Science and Technology Log

Yesterday we reached our northernmost station, off the coast of Cape Hatteras. These shark lovers were hoping to catch a great white there, and we had two lines that were bitten through, so there may have been one that escaped (his name was Winston, in case you were wondering).

During that station we caught two Atlantic sharpnose sharks, a large tiger shark (estimated to by 2.25 meters, or more than 7 feet long), a baby tiger shark (0.87 meters, or a little less than 3 feet), and a male great hammerhead shark that was 2.71 meters (almost 9 feet!) long.

I was so excited that I was able to tag and fin-clip the great hammerhead! From not really having much background experience with or knowledge of sharks beyond dogfish, I have had a tremendous exposure to these apex predators!

Near the next station, we were able to launch the third drifter close to the Gulf Stream. I can’t wait to share the information about these drifters with my students! The Adopt a Drifter program has lesson plans that you can check out here: Adopt a Drifter Teacher Resources.

Here are links to see where our drifters are:

Our goal in launching these drifters was to put them into the Gulf Stream to see how they behave. Perhaps they will all stay in the Gulf Stream, or perhaps they will veer out because of eddies. We shall see!

Interview with Gretchen Kruizenga

Gretchen stands next to the CTD rosette on the deck of NOAA Ship Oregon II. the sky is blue with puffy white clouds, and the ocean is a very vivid blue.
Gretchen Kruizenga, senior survey technician on NOAA Ship Oregon II, explaining to new staff the purpose and procedure for launching the CTD (Conductivity, Temperature, and Density) apparatus.

Gretchen, the ship’s senior survey technician, always has a smile on her face. She has been so helpful and supportive to me as a newbie on this project, and I appreciate her level-headed guidance and patient encouragement as I learn all the new things. Gretchen’s high energy level and enthusiasm is appreciated. She works with the science crew to bait hooks, then she hustles to collect water quality data from the CTD (short for conductivity, temperature, and depth). Gretchen grew up in Walworth, WI (graduating from Big Foot High School!), then earned a degree in Biological Sciences (minoring in Environmental Science) from Florida Atlantic University (FAU). Her avid affection for sharks is contagious. She has had an amazing breadth of experiences so far, which led her to this job in January 2023. 

Why is your work important?

“My job is vital for keeping the scientific operations running. For example, when a sensor breaks, I can replace it to keep them collecting water quality information for the survey.”

What are your responsibilities? This position is new to me.

“I am in charge of maintaining and operating scientific sensors and oceanographic sampling equipment. My job on this vessel is different than on other NOAA vessels because since this ship is small, I also stand a science watch.”

What do you enjoy most about your work?

“I love being able to work on my two biggest career passions: water quality data collection and scientific data collection. I consider myself to be the luckiest person on the ship.”

What tool do you use in your work that you could not live without?

“I’d have to say multimeter. It allows me to figure out if cables are broken or if sensors are getting enough power without having to bring the whole apparatus into the lab.”

When did you know you wanted to pursue a career in science or an ocean career?

“My dad took me to see the ocean for the first time at South Padre Island, TX, when I was 9 years old. I knew then that I wanted the ocean in my life in any capacity it could be. I originally wanted to work for National Geographic to write blogs about places around the world. I got an internship in South Africa with Oceans Research, where I fell in love with sharks. When I’m not on Oregon II, I work with American Shark Conservancy out of Jupiter, FL, to collect water quality data and shark information on recreational shark ecotourism diving boats. I gave a presentation at the American Elasmobranch Society in 2023 about that citizen science work. We collect data that would otherwise be missed.

“I found this job when I googled “NOAA shark research” and found out about this [bottom longline] survey. I’ve always wanted to work with Trey [Driggers] on this shark survey. Being able to contribute to the stock assessment data that I’ve been looking at for years is crazy.”

What is the toughest part of your job?

“The toughest part of my job is keeping a healthy work-life balance. The needs of the ship means being away a lot, which impacts maintaining social relationships.”

What part of your job with NOAA did you least expect to be doing?

“I do more electrical work than expected. I have to read a lot of manuals because there aren’t a lot of people who can answer those questions for me.”

How do you help wider audiences to understand and appreciate NOAA science?

“Coming from an outreach background, I love to share everything I learn with others. I share links and stories on Instagram to get the message out there to anyone who will listen. I do wish we had more outreach opportunities.”

Do you have any outside hobbies?

“I like to make epoxy waves (www.etsy.com/shop/GretchenEpoxSeas), kickbox, and scuba. I like to see my friends. I like to push myself out of my comfort zone. I love to travel (favorite place is Iceland).”

