Mission: Shark/Red Snapper Bottom Longline Survey, Leg 1

Geographic Area of Cruise: Western North Atlantic Ocean

Date: August 4, 2026

Latitude: 34° 20.659’ N

Longitude: 76° 35.444’ W

Weather Data from the Bridge: Southwest winds 5 to 10 knots becoming 10 to 15 knots in the afternoon. Seas 3 to 4 feet. Showers with a chance of thunderstorms in the morning, then a slight change of showers and thunderstorms in the afternoon.

Science and Technology Log

The survey is in full swing. Every day during our 12-hour shift we will arrive at 2-3 stations, and the night shift will do the same. The exact number depends on how far apart the day’s stations are, as well as weather conditions and how long haulbacks take. We work in the rain, but not if there is lightning. The distance between stations varies from about 10 to 50 nautical miles. (A nautical mile is approximately 1.15 miles on land.) Our exact speed varies with current and wind, but we generally travel at about 11 knots, which means 11 nautical miles per hour. We begin to bait the hooks for the next station about 15-20 minutes before we arrive. Then it takes about 20 minutes to deploy the line off the ship’s stern. As soon as we are done with that, a few members of the science team will go to the bow with the deck crew to deploy a device that collects data about the water column (more on that below). An hour after the line was set, we will begin to haul in the line.

What are we hauling in? In this part of the Atlantic Ocean, we are mostly catching sandbar sharks (Carcharhinus plumbeus). Other species include tiger sharks (Galeocerdo cuvier), nurse sharks (Ginglymostoma cirratum), and Atlantic sharpnose sharks (Rhizoprionodon terraenovae). As explained in my previous post, most sharks are hauled up using the cradle. In the cradle, length measurements are taken.

Why more than one measurement? Before this trip, I always heard about, say, a “six foot shark.” I knew that scientists use the metric system so we wouldn’t be measuring in feet and inches, but we are also taking 3-4 length measurements for each fish. These measurements have been standardized using parts of the shark’s anatomy as endpoints. This allows scientists to make comparisons across different specimens and field studies, but it also helps them check for accuracy. It can be challenging to get accurate measurements on a living, moving shark. In addition, some species do not have a fork in the tail or a pre-caudal pit. The measurements generally taken are the pre-caudal length (from the tip of the snout to the point where the caudal fin meets the body), the fork length (from the snout to the fork in the tail), and the total length. You can see these lengths on this helpful diagram from the Florida Museum of Natural History. As a scientist takes the measurements, a recorder stands by with a data sheet to write them down.

When we catch a small shark, we can measure and weigh it on the deck. However, there isn’t a practical or safe method for weighing a large shark in Oregon II’s cradle. Instead, weights can be estimated based on length. If you are interested in how much a shark of a specific length might weigh, you can use this handy calculator from NOAA: https://apps-nefsc.fisheries.noaa.gov/shark/ This could be a great activity for having a little fun with measurement for students! After using good measurement practices to get your height, type your height in inches or centimeters into the calculator to see how much you would weigh if you were a shark. (If I were a sandbar shark, I would weigh about 95 pounds.)

The most exciting part of a shark catch is getting to tag the shark. Shark tagging helps scientists study shark behavior, populations and migration. If somebody catches a tagged shark, they can provide updated information on its location using a phone call or a website with a form. The tags we are using look like a piece of yellow coated electrical wire rather than a big plastic tag. They are inserted into the body right alongside the shark’s dorsal fin. After making a short (less than an inch) incision in the skin, the tagger inserts the tip of the tag with a device that resembles a large metal hypodermic needle. It’s important for everyone to work carefully but quickly to reduce stress on the animal and the chances of anyone being injured. After tagging, the hook is cut from the shark’s mouth and it is lowered back down to the water to be released. I have been allowed to tag three sandbar sharks so far and it is awe-inspiring to be so close to these amazing creatures.

