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.

(Read this for more details: Long-Running Sea Scallop Survey Diversifies for the Future)

“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???!

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.

Air Temperature: 10.5 °C (50.9°F)

Science and Technology Log

The Habitat Mapping Camera System (HabCam) has been taking LOTS of pictures of the life near the sea floor. As part of the nightshift, my duties include annotating the HabCam images, driving the HabCam vehicle as Pilot, and serving as Co-Pilot.

Annotating images involves identifying and measuring scallops, as well as identifying other animals like round fish, flat fish, skates, crabs and whelks.

As Co-Pilot, there are several monitors with varying data from both the ship and the HabCam that must be watched in order to see obstacles on the path to avoid a collision. The depth of the HabCam is controlled by a “joy stick” that deploys and retracts the cable attached to the frame surrounding the HabCam. Ideally the camera should be kept within 2 meters from the ocean bottom.

As the Pilot, I must constantly monitor and adjust for the ever-changing distance from the seafloor to keep the HabCam from touching bottom. Some areas are easy to navigate, while others are rocky with “surprise” boulders.

BEFORE Annotations

National Oceanic and Atmospheric Administration (NOAA) places a strong emphasis on producing reliable, standardized research data, so I was required to watch a training video, pass a verbal quiz, and then take a 200 image test to ensure my annotations met those standards.

Drifter Buoys

Through NOAA’s Adopt a Drifter Program, I also had the opportunity to deploy two drifter buoys while aboard the NOAA Ship Henry B. Bigelow. The mission of this program is “to connect classrooms around the world with NOAA data, and provide a real-life, interactive classroom experience to teach students about ocean science” (Adopt a Drifter Program). After decorating the buoys, we deployed both buoys from the starboard side of the ship at 5:21 AM and 5:22AM on Friday, May 22, 2026. As soon as I have a link to track them, I will post here!

If you or your school would like to adopt a drifter buoy, you can find out more information HERE.

Personal Log

Ship living isn’t all that bad, but night shift has been an adjustment! I am in a stateroom with three other ladies; two of us are on night shift (11:30 PM – 11:30 AM) and two are on day shift (11:30 AM-11:30 PM). When you leave for watch, it is common courtesy to NOT return to the stateroom when your bunkmates are sleeping. *It’s a good idea to set your things out before going to bed so your essentials aren’t left behind!*

What day is it? Not really sure…But I have thoroughly enjoyed getting to know the crew and learning how the HabCam collects images of sea life and how NOAA uses this data to inform the local fisheries. More about the crew later!

I’ve had the opportunity to see some amazing sunrises…

And today, we had the honor of watching humpback whales while SNOW fell!

Did You Know?

The Humpback whale can weigh up to about 40 tons, grow to around 60 feet (18 meters) long, and live roughly 80–90 years. They are known for their long migrations, complex songs, and acrobatic behaviors such as breaching and tail slapping. Humpback whales are found in oceans worldwide and feed mainly on small fish and krill (Humpback Whales – NOAA). They are also called the “singing whale,” because the male mating song can change from year to year and can last as long 30 minutes (Fun Facts About Wonderful Whales).

Although humpback whale populations are increasing, they remain on the endangered species list. Their greatest threats include entanglement in fishing gear and marine debris, vessel strikes, harassment from boats, ocean noise, and changing climate conditions (Humpback Overview – NOAA).

Did you know different animals (and fish) make specific sounds? Watch the following video to learn more about how NOAA Fisheries uses Passive Acoustic Monitoring to study not only the humpback whale, but many different types of sea life! Listening for Whales. Visit the NOAA Mammals: Sounds in the Ocean site to hear the differences between 32 mammals including the humpback whale and the minke whale!

Careers at Sea

(Credit Rhett Finley)

Meet Rhett Finley, a fieldwork team lead from the NOAA Passive Acoustics Branch in the Northeast. Rhett grew up in Tulsa, OK and developed a passion for science at just 6 or 7 years old. By the age of ten, he already knew he wanted to become a marine biologist, inspired by the nature documentaries he watched growing up. He later attended Texas A&M University at Galveston, where he earned a Bachelor of Science degree in Marine Biology.