What do you think you would be doing if you were not working for NOAA?

“This is my dream job, but if I can’t work here anymore, I would try to do anything that combines my technical expertise with sharks.“

Personal Log

This time is flying by, and yet every day seems to blend into the next. We have a television on in the science lab while we are moving between stations, and yesterday a Meg (Megalodon) marathon was on… I I loved the quote from the movie, but the portrayal of a long-thought-extinct shark coming back to kill all the people was a little more than I wanted to think about (spoiler alert: especially when one megalodon launched itself out of the water and onto the research vessel in the movie…)

Although I am not going to officially interview her, I want to give a shoutout to Tera Winters, the other watch member who is affiliated with the University of Miami’s Cooperative Institute for Marine And Atmospheric Studies. Tera has been a veterinarian in Tallahassee and Panama City, FL, but has added marine science to her skill set. Tera takes pride in working efficiently, particularly when she is back in the lab processing otoliths (ear stones) from bony fishes to estimate growth rates and ages of individual fish. This information is a critical part of the stock assessment information, because managers need to know how long it takes (in addition to size) for fish of a certain species to reach sexual maturity. Tera has been responsible for FT-NIRS scanning, imaging, weighing, and ageing thousands of otoliths from red snapper. Without this information, the catch limits of red snapper may be miscalculated. I have been privileged to work with such amazing professionals.

Did You Know?

Sharks were around 200 million years before the dinosaurs, and they have persisted for 450 million years. Don’t you think it would be a tragic event if humans caused the extinction of any of the over 500 species of sharks that have been identified?

Personal Introduction

Hello from Brooklyn! Don’t get too excited—I’m originally from Long Island, just about 60 miles from where I now live with my partner, Clara, and our cat, Samson. I enjoy live music, building composting systems, reducing waste through organic collection, gardening, and bicycling around the city. I turn 41 on August 13—the same day we set sail on the Oregon II. This journey marks another step in my personal life and in my unexpected path as an environmental educator.

Grandfather at a house we built on the coast of Long Island.

As a kid, my grandfather used to take me to the beach on his only day off from framing houses—Sunday. I would splash in the Atlantic Ocean while he lounged under an umbrella with his aviator sunglasses on—pretty sure he was sleeping under those shades. Throughout my childhood, I subconsciously absorbed the interconnectedness between our vast ocean and our lives. Just took some adulting to figure it out. Life experiences have shown me that coastal environments offer a range of benefits, including work, play, food, culture, love, and spiritual enrichment. From my attempt at surfing in high school, being rescued by lifeguards, attending high school beach parties, and spending time at sea fishing with my commercial fisherman friend, to framing houses with my grandfather on the beaches of Long Island, I was absorbing that people use our coasts for many things. As a kid, I underestimated its importance, size, and power. It wasn’t until I moved to NYC in 2002 that I began to learn from others and observe what I had been surrounded by all my life.

Aspiring Lawyer. 🙂

I often share my high school yearbook quote with my students. It said, “I want to be a lawyer and live in a penthouse in NYC.” After graduating from high school, I set out on that path and was determined to make it happen. After island-hopping at various academic institutions in the metro area, I graduated from Stony Brook University with that degree in 2009. I continued pursuing these goals and enrolled in a master’s program in Political Science at Brooklyn College. I’m not sure what happened, but I changed course and pursued a master’s degree in Adolescent Education with a focus on Social Studies.

During my final year of the master’s program, I became involved in writing a curriculum for my final project, which focused on place-based learning and utilized the National Park Service. This would inspire me and encourage me to seek a position with the National Park Service. Over two years, I had the privilege of working at three parks: Gateway National Recreation Area, Governors Island National Monument, and Sequoia and Kings Canyon National Parks. All of these locations sparked my passion for working with youth and engaging with our communities as a classroom. The traditional classroom seemed a distant place.

Rangering at Sequoia Kings Canyon National Park

While working on Governors Island National Monument, I collaborated closely with the New York Harbor School on the island to encourage their students to use the park as a classroom. Additionally, I participated in field experiences with their students as a ranger at the school. This led me to Sequoia and Kings Canyon National Parks. I didn’t want to be a lawyer. I didn’t want to be a classroom teacher. I wanted to be an environmental educator with the National Park Service. But the dream was beyond reach and so competitive. To be honest, I also didn’t have the science chops at that point in my life.