This is the first leg (of four) of the Shark/Red Snapper Bottom Longline Survey. On this leg, we are fishing off the east coast of Florida, Georgia, South Carolina, and North Carolina. On the next legs, they will be in the Gulf and will likely catch much more red snapper. Red snapper has been fished commercially in the Gulf since the 1840’s and by the 1920’s there were already signs of overfishing that led to regulation. Today, it is considered a sustainable seafood choice because it is responsibly managed in the United States. The annual survey conducted by NOAA Fisheries helps inform the process of establishing catch limits.

When a red snapper is caught, length and weight measurements are taken. Then the otoliths (ear stones) are retrieved. Otoliths are structures made of calcium carbonate that help the fish with balance and determining their position in the water. Otoliths of different species develop new layers at different rates. Marine scientists use the layers of the otolith to determine the age of a fish — much like counting the rings of a tree’s trunk. The fish is also examined to determine its sex and other tissue samples may be taken.

Maritime Career Focus: Survey Technician

Senior Survey Technician Gretchen Arndt is responsible for the scientific survey equipment on Oregon II. She has a bachelor’s degree in biological sciences with a marine focus from Florida Atlantic University. She worked as a field biologist and a field operations manager in the Florida Everglades. Marine biology is a competitive field that attracts many talented individuals. Gretchen says that driving and maintaining airboats and other equipment in the field helped give her the technical experience that led to her being hired by NOAA.

One of the pieces of survey equipment that Gretchen is responsible for is known as the CTD (for conductivity, temperature and depth). CTDs come in various designs and they are integral to the science of oceanography. The CTD can be used to retrieve samples of water for further analysis, as well. This device is deployed off the bow deck after each line is set. Getting the CTD into and out of the water is a coordinated effort between the bridge, the science team, and the deck crew. Gretchen also equips Oregon II’s CTD with a light and camera so that the science team can visually evaluate the seabed.

I feel like I could just look at the sea and the sky all day and night. Fortunately, we do have transit time between stations so I am able to spend some time gazing. At first I just see blue everywhere, but the longer and closer I look, the more colors I can pick out. In the reading curriculum we use in my school district we have lessons in which students spend time silently observing a work of art. They aren’t allowed to speak for at least a minute because it’s important to let everyone form their own impressions before they hear others’ ideas. I will definitely share some of my sea and sky photos with my class to have them look for as many colors as they can see.

Occasionally I see other ships on the horizon and sometimes I can make out some features on shore. When we passed by the Kennedy Space Center at Cape Canaveral, I could see the massive Vehicle Assembly Building. My favorite view, however, is when dolphins swim alongside the ship. Dolphins follow boats and ships for many reasons. They can ride the bow wave to conserve energy. As the ship moves through the water, it can also disorient smaller fish, making them easier to catch. It is very hard to catch the exact moment a dolphin leaps to the surface, but I took a video one night while a spotlight was being used to illuminate the water for hauling back the longline.

One thing I enjoy about being a teacher is that people often tell me what they were like as children at school. At least a couple of people working aboard Oregon II have told me tales of having trouble at school because they didn’t like to sit still or got bored easily. Like many teachers, I always loved school. But I know this is not the case for everyone. In education circles, we talk about the “hidden curriculum.” Success in school requires a set of skills and traits that have nothing to do with the academic content being taught and which can be really challenging for neurodivergent students, students with disabilities, and many others. But this does not mean they lack the intelligence or drive to learn. In fact, many of them have the type of insight and creativity that is needed to drive innovation. If schools can’t support them, we are all losing out on the unique gifts and talents they have to share. To that end, I am always trying to find ways to make learning hands-on and connected to the real world. Although there is time for quiet and reflection, most of the day should be active and even a little loud. I try to highlight ways that my students’ character traits and interests might lend themselves to different career paths. I’m getting so many ideas from watching people work aboard Oregon II.

