Science and Technology Log
For the first days of our journey, we will be traveling south from Pascagoula through the Gulf to the Straits of Florida. This means we will not be starting our survey work until later in the week. So for this post, I will be giving you some background information on the survey’s mission, our ship, and what I’ve learned about the maritime industry while staying in Pascagoula.
Mission
If you’ve ever been fishing you know that it is governed by very strict rules. There are short seasons when you are allowed to catch certain species, as well as limits on the number, sex, and size of fish you are allowed to take home. When it comes to fishing, it is important that we have an accurate picture of the health and abundance of fish stock to promote the health of our marine ecosystems. NOAA Fisheries plays an important part in this. The Shark/Red Snapper Bottom Longline Survey takes place in four stages/legs every year in late summer in the western North Atlantic Ocean. The team decides on specific areas to sample and they make records of everything they haul in. (More details on how this is done will come in later posts.) Because they visit the same region annually, the scientists can measure trends in the health and abundance of species across time.
NOAA Ship Oregon II
Our home and workplace for the next 17 days is NOAA Ship Oregon II. Its home port is Pascagoula, Mississippi where it was built at Ingalls Shipbuilding, which is still in operation today. This shipyard played an important role in World War II, as it built nearly 100 ships for the United States and British Royal Navy. Oregon II is 170 feet long. It has a beam (width at its widest point) of 34 feet and a draft (the distance from the waterline to the lowest part of the boat) of 14 feet.
You can follow Oregon II on Facebook at https://www.facebook.com/NOAAShipOregon2 to see the various types of missions its crew and scientists carry out throughout the year. If you would like to track Oregon II or any other NOAA vessel, you can use its unique identifiers (IMO Number 6728068 or MMSI Number 303976000) on a variety of marine vessel tracking websites.
For parents and teachers, this could be a great way to teach children about geography, transportation, and economics. You can “adopt” a ship and watch it travel the globe or track how long it takes a container of goods to travel to your nearest port from across the world. My hometown Baltimore, Maryland, has a “roll-on, roll-off” (Ro Ro Cargo) port that allows cars, trucks, farm equipment, and other vehicles to be driven right off the ships. Car-loving children might enjoy tracking how their favorite imported models arrive.

Maritime Career Focus: Shipbuilding
Are you interested in shipbuilding or know a student who is? While people zip around the world on airplanes, the majority of our goods still travel the way they have for millennia: on the water. Although technology changes, waterways are still vital for commerce and the demand for ships and those who build them is still strong. According to Fortune magazine, there is a shortage of 250,000 workers in the industry. Shipbuilding requires “workers from across nearly every skilled trade. Shipyards rely on welders, electricians, pipefitters, and machinists.”

Finally I get to see Oregon II up close! (Photo credit: William Tilley)
After spending two nights in Pascagoula, I boarded the ship Monday morning at 7:30. Although I was able to see the ship at the dock from the street the day I arrived, this is my first close up view of Oregon II. I have seen many pictures of it from the NOAA website and Teacher at Sea alumni blog posts, so it was kind of like meeting my favorite celebrity in person. I received a warm greeting from William (Will) Tilley, a NOAA fisheries biologist who has been my contact for pre-travel orientation. I was nervous about boarding and departure, but Will was so welcoming I immediately felt more at ease.
The first order of business was to find my stateroom (a bedroom on a ship) and get unpacked and settled in. Space is tight and I am sharing with another member of the science team, so tidiness is key. I received a mesh laundry bag with linens for my stay and made up my bed. I haven’t slept in a bunk bed since my days of sharing a room with my sister! I will be working the day shift (noon to midnight) and my roommate works the opposite shift so that we will each get time alone in the room.
The stateroom has two berths (a bed on a ship) and storage space for our belongings. The “EEBD” (Emergency Escape Breathing Device) helps you breathe in case of fire evacuation. This card reminds me what signals I will hear in case of an emergency, where I should muster (meet up with my team), and what my task will be.
After moving into my stateroom, I met with members of the crew and the science team for orientations and safety briefings. There are other volunteers aboard ship — mostly undergraduate and graduate students — and they assured me I was in for a lot of fun. Everyone has been friendly and welcoming.
Without other duties for the day, I had plenty of time to explore the ship and enjoy the views. I found a shady spot on deck and read a book on my Nook. (I’m on my second book since I left Baltimore two days ago!) I did not bring any physical books in order to save on space, but the ship has a small library. If you’re a big reader like I am, you know how cool it is to see somebody else reading a book you love. I had a moment like that as I looked through the books and saw that there is a copy of Men Against the Sea, part of the Bounty Trilogy by Charles Nordhoff and James Norman Hall. This is a classic true story of endurance and survival at sea. Seeing a story I love in the library is another way that I feel welcomed to the ship.
A true find in the library of the ship’s lounge.
A great moment this afternoon was when I saw my first container ship on water. I turn into a little kid when I see big working ships. Soon after the big news story of the Evergreen Evergiven running aground and blocking the Suez Canal in 2021, we had our own container ship drama in Chesapeake Bay. The Ever Forward (also an Evergreen ship) ran aground off Pasadena, Maryland in 2022 and I insisted on an outing to go see it. (Did I mention I like boats?)
A container ship came into view off the starboard deck.

