Meet the Scientists!

Hi, I’m David Richardson! I live in South Kingstown, Rhode Island, but grew up in Sierra Madre, California. I studied Natural Resources at Cornell University, then went to grad school at the University of Miami. I’m the chief scientist on this cruise, which means I help plan how we collect data to meet our science goals. My research focuses on larval fish, fish migrations, and how ocean conditions affect fisheries. My favorite marine animal’s the sail fish. They’re beautiful at every stage of life! I love science because it helps us make the world better. In fisheries science, our work helps keep fish populations healthy so people can continue to enjoy fishing and have access to food.

Fun fact: My first research was on baby eels near Barbados. I discovered and illustrated six types of eel larvae that were new to science! That experience showed me how much of the ocean is still a mystery. My advice: Pay attention in math and writing but also get outside! Observing nature is one of the best ways to become a great scientist.

My name’s Allison Black! I’m from eastern Connecticut and often at sea. I studied Zoo and Wildlife Biology at Malone University and worked briefly as a zookeeper before focusing on ornithology. My favorite (yet unseen) marine animal is the Wandering Albatross. They can travel over 75,000 miles a year! On this project, I’m surveying seabirds and marine mammals. I love the ocean’s mystery and the chance to keep learning through different cruises. Fun fact: by year’s end, I’ll have 500 sea days! My advice: stay flexible, stay curious, and seize opportunities you didn’t know existed.

I’m Chrissy Hernández! I grew up in New Jersey and now live in Oxford, England. I earned my bachelor’s from Columbia University and my PhD from the MIT-WHOI Joint Program in Oceanography. I’ve worked as a researcher at Cornell and Oxford. I’m a population ecologist who studies biological oceanography and theoretical ecology. My favorite marine animal is the bluefin tuna! Aboard the ship, I help deploy plankton nets, identify tuna larvae, and guide sampling efforts. I love the ocean’s vastness and mystery, and how tiny organisms like phytoplankton produce half the world’s oxygen. Fun fact: I once shaved my head and tossed the hair overboard during an equator-crossing tradition!

Hi, I’m Autumn Moya! I’m from Colorado and now live in Silver Spring, Maryland. I studied Biology at Western Colorado University with a focus on environmental biology, and I’m finishing my Master’s in Coastal Science at the University of Southern Mississippi. My research models how offshore development might affect the Atlantic surf clam fishery. I’m currently a John A. Knauss Marine Policy Fellow with NOAA’s Office of Marine and Aviation Operations. I support communications, policy, and events. I’m excited to join research cruises like this one. My favorite marine animal is the cuttlefish. Did you know they can change color as fast as a blink? I’ve always loved the ocean, even growing up in a landlocked state. Since finishing my bachelor’s, I’ve lived in seven states! My advice to future scientists: stay curious and never hesitate to reach out. Science is for everyone!

Hi, I’m Amanda Jacobsen! I’m from Rhode Island. I studied Environmental Studies at Connecticut College and now I’m working on my master’s in Marine Biology at UMass Dartmouth. On this cruise, I help deploy nets and collect seawater to study the carbon in it. My favorite sea creature is the lumpfish. Look it up, it’s cool! I’ve worked on over 80 boats, and I love biology because it lets me explore the hidden world of ocean life.

Sometimes only visible under a microscope.

My advice to you: Stay curious and try new things, you might discover something amazing or meet someone who inspires you!

Hi! My name is Kristen Walter and I live in Miami, Florida. I graduated from the College of William and Mary with a master’s in marine science. I now work for the University of Miami/CIMAS studying coral reef fishes and bluefin tuna! My favorite marine animal is probably the nudibranch! I’m here on this cruise to help locate larval bluefin tuna, set and recover nets, preserve and identify fish, and test out new methods of capture using light traps. A fun fact about me is that I got to participate in the Aquarius Reef Base Underwater Habitat in Key Largo when I was in grad school. If you’d like to get into marine science, look for summer internships. Many places offer programs for high school students. Get your feet wet. Anything is possible!