In my opinion, one of the coolest jobs on board is that of Fisherman. Fishermen handle lines and operate equipment, including cranes (I’m jealous!), winches, and the anchor windlass. They work with the scientists during fishing operations and maintain the fishing equipment. On this survey we are using a longline, but the ship is also equipped with trawling nets. (In fact, the ship’s design is basically that of a fishing trawler). When a shark is in the cradle, fishermen operate the crane to haul it up, handle the lines on the cradle to help guide it into place, and help control the shark.

Lead Fisherman Sean Gronquist shared one of his hobbies with us after we caught a red snapper. He paints one side of the fish with a biodegradable ink and stamps it onto canvas to make a print. This preserves the size and details of the fish, and makes a beautiful piece of art. The Japanese name for this art is gyotaku. In my classroom, I use arts integration a lot in science and math. Arts integration is a method in which a lesson addresses both academic content standards and fine arts standards. It has been shown to increase student engagement and improve retention of learning. It’s also great fun. I’m really excited to share this cool art form with my students. It has a physicality to it that makes it more interesting than a photograph. It will also be a great starting point to talk about texture. If you’re interested in educational uses for fish printing, here is an article from Smithsonian Museum of Natural History: https://ocean.si.edu/conservation/get-involved/educational-uses-gyotaku-or-fish-printing

We have about a week to go in our survey and I am still enjoying every minute of my time on board. We had a couple of windy days that tested my sea legs, as well as my ability to sleep. Ships are very noisy in the first place, but the sounds increase as things start to slide around and doors knock around in their frames. Fortunately, I’ve got old hands to teach me tricks like stuffing bits of paper towel into drawers and doors to stop them from rattling. Nothing is as simple on a ship as it is on land, but that’s all part of the adventure.

Did You Know?

Although they are fish, many sharks give live birth. This means that some sharks have “belly buttons” that remain for a few months after birth. (If we come across a shark belly button I promise to share a picture!) Sharks also have two uteri. This year, one of my students was very excited to tell me that sand tiger shark embryos eat their siblings in utero and that checks out too. Although it may seem a little gruesome as a “fun fact,” it also helped us put things into perspective one day when he shared that he was in a bad mood because he had a fight with his sister. You never know when some scientific knowledge will come in handy!

Date: July 28, 2026

Latitude: 27° 04.803’ N

Longitude: 85° 14.792’ W

Weather Data from the Bridge: West winds 10 to 15 knots. Seas 2 to 3 feet. Waves west 3 feet at 4 seconds and south 1 foot at 8 seconds. A slight chance of showers and thunderstorms in the morning.

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.”

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.

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.

Cheyanne is holding the book up for the photo - we can just barely see her hand - in front of a well stocked bookcase. — 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?)

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.”

Mission: Shark/Red Snapper Bottom Longline Survey

Geographic Area of Cruise: Gulf of Mexico/Atlantic Ocean

Date: August 7, 2023

Latitude: 30°33.167’N

Longitude: 81°04.685’W

Air Temperature: 31° Celsius

Wind Speed: 12.01 knots

Rachel, wearing a navy blue NOAA Corps uniform, stands for a portrait photo next to a plaque on an exterior wall of the ship that reads: R.V. Oregon II, designed by R. H. Macy for U.S. Department of Interior Bureau of Commercial Fisheries, built by The Ingalls Shipbuilding (Company), a Division of Litton Industries, Pascagoula, Mississippi, 1967 — Executive Officer Lieutenant Commander Rachel Pryor

Navigating NOAA Ship Oregon II is at once one of the most important and complex tasks on board. It is in motion 24 hours a day and must have skilled individuals to keep the crew safe and accomplish the mission of the survey. I spoke with Commander Adam Reed, Acting Commanding Officer, and Lieutenant Commander Rachel Pryor, Executive Officer, about this task.

Oregon II operates on two engines with one propeller (prop). It has a controllable pitch prop. This means that the pitch of the blades can be changed in order to change speed or even reverse the direction of the ship. The rudder turns the ship to port or starboard. There are also bow thrusters that turn the bow one way or the other.