Room 207, NYHS Global History, my first year of teaching

While at Sequoia, I got an email to come in for an interview at the New York Harbor School. I came, interviewed, and was offered the job. I began my teaching career in 2012, specializing in social studies. After spending two years at Harbor School, I relocated to New Orleans to pursue my career in education, teaching U.S. history. Eventually, I returned to Harbor School, where I was tasked with developing a policy and advocacy course as part of their offerings. With support from academic institutions and industry partners, I created a hands-on curriculum for a cross-disciplinary program called Marine Affairs, focusing on environmental science and sustainability. In this program, students explore emerging issues related to natural resources and work on solutions through advocacy. I took the leap, and I didn’t know that one day I would use all the skills from my youth, my 20s, and 30s to be doing all the professional goals I aspired to do—engaging students in environmental place-based learning that considers all the facets of the economy, environment, and culture, with the end result advocating for positive change.

Seaweed students and I help grow through volunteering with Seaweed City.

What I teach now wasn’t where I started. However, time and again, experiences I pursued led me to this path. All that I teach today, I’ve learned by doing and from those in the field. Much of what I teach has evolved from its inception—primarily because the community’s needs have evolved. Projects like seaweed farming and composting have opened my eyes—and those of my students—to the impact of local actions on global systems. I’ve become a student alongside them. My goal is always to make learning relevant, hands-on, and rooted in advocacy. I had no idea I would be teaching students about urban agriculture, stormwater management, and estuary health through greening, resilience, waterfront design, and beekeeping, with the list growing longer. I initially aspired to be a lawyer to effect change. Now, on any given day, I work with youth to create change through hands-on solutions in science and advocacy. If it weren’t for partners such as Earth Matter, Waterfront Alliance, Newtown Creek Alliance, Billion Oyster Project, FFA, Bee University, and Seaweed City, among others, I wouldn’t have gained the knowledge to have such an enriching career in environmental education. I’ve learned from my community and what the community needs. By expanding my network, my students’ networks also grow.

The collage below is now my classroom. I’ve learned to make the physical and cultural aspects of my community my classroom, adopting this approach from my surroundings and all that they have to offer—including mentors, nonprofits, city officials, and experiential learning. The Teacher at Sea mission is the icing on the cake, expanding my network and providing an opportunity to learn and acquire additional skills that I can then apply to my students. Fill in some gaps in my knowledge that I might have. As I stated, this isn’t what I intended, but I am all in now. Part of what I love, which is both a blessing and a curse, is that the course I teach depends on evolving and being spontaneous. I enjoy learning alongside my students. I am excited to bring back some fresh ideas for them to experiment with after my time at sea.

Last summer, I spent a week learning about the USDA’s diverse work around our economy, environment, and food systems from dedicated USDA employees.

This summer, I am heading to the open water to engage with NOAA on the Oregon II, which promises to be an entirely different experience—no suit jackets required.

But ultimately, it encourages me to engage in material and with people in the industries I train my students to aspire to become a part of. Once again, I have the chance to enrich and learn from a new network of stakeholders working with natural resources. I am excited to add more networks for my students to see that what we do in class isn’t just projects Rob likes. Well, I do—they just happen to be all connected, and I am lucky enough to work at an institution that aligns with both my personal and professional lifestyle.

I’m eager to get started. I hope my students are prepared for a little light summer reading about my journey, and I look forward to some new projects this fall. The Teacher at Sea excursion will fill some missing pieces in my curriculum and enhance our current projects through science and data analysis.

Preparing for My Mission

Preparing for this mission has been a surreal experience—mainly because I can’t believe it! To be honest, it’s been a little stressful. It’s been a flood of discovery, and often, unexpected uncertainty. It’s been hard to balance the wave of excitement, the fear of school starting upon returning, and wondering if I passed the medical and security clearance. I think the most challenging part was remaining present and not thinking about what’s to come. The anticipation and quest to be both mentally and physically competent were tried throughout the summer. But throughout the summer, I realized that all I had done in the last 14 years was new to me; this was going to be familiar and different—yet at the same time, very different.

Hull Number: R332
Length: 170.00 ft
Range: 3800 nautical miles
Endurance: 33 days
Speed: 11.00 knots

Part of my preparation involves reading about where I will be sailing and what I will be doing while at sea. I’ve been going down a rabbit hole of all things about the Oregon II, sharks, red snapper, long-line fishing, and the geography of the area. I am excited to be part of this exceptional place-based learning experience.