In the evening, I witnessed a beautiful sunset over the water, which I had been looking forward to all day. I tucked into the ship’s lounge with some other science volunteers to watch a movie and write. Since our shift ended at midnight, we all dipped into the generous stock of snacks in the mess (dining room). I was nervous about how I would sleep but the cool, dark, and the gentle rock of the ship helped me sleep like a rock. Then in the morning, I got to enjoy some delicious coffee to warm my teacher’s heart. Today will be another day underway and it’s rainy with some thunder and lightning so we are staying indoors.

Did You Know?
Without roads, how do ships know how to get into port without running aground like our friend Ever Forward? Besides their charts and equipment, they also use a system of buoys called “lateral marks.” When leaving port, the ship will keep the green buoys to the starboard (right when facing the front of the boat) and the red buoys to port side (left side when facing the front of the boat). When returning, the colors will be reversed, giving way to a classic nautical mnemonic: “red right returning.”
Leaving the port in Pascagoula we pass through the navigational buoys.

About Me
Sailing in the Baltimore Inner Harbor in November 2025 with the schooner Lady Maryland in the background.
My name is Cheyanne Vanderdonckt and I am a special educator in the Baltimore City Public School System in Baltimore, Maryland. I have been teaching first and second graders at Moravia Park Elementary for 17 years. My favorite thing about my job — besides working with amazing children — is that I get to learn and try new things all the time. I am so excited to have been chosen to go on a wonderful learning adventure this summer aboard NOAA Ship Oregon II with the Teacher at Sea program! I will be participating in the Shark/Red Snapper Bottom Longline Survey departing from Pascagoula, Mississippi on July 27. I have been learning shark facts all year from a couple of my students who are very interested in the topic. When I told them what I would be doing this summer and they heard the word shark, they were in awe. I can’t wait to share my experiences with them!
Why Teacher at Sea?
I have been fascinated by the water and tales of seafaring from a young age. Most of my exploration took the form of voracious reading, but I also found ways to get in or on the water as much as possible. I spent the majority of my childhood in Florida, where I loved to canoe on the rivers with alligators sunning themselves on the shores. In the last couple of years, I have begun learning to sail with a local nonprofit that operates right in downtown Baltimore on the Inner Harbor. As I built my confidence on the water, I started to think about how I could help connect my students with the wealth of opportunities our waterfront provides — from recreation to scientific learning to marine careers.
Most of my students love science and the outdoors. They have the natural curiosity of childhood and they love hands-on exploration. Our lessons inevitably lead to them asking more and more questions. I love being able to say “I don’t know but we can find out!” when a student asks a question that goes beyond the set curriculum lesson for the day. This means that our work has sparked an interest or even a passion. That being said, I also recognize that I need to develop my own scientific literacy if I want to provide them with the highest quality science instruction. Every summer I take advantage of teacher trainings in science to build my own capacity in this area. When I learned about the Teacher at Sea program, I realized that this was the perfect opportunity for my professional growth that would also enable me to bring value experiences back to my students and the wider school community.
What I Hope to Learn and Bring Back to Baltimore
The famous Domino Sugars factory in Baltimore’s Inner Harbor. Having a working port in our city is a great opportunity to connect students with marine careers.
I talk a lot with my students about careers in science, technology, engineering and math (STEM). Information about STEM careers is now embedded in the math and science curricula. However, I notice that many of the pictures presented to students show people indoors, sitting in front of computers or looking at a test tube. We don’t have as many images of scientists working outdoors or engaging in heavier tasks. My students love to move around, be outside, tinker with things, and generally be active. I always emphasize to them how critical reading and writing are to scientific careers. But I also want them to know that being a scientist can be an active career that can involve working outside, going on adventures, getting dirty and engaging in satisfying labor. Because I am a special educator, I am also interested in finding the ways that my students’ different ways of experiencing the world can be an asset in the science of the future.
