Science and Technology Log

The science, travel, and community that make life aboard NOAA Ship Thomas Jefferson possible rely on the team hard at work in the galley. The cooks in the steward department serve a hot breakfast every morning at 7:00 a.m., offering eggs to order, pancakes or waffles, bacon, turkey bacon, sausage, and grits or oatmeal, along with fruit and a variety of sauces.

At 11:00 a.m., they serve a wide array of lunch options. Tuesdays are usually Taco Tuesday—a crew favorite—though the menu varies based on what Chief Steward Danni Cuff creates. She posts the weekly menu in advance so everyone knows what to expect. This also allows crew members to request a plate to be saved if they are working on the small boats or on shift outside galley hours.

Dinner is served at 4:30 p.m. Last week featured a surf-and-turf dinner with crab legs and steak. It was my first time trying crab legs, and I have to say, I prefer them over lobster.

For dessert tonight, I joined the Chief Steward in the galley to help make and decorate a white cake. Before we frosted it, she gave me some pointers on piping practice. Since she couldn’t find the exact piping tip she wanted, she also showed me how to cut a pastry bag to create one from scratch.

The Chief Steward’s role extends far beyond baking. She manages her department and ensures her team receives professional development while in port; one of her crew members will soon attend training at The Culinary Institute of America. 

In addition to staff management, Danni oversees inventory and supply ordering for each leg of the voyage. She is currently developing an automated inventory system designed to generate supply orders and vendor lists based on planned menus and upcoming crew counts.

Personal Log

Before embarking on this leg aboard NOAA Ship Thomas Jefferson, one of my biggest worries was the menu. I don’t typically care for seafood and have actively avoided it in the past, so I even reached out to a past Teacher at Sea participant to ask about the food. It turned out to be a total non-issue for three reasons: 1. Danni consistently provides multiple lunch and dinner choices (as seen on the weekly menu), alongside a fully stocked salad bar and sandwich station; 2. She takes great care with dietary restrictions and allergies. With so many options available, personal preferences are naturally accommodated as well; and 3. I’ve actually found myself reaching for seafood intentionally. Danni has prepared my favorite—catfish—both grilled and fried, and served dishes I had never tried before, like pollock and crab legs. Looking at menus from previous months, I noticed even more local, sustainably sourced species I would love to try.

Danni puts incredible thought, care, and effort into her work, and everyone aboard NOAA Ship Thomas Jefferson deeply appreciates her dedication—and her delicious meals.

Did You Know?

A waterspout is a spinning, funnel-shaped column of air and water mist that forms over a large body of water. At the end of the day that I spent with Danni, we saw a waterspout off of the side of the ship.

Science and Technology Log

I spent the overnight shift with Hydrographic senior survey technician Emily Madish tonight. Her shift starts at 3:30 p.m. and goes until 3:30 a.m. She worked with two other crew members in the survey room: Operations Officer Jessie Spruill and Hydrographic Survey Tech Hannah Hernandez. There were more members of the crew on the deck navigating the ship through the dark waters.

I took the opportunity of the quiet evening and having fewer people around to have Emily walk me through the process for collecting data on NOAA Ship Thomas Jefferson and to explain how the scientific equipment on the ship works to collect depth data. 

Hydrographic surveys make use of a variety of fundamental physics concepts. One of them is how sound travels. Sound travels at a constant speed through a medium (a material like water or air) unless the properties of the medium change. In lake or ocean water, properties that could change the speed are the salinity, temperature, and depth. Thomas Jefferson accounts for these possible changes by collecting that information using the Moving Vessel Profiler (MVP) and collecting that data approximately every hour so that the data collected by the ship can use the most accurate information to create the depth profiles. 

three graphs in a row with different x-axes: sound speed (meters per second), temperature (degrees Celsius), and salinity (practical salinity units), all versus the same y axis of depth in meters
This is the graph the MVP software displays, collects, and transfers to other software that works in conjunction with the MVP. This is one of the casts taken from Thomas Jefferson

Once the speed of sound in the area has been collected, the time it takes for the sound to go to the bottom of the seafloor (or in this case lakebed) is collected. From there, the depth of the seafloor can be calculated using the equation:

Velocity equals depth over time

To solve for depth, it becomes

depth equals velocity times time

However, the time included at this point includes both the time leaving the ship and going to the seafloor and back again, which can be visualized like this: 

To account for the reflection, the time that is collected is cut in half and the new equation becomes:

depth equals velocity times time divided by 2

(Note: hydrographers use different letters to represent these variables, but I’m keeping everything in notation my high school students are or will be familiar with. They mean the same thing.)