Between all that literature and content review, I bought a car with my partner and toured the East Coast, attending some live music shows. I hit places I love: Charleston, Philadelphia, and Saratoga Springs. Just before my mission, I will be spending some time on the West Coast in San Francisco. Although this doesn’t seem like much preparation, it’s been vital to get some respite after a long and successful school year. My partner is also an educator, and we’ve become quite skilled at managing our time during summer break. My bags have been mostly packed all summer and just need to be swapped out for gear for my Teacher at Sea experience. In all honesty, I’m probably packing the most efficiently for this trip. The Teacher at Sea packing list made my life simpler than I was making it—that’s for sure. I generally overpack for any journey, especially when it involves time at sea; following directions is typically a safe bet when it comes to the sea.

I’ve spoken to a TAS alumnus who sailed on this same mission, and it was beyond helpful. Talking to people has been the most beneficial. I have some friends in the business: one is involved in NOAA fisheries enforcement, another is a commercial fisherman, and a longtime mentor of mine was also a Teacher at Sea. These folks have shared valuable insight on dealing with life at sea. Always good to ask for help.

Dissection of Drifter Buoy

I am most excited about and have been preparing to participate in NOAA’s Adopt-a-Drifter Program. As it states in the Global Drifter Program: “A drifter, or drifting buoy, is a piece of scientific equipment that measures sea surface temperature, but most are also equipped to measure other variables. As the drifter moves around, guided by ocean currents, measurements of atmospheric pressure, winds, wave height, and salinity can be taken. This data is collected by sensors in the drifter and transmitted to overhead satellites. Tracking the location of drifters over time allows scientists to build a profile of ocean currents.” I’ve been reviewing some of the data and starting to think about all the exciting ways this can support my curriculum to be more real-life and data-driven.

After my Teacher at Sea journey, it’s back to the classroom. Between summer travels and some preparation for the new school year, my time has been taken up. I work with several partners who will be supporting our students next year. From designing an advocacy project with the Newtown Creek Alliance to participating in work-based learning experiences with Brooklyn Coffee Roasters, it has been exciting to consider how Teacher at Sea experiences will enhance these initiatives and help connect the dots. Brooklyn Coffee Roasters is even sending ten pounds of coffee for this mission!

I’ve been mentally preparing by remaining humble and open-minded about what’s to come—a practice I need to adopt every August as the new year approaches. I just need to start that mental gymnastics a little earlier and take a breath.

I am excited to travel to Miami to catch up with family and friends before departing, celebrating my departure, and officially entering middle-aged territory. Particularly my grandfather, someone who has been a part of my Renaissance-like knowledge loop in my life. It’s been nice to see him this summer, and it will be good to see him before he leaves the dock. What better way to celebrate life and my career than by going on this experience to once again be a student? I’m eager to learn and fill some knowledge gaps I have.

And honestly? I’m also just trying to prepare for how much I’ll miss my cat.

Thanks for reading about my journey that inspired me to apply to Teadher At Sea. Life isn’t linear, and I’m excited to learn further from those who are sure, and where the wind takes us.

Fair Winds. Stay tuned for more blogging while at sea.

P.S. Shout out to Tiffany Duong, an Author from EcoWatch, for giving me pointers on taking photos and writing a blog.

Science and Technology Log

To date, we have caught, tagged, and fin-clipped silky, sharpnose, sandbar, tiger, great hammerhead, blacknose, nurse, and scalloped hammerhead sharks. We have also brought up red snappers, a pale spotted eel, and a blunt-nose lizardfish. I have never seen any of these fishes before, so it has opened a whole new world of sea creatures for me. I am grateful to have this opportunity to explore a region of the ocean with which I am unfamiliar.

Personal Log

Living on a ship is much different than living on land. Obviously, we’re on a moving vessel, so the scenery and location are different every time we wake up. As soon as the mooring lines were cast off, we had no access to shopping for anything that we might have forgotten… 

One major change from when I was last aboard a ship 25 years ago is the internet. Thanks to a satellite connection through Starlink, I can now stream movies, call my husband, and scroll through Facebook — even miles from shore. It’s strange but comforting to feel connected to the outside world while being so physically remote.

Our living quarters are compact and communal. On the main deck where we fish, there’s a toilet and sink, while the lower deck — where we sleep — has two water closets with an adjacent sink. Each stateroom also has a small sink, which makes washing up and brushing teeth a bit easier. For showers, we have two shared ones for the entire crew, so we limit ourselves to ten-minute showers to make sure everyone gets a turn and can get to bed soon after their shift.

Before leaving port, the crew was split into two watches: day watch (12 noon to midnight) and night watch (midnight to noon). Most staterooms house two people on opposite watches, so the person off duty has the room to themselves while the other works. Unfortunately, our bunks are located just below the deck where the fishing line is hauled in, so it gets quite noisy. Sleep is something we grab when we can, knowing it may be disrupted by the sound of the winch or the motion of high seas. I’m on day watch, so my schedule feels more natural — but for those on night watch, sleeping during daylight and staying alert all night is a real challenge.