There are a variety of devices that the navigator uses to know where the ship is, and to stay on course. They have two different GPS devices, in case one goes out. Additionally, they have a magnetic compass as well as a gyrocompass.

A storm and cruise ship off near Jacksonville, FL.

There are two radar units to see where other ships are and to get detailed weather information. One unit is more precise than the other but may pick up rain storms which may interfere with spotting ships. The other unit will still work in that situation.

When navigating, it is important to not just maintain the correct heading but also monitor course over ground. Even though the ship is heading in the right direction it can be pulled off course by the water currents and winds. This is very important to keep in mind not only across long distances but also when approaching the high flyer to pick up the longline. They must approach at a 90° angle and then turn to follow the longline. This is a fairly precise maneuver that is affected by both wind and current.

One important factor affecting the operation of the ship is the weather. Careful consideration of any weather conditions must be factored into any decisions made. No one is allowed on the deck if there are winds of 25 knots or more, waves of 4-5 feet, or lightning within 25 miles. Weather information is always monitored through five different sources. Decisions must be made while consulting and comparing different sources of data.

Executive Officer Rachel Pryor explained that there are two types of weather patterns to keep in mind when considering operations. The first are small squalls, which can be fast moving and may have lightning. These squalls may keep moving in the same direction and you can calculate when they will arrive. But they can sometimes dissipate, change course, or stay where they are. There are also larger weather systems to consider. These tend to be slower moving but can have seas “kicking up,” increased wind speeds, and lightning. These may require seeking some sort of shelter or even docking at a port.

We are looking at map centered approximately on Brunswick, Georgia, extending south to the northern counties of Florida, north to Charleston, and west to about the border of Alabama and Georgia. The radar shows a storm system concentrated on the Georgia-Florida border with other storm patches in central Georgia. — Radar showing an approaching storm system.

Weather has impacted the survey several times during this cruise. One of the most memorable was when I was working my shift and we were told to expect a long delay due to the weather. After about 30-45 minutes we were told to go ahead and bait the hooks and lay the longline. It takes about 2 ½ hours to run a station from putting the first hook in, to pulling the last one out of the water. The weather was beautiful and the seas were relatively calm during the station. Within a few minutes of finishing, the winds began to kick up as a system approached. In my estimation, these were pretty amazing calculations by Lieutenant Commander Pryor who was Officer of the Deck (OOD) for the haul.

The other incident to include here was a larger storm system that we were told on a Tuesday would arrive on Friday. Sure enough, it did. We headed in for cover near Cape Fear, NC. In this case, all fishing stopped and we sailed in an oval pattern keeping the waves to the bow or stern as much as possible. This led to a work stoppage of about 36 hours. In both cases careful calculations were made to keep the crew safe and maximize mission success.

Meet the Crew: Taniya Wallace, Fish Biologist

Taniya Wallace is a fish biologist contractor on the science team here on Oregon II. Taniya hails from Ocean Springs, Mississippi, where she grew up and still lives. Her mother is a teacher and her father works in naval ship design. Taniya credits her 6th grade teacher with first inspiring her interest in science. She says, “Science challenged my mind and made me wonder how things worked.”

After graduating high school, she got a summer internship at the Gulf Coast Research Laboratory where she developed an interest in marine biology. Taniya attended Mississippi Valley State University in Itta Bena, Mississippi. She played softball for her university and they won the Southwestern Athletic Conference championship three years in a row! At Mississippi Valley State, she earned a degree in biology with a minor in chemistry.

Taniya sits at a desk, facing a computer with two monitors. The screen is too bright to make out. She holds a microphone from an intercom system up to her mouth with her left hand, perhaps ready to read out data or provide direction. — Taniya works on a computer

After college she was hired as a contractor during the Deepwater Horizon disaster working on small boats trawling for fish and crustaceans to gather samples for NOAA Fisheries Seafood Inspection program. This was a three month contract.

