Geographic Area of Cruise: Northwest Atlantic Ocean
Date: August 15, 2025
Weather Data from Bridge:
First, Someone named Suzy asked if I am hopeful for the future of our oceans after seeing all the work that is done on my NOAA cruise. I am hopeful every day I get to go to school and see the brilliant young minds that are learning and developing so that they may work to solve our world’s problems. (Read more here). The dedicated people I’ve met through NOAA and on NOAA Ship Pisces remind me that we are using science in productive ways, like taking care of our oceans! Are you learning and doing your part? Thank you for reading and asking questions!

Second, the answers to the math problem from the previous BLOG: If we sorted through 1/8 of our Bongo net sample, and identified 20 krill, then we would estimate there to be 160 krill in the total sample. For part 2, the abundance is estimated as the number of krill expected per cubic meter. If the nets filtered through 5 cubic meters of water, we would expect to find 32 krill per cubic meter in this part of the ocean. (Alert, we’ll soon be calculating energy density in Chemistry!)
Observers Observing!
Science at Sea: Purpose! On purpose! With purpose!
It is hard to believe that my two weeks onboard NOAA Ship Pisces have come to an end. In many ways, it seems like I have just started. But when I reflect on all that I have learned about the science being done at sea, I realize I have been here long enough for some important things to sink in! I’d like to share some of these things with you.
Many of the Scientists I spoke with said that math wasn’t their thing. You don’t have to like math to do science, you do have to do some math, understand some math, check behind the computers on some math. There is a difference. We don’t live in a binomial world. You can’t say not liking math is a reason to not do math.
Science is a process. It is not a list of boxes to check or things to do. Science is a way of looking at the world. Observe, analyze, reflect, repeat.
Science can be used for good. NOAA Scientists are making our lives better.
We need more scientists. Are you ready? I’m ready to start a new school year sharing the insights I’ve learned as a NOAA Teacher at Sea!
Gear is ready for next time!
You do the Math: I’ve worked 12-hour shifts, 3pm-3am each day of the Summer2025 EcoMon meeting Scientists, doing science, seeing Science in action, and developing ways to connect my students with relative, real-world experiences. How many hours of professional development credit should I receive? OR Since a work day is considered to be 8-hours, how many days of “comp time” should I earn? (Teachers in some schools can earn “compensatory time” for work done outside of the school day, to be used on teacher workdays, not on regular days with students.) Feel free to post a kind reply in the comments.
Yes, that’s a sea horse!
Interesting Things: As a NOAA Teacher at Sea participant, I have had the privilege to work with an awesome Summer EcoMon 2025 crew. I have basked in the joy of focusing on science and ways to bring back some insights to my classroom in North Carolina. Some observations have come more organically than others. For example, on the Pisces, the mission is clear. Every department is working towards the goal of collecting our scientific data, but not in the same way. At school, our departments are also working, but sometimes our goals are in conflict… Increase test scores? Winning football season? Resume booster? Full stomachs? Social conduit? College acceptance? Understand the world? Develop skills? Create citizens? Workforce development? Avoid gun violence? Learn content?
The Wardroom
NOAA Corps is responsible for operations, safety, and project completion (possibly like school administration) but they must rotate off the ship after 2 years and they don’t make decisions unilaterally. Their well-honed leadership comes in understanding the institutional knowledge of each department.
I wonder what would happen if our school systems invested in clear missions and departmental leadership. I would settle for “just” focusing on science! 😊

Teacher at Sea/ Career Spotlight:
As part of my Teacher at Sea work, I’ve created a game to help my students see many of the people and careers on the NOAA EcoMon cruises. In addition to the Science, NOAA Corps, Deck, and Engineering departments I’ve been able to highlight in my blog posts, the Stewards, Survey, and Electronic Technician departments are also mission critical. Come to West Johnston to play my Career Exploration game.
I’ve also found ways to integrate real world skills and relevant examples into the content I teach. Next year specifically, we will be honing my “Death at Sea” Forensics Lesson and “Ocean Calorimetry” Chemistry lesson. Finally, I will be leading a session called “Come Sail with NOAA” at the NC Science Teacher’s Association PD conference in November. If you would like to learn more about applying to be a NOAA Teacher at Sea, or a Science Teacher in North Carolina, please come check us out. (read more here: NCSTA)
After our last data collection stop, we checked out the last sunset!
Personal Log: I am thankful for my community – those who have and continue to nurture, teach, and inspire me to observe, learn, enjoy, and be curious! This is going to be the best school year ever!!