Yesterday we also launched the second drifter. This one had Falmouth High School stickers, of course, but also the crew of NOAA Ship Oregon II wrote their names, drew, or wrote favorite quotes. It was fun to get everyone on the ship involved in this project! The track of Drifter #1 appears to be keeping up with the ship!

Interview with Trey Driggers

Trey, wearing a life vest and work gloves, stands on deck with his right hand on the rail of the ship and his left resting on a white barrel lined with circle hooks. Behind him, the sky is blue with many gray clouds, and the water is blue-gray with some chop.
Dr. Trey Driggers hauling in hooks during our longline survey.

Trey Driggers is the PI, or principal investigator, of the Southeast Fisheries Science Center Bottom Longline (BLL) Survey. He originally wanted to be a musician playing guitar, but his father said that if he went to military school first, he would pay for college. That seemed like a good deal, so he completed an associate’s degree at Valley Forge Military Academy in Wayne, PA, then continued for a BA in History from Clemson University. 

Trey imagined being a lawyer, but he was always interested in sharks. His fascination with large predators was driven after his childhood dog was eaten by an alligator in his grandparents’ yard in Florida. He was 8 years old when the movie Jaws came out, and although he was too young to see it, he was intrigued by all the shark-related merchandise that was on the shelves at that time. During his senior year in college, scientists from the Smithsonian Institution’s National Museum of Natural History released a book entitled, Sharks in Question: The Smithsonian Answer Book. The last section was entitled, “How Do I Become a Shark Specialist?” He read that and thought, “That’s a job?” His career goals dramatically changed; now he realized that he could be a shark biologist. After graduating from Clemson, he enrolled in the courses needed to earn another degree in Marine Science. Once Trey had this focus, he became a straight A student. He finished that program in two years.

After finishing his coursework in marine science, Trey applied for graduate school and was accepted into Dr. John Dean’s lab at the University of South Carolina. Dr. Dean was very supportive of his students and is considered one of the godfathers of otoliths, studying ear stones of finfish to determine their age. Trey’s master’s thesis was on the age and growth of yellowfin tuna. Dr. Dean convinced him to stay in that lab to complete his PhD, as well. Part of his research on blacknose sharks required him to collect fin clips from sharks for a genetic study which was done in part on the Southeast Fisheries Science Center’s Bottom Longline Survey, which solidified his desire to work for the National Marine Fisheries Service. He has been participating in this survey since 1999. The rest is history!

Tell me about your family:

“We live in Ocean Springs, MS. My wife is a biology teacher in middle school. We met at USC and are both Clemson Tigers. We’ve been married for 26 years and have three children: Amelia is a biomedical engineer; Boyd is a junior at Ole Miss; and Max is a senior in high school. We have a malinois dog named Lilah and a chihuahua named Oliver.”

How did you get your position at NOAA Fisheries?

“In 2002 I was still a post-doc, but I went to the Resource Surveys Branch Chief at the Pascagoula lab three separate times to ask for a job. I think I finally wore him down and was hired in 2003. In 2012, I became the Shark Unit Leader. Kristin Hannan is my right-hand partner, and Will Tilley complements us both to make a solid team.”

What is the most fun part of your job?

“There are many fun parts of my job. My coworkers and I are very close, and it’s great being around people who have the same interests. I get to see things very few people get to see and I feel very fortunate to have access to the resources that allow me to conduct broad scale research. When I retire, I will know I did exactly what I set out to do and will have achieved my professional goals.”

What is the most difficult part of your job?

“I miss important family events such as birthdays, first days of school, etc. The good definitely outweighs the bad, though. Our work helps conservation and fishermen. I feel it’s critical to have boots on the ground when conducting research and in my field there is only one place to do that and that is on the water.”

What part of your job with NOAA did you least expect to be doing?

“I least expected the Deepwater Horizon disaster. When that happened, we were told, ‘You’re now forensic biologists,’ and our jobs changed significantly for a time. It was a big adjustment, and a massive effort by many, many people.”

What would you be doing if you didn’t work for NOAA?

“I’ve thought about that a lot and don’t have a good answer. I do play my guitar 3-4 hours per day, though, and would try to do something with that.”

Did You Know?

Scientists have identified ten different species of hammerhead sharks. We are fortunate to have caught two different species so far!