Next, she was contracted to work with NOAA for the Plankton Unit for the next four years. On the surveys, she worked with the team to collect plankton (microscopic organisms) in three different sized nets. Then, back in the lab, she sorted and identified decapods (crabs, lobster, shrimp) and red snapper.

In 2014, she moved to the trawl survey. In this survey, they pulled a large net behind the boat and caught a variety of marine animals. They sort, identify and record measurements on what they find on the boat. Back at the lab, they would identify unknown species. This included different kinds of fish as well as invertebrates. She explained to me that the science team uses only scientific names so, often, she may not know the common name of species she is cataloging.

Here on the shark and red snapper survey her computer and data entry skills are evident. She catalogs otoliths (ear bones) and other parts quickly and easily. I am not sure if patience, kindness and equanimity are requirements of her job but she, like the other members of the science crew, excels in these qualities. And, her shark handling skills are really impressive.

Personal Log: A very exciting haul!

Every day continues to be full of new experiences and animals. Yesterday, there was a haul which on paper would look pretty boring but it proved to be anything but. First, we brought up a royal sea star ( Astropecten articulatus), a beautiful hand sized star with cream colored feet, with orange edges filled by a deep purple band. I half expected Trey, our lead on the science team, to claim it for Clemson. (Go tigers! Or, is that LSU? Yes, there is a school rivalry playing out among the science team.)

Hook number 33 had a feisty seven foot nurse shark. The next shark, a nearly seven foot sandbar shark, was on hook number 43.

Hook number 49 had a baby tiger shark that was being pursued by a great hammerhead. The hammerhead was closing in on its prey when the gangion tightened and the tiger shark was hauled out of the water. I cannot say what was in the hammerhead’s brain, but it was certainly animated. For the next few minutes, it searched in vain for the tiger shark, circling and making several passes on the starboard side of the ship and showing its dorsal fin.

Confusion? Anger? We can only speculate but I can imagine how strange the situation was from the hammerhead’s point of view. “Just another second and then, yum. Wait… where did it go?” I know this is purely unscientific and I am anthropomorphising (giving human characteristics to animals) but it really was a sight to witness.

Now where did that darn fish go? I know its here somewhere.

Later on that same haul, we hooked into a large tiger shark. It is not unusual to see a shark sucker or cobia, maybe two, hanging out around the shark as we bring it in. We have even caught a shark sucker on a hook. But this tiger had at least 10 cobia following it in.

She was big and had no intention of getting tagged.

She broke the line, and we were not able to measure and tag her. In this haul, only one fish was landed, but each of those events excited all involved and will be remembered and shared long into the future.

Science and Technology Log

NOAA conducts the Shark/Snapper Longline Survey each year at the same time and place. It goes from July through September and surveys from Cape Hatteras, North Carolina, to West Palm Beach, FL, and the U.S. northern Gulf of Mexico from southwest Florida to Brownsville, TX. This is a longline survey and one mile of gear is baited and laid down for one hour.

When the line is reeled in, the science and fishing teams take them off the hooks and record data on the fish. The data gathered includes what species (kind of fish) are caught, if they are male or female, their age, weight and length. Additionally, the sharks will be tagged with a number and released.

The data collected will be used by NOAA to help manage the health of the fishery. It is one set of data that goes into deciding how many fish can be safely taken from the ocean each year. Without this information, fishermen might take too many fish to keep the population stable.

NOAA Ship Oregon II is the ship that is used to conduct this survey each year. It takes a lot of people working together to accomplish this. The crew of the Oregon II is made up of several teams. Everyone has a job as a part of the team to make sure everything works as needed.

The NOAA Corps are the officers on the ship. They are responsible for the overall operation of the ship and are in charge of navigation, steering and everyone’s safety. They work in shifts from the “bridge.”

The engineering team makes sure that everything is working properly. This includes the engines, electrical systems, fresh water and the all-important air conditioning.