Personal Log

Over the weekend, we moved back onto NOAA Ship Pisces. It felt nice to return after a few nights in a hotel while crew members got everything ready for our big mission.

view of computer screens, keyboards, mice on a wooden desk in an interior room of the ship — When we’re not setting things up, we spend time working in a place called the dry lab. The dry lab has computers, machines, and tables for us to study the ocean data we collect during the mission. I’ve been using this time to write my blog!

broader view of the dry lab: metal tables, a wooden desk, computers, computer chairs, two unidentifiable people sitting, facing away from the camera — Many scientists also bring their laptops, journals, or books to read or work on. It’s a quiet place where people come and go, but when it’s time to work, everyone jumps in to help!

three women - one seated at a desk, two standing - are in discussion. the seated woman holds up a piece of plastic film with her left hand. — Scientists Kristen, Chrissy, and Sarah are making sure the light traps for our drifters (for catching fish) are ready.

Just like we practice fire drills and safety rules at school, there are also important rules and practice drills in case of emergencies.

two people walk through a hallway of the ship toward an exit to an outer deck — Staying safe is super important when you’re out at sea.

a NOAA Corps Officer (in blue uniform) stands at the front of the mess hall and holds a breathing apparatus up; it blocks the view of his face. we can see the chair legs are capped in cut tennis balls to prevent them from sliding — Lieutenant Musick, one of the operations officers, is giving us safety training. He’s showing us how to use an EEBD (emergency escape breathing device).

The three scenarios also include depictions of the corresponding morse code, shown as boxes or rectangles — Outside of each stateroom, or everyone’s rooms, there is information on where you report to and what your role is during emergencies. It’s a good idea to study this information!

Sinh (right) and a woman (left) pose for a selfie with a dummy used in safety exercises — With our floaty rescue dummy!

Safety first! I need to make sure I can stay afloat in case I ever have to evacuate into the water.

I tried on an immersion suit, or “Gumby suit,” to make sure I can float in water. It’s also designed to keep people warm in the water in case they have to abandon ship or go into the water.

Sinh, wearing his Teacher at Sea baseball cap, poses for a photo - making a shasta sign with his left hand and with his right, grasping the bagged survival suit and personal flotation device. he is standing on an outer deck. — So far, I’ve really enjoyed getting to know everyone on board. I’m a lot more familiar with everything around the ship, including where all the rooms, crew members, and emergency equipment are. I’m feeling excited about our mission once we set sail.

Next time, I’ll be writing about a special tool we use called the CTD (Conductivity, Temperature, and Depth), which helps us learn more about the ocean!

Did you know?

NOAA ships have their own weather stations right on board. That means they can measure wind, rain, temperature, and more. Even while they’re sailing across the ocean! What do you think scientists do with that information?

Science and Technology Log

These are some of the people in my new neighborhood! There are many different jobs and career titles on board NOAA Ship Bell M. Shimada. It is an interesting learning experience investigating the human work that goes on at sea. The ship occupations are broken down into the following categories: science, engineering, ship management, NOAA Corps, survey technology, electronics, and stewarding. Today, I will be writing about the scientists.

Science

On the science side, many different scientists are doing fascinating work on board. Here I will review just a few. Many of the scientists have PhDs and work in the exact field they researched in their graduate studies. Sabrina, Zach, and Melissa are fish biologists. They work directly in the lab, counting, dissecting, and investigating the health, population, and biology of the fish.

Most of their work on this voyage is focused on two different types of fish populations: hake, and coastal pelagic species (CPS) (which include Pacific sardine, Pacific mackerel, Jack Mackerel, Northern Anchovy, Market Squid, and Krill.)

In addition to the biologists, we have a research economist, a software engineer, and a satellite oceanographer on board. These three scientists have volunteered to be on the ship for both the adventure and to get a better understanding of how their work combines with other NOAA research.

For example, Melina helped expand, adapt, and add functionality to a computer program called CLAMS: Catch Logger for Acoustic Midwater Surveys. The scientists work with this program in the wet lab to capture and record important data about the fish populations they are studying.

Personal Log

On the first day at sea, we practiced safety drills for fire/emergency and for the unusual occurrence of having to abandon ship. Being able to put on a survival suit is critical to an individual’s safety in the event of having to enter the water because it will protect them from hypothermia. In these photos, our crew is on deck and practicing drills to get into the survival suit. It is a bit like trying to put a chicken into a prom dress, but I managed to get it on with a little help and instructions from my crewmates.

Did You Know?