Science and Technology Log

“Fish on!” is what is called out whenever we have a fish on a hook. Everyone springs into action to collect data on the fish as efficiently as possible so it has a better chance of surviving. Their success is evidenced by the number of shark tags that have been returned after this release. Wednesday we caught a large female tiger shark that had been tagged by scientists out of the Apex Predators Program out of the NOAA Fisheries Narragansett lab. Here is a link to the work they conduct in that lab: https://www.fisheries.noaa.gov/new-england-mid-atlantic/atlantic-highly-migratory-species/northeast-shark-research. We are awaiting information about the tagged individual (where and when it was tagged, how much it has grown since she was tagged) from scientists in Narragansett. 

NOAA Fisheries has been conducting the Southeast Bottom Longline Survey for 30 years! Scientists and crew participating in the survey have vital scientific data on sharks and finfish in U.S. waters from Cape Hatteras, North Carolina, to the Florida Keys and through the Gulf of America.

Each year, survey stations—randomly selected before each cruise—are sampled in both shallow and deep waters. Scientists and crew use standardized fishing protocols to collect data on abundance, distribution, size, sex, and maturity of captured species. For bony fish, they also remove otoliths—tiny calcareous structures in the ear—to count growth rings and estimate age, similar to how one might age a tree.

This long-term, standardized dataset is an invaluable resource. It provides critical baseline information about marine ecosystems, which is especially important when natural disasters strike. Managers can refer to this historical data to understand pre-disaster conditions and guide recovery efforts.

This leg of the Southeast Bottom Longline Survey includes several augmenters—crew members temporarily reassigned from other NOAA ships or roles to help out where they’re most needed. Their skills and experience are a welcome asset on board, especially during a time when a federal hiring freeze has led staff to pitch in across vessels.

Among the augmenters are NOAA Corps officers either in training or assisting with training, the ship’s chief steward, and members of the deck crew. Their flexibility and teamwork ensure the survey continues smoothly and safely.

Left to right: Josh with a barracuda he trolled off the stern deck; Chuck Godwin in the best hat; Sean reeling in the line at sunset.

Fishing operations on this leg are led by a capable and experienced Deck Department:

  • Josh Cooper, Chief Boatswain, has served on board for 3 ½ years.
  • Chuck Godwin, the lead fisherman, brings years of experience working aboard NOAA Ship Oregon II.
  • Sean Gronquist, a skilled fisherman, just celebrated his one-year anniversary on board this week.
  • Aaron Walton, a seasoned Lead Fisherman from NOAA Ship Bigelow out of Rhode Island, is augmenting the night watch team.
  • Malachi Olson, a contractor, is also supporting night operations as an augmenter.

During fishing operations, this team handles critical tasks: setting longlines, hauling them back in after one hour, and moving a specialized mesh cradle into place when large sharks are brought aboard. Their coordination and expertise are essential to ensuring the data collection is efficient, humane, and safe for both crew and animals.

Interview with Sean Gronquist

This interview is with skilled fisherman Sean Gronquist. He has been around the Atlantic Ocean his whole life, but on NOAA Ship Oregon II for a year. Growing up, Sean and his friends used to take all kinds of watercraft out into the Intracoastal Waterway around St. Augustine, FL, from a dock behind his house. He learned some basic mechanics from his friend, Jordan, who was able to fix 2-stroke engines on the fly when they were out on the water together. 

Sean graduated from the University of North Florida with a degree in anthropology and a dream to be an underwater “Indiana Jones.” He earned his captain’s license and worked as a charter fishing captain for 15 years, where the focus for him was locating the target species of his clients to catch whatever they requested, if possible. Sean literally helped customers check items off their bucket list (he runs Uno Mas Fishing Charters out of Stuart, FL). He could return to this profession if he ever needed to, but for now he finds joy in working toward the important goal of figuring out how many fish are off the southeastern coast of the US.

Why is your work important?

“We collect data that is used by multiple groups to set quotas or limits on fisheries. We’re one of the longest running surveys.”

What do you enjoy most about your work?

“Even during transits, no two days are the same. Straight up, I fish for the government. The fact that I found a job that pays me to do what I’m passionate about, you can’t beat it. I learn something new every day. “

What is the most important tool that you use for your job?

“My answer is simple: a sharp pocket knife comes in handy all the time. You can cut something, open things, all sorts of uses. “

If you could invent any tool to make your work more efficient and cost were no object, what would it be and why?

“It would have to be something to keep weeds off the line, a weedless spring to remove the sargassum weed from the trolling line. We fish off the stern when we have finished all that we need to do, and it’s a pain to have to pull in the lures all the time because they’re fouled with sargassum.”

