in the BTS is standardized down to the model of metal connectors and number of knots in the mesh.

When we say that the project is multispecies, the simple definition of “multiple species” almost doesn’t do it justice. There are obviously plenty of fish to be studied, but also shellfish like scallops and crabs. Much of the data collected is used to perform regional stock assessments, or population measurements, of more than 40 species. All finfish and some invertebrates are all weighed and measured. That doesn’t even include all the invertebrates or plants that we don’t catalog further!

close-up view of two spider crabs placed next to one another (but facing opposite directions) on a measuring board — Spider Crabs lined up on the measuring board.

Lastly, a survey in this case refers to the methodical collection of scientific information. There are standardized protocols to ensure that the year to year data can be used by researchers. Not all species are processed the same. Some are preserved whole in formalin or freezers, others are simply measured. The procedure really depends on the needs of the researcher. Researchers interested in requesting samples can submit online forms that are reviewed and potentially included as collection points in surveys.

Would you believe me if I told you that the fish collection doesn’t even scratch the surface of the projects onboard? There’s environmental, acoustic, biological, and oceanographic data collected throughout the cruise as well. The Deck and Survey Technician teams play a large role in the execution of those projects, so I’ve witnessed fewer of those operations. I’m excited to connect with them and chat about their roles on the ship.

Personal Log: First Watch

The first couple days on the ship have a “summer camp” feel to them. People that see each other only a few times a year but spend almost every single hour together form a unique bond. Every single meal is together, you’re all working towards a specific set of goals. There’s so much shared history. People are bouncing stories back and forth while I quietly observe from the fringes.

Everyone has been extremely welcoming and helpful, which is a big relief. Still, though, there’s always that sort of (excuse the bad joke) “fish out of water” feeling of entering an entirely new situation. Trying to remember everyone’s names, faces, job titles, organization affiliations–all of it is swarming around in my brain trying to take hold.

Waking up at 11:00pm and starting a twelve-hour shift is not something I’m accustomed to. Luckily, today was a relatively well-paced day with our work spread out with breaks in between to rest and mentally process the massive influx of information I’ve received. The main thing I did today was orient myself with the workflow of the lab spaces.

There’s a Wet Lab, Dry Lab, Acoustics Lab, Chem Lab, Hydro Lab, and maybe even some other secret labs I’ve yet to discover.

a computer tower and array of 10 monitors at a computer desk — The Acoustics Lab has lots of fancy computers that track important things. Being in here gives me a great view of the cameras of the deck operations so I know what stage of the tow we’re in.

All the online research in the world won’t compare to actually seeing the operation in action. My job was to help sort the fish as it comes down the belt. They get sorted by species, and then sometimes even further divided by size and/or sex. After sorting, they get examined and data is collected. My role was to be a Recorder, meaning I assist with organization of the fish prior to measurement, entering data into the computer system, and labeling samples. It’s extremely overwhelming, like trying to quickly learn a new language, but even after one shift I’ve already got a better handle on it.

NOAA was officially established in 1970 to combine the country’s first agencies for physical science (U.S. Coast and Geodetic Survey), atmospheric sciences (Weather Bureau), and conservation (U.S. Commission of Fish and Fisheries). The original emblem design lives on to this day, meant to represent the connection between the Earth, ocean, atmosphere, and ecosystems. Learn even more about NOAA’s history here!

In many ways, ships are like their own living organisms. From pontoons to sailboats, rowboats to mega-yachts, ships come in varieties just like plants and animals.

Preparing for the trip, I tried to approach learning about NOAA Ship Henry B. Bigelow as a species to study just like any other fish or bird species. I find research very comforting, so I tried my best to learn about ships in general, and the features of Henry B. Bigelow. NOAA has some excellent resources that cover the history, construction, and scientific specifications of the vessel. The end of this blog post contains links so you can dive even deeper, but here are some of the highlights (including some of my observations from onboard).

Basic Anatomy: Important Parts of a Ship to Know

Also called a command deck, wheelhouse, or pilothouse, the bridge is like the brain of the ship. This is where much of the navigation and mission logistics happen. Those working on the bridge also must maintain constant communication with other teams aboard, such as the engineers, scientists, and other crew.

On Henry B. Bigelow the bridge is very spacious and well-equipped with technology used to ensure that factors like the direction and speed are maintained as the scientific operations are performed. The bridge is commanded by a team of officers from the NOAA Commissioned Officer Corps.