Having a firsthand experience of a research cruise will help me understand the skill sets involved and the possibilities that await my students. Although they are a bit young to fully comprehend all of the technical details (and — if I’m being honest — I may struggle with it, too!), they will be able to see the types of work that scientists and mariners do at sea. I’m hoping that my work experience will aid me in designing learning experiences that help them learn not just scientific concepts but the types of technical and physical skills needed to succeed in these careers. For instance, the ability to identify and sort different species of fish may be a specialized skill but it is built on the foundations of careful observation and pattern recognition. How can I bring my students engaging experiences that build these skills? How can I keep learning exciting and motivating so that they carry that wonderful curiosity and sense of exploration into their futures? How can I connect them with experiences of our natural world that inspire awe and wonder?
Packing My Bag and Unpacking Big Feelings
In the past couple of weeks, I have been getting more and more information about my upcoming research cruise: what to bring, tasks to complete before leaving, a map of the ship, my shift and room assignment. On a practical level, I am checking and double-checking my packing list. I have a grown son who lives overseas and I have taken over his bedroom as my staging area. I’ve also been digging through his old Boy Scouts camping gear for anything that might come in handy. (He won’t mind that I took his head lamp!) Of course, space is limited, so I must resist the urge to think that I can prepare for any eventuality with more stuff. That’s all part of the learning process. I’ve also met with a Teacher at Sea mentor who answered my questions and assured me that “excited and nervous” are both appropriate feelings at this point. I am feeling just like my students probably do before beginning a new year of school. As teachers, it is not enough to just focus on information. We also have to attend to the emotions involved in learning. Allowing myself to be a beginner at something new and challenging helps remind me that my students are also feeling this way when I ask them to try something new. The support I want right now is the support I need to be prepared to give them.
On Saturday, July 25, I will be flying to Pascagoula, Mississippi, where I will spend two nights before the ship departs on Monday, July 27. Although I lived on the Gulf coast of Florida for 22 years, I have never been to this area before and I’m excited to have a day to explore before I report to the ship. This spring I read The Gulf: The Making of An American Sea by Jack Davis to learn more about this amazing body of water. I learned about the artist Walter Anderson who spent a lot of time on Horn Island. There is a museum dedicated to his work in Ocean Springs that I may have time to visit.
Thank You!
Thank you so much for joining me on this journey. I look forward to sharing everything that I will learn and experience. Although I am the one boarding the ship, I have received so much support from my family, friends, colleagues and administrators that have made all of this possible. I am truly grateful for all of this.

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).
Large tiger shark that bent the hook and swam away before we could cradle and measure her. The top hook was straightened by the tiger shark on the left! Bottom hook for comparison.
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.
Great hammerhead shark waiting to be hoisted alongside the ship for tagging and measuring.
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!
Photos: decorations on Drifter #3, launched by Josh and Sean south of Cape Hatteras on Tuesday night.
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.
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 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?

Participating in the Shark/Red Snapper Longline Survey provided a porthole into several different career paths. Each role on board facilitated and contributed to the scientific research being conducted. Daily longline fishing activities involved working closely with the fishermen on deck. I was in awe of their quick-thinking adaptability, as changing weather conditions or lively sharks sometimes required a minor change in plan or approach. Whether tying intricate knots in the monofilament or displaying their familiarity with the various species we caught, the adept fishermen drew upon their seafaring skill sets, allowing the set and haulback processes to go smoothly and safely.