When did you know you wanted to pursue an ocean career?

“I’ve always known I wanted that. I grew up on the water, so I just needed to figure out how to make a career out of it. I did marine mechanics on Yamaha engines at a guy’s shop but realized that the owner of the shop would always make a lot more money than I would. I did finish carpentry, too, but ultimately I decided to put down a hammer and picked up a wrench.

“My great grandfather was a merchant marine, and my grandfather was a See Bee in the Navy in Okinawa in World War II. It ran in my family, so I always figured I’d end up on a ship.”

Personal Log

I am having so much fun and learning so much on this trip. It’s always nice to interact with people who are like-minded about the wonder of the ocean. We have a range of people on this leg of the cruise (it takes 4 legs to sample all of the stations and regions). Here are the people on the day watch with me:

  • Trey Driggers, primary investigator for the project
  • Gretchen Kruizenga, survey technician (Ms. Fix-It!)
  • Tera Winters, survey scientist (and former veterinarian)
  • Evan Winters, volunteer entering college at West Florida University when we return

Everyone is pulling their weight (I always feel like I need to step up a little more, but I am trying to keep up at these new tasks) and getting along well. I will try to write more about these new friends in the future.

New Animals Seen

  • Spotted dolphins
  • Cannonball jellyfish
  • Lion’s mane jellyfish
  • Tiger sharks (large and small)
  • Sandbar sharks
  • Leech on the sandbar shark
  • Nurse shark
  • Bull shark
  • Sharpnose shark
  • Great hammerhead shark! (the other watch actually saw this shark, but they showed me the pictures! We are in competition now to see who catches the next hammerhead.)
  • Two large red snappers!

Did You Know?

Otoliths, or fish ear stones, are the densest part of a finfish’s body and are made of calcium carbonate, the same material as seashells. They are suspended in a liquid to help the fish to know which end is up and to sense vibrations.

Science and Technology Log

Before I begin, my friend asked if we have a streaming presence. Although we do not, NOAA supports a website that tells where NOAA Ship Oregon II (and the rest of the fleet) is located at this link: https://coastwatch.noaa.gov/cwn/apps/noaa-shipwatch.html. This week we are completing many stations off the Florida coast and have made it as far north as Cape Canaveral.

On Tuesday we launched our first drifter, from NOAA’s Adopt-a-Drifter (ADP) program. The deployment went off without a hitch. Soon we will be able to view its movements using the following link: https://adp.noaa.gov/trackadrifter/falmouth-high-school/. Oceanographers from NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) in Miami, Florida, set up this dashboard to eventually see all three drifters in the ocean.

Tuesday night at 2030 (military time for 8:30 PM), we began preparing the first longline of the trip! This process looked daunting the first time we did it, but I’m sure we will settle into a groove soon.

A longline is a series of baited hooks stretched out for a long distance (ours stretches for a mile!). The line is weighted down at the beginning, middle, and end and marked by flanking high flyers, or buoys with long poles and a flashing beacon on top of a reflective panel so the ship’s captain can return to retrieve the gear.

We set out 100 gangions clipped to the mile-long longline. The ship steams forward, and the bridge calls out every 1/10 of a mile (10, 20, etc.) to help the bosun pace the number of gangions along the mile-long line. A gangion is a fishing unit consisting of a metal number to keep track of the hook, a clip, a length of monofilament with a circle hook at the end, and a piece of bait (we used mackerel cut into thirds). A circle hook is used because the curve of the hook reduces the chances that a fish or sea turtle will swallow the hook (an event that often mortally wounds the fish because it is very difficult to remove, or it can hold a sea turtle underwater and may drown them ). The bait has to be double-hooked (pierce it twice with the hook) to secure it.

Once the 100th gangion is attached to the monofilament, the bosun secures a weight, the second high-flyer, and a separate floating buoy to mark the end of the longline. Then the timer begins: the longline soaks, or stays in the water, for an hour from the time the second high flyer hits the water to the time we retrieve the first high-flyer. Here is an infographic made by Stephen Kade, former Teacher at Sea from 2018:

an illustration titled Long Line Fishing on the NOAA Ship Oregon II. The ship is depicted at the (completely flat) surface of the ocean. in the foreground, the ocean surface is cutaway to reveal a view of a deployed longline both above and beneath the surface. two buoys with tall fins ("high flyer buoys") are tied to each end of a line that is weighted at the ends and middle to stay on the ocean bottom. short lines extending off the longline in two directions are labeled baited gangions. there are silhouettes of sharks all around. at the top, there are 10 lines of text explaining the steps for deploying and retrieving the long line.