The engine room is the heart and lungs of the operation. Without the engine machinery to propel the ship, you’re not getting very far. I have yet to see Henry B. Bigelow‘s engine room; that is a sensitive area. I’m a little nervous to inquire further because I know one thing for sure: engine rooms are LOUD.

What else could the mess and galley be other than the digestive system of a ship, of course? Food is stored and prepared in the galley and the crew aboard the vessel have their meals in the mess hall.

Also sometimes called cabins or berthings, staterooms for sleeping accommodations allow the hardworking crew aboard the ship to get some much-needed rest between watches. My room is a four-person room with two sets of bunk beds with a bathroom attached. There are also some rooms that are singles or doubles depending on the staffing needs of those onboard.

Life History

NOAA Ship Henry B. Bigelow is one of many within NOAA’s fleet of state-of-the-art research vessels. The construction of Henry B. Bigelow and other ships of the fleet were built with the intention of providing optimal facilities for NOAA’s scientists.

It was built in 2007 by VT Halter Marine Inc., in Moss Point, Mississippi. Because it was built for the purpose of being a fisheries survey ship, it has lots of unique characteristics not found in other vessels.

It has instruments used for recording crucial data for NOAA’s various projects. The ship is home ported in Newport, Rhode Island and its primary purpose is to perform fisheries stock research along the U.S. East Coast, including the Fall Bottom Trawl Survey that I am part of this year. Read even more about the other types of capabilities of Henry B. Bigelow here.

Personal Log

All aboard! We’ve arrived, folks. I landed in Rhode Island and was able to explore Newport. Okay, okay, perhaps I overpacked, but listen – my father, a retired U.S. Coast Guard Captain, instilled the official “Semper paratus” motto meaning “always ready” deep within me. Who knows what I might need?? Trekking about 100 lbs of luggage through the airport was quite the journey. I chose to count that walk to my rental car as my workout for the day.

After a lovely stay in Newport, I met up with the science team members that were also boarding the ship for the first leg of the bottom trawl survey. The large van transported us to the Navy pier where we then boarded a small boat to be transferred onto Henry B. Bigelow. Because we had about a dozen scientists with all their gear, we took multiple trips. I was on the last batch of folks transferred over so I boarded in the late afternoon. The evening included a whirlwind of orientation of the ship, safety trainings, and sneaking in a quick meal.

Personal Log

It’s wild to think that this opportunity could have drifted past me if I hadn’t opened a random email from one of the many environmental newsletters I’m subscribed to. In some ways, though, it was something that I manifested back in elementary school. My name is Melina Vella and I am thrilled to be writing my first blog post as a NOAA Teacher at Sea. Currently, I work for the Delaware Division of Fish and Wildlife as an environmental educator at the DuPont Nature Center.

By almost all accounts, my dream career growing up was to be a scientist. I recently sifted through bins of keepsakes spanning my years of schooling, and every “get to know me” assignment documents a clear plan. Aside from one deviating record that listed my aspiration to be a dentist (perhaps around the time my brother was getting his braces put on), science was always my end goal.

(2) A worksheet titled "Who Am I?" that ends in the prompt: "When I Grow Up I Would like to be" and Melina's answer: "scientist." (3) a photo of a collage with cut-out printed statements (the top reads: "I want to be a type of scientist when I grow up. Most likely a paleontologist or a chemist." and a photo of a young Melina. — Assignments from elementary school demonstrating my aspirations of being a scientist.

I wonder if past me would consider my present-day self a scientist. My undergraduate degree is technically a science degree, but in practice I’m not a scientist. So, in some ways, this expedition is fulfilling a childhood dream that no one will be able to argue: I’ll be a scientist.

Why the trip down memory lane? Well, I bring up these artifacts from many moons ago to illustrate that my interest in science started when I was only five years old. My passion was enhanced by field trips to the aquarium and my very first lab dissection of a flower in fifth grade. I was encouraged by my teachers to compete in the science fair each year. Through my position as a naturalist at the DuPont Nature Center, I have the chance to make that core memory for hundreds of kids visiting on field trips. Every single week for months I lead programming for students from dozens of local homeschool groups, public schools, daycares, and more. The overarching goal of these field trips while the kids visit is to connect them to the Delaware Bay, one of the state’s most important natural resources.