Now, this seems relatively straight forward so far. However, what is really cool is that the ship is not taking just one sounding (depth measurement). Instead, the ship is sending out SONAR in a fan shape using a multibeam or side scan, which can be visualized as follows: 

illustration of a swath of sound waves emanating from beneath a ship and sweeping over the seafloor to different depths
Typical geometry of bottom tracking multibeam sonar. 
Image from Mayer, Larry & Li, Yanchao & Melvin, Gary. (2002). 3D visualization for pelagic fisheries research and assessment. ICES Journal of Marine Science – ICES Journal of Marine Science. 59. 216-225. (ResearchGate)

This allows not only the various depths of the sea floor to be collected, but because many (MANY) soundings are taken at once, the soundings can also translate into images and an image of the seafloor can be created. In addition to an image of the seafloor, it is also possible to find out if there are any hazards to shipping or features on the seafloor. For example, in Lake Erie on the last leg of the mission a lot of shipwrecks were seen, and while there haven’t been any shipwrecks found on my leg as far I know, some features of the lakebed, like glacial scarring may have been seen, along with a lot of rocks. A lot of rocks. 

It is also possible to see schools of fish in the water column or capture an image of a whale with the multibeam or sidescan.

To get to the point of creating an image and having the image accurately represent the location of where the data was taken to create a meaningful map, while also correcting the data for errors and the motion of the ship requires many steps. 

First, the Seafloor Information System collects real time depth data being collected by the multibeam sonar, while HYSWEEP communicates with the bridge. Those in survey use HYPACK to make planned survey lines, and those on the bridge use HYSWEEP and follow those lines. The bridge and the survey team are in constant communication while this process is ongoing.

Thomas Jefferson travels back and forth like someone mowing their yard with long back and forth lines that overlap by about 20% to make sure that no areas are missed.

This is the second swath the ship makes as it goes past the same location as the image above with the glacial scarring

The ship also collects what is called crosslines, which must be collected for every 4% or 8% of the lines collected that are parallel to each other, depending on the spacing between the lines, to make sure that the data remains reliable. It is possible the parallel lines could be offset from each other and the crosslines ensure that they are not. 

photo of a computer screen displaying collected sonar readings; many of the lines are parallel sweeps, but there are also diagonal lines that cross over these and help true the data
An entire sheet that shows where data was collected including crosslines (the diagonal lines) and the lines parallel to each other

Once the data is collected, the data from GNSS including GPS and information from other satellites is collated with the ship’s depth data. This involves a lot of additional software that ensures the accuracy and fidelity of the information being collected. 

After everything has been processed, it is sent to NOAA for further integration into the maps that allow ships navigating the waters carrying people and goods across the Great Lakes stay safe.

Personal Log

It’s fascinating to notice how life aboard the ship mirrors research experiences I’ve had elsewhere. During my undergraduate and graduate work, I spent night shifts at Brookhaven National Laboratory and Argonne National Laboratory running experiments at the synchrotrons. The late hours aboard the ship feel remarkably similar.

Night shifts have a distinct stillness. Instead of the busy daytime chatter and people moving about, the ship settles into a steady rhythm defined by the deep hum of instrumentation and running equipment. Monitors glow with data software, and as the end of the shift approaches, fatigue sets in—making it just a little easier to make a minor mistake (though usually the mistakes are fixable). Sometimes it even feels like the software itself gets tired of being up that late and starts acting up. But through it all, really cool data is collected despite anything else that happens.

Did You Know?

NOAA Ship Thomas Jefferson is sent out after natural disasters like hurricanes, to help ships enter and exit ports. The ship helps make certain that there are not any dangers to ships from the disaster, so that rescue, shipping, and reconstruction after the disaster can proceed.