First, Ferdinand asked about Sea Surface Temperature (SST) data the ship is collecting and how to access it. Storm Events, like the Hurricane Dexter and Tropical Storm Erin draw energy from warm ocean waters, which act as their primary fuel source. Warmer waters lead to increased evaporation and provide more latent heat to the storm, allowing it to strengthen. The National Weather Service (NWS) is a part of the National Oceanic and Atmospheric Administration (NOAA) and uses SST data in making forecasts. The data is available publicly here. Thank you for reading and asking good questions!

Second, an answer to the math problem on the last BLOG: If each of the engines’ cylinders has a displacement of 51 liters, and the engine has 12 cylinders, so the total displacement of the engine is 612 liters. The displacement from a car engine could fit into the Pisces 204 times.

Science at Sea
How do we know that satellite information is valid? The satellites must be calibrated, just like the sensors in all other electronic devices.
One ongoing project taking place on our NOAA Summer EcoMon cruise is a calibration validation of a NASA PACE satellite measuring plankton. (See more here.) Victoria and Rowan are Biological Oceanographers, studying how light interacts with the ocean. Once a day, when the PACE satellite crosses over our location, they throw out the radiometer, pull it to the surface from different depths, and ensure it is collecting radiation or light data as it sinks to about 1% light transmission.
Victoria and Rowan also test the water with radiometer casts, once per day during satellite overpass. If we are doing a CTD stop, they will use water from the Rosette, but if we aren’t doing a CTD stop they can use water from the flowthrough system in the chem lab sink. This is a special plumbing network that allows seawater from below the ship to be retrieved in the lab spaces. These tests must happen during daylight hours.
The water is filtered out for particulate matter (plankton and other stuff) and colored dissolved organic matter (CDOM). These will eventually be used to characterize coloration through a spectrophotometer, although some of it will go directly to NASA. That’s right. They measure the wavelength of water, specifically how the light and color change throughout the water column.
The data are analyzed, triangulated, and compared with data being collected at other places. (Read about another validation team here.) Understanding light saturation might someday help fisheries measure water health in ways that will save money. If areas don’t have plankton, the bottom level of the food chain, then they won’t have higher levels either and fisheries should look elsewhere to fish.

Another member of the science crew is collecting dissolved oxygen and dissolved inorganic carbon data as we make our planned stops. It seems like everything is tied to Chemistry in some way!

You do the Math: If we sorted through 1/8 of our last sample from the Bongo nets, and identified 20 krill, how many krill would you estimate to be in the total sample. Then determine abundance if the nets filtered through 5 cubic meters of water. In other words, how many krill would you estimate we would find per cubic meter in this part of the ocean. Check in the next blog post for both answers.
Career Spotlight: James Walker, Chief Boatswain.
Chief Boatswain James Walker
James Walker serves as Chief Boatswain on NOAA Ship Pisces where he manages a 7-person department. He holds a bachelor’s degree in Human Resources from Park University. Having retired from serving 20-years in the Navy and serving as the Upward Bound Activities Coordinator for the University of Tennessee, James joined NOAA 18 years ago.
He is responsible for running the gear for our science experiments – cranes, hydro wrenches, A-frames, net grills, bongo nets, and CTD rosettes – as well as watch, lookout, and security. Without James and his crew, the experiments could not happen.
He loves playing all sports, especially bowling and baseball. His favorite tool is his computer because it keeps him informed of what is happening on the ship and in the world, but mainly because it keeps him in touch with his family. With his wife and nine children back home in Tennessee (ok, one child escaped to Mississippi), staying in touch is an important task!
Do you see James Walker’s name on the plaque?
Interesting Things: James Walker is also a NOAA Ship Pisces plank owner. That means he is a part of the original crew (since 2009) and has been responsible for establishing the operations. We don’t use that term in the Education-world, but if we did, we would say that Kris Bennet, Heather Earp, Chris Lee, Don Roncska, and Yvette Truman are West Johnston High School plank owners. These five teachers have been at West Johnston since 2003, the first year it was a four-year high school. Plank owners have a way of keeping things even-keeled. I think that every school should have a plank owner plaques!

When I was in high school, my Chemistry teacher Lavonda Ritchie showed me a styrofoam cup that had been sent to the bottom of the ocean and had shrunk. I thought that was the coolest thing ever. But now I have my own styrofoam cup. and bird. and ball. and another cup. I am SOOOOO excited to show my students! Thank you Mrs. Ritchie!!!
Before and after…. our styrofoam birdies shrunk! The picture on the left is before they were sent to the bottom of the ocean. The white, undecorated, styrofoam bird on the right is another way to see how big the birds were before the dive. Increased pressure from all the water molecules pushing down on them at the bottom of the ocean decreased the volume of gas trapped in the styrofoam. The cups and cones (below) were also part of the fun experiment!