We all have some sort of relationship with the Earth, whether we want to or not. For some, the love they have for the planet is what drives them day in and day out. For others, they might not give a second thought to the impact their decisions have on the land, sea, or atmosphere. However, sometimes all it takes is finding a beautiful bivalve shell on the beach or petting a horseshoe crab for the first time to instill that desire to keep exploring.

That brings me to how I ended up here, as part of this program. The foundation of my education is environmental science, with an intense focus on ecology in marine environments. Unfortunately, one of the results of the COVID-19 pandemic spanning my junior and senior years of college was that the classes that typically offer field and lab opportunities were instead virtual. Alas, I never dissected a shark in my elasmobranch class. So, when the chance to actually go on a research cruise with NOAA came across my screen, applying was inevitable.

I’ve been lucky enough to have some very unique work “offices,” including on Nantucket Island as a summer camp environmental educator for a non-profit and the woods of upstate New York with the Cornell Lab of Ornithology on a field research project. Another unique one was a small fishing boat, also operating as a summer camp, but specifically for young anglers.

This upcoming trip will be the longest I’ve ever been on a boat at once! I hope to absorb as much as I can through this experience and take it with me for the rest of my life. This opportunity will give me an entirely unique experience that very few people get to have each year. I’m excited to meet new people and learn more about what it actually takes for a research project to be successful day-to-day. We’ll all have our roles, and I hope to add value to the team while I’m there by bringing my natural strengths and past experiences along with a passion for pushing myself to always try new things.

Science and Technology

Why survey scallops? The fishery stock assessments study the size and age composition of approximately 40 fish and invertebrate species in the New England/Mid-Atlantic area. This data informs stakeholders and policymakers of the abundance of each species, the impact of the fishing industry, and evaluates biological aspects of the ecosystem. (Fishery Stock Assessments in New England and the Mid-Atlantic) The data collected by NOAA and other sources (including commercial and recreational fishermen) is then used to determine sustainable harvest levels for each species (See graphic below). Find more information HERE.

This image has four sections with arrows to show the progression from data analysis to stock assessments to management advice to healthy fish stocks. Commercial data, recreational data, and scientific data inform stock assessments and are represented by outlines of the three different types of vessels. Stock assessments answer questions including, “How are the stocks doing now?” and “What are the future projections?” and this section has outlines of fish and a fishing net. Stock assessments inform management advice, the next section, with icons for licenses/permits, fishing seasons, gear, quotas, and size limits. The final section and overall goal is “healthy fish stocks” with line drawings of fish on a plate for sustainable seafood, fish below a fishing vessel to represent future jobs, and a squid, lobster, and urchins to represent healthy oceans and marine life. — An infographic shows the progression from data analysis to stock assessments to management advice to healthy fish stocks.

How is this survey conducted? The Atlantic Sea Scallop survey has four main components: dredge, trawl, a long-range autonomous underwater vehicle (AUV), and Habitat Mapping Camera (HabCam).
– A dredge has a metal frame with a chain-mesh bag that collect scallops off the sea floor, like raking leaves in your yard.
– The trawl uses a net to scoop up swimming scallops without digging into the sediment.
– The HabCam, what I worked with on this survey, is a boat-towed camera system that takes continuous paired photos, 5-6 pairs per second, as it moves through the water (NOAA survey preparation materials).
– The Autonomous Underwater Vehicle (AUV), “Stella,” has the same camera system as the HabCam, but can be programmed to operate without a human pilot.

“Approximately 4 million images of the ocean bottom are collected during an annual survey. Humans are annotating about 1 in 50 of the images.” (NOAA Fisheries)

What is a HabCam? Watch THIS VIDEO!

What do the HabCam images LOOK like? The HabCam system captures high-resolution images and transmits them to a computer for processing and annotating. This is what that looks like from the pilot station:

The Atlantic Sea Scallop Management Program is broad and complex, involving many different aspects of research, management, and monitoring. You can read more about it at the NOAA Sea Scallop Management page.

Personal Log

On NOAA Ship Henry B. Bigelow, there are both two- and four-person staterooms. Megan and Kristen are on day shift, so I usually only see them during watch changes. Sandy, however, is on night shift with me.

Sandy Sutherland is a research fishery biologist at the Northeast Fisheries Science Center. She earned a bachelor’s degree from Eckerd College and a master’s degree from University of Rhode Island Graduate School of Oceanography. She started her career as an outdoor educator with Nature’s Classroom.