On board the NOAA ship Bell M. Shimada, there is a specialized acoustics lab that plays a vital role in scientific research. Currently, this lab is actively collecting meteorological, geophysical, and biological data from along the bottom of the Pacific Ocean. Meteorological data includes information about weather conditions, such as wind patterns, temperature, and atmospheric pressure. Geophysical data refers to the physical characteristics of the seafloor, including its composition, structure, and topography. Meanwhile, biological data focuses on the living organisms found in this underwater environment—particularly the fish species being studied. Together, this data provides crucial information concerning the ocean’s dynamic systems that propel scientific work.

Biological data is especially essential for the scientists aboard the NOAA ship Bell M. Shimada. To collect this information, the ship uses sound waves that are sent down into the water to detect fish. When these sound waves encounter schools of fish, they bounce back and generate an image on a monitor. Chief Scientist Rebecca Thomas explains that this process is similar to the echolocation used by dolphins to navigate and locate food in the ocean.

Expanding on this, research fish scientist Steve De Blois describes how the resulting acoustic map helps identify different species. For example, hake appear as a green, wavy snake deep in the epipelagic, or sunlight zone; rockfish resemble haystacks near the seafloor; and coastal pelagic species (CPS) show up as a red ball closer to the surface.

Since the Shimada is focused on fish research, the scientists rely heavily on this acoustic technology to locate and study their target species with precision.

Science Log

Let’s talk about how Popoki, the autonomous underwater vehicle (or AUV), ‘converses’ with the AUV pilot aboard the ship. The map and directions for the route Popoki will be mapping is programmed into her computers ahead of each dive. On this mission, Popoki has been deployed daily, so every evening, the scientists carefully plan out where she will go on each deployment. They also plan the path Popoki will go when on location – this cruise she has made a lot of sawtooth-shaped patterns to give the scientists the greatest survey of what is in the areas they want to study.

photo of a computer screen showing, at center, an image from a computer-generated model of the underwater bathymetry of an area. Overlaid on the image are topographic lines and depth numbers. overlaid on that is a zig-zagging white line showing Popoki's route. — *Of course, tomorrow’s dive pattern is not a sawtooth pattern. The pattern is drawn out in the white lines over the diagram of the ocean floor contour.*

Though this seems like it would be easy to set up Popoki and let her run her course, that is not quite the end of the story. During a dive, the ocean current is sometimes unknown in any given area, so the AUV pilot needs to be able to help Popoki adjust her positioning. It would not be a very big help to get pictures of an entirely different area than the scientists were aiming for because the ocean currents took Popoki to a different area of the sea floor. The scientists also need to be able to help Popoki if she gets stuck on fishing line, or if the conditions above the water change – such as weather changes or vessel traffic – that would require Popoki to surface ahead of her scheduled time.

To communicate with Popoki, an acoustic modem system is used. There is a modem aboard the ship that can send messages to Popoki through a series of chirping sounds. The pitches and lengths of the chirps are all part of the code that Popoki can understand. She has a device that ‘listens’ for these sounds and can then follow the coded instructions to alter her pre-programmed course. She also communicates regularly with the AUV pilot – sending the coordinates she believes she’s at, her depth, battery life, and how many pictures she has taken so far in the dive.

Popoki’s communication device points upward, so when deployment is taking place, the scientists place a transducer into the water to use to communicate. Once Popoki is on her way to her programmed starting point, and farther away from the ship, the transducer is removed from the water.

crewmembers, wearing hard hats and life vests, lean over the rail of the ship and use hooked poles to guide a small yellow object suspended from what looks like a fishing pole safely down toward the water's surface. — *This is the transducer that is placed in the water for deployment*

Sometimes there are difficulties with this communication, and this is where the ship’ crew plays a very important role. The officers on the bridge work to position the ship in areas that allow for Popoki and the acoustic modem to speak to each other easily. The angle of the ship will change as Popoki goes through her programmed patterns, adjusting so that the chirps of the modem have a direct line to Popoki. Distance also plays an important part of the communication process – if the ship and Popoki are too far away from each other, there can be interference with the communication. Ocean current, wave heights and lengths, and other sounds coming from the ship can interfere with the communication, as well. The AUV pilot and the ship’s crew work very closely together throughout the entirety of the dive to help the Popoki and the pilot have clear communication.