The deck crew includes the professional fisherman who do boat maintenance, prepare fishing gear as well as handle the big fish.

There are two stewards who prepare our meals and keep the dining area clean. They keep us well fed with several choices available at each meal three times a day.

The electronics department has just one person who is responsible to make sure all of the technology is working properly. That is a very big responsibility on this ship.

Finally, there is the science team. That is where I fit in. There are four NOAA scientists and six volunteers. I am one of the volunteers. The other volunteers are all university students.

There are 29 people on board and everyone works on shifts. The ship operates 24 hours a day so all jobs must be done around the clock. Most teams have two shifts that each last for… you guessed it… twelve hours.

Personal Log

These first few days have been spent getting acquainted with the layout of the ship, learning the routines of life on the ocean and the people on the ship. The most striking feature is that there seems to be an incredible amount of equipment packed into such a small space. Everything a crew of 29 could need for three weeks, emergency equipment and replacement parts. Yet, in any one place, there is adequate room to move and work. I have a “stateroom” that I share with one other member of the science team. Each of us have a “rack” to sleep in, lockers and drawers for personal belongings as well as a fold out desk to work at. We also have a sink and mirror. All this in a room that is about 7’X10’.

Rarely are we both in there but there is adequate room when that happens. The “passageways” are narrow and it takes coordination to pass another crewmember. The “mess” seats twelve people, at most, so we have to eat meals in shifts.

There are three bathrooms and two showers available for general use. Showers should be short to preserve water as well as to make it available for others to use. There are three different “gym” areas with equipment to work out in. My favorite is the flying bridge where you can look out over the ocean.

Safety is a priority on board the ship. We start by using basic safety procedures while moving around the ship. While underway, the pitch (front to back motion) and roll (side to side motion) of the ship never stops. This becomes more or less pronounced depending on the weather. So moving through the passageways and doorways and especially on the outside decks, one must be careful to use a hand to keep their balance. The stairwells are narrow and steep but negotiable. When using stairwells always have 3 points of contact, that means use two hands and then a foot is the third point of contact.

Moving around comes more easily with time. No open toed shoes are to be worn except on the way to and from the shower. Safety equipment must be worn when working. We will be wearing hard hats, gloves, glasses and a work vest. The work vest looks a lot like a personal flotation device but flat. If you fall overboard it will automatically inflate. There is a lot of equipment and devices all over the ship for use in emergency situations.

firefighting equipment mounted on an interior wall: an axe (labeled "Oregon II"), a crow bar, a folded up fire hose. a red plaque on the wall reads FIRE STATION NO. 4. — firefighting equipment in case of emergencies

Fire extinguishers, AEDs, masks for smoke, and, of course, life rafts. We have to do drills to make sure that we know what to do in emergencies.

four people stand on the aft deck "decked out" in firefighting gear. they wear yellow fireproof pants and jackets, heavy black and yellow boots, large yellow gloves, black or white helmets, gas masks, some sort of backpack. the sky is bright blue with some wispy clouds and the ocean is fairly calm. — our firefighting team

He wears a Teacher at Sea hat and sunglasses. other survival suits and flotation devices rest on deck around him — That’s me in a “Gumby” suit for survival in case we have to abandon ship.

Now that we have departed Cape Canaveral, I’m enjoying the Florida coastline! It didn’t take long for Fisherman Josh Cooper to catch a Wahoo. He must have read my mind about plans for dinner.

Science Log

On Wednesday, August 31, 2022, NOAA Ship Oregon II departed Cape Canaveral and started a path along the Florida coastline headed to the Gulf of Mexico. All of us took another Covid-19 test before departure to keep everyone safe. We had to wait for 17,000 gallons of diesel fuel to load the vessel. I was surprised about the amount of fuel needed for our journey! Although my shift begins at 12pm, I have time to get adjusted since we haven’t made it to the 1st location. I included my students in the interviews with several shipmates. Heather Moncrief-Cox, Senior Research Associate, and Jim Patterson, Fisheries Biologist, sat with me while I logged into Google Meet during my 9th grade Algebra Math class. They seemed happy to answer the questions shown below and were patient with the students. Mrs. Ashanti Raymond, teacher at McNair High School, did an excellent job monitoring the students working while they took their turn asking questions in front of the screen.