Miles and Dorothy launch the drifter!
First, Janice from NC is asking about the drifters! In my first blog I mentioned the Global Drifter Program. Since 1979 countries have been placing and monitoring drifters around the world to better understand and make better predictions . Amanda, Miles and I launched the last of our drifters yesterday.
Sam Ouertani, CIMAS (UMiami/NOAA) Research Associate, provided the following answers to Janice’s questions: How long are the drifters collecting information? > Drifters typically collect data until the drifter runs aground, the batteries die, or the sensors die. Most drifters are able to collect data for 450 days, however they typically lose their drogue within a year. Without a drogue, data from drifters cannot be used to accurately estimate the surface current velocities, but drifters are still able to measure sea surface temperature and other parameters if equipped with additional sensors.
Are there cameras on the drifters? > Unfortunately, Global Drifter Program drifters don’t have cameras but several programs in NOAA have started to add cameras. The National Data Buoy Center has added cameras to almost 100 buoys. I believe the Arctic Buoy Program has started adding cameras to observe sea ice conditions, but footage is not yet available.
Do they collect data about depth of the ocean? >Drifters only collect data at the surface of the ocean; therefore they don’t measure any parameters below the surface, and they do not measure sea floor depth. Another NOAA program, Argo, collects temperature, salinity, and pressure below the ocean surface, but Argo floats do not reach the bottom of the ocean.
Where’s the deepest part? >The deepest part of the ocean is the Challenger Deep, 35,876 feet deep or over 6.7 miles deep, located in the Mariana Trench. Humans measured this depth by lowering a rope from a submersible vehicle.
Thank you Sam for such thorough answers, and thank you Janice for asking! You can find more information about the drifters we launched here.
Second, an answer to the math problem from the last BLOG: On the First Christmas Bird Count, 18,500 individual birds were logged by the 27 participants. On average, 685 birds were seen by each person. That’s a lot of birds! (The numbers 25, 89, and 1990 were not used to solve the problem.) How do you think that number compares to today’s counts?
Engineers Drew, Glen, and Eric on NOAA Ship Pisces
Science at Sea: If steel is heavier than water, how does the 1840-metric ton Pisces stay afloat? Her density, that’s how! The total volume of water she displaces (including steel, people, parts, and air) must have less mass than that same volume of saltwater. Saltwater’s density is 1.025 g/mL, that’s more dense than freshwater, making it easier for you to float in the ocean. You might remember the Titanic sank when it hit an iceberg, ripping the hull and allowing water to enter and add more mass to the ship.
I recently was given a tour of Pisces hull space by the fabulous Engineering Department. They literally make everything run.
Safety is paramount
With ear plugs safely protecting my eardrums, we traveled down into the engine space. Safety is paramount. Fire stations can reach any point on the ship with 2 different hoses. There are 2 or 4 of everything – fire hoses, engines, generators, AC units, proportion motors, you name it – because EVERYTHING needs a backup. There are traditional CO2 fire extinguishers, but I’ve never been to a school that had a CO2 flooding system like the engine room has. Carbon-dioxide (CO2) breaks the oxygen side of the fire triangle by displacing oxygen in the combustion reaction, effectively stopping the reaction. If you were taught to “stop, drop, and roll,” you learned another way to smother the fire. The CO2 flooding system is so powerful that it cannot be used without doing a full body count of the people onboard to make sure no one is in the engine room.
Engineer EricEngineer TravisDorothy tours the engine roomOily water separator
Engineers Eric (left) and Travis (right) show Dorothy how water, electricity, and power are provided
Our first stop was the water maker unit. The water needed for cooking, bathing, and drinking can be distilled from ocean water or processed through reverse osmosis. Both options are available on Pisces. Past the expansion tanks and power distribution units Engineer Eric pointed out the refrigeration system for our Chemistry lab above. We freeze chlorophyll samples taken in one of our CTD projects in an ultra low freezer maintained at -75oC. I was looking at the equipment that was making the freezer work. Air compressors, generators, and motors make the 600-volt electricity on board, step it down to 480 volts for the major machinery, and down even farther to 110 volts for the outlet in my stateroom to charge my cellphone.
Dorothy takes notes during her tour of the engine room
We continued inspecting the machinery that runs Pisces and enables our teams to fulfil our mission. Another piece of equipment that resembles an instrument from our chemistry lab is the centrifuge. It is used to purify the diesel fuel. These pull out the heavier impurities and store water, the lightest part of the mixture, underneath. You might have seen centrifuges at work in the dairy industry. Understanding the science of the engine room helps the science outside the engine room work even better!