Even if we were on opposite work shifts, overlapping meal times provided the opportunity to gain insight into some of the careers on board. As we shared meals, many people spoke of their shipboard roles with sentiments that were echoed repeatedly: wanted a career that I could be proud of…a sense of adventure…opportunity to see new places and give back…combining adventure and science…wanted to protect the resources we have…
I had the opportunity to speak with some of the engineers and fishermen about their onboard roles and career paths. It was interesting to learn that many career paths were not direct roads, but winding, multilayered journeys. Some joined NOAA shortly after finishing their education, while others joined after serving in other roles. Some had experience with commercial fishing, and some had served on other NOAA vessels. Many are military veterans. With a name fit for a swashbuckling novel set on the high seas, Junior Unlicensed Engineer Jack Standfast, a United States Navy veteran, explained how the various departments on board worked together. These treasured conversations with the Engineering Department and Deck Department were enlightening, a reminder that everyone has a story to tell. I very much appreciate their patience, kindness, and willingness to share their expertise and experiences.

The ship had a small library of books, and several crew members mentioned reading as a favorite way to pass the time at sea. Skilled Fisherman Mike Conway shared several inspiring and philosophical websites that he enjoyed reading.
Lead Fisherman and Divemaster Chris Nichols:
In an unfamiliar setting, familiar topics surfaced in conversations, revealing similarities and common interests. Despite working in very different types of jobs, literacy was a popular subject in many of the conversations I had on the ship. I spoke to some of the crew members about how literacy factored into their daily lives and career paths. Some people described their family literacy routines at home and shared their children’s favorite bedtime stories, while others fondly remembered formative stories from their own childhood. Lead Fisherman Chris Nichols recalled the influence that Captains Courageous by Rudyard Kipling had on him as a young reader. He described how exciting stories such as Captains Courageous and The Adventures of Tom Sawyer inspired a sense of adventure and contributed to pursuing a unique career path. Coming from a family of sailors, soldiers, and adventurers, Chris conveyed the sense of pride that stems from being part of “something bigger.” In this case, a career that combines adventure, conservation, and preservation. His experiences with the United States Navy, commercial fishing, NOAA, and scuba diving have taken him around the world.
Echoing the themes of classic literature, Chris recommended some inspiring nonfiction titles and podcasts that feature true stories about human courage, overcoming challenges, and the search for belonging. As a United States Navy veteran, Chris understood the unique reintegration needs that many veterans face once they’ve completed their military service. He explained the need for a “tribe” found within the structure of the military or a ship. Chris described the teamwork on the ship as “pieces of a puzzle” in a “well-oiled machine.”
Led by Divemaster Chris Nichols, also the Oregon II’s Lead Fisherman and MedPIC (Medical Person in Charge), the team gathered on the bridge (the ship’s navigation and command center) to conduct a pre-dive operation safety briefing. Nichols appears in a white t-shirt, near center.
Chris also shared some advice for students. He felt it was easier for students to become good at math and to get better at reading while younger and still in school. Later in life, the need for math may resurface outside of school: “The things you want to do later…you’ll need that math.” As students grow up to pursue interests, activities, and careers, they will most likely need math and literacy to help them reach their goals. Chris stressed that attention to detail—and paying attention to all of the details—is extremely important. Chris explained the importance of remembering the steps in a process and paying attention to the details. He illustrated the importance of knowing what to do and how to do it, whether it is in class, during training, or while learning to dive.
Chris’ recommendations:

Skilled Fisherman Chuck Godwin:
Before joining NOAA, Skilled Fisherman Chuck Godwin served in the United States Coast Guard for fifteen years (active duty and reserves). After serving in the military, Chuck found himself working in education. While teaching as a substitute teacher, he saw an ad in the newspaper for NOAA careers and applied. Chuck joined NOAA in 2000, and he has served on NOAA Ships Bell M. Shimada, Pisces, Gordon Gunter, and Oregon II.
Echoing Chris Nichols’ description of puzzle pieces in a team, Chuck further explained the hierarchy and structure of the Deck Department on the Oregon II. The Deck Department facilitates the scientific research by deploying and retrieving the longline fishing gear while ensuring a safe working environment. From operating the winches and cranes, to hauling in some of the larger sharks on the shark cradle, the fishermen perform a variety of tasks that require both physical and mental dexterity. Chuck explained that in the event of an unusual situation, the Deck Department leader may work with the Bridge Officer and the Science watch leader and step in as safety dictates.