On Thursday, September 1, 2022, the students from my Coordinate Algebra & Pre-Calculus classes interviewed Chuck Godwin, Lead Fisherman, and Collin Lynch, Chief Electronics Technician. Their careers & lives are quite interesting! We found out more information about the logistics of fisheries surveys, different careers, education & certifications. I appreciate them taking the time to talk to us! This experience helps me and others understand the purpose of research, safety rules, and how everyone’s part is important!

Table titled: Interview Questions for Teacher at Sea Program: Chuck Godwin, Jim Patterson, or Heather Moncrief-Cox. Table includes 18 questions, such as "When did you realize you wanted to pursue a career in science or an ocean career?" and "What are your normal job duties?" — **Interview Question suggestions for the students at McNair High School**

The carousel of pictures was taken while students logged into Google Meet to interview my shipmates. Many of the students took notes & emailed me their summary.

A slide titled "Interview with Heather Moncrief-Cox: Senior Research Associate Aboard NOAA Ship Oregon II." It features three images: two screenshots of students in a classroom looking at the camera, and one of Heather and Maronda sitting together in a room on the ship. Large speech bubbles containing quotes point to Heather.

McNair High Students Interview Jim Patterson, NOAA Fisheries Biologist aboard NOAA Ship Oregon II:

What was your most memorable moment at sea?

While I was doing my job a sperm whale came up from the water! It rolled over to the point where you could see its eye and we just stared at each other. It was so remarkable to me that I forgot to turn on my camera.

How does being at sea affect your family life?

I don’t have my own family so therefore that’s not a problem for me. I talk to and meet new amazing people all the time.

What advice can you give students?

Do whatever you are interested in and the work you do in the end will all be worth it! You’ll be happy that you did it.

What is rewarding about your job?

There’s so much that I’ve discovered over the years and new things that I’ve learned. The experience also is something that’s worth it, along with the view of the ocean and sights of the creatures.

How are environmental issues related to STEAM (Science, Technology, Engineering, Arts, and Math)?

STEAM applies to just about everything in life.

McNair High Students of Dekalb County, Georgia, interview Chuck Godwin, NOAA Lead Fisherman:

What certificates or degrees do you have?

I have a Wildlife Management Ecology degree and Multi-Management Certification.

How does your job affect your family?

When my kids were younger this would affect them because I would be gone 2 weeks to 2 months. They are grown now so not so much.

What was your most memorable moment at sea?

We caught a 27 foot basking shark.

What are some of the rewards with your job?

I like the long-lasting friendships and my shipmates are like a second family to me.

What are you looking forward to aboard NOAA Ship Oregon II?

I’m hoping to catch a record-winning great white shark.

Why is your research important?

I protect species and keep them going. I make sure they are okay.

Heather Moncrief-Cox: Senior Research Associate

McNair High Students of Dekalb County, Georgia, Interview Heather Moncrief-Cox, NOAA Senior Research Associate:

When did you realize you wanted to pursue a career in science or ocean care?

I’ve always wanted to do this ever since 3rd grade when I dressed up as a Marine Biologist. At 13, I started shark diving.

Why is your research important?

It’s important to do research because it allows you to learn information you might not have known before. You can also gather evidence or proof to contribute to the information you learned.

Heather makes sure data is recorded and tissue samples are stored properly for later research.

On Friday, September 2nd, 2022, the students in my Analytic Geometry class interviewed Fisherman Josh Cooper. He was very helpful with different positions on the deck. He explained his life at sea & talked about some of the fish he recently caught. Later during the week, he prepared ceviche for everyone with the fresh catch of the day.