Science and Technology Log

A NOAA research vessel is a 24-hour operation. The crew works 12-hour shifts that can start at any part of the day or night and in the rain or shine, pitch black or full daylight.

My day began in the quiet dark at 5:00 a.m. with Ensigns Connor Harrell and Julian Santos as they prepped one of the ship’s small survey boats. Before heading out on the water, thoroughness is everything. They meticulously inspected the engine compartment, checked the water and oil lines, verified the batteries, and—equally crucial for a long shift—packed their sandwich ingredients for the day.

By 6:00 a.m., the entire crew gathered for the daily safety meeting to review small boat operations, including resolving past mechanical issues and flagging things to watch. We discussed both small boats on Thomas Jefferson: one had just received a new alternator, while the other developed a persistent clicking sound. The cause? It requires a specialized lubricant that isn’t currently stocked on the Thomas Jefferson. A temporary alternative lubricant is keeping things safe and operational in the meantime, even if the click remains for now.

By 6:20 a.m., it was time to launch. Watching the coordination required to launch both small boats was incredible—it took less than five minutes per boat. I watched my roommate, Hydrographic Survey Tech Haley Kenyon, balance on the moving small boat, calmly releasing heavy lines, relying entirely on her upper body strength and footwork before stepping back inside.

These small boats serve as essential advance scouts for the Thomas Jefferson, especially when surveying specialized areas like designated dumping grounds. Using side-scan sonar, they map the seabed and detect potential hazards in shallow or tricky waters, ensuring our main vessel can later navigate safely to conduct high-resolution multibeam survey scans without risking the ship’s hull. Deploying the small boats also speeds up data collection significantly—with Thomas Jefferson and two small boats working simultaneously, we can map vast stretches of the lakebed in a fraction of the time.

Of course, science at sea always comes with unexpected variables. Boat 2903—the one with the brand-new alternator—ran into electrical trouble mid-morning and had to be recovered early. While Boat 2904 pressed on with its mission, the crew was understandably frustrated. But on a research ship, equipment problems are simply part of the job, and it was necessary to bring the boat in for further inspection.

Meanwhile, aboard Thomas Jefferson, we were running our own multibeam scans. The multibeam and sidescan systems integrate positional data from a variety of Global Navigation Satellite Systems (GNSS) including GPS, European Galileo satellites, and other available orbital networks with depth soundings.

To turn sound waves into precise depth measurements, however, you need to know the speed of sound in water, which changes constantly based on temperature and salinity. To capture these variables, a Moving Vessel Profiler (MVP) is deployed. Towed behind the ship, the MVP measures salinity and temperature profiles through the water column. The survey techs aboard NOAA ship Thomas Jefferson launch it roughly every hour, or whenever we transit to a new area, allowing us to continuously calibrate our sonar equations against local water conditions.

At 4:00 p.m., Boat 2904 returned to the ship. We wrapped up the afternoon with our daily debrief—a chance for both the small-boat teams and the shipboard crew to compare notes, troubleshoot the day’s electrical snags, and refine our approach for tomorrow before heading off to dinner.

Personal Log

Living quarters on a working ship must make use of every usable square inch. I share a room with Haley Kenyon, one of our fantastic survey technicians (and one of the people who went out on the small boat from the morning’s launch video).

Our room is surprisingly spacious with plenty of storage. Haley is a permanent staffer, so she’s aboard Thomas Jefferson long term, while I’m settling in for my two-week adventure. We each have space in the dresser and closets, and I have the bottom bunk. While the porthole offers a fantastic view of the lake, my lower berth keeps the early morning light out of my eyes.

Our room connects to the adjacent stateroom via a shared Jack-and-Jill bathroom with a toilet and shower. It’s compact, but totally functional. Both connecting doors lock securely from the inside—though there’s always a slight paranoia about accidentally locking yourself out. Conveniently, our sink and mirror are located right inside our bathroom in our bedroom, making it super easy to brush teeth and wash up even if the bathroom is occupied.

Did You Know?

Dessert is a mandatory shipboard requirement.

On NOAA Ship Thomas Jefferson, official protocol dictates that the crew must be served a dessert at both lunch and dinner. We are extraordinarily lucky because our Chief Steward, Danni Cuff, is a pastry chef trained at the Culinary Institute of America.