In addition to his ability to make a fantastic pot of coffee, Chuck has an impish sense of humor that made our twelve-hour work shifts even more interesting and entertaining. Over a late-night cup of coffee, I found out that we shared some similar interests. Chuck attended the University of Florida, where he obtained his bachelor’s degree in Wildlife Management and Ecology. He has an interest in writing and history, particularly military history. He co-authored a published paper on white-tailed deer. An avid reader, Chuck usually completes two or three books during a research cruise leg. He reads a wide range of genres, including sci-fi, westerns, biographies, military history, scientific texts, and gothic horror. Some of his favorite authors include R.A. Salvatore, Ernest Hemingway, and Charles Darwin. In his free time, he enjoys roleplaying games that encourage storytelling and creativity. For Chuck, these adventures are not about the end result, but the plotlines and how the players get there. Like me, Chuck has done volunteer work with veterans. He also values giving back and educating others about the importance of science and the environment, particularly water and the atmosphere. Chuck’s work with NOAA supports the goal of education and conservation to “preserve what we have.”

Personal Log
Far from home, these brief conversations with strangers seemed almost familiar as we discussed shared interests, goals, and experiences. As I continue to search for my own tribe and sense of belonging, I will remember these puzzle pieces in my journey.
A high flyer and buoy mark one end of the longline.
My path to Teacher at Sea was arduous; the result of nearly ten years of sustained effort. The adventure was not solely about the end result, but very much about plotlines, supporting (and supportive) characters, and how I got there: hard work, persistence, grit, and a willingness to fight for the opportunity. Every obstacle and roadblock that I overcame. As a teacher, the longline fishing experience allowed me to be a student once again, learning new skills and complex processes for the first time. Applying that lens to the classroom setting, I am even more aware of the importance of clear instructions, explanations, patience, and encouragement. Now that the school year is underway, I find myself spending more time explaining, modeling, demonstrating, and correcting; much of the same guidance I needed on the ship. If grading myself on my longline fishing prowess, I measured my learning this way:
If I improved a little bit each day by remembering one more thing or forgetting one less thing…
If I had a meaningful exchange with someone on board…
If I learned something new by witnessing natural phenomena or acquired new terminology…
If I encountered an animal I’d never seen in person, then the day was a victory.
And I encountered many creatures I’d never seen before. Several species of sharks: silky, smooth-hound, sandbar, Atlantic sharpnose, blacknose, blacktip, great hammerhead, lemon, tiger, and bull sharks. A variety of other marine life: groupers, red snapper, hake, and blueline tilefish. Pelicans and other seabirds. Sharksuckers, eels, and barracudas.
The diminutive creatures were just as interesting as the larger species we saw. Occasionally, the circle hooks and monofilament would bring up small hitchhikers from the depths. Delicate crinoids and brittle stars. Fragments of coral, scraps of seaweed and sponges, and elegant, intricate shells. One particularly fascinating find: a carrier shell from a marine snail (genus: Xenophora) that cements fragments of shells, rocks, and coral to its own shell. The evenly spaced arrangement of shells seems like a deliberately curated, artistic effort: a tiny calcium carbonate collage or shell sculpture. These tiny hints of what’s down there were just as thrilling as seeing the largest shark because they assured me that there’s so much more to learn about the ocean.
At the base of the spiral-shaped shell, the occupant had cemented other shells at regular intervals.
The underside of the shell.
Like the carrier snail’s shell collection, the small moments and details are what will stay with me:
Daily activities on the ship, and learning more about a field that has captivated my interest for years…
Seeing glimpses of the water column and the seafloor through the GoPro camera attached to the CTD…
Hearing from my aquatic co-author while I was at sea was a surreal role reversal…
Fishing into the middle of the night and watching the ink-black water come alive with squid, jellies, flying fish, dolphins, sailfish, and sharks…
Watching the ever-shifting moon, constellations, clouds, sunsets, and sunrise…
Listening to the unique and almost musical hum of the ship’s machinery and being lulled to sleep by the waves…
And the sharks. The breathtaking, perfectly designed sharks. Seeing and handling creatures that I feel strongly about protecting reinforced my mission to educate, protect, and conserve. The experience reinvigorated my connection to the ocean and reiterated why I choose to reduce, reuse, and recycle. Capturing the experience through the Teacher at Sea blog reinforced my enjoyment of writing, photography, and creative pursuits.