When I asked Rhett how he became drawn to the field of bioacoustics, he said “it was because of its versatility and noninvasive nature and the ability to integrate it with other scientific disciplines, like genetics. This approach is an effective means of collecting detailed data on threatened species especially in remote or difficult to access areas and therefore can contribute to well-informed conservation management efforts for those species and their respective habitats.”

His job with the NOAA Fisheries Passive Acoustics Branch involves:
– placing underwater microphones (hydrophones) in designated areas, such as wind farm areas and marine sanctuaries
– assists with analyzing and interpreting acoustic data, which is visualized in the form of spectrograms (picture below).

His current focus is on the minke whale (Balaenoptera acutorostrata). More information on this whale found here. The goal of this NOAA division is to “use passive acoustic technologies to study the behavior and movements of marine animals, their contribution to the ocean soundscape, and how they are affected by human-made sounds” (Passive Acoustic Research in the Northeast)

Introduction
Hello! My name is Amanda (Mandy) Freeman from Richburg, South Carolina and I am BEYOND ecstatic to begin my adventure aboard NOAA Ship Henry B. Bigelow for the NOAA Teacher at Sea 2026! This is my 28th year of teaching high school science and my 19th year at Lewisville High School in Richburg, South Carolina.

Lewisville Lions

In my classroom, I work to bridge science concepts with real environmental challenges so students recognize their impact on the world and understand how biology applies to their daily lives. As a high school science teacher, I often talk about ecosystems, human impact, and sustainability, but this experience will allow me to move beyond talking about it and actually do it! The NOAA Teacher at Sea Program will allow me to bring authentic scientific research into my classroom while exposing students to a variety of potential career paths.

Packing
OH MY…What do you even pack for life at sea?! What shouldn’t I pack?!

In South Carolina, May usually means temperatures somewhere between 26°C to 13°C (80°F – 56°F), so trying to prepare for the much chillier weather in Rhode Island has definitely been a challenge. My suitcase currently contains everything from t-shirts to sweatshirts to rain gear… and I’m still convinced I’m forgetting something important.

Hopefully, I’m just overthinking it – although there’s a very real possibility I’ll either freeze, overpack or both!

Excitement
Excited doesn’t even begin to describe how I feel about this opportunity. In just a few days, I will go from teaching biology in a classroom to living and working aboard the NOAA Ship Henry B. Bigelow alongside real scientists conducting fisheries research.

I’m excited to experience what life is really like on a research vessel, learn how scientists collect and analyze data at sea, and see technology in action through the HabCam survey. Most of all, I’m excited to bring these experiences back to my students. OH – and did I mention I’ll have the opportunity to deploy TWO drifter buoys?! How amazing is that???!!

For many of my students, careers in marine science or ocean research may seem far away from our everyday lives in South Carolina. I hope this journey helps them see that science is more than a textbook or lab activity — it’s exploration, discovery, teamwork, and problem-solving in the real world.

I can’t wait to share photos, stories, challenges, and discoveries from this adventure. Hopefully my students will learn right alongside me as we trade our normal classroom walls for the open ocean!

Stay Tuned!

Science and Technology Log

Next Tuesday, I will board NOAA Ship Henry B. Bigelow from Woods Hole, Massachusetts via a small boat transfer. The ship is a “state-of-the-art fisheries survey ship that studies a wide range of marine life and ocean conditions” ( NOAA Ship Henry B. Bigelow).

The annual Northeast Fisheries Science Center scallop survey will use the Habitat Mapping Camera System (HabCam) to determine the distribution and relative abundance of Atlantic sea scallops (Placopecten magellanicus). According to preparatory materials from the science team, the HabCam V4 is an underwater “boat towed camera system that takes continuous paired photos (typically 6 pairs per second) at approximately 2 meters above the sea floor.”