We did not land any fish at our first station, but we have a long way to go! The night watch caught two sharks: one silky shark and one dusky shark. I can’t wait to see some on our watch!

I am enjoying being on the ship and meeting new people. I will be interviewing some of them for this blog, so you can see for yourself the diversity of careers needed to support a survey cruise.

Interview with LT Luke Petzy

LT Luke Petzy of NOAA Corps on NOAA Ship Oregon II.

LT Luke Petzy was one of the first members of NOAA Corps (National Oceanic and Atmospheric Administration Commissioned Officer Corps) we met, as he led the “Welcome Aboard” meeting for all new volunteers and crew. From the outset, it was clear that safety is a top priority on this vessel.

The meeting covered essential safety procedures and introduced us to the impressive array of equipment installed to ensure our well-being at sea. Located at the top of the ship is an EPIRB (Emergency Position-Indicating Radio Beacon), which is triggered to call for help via satellite if the ship is in distress. In addition, SARTs (Search and Rescue Transponders) emit radar signals to aid in locating the ship during an emergency. 

Each person aboard is assigned to a specific life raft and issued an EEBD (emergency escape breathing device) for use in smoke-filled or low-oxygen situations. Hard hats and work vests are mandatory when working on deck. It is reassuring to know that we are in capable and well-practiced hands, as they perform drills at the start of each leg of the survey. Here’s a closer look at LT Petzy’s background and how he came to serve in the NOAA Corps.

How did you become a part of the NOAA Corps?

I grew up in Methuen, MA, and graduated with a degree in Natural Resource Studies and Fisheries Conservation from UMass Amherst. I took a SCUBA course that culminated in a trip to Key Largo, FL, which really hooked my interest in fish and the ocean. After college, I moved to St. John, US Virgin Islands to work at an eco-resort, where I met my wife, Corie. We moved back to MA when I got a job as a fisheries observer out of Woods Hole to go out on different types of fishing boats. It was the coolest job, but also the most dangerous. The job had a very unpredictable schedule and no way to call home for a couple of weeks while I was at sea observing. It was a really great experience but also a tough lifestyle.

In 2015 I moved back to St. John with my wife. I got my captain’s license and taught scuba. In 2019 I got a job in Newburyport, MA, as a tow boat captain.

Later that year, I applied and was accepted to NOAA Corps training. This job has given me the ability to drive boats and be a part of scientific operations and have adventures. I am a NOAA diver and have to dive a certain amount per year to maintain proficiency.

Why is your work important?

My job is to navigate the ship. I also work with the science crew to plan trips to complete the surveys. I like working for an agency that promotes science, scientific integrity, and an environmentally focused mindset. My job supports these efforts. I am responsible for the safety of the crew and safety of the ship, and I take pride in that.

What do you like most about your job?

I like seeing the ocean in a way that many others don’t, in all its moods and forms. I get to see marine mammals and marine life during the surveys. It is a rewarding feeling after we complete a successful mission.

What is the most important piece of technology that you use in your job?

The radar and electronic chart display system are so important to know where we are, and to avoid other vessels. I have to add the depth sounder, too, to avoid shallow water. 

What do you think you would be doing if you weren’t working at NOAA?

I would put my captain’s license to use on ecotourism boats or work with schools to bring students out on the water.

Do you have any hobbies?

Scuba, woodworking, and playing guitar. I have my ukulele on this trip to practice.

Personal Log

Life aboard NOAA Ship Oregon II is comfortable and exciting. The scientific crew work twelve-hour shifts, so a lot of time is spent with four other people on my watch. Each person brings different strengths to the group and takes on a variety of roles and responsibilities when we are fishing. I will share more about that in my next blog.

Animals seen:

  • Flying fish (they don’t actually fly, but the ship’s movement definitely motivates them to scoot along or glide)
  • Brown booby (a seabird)
  • Barracuda! The fishermen troll behind the ship when their work is done, and this day they caught a barracuda. They did not keep it because the barracuda sometimes contains ciguatoxin, a toxin that causes ciguatera fish poisoning. We don’t want anyone to be poisoned on this trip!

L to R: Chief bosun Josh Cooper and skilled fisherman Sean Gronquist reel in the barracuda from the stern of the ship. Josh Cooper shows his barracuda catch to an excited group.

Did You Know?

Many sharks have only a few babies (called pups) at a time. Tiger sharks, however, can have up to a hundred! Their pups are often preyed upon by adult tiger sharks, including their mother!