At this point, you may be wondering WHY do we use Popoki. I’m sure that you can see her benefits in exploring areas we have not yet seen, but the why actually goes much deeper than that (no pun intended). One of the first things Popoki is doing is looking at areas that are being considered for future offshore wind farm sites. There is a great interest in putting wind turbines over the ocean to create renewable energy for our country. Having been on the Pacific Ocean for 2 weeks now, I can definitely attest to the fact that the wind is very strong in these areas, so there is plenty of energy to harvest. Popoki is identifying the deep sea habitats and geological features on the seafloor that would need to be considered when anchoring any wind turbines.

Popoki is also looking at the changes to the habitats as a result of different regulations that have taken place in fishing areas in this region. Some of the locations we have visited were mapped out by Popoki in the past, and scientists are looking to see whether fishing regulations have helped the populations of ocean life return. Finally, Popoki has been looking for evidence of seeps in the ocean floor. These geological areas are spots where cracks in the ocean floor have occurred due to plate tectonics.

Personal Log

The ship’s crew spends a lot of time preparing for safety. Just like we have fire, tornado, and lockdown drills in our school, the ship has drills to practice for emergencies as well. They need to be ready for any emergency, and everyone has a role to play. We have practiced the drills each week.

Throughout my time on NOAA Ship Bell M. Shimada, I have gotten to experience some pretty amazing things. However, my absolute favorite moment was getting “Helm time.” That’s right – I got to drive the ship! With Ops Officer Lieutenant Jaime Hendrix and Ensign Megan Sixt guiding me, I got to turn the ship to hard rudder, causing her to drive in a circle. I also got to get her back to her appropriate heading for the transit we were making, and then practice keeping her on course. It was really interesting to see how the ship reacts to the controls and to see what she does! I am so grateful to CO Laura Gibson for this opportunity, and really appreciate the help LT Hendrix and ENS Sixt gave me!

We practice where to gather, or ‘muster,’ in the event of a fire or abandoning ship. At the very beginning of the cruise, we get right to work with a tour of where to find the lifeboats, how to deploy them, and then we get to the drills.

Recently, I had the opportunity to learn to use the flares and the line thrower. The line thrower is used for ship to ship transfers or for rescuing someone who’s fallen overboard. Although it is really fun to get the experience to use these devices, it is definitely something that you hope only gets used in training. However, knowing they are there and that everyone knows how to use them makes you feel a bit better if an emergency does happen.

Lisa, wearing very large, thick gloves, poses near the ship's railing and smiles at the camera. in her left hand, over the railing, she holds a lit flare. it's a mostly clear day, and the sky is blue with a few clouds, and the ocean has a few whitecaps. — *I now know how to use the flares!

Music Connections

Communicating with Popoki has a lot to do with acoustics. Listening to her pilot talk about how important the angles between Popoki and the ship are reminded me a lot of preparing for a recital when I was a music education student at UW-Whitewater. As an undergraduate, we had several performance requirements per semester. For solo performances, the more experienced music majors would always pass on a very important piece of acoustic information to the new undergrads – always aim the trombone bell at the 3rd exit sign along the stage right wall. Hitting this sweet spot would cause the recital hall to ring, the trombone sound to be dark and full, and the experience to be the best for all who were listening. New trombone majors learned very quickly that this was not a piece of urban legend, but by bouncing the brass sound off of the wall at this angle, it was much more pleasant for the audience than to play directly at their faces.

view of an empty performance hall — *The beautiful Light Recital Hall at the University of Wisconsin-Whitewater – a great place to perform and explore acoustics! (Photo credit: Dr. Glenn Hayes*)

Communicating with Popoki is similar in a way – rather than bouncing her communications off of corners and walls, however, she responds better to the sound waves coming directly at her. She has a sweet spot, too, but it is more about decreasing the angles. This is a much more efficient method of communication for her, because she does not care about the timbre of her chirps!

Another great moment I really enjoyed during our time together was helping our Chief Scientist Dr. Clarke learn ukulele! I always believe that music is everywhere, and Dr. Clarke proved that theory again for me by bringing her ukulele along on this cruise when she heard the Teacher at Sea was a music teacher! Hopefully she had as much fun as I did!

In the computer lab, Lisa and Dr. Clarke sit in chairs facing one another. Lisa, smiling, leans forward to hold up an open laptop where Dr. Clarke can see it easily. Dr. Clarke watches the screen as she picks at her ukulele. — *Dr. Elizabeth Clarke showing off her virtuoso skills with a little “Hot Cross Buns” (Photo credit: Alice Kojima-Clarke*)

Sounds from the ship today will feature the sound of the ship’s engine outside from the very top deck of the ship.