At the Northeast Fisheries Science Center Woods Hole lab, Sandy conducts age determinations for haddock and Atlantic mackerel and measures growth rings for sea scallops. Using a dissecting microscope, she determines the age of fish earbones (otoliths) — a process she says feels a bit like playing a video game. She also conducts research related to age determinations and created Excel templates used to calculate measures of age precision.

She says important skills for this type of work include paying close attention to detail, writing legibly, and being able to see how all the pieces fit together to understand the “big picture.”

When she’s not working, Sandy enjoys birding, reading, and volunteering at science fiction conventions such as Readercon. Although she can’t choose a favorite bird, she says she would be especially excited to spot any species of albatross.

Did you know sea scallops can swim?

They rapidly clap their shells together to move away from predators, like sea stars. And we can actually “see” this from the HabCam images! In the image below, the sea scallop appears to be swimming away from a predator. A swimming scallop can be identified by the two dark “shadows” visible on either side of it. Can you see the predator???!

Careers at Sea

Meet Jonathan Duquette, a Biological Science Technician with the Ecosystems Surveys Branch at the NOAA Northeast Fisheries Science Center. He specializes in shellfish surveys involving Atlantic sea scallops, Atlantic Northern Shrimp, Ocean Quahogs, and Atlantic Surfclams. Jonathan plays an integral role in critical research initiatives, including the high-resolution HabCam (Habitat Camera Array) and sea scallop dredge surveys. His work at sea and ashore supports the rigorous monitoring, data analysis, and ecological assessments essential for sustainable fisheries management and marine ecosystem conservation in the Northeast.

Jonathan has had a lifelong obsession with the sea, sharks, and fishing since an early age. After graduating with a BS in Marine Biology from the University of New England, Jonathan became a fisheries observer collecting data for the federal government on vessels in Alaska. After working as an observer on King Crab fishing vessels (think TV’s “Deadliest Catch”), longline vessels, and Scallop fishing vessels, he returned to the East Coast where he worked as a sternman on lobster fishing vessels in Boothbay Harbor Maine. In 2003, Jonathan joined the Ecosystems Surveys Branch at NOAA’s Northeast Fisheries Science Center, a role that continues today.

I asked him if he had any advice for “his younger self.” He said, “I’d tell myself that persistence pays off, and that you’re really never gonna be done learning, it’s a lifelong pursuit. Don’t be afraid of making mistakes, that’s part of the journey.”

Fun fact: While on a research cruise in 2024, Jonathan and other scientists discovered an ice-age jawbone from a Walrus, off the coast of Virginia! Read about his exciting discovery HERE!

Meet Zach Fyke, he is a Biological Science Technician with the Northeast Fisheries Science Center Ecosystems Survey Branch. He graduated from Michigan State University in 2017 with a degree in Fisheries and Wildlife. After college, he began his marine science career as a fisheries observer based out of Point Judith, Rhode Island, before taking on several positions within NOAA Fisheries. Today, he primarily works on shellfish surveys involving Atlantic sea scallops, Atlantic Northern Shrimp, Ocean Quahogs, and Atlantic Surfclams.

Interestingly, Zach originally planned to be an educator, but after an elective Intro-Biology course, he found himself declaring into the major of Fisheries and Wildlife. Near the time Zach was graduating with a degree in Fisheries, a college professor at Michigan State University, who had worked at the Woods Hole lab in the 90’s, encouraged him to “try somewhere new for a few years.” This was a driving factor on why Zach moved to the East coast to begin a career in Marine Fisheries. Zach describes himself as an “average student,” but says he always enjoyed hands-on activities and learning by doing. That passion for fieldwork and adventure eventually led him to a career at sea.

His advice to students interested in science careers is simple: don’t be afraid to move away and try something new. Some of the best opportunities are found outside of your comfort zone.

When he’s not working, Zach enjoys photography and has recently started photographing birds. He jokes that birding is a lot like “real-life Pokémon.” His favorite bird is the Belted Kingfisher.

Personal Reflection

Scallops may blend into the seafloor until they suddenly swim off in a burst of movement — a fitting reminder that sometimes growth happens when we are willing to move beyond what feels comfortable. Whether it’s learning to annotate images, transitioning to night shift, or piloting the HabCam, this journey has been a reminder to BE the Scallop in a sea of sand dollars.