In my introductory post, I wrote about formative visits to New England as a young child. Like so many aspects of my first glimpses of the ocean and maritime life, the Gloucester Fisherman’s Memorial statue intrigued me and sparked my young imagination. At that age, I didn’t fully grasp the solemn nature of the tribute, so the somber sculpture and memorial piqued my interest in fishing and seafaring instead. As wild as my imagination was, my preschool self could never imagine that I would someday partake in longline fishing as part of a Shark/Red Snapper Survey. My affinity for marine life and all things maritime remains just as strong today. Other than being on and around the water, docks and shipyards are some of my favorite places to explore. Living, working, and learning alongside fishermen was an honor.
I was drawn to the sea at a young age.
This statue inspired an interest in fishing and all things maritime. After experiencing longline fishing for myself, I revisited the statue to pay my respects.

Water and its fascinating inhabitants have a great deal to teach us. The Atlantic and the Gulf of Mexico reminded me of the notion that: “Education is not the filling of a pail, but the lighting of a fire.” Whether misattributed to Plutarch or Yeats or the wisdom of the Internet, the quote conveys the interest, curiosity, and appreciation I hope to spark in others as I continue to share my experience with my students, colleagues, and the wider community.
I am very grateful for the opportunity to participate in Teacher at Sea, and I am also grateful to those who ignited a fire in me along the way. Thank you to those who supported my journey and adventure. I greatly appreciate your encouragement, support, interest, and positive feedback. Thank you for following my adventure!
Thank you to NOAA Ship Oregon II and Teacher at Sea!

Essentially two books in one, I recommend the fact-filled Under Water, Under Earth written and illustrated by Aleksandra Mizielinska and Daniel Mizielinski. The text was translated from Polish by Antonia Lloyd-Jones.
Under Earth written and illustrated by Aleksandra Mizielinska and Daniel Mizielinski; published by Big Picture Press, an imprint of Candlewick Press, Somerville, Massachusetts, 2016
One half of the book burrows into the Earth, exploring terrestrial topics such as caves, paleontology, tectonic plates, and mining. Municipal matters such as underground utilities, water, natural gas, sewage, and subways are included. Under Earth is a modern, nonfiction, and vividly illustrated Journey to the Center of the Earth.

Diving deeper, Under Water explores buoyancy, pressure, marine life, ocean exploration, and several other subjects. My favorite pages discuss diving feats while highlighting a history of diving innovations, including early diving suit designs and recent atmospheric diving systems (ADS). While Under Earth covers more practical topics, Under Water elicits pure wonder, much like the depths themselves.
Better suited for older, more independent readers (or enjoyed as a shared text), the engaging illustrations and interesting facts are easily devoured by curious children (and adults!). Fun-fact finders and trivia collectors will enjoy learning more about earth science and oceanography. Information is communicated through labels, cross sections, cutaway diagrams, and sequenced explanations.