This is the sound of the engine humming from the Fly Deck. You can also hear the waves, as we are in transit to our next station!

Student Questions

St. Bruno students are fascinated by sea creatures, and they have sent me on a quest to learn about the octopus. I think they will be very excited to see this picture and learn about the deep sea octopus!

You can see the octopus’s eye sticking out! (Photo credit: Popoki*)

Final Notes

The NOAA Teacher at Sea Program is an incredible opportunity for any teacher. As you can see, you do not need to be a science teacher in order to apply. There are so many connections to be made with the ocean, and students get really excited about learning through their teacher’s experience. Applications for the program will open soon. You can find more information here. Thank you so much to the crew of NOAA Ship Bell M. Shimada, the EXPRESS Scientists, and the NOAA Teacher at Sea program for this opportunity. What an incredible experience!

July 25 – August 9, 2023

Mission: Shark/Snapper Long Line Survey

Geographic Area of Cruise: Gulf of Mexico/Atlantic Ocean

Date: Jul 28, 2023

Longitude: 79°59.970’W

Temperature: 30.5° Celcius

Wind Speed: 7 knots

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.

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.

Safety Onboard

Obviously, safety is of the utmost importance out here at sea. Respect. When working on deck, crew must wear life vests, hard hats, sometimes safety belts, and closed-toe shoes. I don’t know how these people wear closed-toe shoes all day long. I hate it. My piggies are suffocating.

The plan of the day for Friday (6/10) included safety drills at noon. Noon rolls around and I am not really sure what to do. No surprise there. Confirm with Paul what to do and where to be. Oh, okay. Amanda, Caroline, and I go grab our safety getup and start to head to our assigned life raft muster stations (where we gather). On the way down, Commanding Officer LCDR Jeffery Pereira, passes by. “Wow, you ladies are ready.” …… something tells me it’s not quite time. We promptly return to our stateroom. I casually go check our muster stations. Yep, there’s no one. Turns out drills commence with a signal. I’m on to you CO, you just getting a kick out of us roaming around like fools with our safety gear. It’s okay, I have accepted my role onboard.

We run through fire and abandon ship drills. At sea, everyone aboard ship, be they crew, scientist, or passenger, is a member of the fire department. When the alarm sounds, everyone jumps to respond. My response, go to the back deck and wait. Meanwhile, the crew is hard at work donning firefighting PPE and preparing fire stations. Great work, team!

Then we move on to the abandon ship drill. Abandoning ship in the open sea is an action of last resort. Only when there is no reasonable chance of saving the ship will the order ever be given to abandon it. When signaled, everyone reports to their assigned life raft muster station with their protective survival gear. We throw on our survival suits, or immersion suits, and in the actual event, would launch the life rafts. This immersion suit is intended to protect your body while out in the open ocean. Now, I know safety is serious business, but these suits are ridiculous looking. We somehow make them look good. I’ve said it before; I’ll say it again – safety is sexy.

Science and Technology Log

We spent our first day at a reef known as Claypile Bank, approximately 80 miles offshore. The second day we headed to East Flower Garden Banks, 125 miles offshore. Flower Garden Banks National Marine Sanctuary was expanded from 56 mi² to 160 mi² to protect critical habitat in the Gulf of Mexico in 2021 and is now made up of 17 different reefs and banks. Cameras were dropped at around 48 meters (or 157 ft) the first go around and 116 meters (380 ft) the second. Since the start, we have sampled Rankin Bank, Bright Bank, and started on Geyer Bank, with a total of 62 cameras deployed. That’s a lot of cruisin’ and droppin’.

Camera Operations

Let’s talk about these cameras. Deploying and retrieving cameras occurs ALL DAY LONG. Man, the days are long. Here is a quick summary of the work…

Dropping the camera

There are two camera arrays, one 48” tall and the other 36” tall. These things are beastly. Each Spherical/Satellite camera array has six video cameras and a satellite camera, battery, CTD, tensiomet… tramsmiss… transmit…. What it is Ken? … TRANSMISSOMETER (measures visibility/turbidity), sonar transmitter, trawl net ball, and bait bag. The first camera goes out at 7 AM and the last by 6:15 PM. Predetermined sampling sites are selected along the U.S. continental shelf using random stratified selection (dividing the area into subgroups).