Needless to say, the food aboard is great. So far, my scientific duties have been complimented by an impressive rotation of scratch-made cakes, pies, and warm cookies.

Science and Technology Log

Today was jam-packed with preparation, community, and reflection. I was struck not only by how meticulously everyone prepares for emergencies, but also by the crew’s thoughtful debriefs. They continuously strive for operational perfection, yet never at the expense of appreciating a job well done.

We began the morning with shipboard safety briefings. At sea, addressing a fire quickly is paramount. Everyone has a designated duty and muster station. On land, the standard advice for a building fire is to evacuate immediately—even if it’s small. However, as the Executive Officer (XO) and crew emphasized, if you spot a small fire aboard ship, the best immediate action is to grab an extinguisher and put it out. The reason for this stark difference is simple: on open water, help is miles away. An uncontrolled fire endangers the entire vessel, forcing an abandon-ship scenario that carries far greater risk than tackling a localized flame right away.

There were two new members of the crew besides me. They were assigned to firefighter roles and we went through the process of getting them gear and setting it up so that they could just hop into it if they needed to use it. 

two men stand in an interior room of the ship wearing khaki firefighting jackets and pants and protection for their hands. they smile for a photo. hard hats and life jackets are stored on the wall behind them.

Should the call to abandon ship ever be given, comprehensive protocols are already in place. Everyone gathers their immersion suits and proceeds to the lifeboats. Each lifeboat holds up to 20 people. With roughly 30 personnel currently aboard the Thomas Jefferson and several lifeboats available, there is more than enough capacity for everyone.

From safety drills, we transitioned to the Leg Operations Brief, led by Operations Officer Mark Meadows. This meeting serves a dual purpose: preparing for the upcoming leg while reflecting on the previous one. Because personnel rotate frequently—some staying for multiple legs, others returning home or arriving from across the country—a structured presentation ensures a seamless transition. The team openly analyzes both the strengths and challenges of the prior leg to set up the incoming crew for success.

Next was a technical discussion on Pulse Per Second (PPS), a concept directly applicable to the data-collection software used on board. Operations Officer Meadows provided a thorough explanation, highlighting why understanding the mechanics behind our equipment (and its software) is crucial for real-time operational adjustments.

The software generates a pulse display similar to the diagram below:

photo of a visual output display from an older instrument. it features a graph of volts versus time, with a yellow line pulsing vertically up, over, and then back down.
Example of a 1 pulse per second signal generated by a GPS receiver. Photo from Codrey Electronics.

The time from the leading edge of one pulse to the leading edge of the next is exactly 1 second. Meanwhile, the duration between the leading edge and the trailing edge of a single pulse is approximately 1 millisecond (ms). This subtle nuance means it is remarkably easy for data collection to end up off by a millisecond. In many contexts, that tiny margin is negligible; in high-precision hydrography, it matters. Recognizing how the software handles these signals allows the team to correct data post-collection if needed. It reminded me of a favorite lesson from my own high school physics teacher: Always understand how your equipment works so you know how to troubleshoot it when it doesn’t.

After the briefings wrapped up, it was time to get underway! This was the moment my physics-teacher heart sang. It’s rare to see a fundamental physics concept demonstrated so dynamically in real life.

The deck crew expertly maneuvered the ship away from the dock, accounting for wind force, current, and the thrust vectors of the ship’s engines. It was a beautiful, real-world ballet of vector addition—one that my students would be relieved they didn’t have to calculate on paper! The crew handled the separation from the dock and navigation around the pier with effortless precision.

Once we reached open water, the crew gathered for what the XO fondly called “Story Time”—a post-maneuver debrief. Once again, they analyzed what went smoothly and what could be refined. They praised the steady speed and smooth handling, while constructively noting that higher communication volume over the radio would make it easier for everyone to follow along. Both praise and critique were taken to heart. Because the Thomas Jefferson will be navigating this same harbor all season, the pursuit of perfection is an ongoing goal—but everyone acknowledged that the crew’s skill today was exceptional.