What are your normal duties?

I maintain the deck, catch fish, and work where I’m needed.

How does your job affect your social life?

You have to know what you are getting into. I’ve been on the vessel for about 2 months. It’s a challenge and it’s all about knowing how to manage your time. NOAA is really good about giving time off.

On Thursday, September 8th, 2022, I interviewed my supervisor Trey Driggers & Fisherman Chris Love. I was able to use a Voice Recorder APP & my phone to capture the moments. Trey was very detailed with explaining the purpose of collecting the data & helped me increase my marine life vocabulary. Chris shared lots of sunrise pictures & we often compared photos between shifts.

McNair High Math Teacher of Dekalb County, Georgia, Interviews Trey Driggers: Supervisor and Chief Scientist:

“We collect otoliths (inner ear bones) from bony fish species that help the fish navigate near reefs. Then we send the samples to the Panama City Lab to determine the age of the fish. They compare the age & length to see how fast they grow.”

How do you keep the bait organized?

You have to go in order so the lines don’t get crossed. We put a total of 50 hooks with bait in each barrel. The last one in is the first one out. Make sure you put the hooks in the Mackerel bait twice to be more secure. Sometimes you’ll get pieces of the bait back or none at all. If we’re lucky, then we’ll catch a few fish. The numbers on the hooks help us stay organized too.

McNair High Math Teacher of Dekalb County, Georgia, Interviews Chris Love: NOAA Able-Bodied Seaman/Fisherman:

What challenges do you face?

Being away from home. Sometimes you miss out on things. If you play around and don’t pay attention, then you can get seriously hurt.

Do you have any memorable moments?

You get to go to different places and experience things away from home. You meet new people on the ships and ports you visit.

On Friday, September 9th, 2022, my students interviewed Lieutenant Commander, Aaron Colohan. He has a lot of responsibilities & made sure we were safe on the ship. He has a large budget of 1.2 million dollars with many factors to consider.

What are some rewards you get from your job?

I believe in what I’m doing. My reward is doing something for my country, the world, and the planet. This is an opportunity to work outside of the military for public good.

I have to work with 23-30 people a day and make sure they are happy in their environment along with me. I make sure they are well fed and safe with a $1.2 million budget.

On Monday, September 12th, 2022, I interviewed James McDade, Junior Engineer. I had to use ear plugs because the noise level is very loud on the bottom of the ship where the engine & equipment is located. It was very hot & the space was tight.

McNair High Math Teacher of Dekalb County, Georgia, Interviews James McDade: NOAA Junior Engineer:

What made you choose this career?

I got lucky because I was supposed to only work for 60 days, but I was offered a permanent position over 20 years ago. I had no idea. I’ve been able to travel and see beautiful places all around the Hawaiian Islands.

What challenges do you face?

What I do is maintenance. If anything breaks down, I repair it. I check the refrigeration, water leaks, engines, change filters, and pipe system. Before, it was easy to save money while at sea, but now due to online services I spend more.

Can you describe a memorable moment?

When I worked in Hawaii it was fun going to all the different islands and meeting new people. I also visited Taipan China & Guam. I enjoyed having fun in those places. The atmosphere is nice with everyone getting along.

Do you need a degree or certification for your career?

Yes, I went to training at SIU Piney Point Maryland. That’s where I picked up my last endorsement. I need one more license to be an official engineer. I have to study on my own & take the test.

What advice would you give students?

Check out the different careers. Keep a clean record because you are dealing with the government. You want to make sure you can travel, get a passport so you can see the world. I would also say learn how to work with people. You don’t have to like everybody but be respectful & know how to work together.

Personal Log

I am glad we are on our way to the Gulf of Mexico! The shoreline is gorgeous & the skyline is ever changing into patterns of colorful art. Soon I will no longer see land & view the ever-changing skyline. I’m excited that I get to share this experience with my students & colleagues while sailing. My shipmates work well together & are willing to pitch in wherever they are needed.