When at the site, cameras are lifted by the A-frame, dropped with the yank of a chain, and boom, they sink to the bottom. They sit on the seafloor and soak (record footage) for 30 minutes. First camera goes in, we head to the next site, second camera goes in, we retrieve the first, we retrieve the second, and repeat.

Though the deployment itself only takes like two minutes, there is a lot of coordination involved. It’s amazing how the Bridge (NOAA Corps), Deck, and Lab crews work together to effectively deploy and retrieve the cameras. The communication is nonstop. Field Party Chief (FPC if you know him), Paul Felts, is the brains of this operation. Paul keeps scientific operations running smoothly, providing coordinates to selected sites, monitoring conditions, keeping time, processing data, and I am sure so much more. This guy doesn’t stop. The Bridge are they eyes and ears – they are on watch, navigating to sites, and maneuvering and position the ship all while working against the elements. You guys deserve more credit than that, I know. The Deck are the hands (this is a terrible analogy, but I am committed at this point) – they are operating the deck equipment, raising and lowering cameras, and working the lines and buoys. I, Teacher at Sea Jordan Findley, am the appendix. I have potential, but am mostly useless, and can be a real nuisance from time to time.

Personal Log

We are almost one week in and I am still just as excited as day one. Have I encountered challenges, yes, but being out here in the middle of the Gulf is something special. I am greeted every day with a beautiful sunrise and evening sunset. It is spectacular. The water is so beautiful. One of the things I really hadn’t considered to impact my experience at sea is how amazing the people would be. You all inspire me. Every single person on this ship has been so kind and accommodating, allowing me to participate and taking the time to teach me, despite how long they’ve been out at sea or how long their day has been. It’s like one big (mostly) happy family out here. They have me cracking up all the time. Now, they could just be on their best behavior for the ol’ teach (that’s me), but I am convinced they’re just good people. I mean, I even like most of them before my morning coffee. That’s something right there.

I think I am getting my groove. On a typical day on the ship, we wake up at 6 AM (oof), breakfast, then to the lab. I like to take a minute on the back deck to drink my coffee and look out over the water. First deployment (CTD and camera) is at 7 AM. They do some science, and then continue to deploy and retrieve cameras about every 10-30 minutes until sunset. I pop in and out of the lab all day to observe, but try to keep myself busy. When I am not “helping out,” you will find me in my office. Some call it the mess. I don’t mind. It’s also conveniently where all the food is prepared and served, and where the coffee and snacks are located.

We all refuel on coffee during lunch. Shout out to Paul for making that coffee a real punch in the face. Fishing occurs in the afternoon, almost daily. More to come on this, but man it is fun. The rest of the day is a waiting game (at least for me). Living on a ship is weird; there is only so much you can do. Honestly, the first couple of days, I had some concern I might die of boredom, but as things progressed, I got more involved in every aspect of the operation – even driving this beast! Also, been trying to sneak in a workout. Don’t forget to hydrate. That breaks up the day a bit. Dinner rolls around at 5 PM. All I do is eat. I have been eating like a grown man. The crew starts to wrap things up, reset for the next day, and then transition to mapping operations. The day isn’t complete without watching the sunset. Then we just hunker in until bedtime. The ship “rock-a-bye babies” everyone to sleep.

Generally speaking, I have improved immensely on my ability to open doors – solid 8/10. Those heavy brown doors though, they still kick me in the butt on my way through. I am learning my way around the ship for the most part. Mmmm, kind of. There is a door like every five feet. What I have not improved on is my ability to walk. I am walking all sorts of ways but straight. Everyone stands clear when I walk by. They say you’ll get your sea legs, but I am not sure I am convinced.

Did You Know?

A continental shelf is the edge of a continent that lies under the ocean. Though underwater, continental shelves are still considered part of the continent. The boundary of a continent is not the coastline, but the edge of the shelf. The shelf extends to a drop-off point called the shelf break. From the break, the shelf descends deep to the ocean floor. Depths of the shelf where we sample range from 45-165 meters, mostly because it gets to be too dark much past that. The depth of the Gulf of Mexico can be more than 5,000 meters deep! Sorry friends, I am done converting units – we’re doing science out here. Just know that it’s deep.