Personal Log

Trying on the immersion suit was pretty hilarious. I unrolled it in my stateroom and then I had to read the directions. Are you supposed to keep your shoes on? Yes, and luckily, it says so on the instructions on the outside of the packaging. I was able to get into it ok, and then I kind of flopped upstairs so I could get help with getting a picture. I also realized that in a real emergency, I will need some help zipping it up because the zipper is very hard to slide. I’ll have to practice that some more. The worst part though, was taking it off and then rolling it up and putting it back into its bag. I’m not going to lie, that part was a little rough.

Did You Know?

The Great Lakes are technically considered non-tidal.

Ocean tides (true tides) are generated by the gravitational pull of the moon and sun. While the Great Lakes do experience a spring tide during a new or full moon, the water level changes by only about 2 inches (5 cm)—compared to 5 to 7.5 feet in places like the Long Island Sound. Because these lake tides are so minor, they are masked by greater local weather forces and categorized as non-tidal.

However, the Great Lakes experience short-term water level fluctuations that closely mimic ocean tides. These are called seiches (pronounced sayshes)—standing waves that oscillate back and forth within an enclosed or semi-enclosed body of water.

Unlike tides driven by gravity, seiches are driven by strong winds and rapid changes in atmospheric pressure that literally push water from one end of the lake to the other. Lake Erie is famous for dramatic seiches, but all the Great Lakes experience them. In fact, in 1954, the extreme winds of Hurricane Hazel piled up so much water near Toronto that it triggered a massive seiche on the opposite shore of Lake Ontario!

Real-World Career Pathways at Sea

Before stepping aboard NOAA Ship Thomas Jefferson, I assumed most of the crew would be scientists. While hydrography is certainly at the heart of the mission, I learned that it takes professionals from many different career fields to keep the ship operating safely and efficiently. In fact, many of the jobs on board connect directly to the career pathways offered where I teach, Pickaway-Ross Career & Technology Center.

The survey technicians are responsible for collecting and processing hydrographic data using multibeam sonar, side-scan sonar, GPS, and specialized computer software. Their work combines engineering technology, robotics, and cyber security & networking.

The deck department operates cranes and davits, launches and recovers the survey boats, performs maintenance, handles lines during docking, and ensures the safe operation of the vessel. These careers require technical skills, teamwork, problem-solving, and attention to safety which are qualities developed through career and technical education programs. Especially since we train our students in Lean Six Sigma.

Behind the scenes, the engineering department keeps the ship running 24 hours a day. Engineers maintain the propulsion systems, generators, pumps, electrical systems, and countless pieces of equipment that allow the Thomas Jefferson to complete its mission. Students pursuing careers in diesel technology, industrial maintenance, electrical trades, or advanced manufacturing would recognize many of the same hands-on skills used every day aboard ship.

The bridge is staffed by NOAA Corps officers, who are responsible for safely navigating the ship, supervising survey operations, managing personnel, and making operational decisions. Their careers combine leadership with navigation, meteorology, technology, project management and safety. These officers work very similarly to the students in the Public Safety course at PRCTC.

Even the steward department plays a vital role. Preparing three meals a day for a crew working long hours requires planning, organization, food safety knowledge, inventory management, and culinary skills. The galley keeps morale high and ensures everyone has the energy needed to perform demanding work much like our commercial foods program.

The Thomas Jefferson also relies on electronics, communications, information technology, logistics, administration, and medical support. Every member of the crew contributes specialized skills that allow the ship to operate as a single, coordinated team.

One of the biggest takeaways from this experience is that there isn’t just one pathway to working aboard a ship like the Thomas Jefferson. Whether your interests are welding, diesel technology, engineering, information technology, culinary arts, electronics, leadership, or science, there is a place where those skills can make a difference.

As a teacher at Pickaway-Ross CTC, this experience has given me real-world examples to bring back to my classroom. Now I can point to an entire ship where technical skills, problem-solving, teamwork, and communication are used every single day. Career and technical education doesn’t just prepare students for jobs, it also prepares them for opportunities they may have never imagined, including serving aboard a NOAA hydrographic survey vessel.

Clearing the Way

While the NOAA Ship Thomas Jefferson is best known for charting U.S. waters, the ship can also play a critical role in responding to natural disasters.