Science and Technology Log
My students sent me off with many shark questions before I left for the Shark/Red Snapper Longline Survey. Much of their curiosity revolved around one of the most fear-inducing features of a shark: their teeth! Students wanted to know:
Why do sharks eat fish? How and why do sharks have so many teeth? Why do sharks have different kinds of teeth? Do sharks eat each other? What hunts sharks, besides other sharks?
And one of my favorite student questions: Why do sharks eat regular people, but not scientists?
Most people think of sharks as stalking, stealthy, steel-grey hunters. With a variety of colors, patterns, fin shapes, and body designs, sharks do not look the same. They do not eat the same things, or even get their food the same way. Instead, they employ a variety of feeding strategies. Some gentle giants, like the whale shark (Rhincodon typus), are filter feeders. They strain tiny plants and animals, as well as small fish, from the water. Others, such as the angel shark (Squatina spp.), rely on their flattened bodies, camouflage, and the lightning-fast element of surprise. Instead of actively pursuing their prey, they wait for food to come to them and ambush their meal. These suction-feeding sharks have tiny, pointed, rearward-facing teeth to trap the prey that has been sucked into the shark’s mouth. This video demonstrates how the angel shark uses clever camouflaging and special adaptations to get a meal:
Circle hooks are used in longline fishing. Each hook is baited with mackerel (Scomber scombrus).
Frozen mackerel (Scomber scombrus) is used as bait.
The circle hooks and gangions are stored in barrels. The hooks are attached to thick, plastic fishing line called monofilament.
All 100 circle hooks were baited with mackerel, but sharks also eat a variety of other fish.
The sharks we caught through longline fishing methods were attracted to the Atlantic mackerel (Scomber scombrus) that we used as bait. Depending on the species of shark and its diet, shark teeth can come in dozens of different shapes and sizes. Instead of just two sets of teeth like we have, a shark has many rows of teeth. Each series is known as a tooth file. As its teeth fall out, the shark will continually grow and replace teeth throughout its lifetime—a “conveyor belt” of new teeth. Some sharks have 5 rows of teeth, while the bull shark (Carcharhinus leucas) may have as many as 50 rows of teeth!
The sandbar shark (Carcharhinus plumbeus) usually has about 14 rows of teeth. They may lose teeth every ten days or so, and most sharks typically lose at least one tooth a week. Why? Their teeth may get stuck in their prey, which can be tough and bony. When you don’t have hands, and need to explore the world with your mouth, it’s easy to lose or break a tooth now and then. Throughout its lifetime, a shark may go through over 30,000 teeth. The shark tooth fairy must be very busy!

Similar to our dining utensils, sharks’ teeth are designed for cutting, spearing, and/or crushing. The tooth shape depends upon the shark’s diet. Sharks’ teeth are not uniform (exactly the same), so the size and shape of the teeth vary, depending on their location in the upper and lower jaws. Some sharks have long, angled, and pointed teeth for piercing and spearing their food. Similar to a fork, this ensures that their slippery meals don’t escape. Other sharks and rays have strong, flattened teeth for crushing the hard shells of their prey. These teeth work like a nutcracker or shellfish-cracking tool. Still others, like the famously fierce-looking teeth of the great white, are triangular and serrated. Like a steak knife, these teeth are used for tearing, sawing, and cutting into their prey.

Beyond their teeth, other body features contribute to a shark’s ability to bite, crush, pursue, or ambush their prey. The powerful muscles that control their jaws and swimming ability, the position of their mouth, and the shape of their caudal (tail) fin all influence how a shark gets its food. Unlike humans, sharks do not chew their food. They swallow their food whole, or use their teeth to rip, shred, crush, and tear their food into smaller chunks that the shark can swallow. No need to floss or brush after a meal: sharks’ teeth contain fluoride, which helps to prevent cavities and decay.
Some people may find it hard to swallow the idea that sharks aren’t mindless menaces, but shark encounters are quite rare. Sharks have many extraordinary adaptations that make them efficient swimmers and hunters of other marine life, not humans. Whenever sharks come up in conversation, I am careful to dispel myths about these captivating creatures, trying to replace fear with facts (and hopefully, curiosity and respect). Since sharks can’t talk, I’m happy to advocate for them. Despite the way sharks are negatively portrayed in the media, I assure my students that sharks far prefer to eat bony fish, smaller sharks, skates, rays, octopus, squid, bivalves, crustaceans, marine mammals, plankton, and other marine life over humans. Instead of fear, I try to instill awareness of the vital role sharks fulfill in the ecosystem. We are a far greater threat to them, and they require our respect and protection.
As storms and hurricanes tear across the Gulf of Mexico, causing destruction and devastation, my thoughts are with the impacted areas. Before my Teacher at Sea placement, I never thought I’d spend time in the region, so it’s interesting to see now-familiar locations on the news and weather maps. One of my favorite aspects of being at sea was watching the sky: recognizing constellations while fishing at night, gazing at glorious, melting sunsets, and observing storm clouds gathering in the distance. The colors and clouds were ever-changing, a reminder of the dynamic power of nature.
The sky was vibrant.

Watching the recent storm coverage on TV reinforced the importance of strong and accurate communication skills. Similar to a sidebar on the page, much of the supplementary storm information was printed on the screen. For someone who needed to evacuate quickly or was worried about loved ones in the area, this printed information could be crucial. As I listened to the reporters’ updates on the storm damage, aware that they were most likely reading from scripted notes, I was reminded of the challenge of conveying complex science through everyday language.

One might assume that a typical day at sea only focused on science, technology, and math. In fact, all school subjects surfaced at some point in my experience at sea. For example, an understanding of geography helped me to understand where we were sailing and how our location influenced the type of wildlife we were seeing. People who were more familiar with the Gulf of Mexico shared some facts about the cultural, economic, and historical significance of certain locations, shedding light on our relationship with water.
Fishing is an old practice steeped in tradition, but throughout the ship, modern navigation equipment made it possible to fish more efficiently by plotting our locations while avoiding hazards such as natural formations and other vessels. Feats of engineering provided speed, power, drinkable water, and technological conveniences such as GPS, air conditioning, and Wi-Fi. In contrast to the natural evolution of sharks, these artificial adaptations provided many advantages at sea. To utilize the modern technology, however, literacy was required to input data and interpret the information on the dozens of monitors on board. Literacy and strong communication skills were required to understand and convey data to others. Reading and critical thinking allowed us to interpret maps and data, understand charts and graphs, and access news articles about the red tide we encountered.
I witnessed almost every person on board applying literacy skills throughout their day. Whether they were reading and understanding crucial written communication, reading instructions, selecting a dinner option from the menu, or referencing a field guide, they were applying reading strategies. In the offices and work spaces on board, there was no shortage of instructional manuals, safe operating procedures, informational binders, or wildlife field guides.
Writing helped to organize important tasks and schedules. To manage and organize daily tasks and responsibilities, many people utilized sticky notes and checklists. Computer and typing skills were also important. Some people were inputting data, writing research papers and projects, sharing their work through social media, or simply responding to work-related emails. The dive operation that I observed started as a thoroughly written dive plan. All of these tasks required clear and accurate written communication.
Junior Unlicensed Engineer (JUE) Jack Standfast carried a small notebook in his pocket, recording the various engineering tasks he’d completed throughout the day.
Each day, I saw real-life examples of the strong ties between science and language arts. Recording accurate scientific data required measurement, weight, and observational skills, but literacy was required to read and interpret the data recording sheets. Neat handwriting and careful letter spacing were important for recording accurate data, reinforcing why we practice these skills in school. To ensure that a species was correctly identified and recorded, spelling could be an important factor. Throughout the experience, writing was essential for taking interview notes and brainstorming blog ideas, as well as following the writing process for my blog posts. If I had any energy left at the end of my day (usually around 2:00 AM), I consulted one of my shark field guides to read more about the intriguing species we saw.
Did You Know?
No need for a teething ring: Sharks begin shedding their teeth before they are even born. Shark pups (baby sharks) are born with complete sets of teeth. Sharks aren’t mammals, so they don’t rely upon their mothers for food after they’re born. They swim away and must fend for themselves, so those born-to-bite teeth come in handy.

Appropriate for older readers, the clever, comprehensive text offers interesting facts, tidbits, and trivia. The book dives a bit deeper to go beyond basic shark facts and knowledge. I’ve read hundreds of shark books, and I appreciated learning something new. The text doesn’t shy away from scientific terminology and concepts, such as phylogeny (eight orders of sharks and representative species). The facts reflect recent research findings on shark behavior. Lesser-known species are included, highlighting the diversity in body shapes, sizes, and specialized features. From a design standpoint, the aesthetically appealing illustrations are stylized, colorful, and engaging. Simple infographics provide explanations of complex ideas. Fact meets fiction in a section about shark mythology from around the world. The book concludes with a discussion of threats to sharks, as well as ocean conservation tips.