In 2017, after Hurricane Maria devastated Puerto Rico and the U.S. Virgin Islands, the Thomas Jefferson was deployed to help restore safe navigation to the region. Using its multibeam sonar and side-scan sonar systems, the crew surveyed ports and waterways to identify underwater hazards and ensure safe passage for the U.S. Coast Guard, relief vessels, and other emergency responders. Because so many essential supplies reach the islands through these ports, reopening them quickly was vital to the recovery effort.

Over the course of just three weeks, the Thomas Jefferson surveyed 13 areas, including more than 18 ports, helping authorities safely resume maritime traffic.

One of the ship’s greatest strengths is its ability to operate independently. With a crew of 38, the Thomas Jefferson can remain at sea for several weeks without relying on outside support, making it an ideal platform for extended emergency response missions. Its two survey launches, 2903 and 2904, further enhance its capabilities by allowing crews to survey shallow waters and areas where storm debris may have accumulated.

Learning about the Thomas Jefferson‘s role after Hurricane Maria gave me a broader perspective on hydrography. Before this experience, I mainly associated nautical charting with supporting everyday navigation. Seeing how these same surveying skills and technologies can be used to assess storm damage, clear ports, and help restore critical shipping routes showed me just how important this work is. It is another example of how the crew’s expertise extends far beyond routine charting operations.

Personal Log

Unfortunately, I am on my way home. However, I want to share a few last memories from this experience.

The Crew’s Greatest Challenge

I had started to think the crew aboard the Thomas Jefferson was almost flawless, then game night happened.

Communication on the bridge during unfavorable conditions is exceptional. Navigating video games? Not so much.

The Commanding Officer remained calm, cool, and collected through two weeks of transiting the Welland Canal, changing weather, and demanding survey operations. Yet during game night, I caught a glimpse of what looked like a silent question in the CO’s eyes: “Is this really my crew?” as everyone demonstrated their less-than-stellar teamwork in a video game. I also learned that it is, in fact, possible to earn negative points.

The evening was filled with unforgettable comments like, “I have steak on the starboard quarter!” followed by, “Fish pasta, aye!” and “Who keeps putting the fire extinguisher on the stove?” Somehow, those made perfect sense in the middle of the chaos. And no game night would be complete without a few “passionate” debates over the official rules of Scrabble.

As entertaining as the games were, my favorite part was seeing this side of the crew. After watching them work with such precision and professionalism every day, it was refreshing to see the Commanding Officer and Executive Officer relax alongside everyone else. For a few hours, ranks took a back seat to friendly competition, laughter, and good-natured teasing. It was a wonderful reminder that the strong teamwork I had witnessed throughout the mission is built not only through hard work, but also through shared moments like these.

Sharing the Mission

An exciting part of my journey home was getting the chance to share my experience aboard the Thomas Jefferson with people I met along the way. My Uber driver and the hotel front desk attendant were both curious about why I had been on a NOAA ship, which gave me the opportunity to explain the mission of the Thomas Jefferson and the important work the crew does to create accurate nautical charts and ensure safe navigation. They both had said they had lived here all their lives and never saw a boat like that in the port or knew that the lake was not surveyed. After spending time with the crew, I found myself proudly talking about their work and the dedication it takes to accomplish such an important mission.

Mission Complete

I want to extend my sincere thanks to Commanding Officer Kidd and Executive Officer Duffy for welcoming me aboard and giving me the opportunity to be part of this incredible experience.

I also want to thank the entire crew for making me feel at home from day one. Everyone was so welcoming, patient, and willing to answer my endless questions. A special thank you goes to the survey technicians, who took the time to explain everything to me slowly and more than once when needed. Their patience and enthusiasm for their work made it easy to appreciate the science and technology behind every survey.

I also want to thank my roommate, Junior Officer Bridget Ruiz, for making life aboard so enjoyable. Thank you for your friendship, the great conversations, and for making me feel at home while we were at sea. Sharing this adventure with you made the experience even more memorable.

I feel incredibly fortunate to have been assigned to NOAA Ship Thomas Jefferson. I have a much deeper appreciation for the important work this crew does. More importantly, I am returning home excited to share what I have learned with my students. I hope that through these stories, they will discover careers they may have never considered and see that science can lead to adventures far beyond the classroom.

Fair winds and following seas, Thomas Jefferson. Thank you for an unforgettable journey.