More information on Pisces: The ship is 206 feet long, is capable of trawling up to 6,000 feet, and can lift 8,000 pounds. She also has a “quiet hull” which helps reduce underwater sound. Maybe that’s why the whales and dolphins get so close?!
Feel the power!
You do the Math: If each of the engine’s cylinders displacement is 51 liters, and it has 12 cylinders, what is the total displacement of the engine? Compare this with a car engine which holds 2-3 liters. Check in the next blog post for the answer.
To increase the speed of the ship requires an increase in power, but this is not a directly proportional relationship. Doubling the speed requires the power to be cubed. Engineer Eric described the importance of understanding fuel use on ships, math is money! Large container ships easily spend $300,000 a day on fuel. Saving 1% translates to $30,000 savings.
Styrofoam science experiment…. submerged 500 meters…. inverse relationship between pressure and volume predicts the air pockets in the styrofoam will decrease when the pressure is increased. What do you think will happen?
Interesting Things: I am surprised by the ways I have been prepared for life on a boat by classroom life in a public school. At West Johnston High School, in Benson, NC, we have fire drills at least once a month. On a boat, we have safety drills at least once a week. The horn blows a series of long and/or short blasts to let us know if there is a fire, a “MAN OVERBOARD”, or if we need to “ABANDON SHIP!”
Everyone must get into their Gumby suit in less than a minute during an emergency fire drill. The FRB (Fast Reserve Boat) practices the man overboard rescue!

Career Spotlight: Meet NOAA Ship Pisces’ new CO! Commander Sinquefield.
Commander Sinquefield, NOAA Ship Pisces
Did you know there was a Change of Command last month? Our new CO brings a wealth of knowledge and a desire to be a good leader. He showed me around the bridge this week and shared some of his background (BTW, the view on the bridge is amazing!). CDR Sinquefield’s command philosophy is to respect yourself, respect your shipmates, and respect your ship. Likewise, take care of yourself, take care of your shipmates, and take care of your ship. He believes in personal communication and fresh air.
The things he likes about being CO? He likes seeing things you just can’t see on shore, the continuity of historical traditions (like the language, for instance the word “starboard,” has had meaning for 1000 years), training, the opportunity to put into action leadership skills that he was taught and learned through leaders he admired, and regulations. OK, regulations might be pushing it, but he did say he had great respect for the loss of life that has prompted many of the regulations in the shipping industry today.
Growing up in Mississippi, he joined the Coast Guard to complete the trifecta of working in cotton fields, chicken plants, and river tugboats. CDR Sinquefield worked on three different ships while in the Coast Guard, hauled more 80-lb batteries up Alaskan mountains to replenish navigation lights than he’d care to remember, and became familiar with NOAA projects that informed fisheries reports on the west coast. He left the Coast Guard as ship assignments became highly competitive as the service was taking older ships offline at a greater rate then they were being replaced. He left the USCG and he joined NOAA as a civilian, later joining NOAA’s uniformed service, the NOAA Corps.
CO teaches the teacher about maps available for navigation. ENS Howsman (top right) stands watch on the bridge. The center of the circular device (bottom right) spins so fast during cold weather it keeps the area ice free.
CDR Sinquefield was able to earn his commercial shipping license, but doesn’t plan on driving a Mississippi tug boat anytime soon. He stands firm with NOAA’s of 10,000 people, 7 line offices, 15 research and survey ships, and 10 specialized environmental data collecting aircraft. The extraordinary mammals – we’re talking seals and blue whales here – affirm his career choice every. single. day.
Personal Log
Life on is very different from life on land. We work 12-hour shifts. Everyone gets to walk to work – I take 53 steps (10 of them are down 1 staircase) from my cabin door to the door of the dry lab. I take 19 steps to the mess hall for lunch and dinner. There are 67 steps (up 3 staircases) from my door to the Flying Bridge where I see gulls, Mola mola, a full view of the sun in the day, and a sky load of stars at night. I am there now, working on this Blog post when I am not distracted by nature.
Dorothy “working” on this BLOG on the Flying Bridge
One thing that is the same on a boat is the need to wash clothes (probably more frequently since everything had to fit in a carry-on bag and I needed that fleece sleeping bag just in case!). Here is a picture of the laundry room. The ship has 3 washers, 3 dryers, and all the detergent you need.
Dorothy checks out the washer and dryer on board. Detergent is provided. The most important rule when using is to clean out the dryer lint trap before AND after using. Extra Credit if you can tell me why!

First, A blog-reader texted me to say that it looked like I was having fun! Yes, while NOTHING could be more fun than your birthday party, Teacher-At-Sea is at the top of the list of fun teacher-things to do! I hope that ALL teachers, especially those from North Carolina, will apply to be a NOAA Teacher at Sea as we continue to grow strong STEM ecosystems while helping our communities make informed decisions. Thanks for reading Elaine!
Second, an answer to last BLOG’s math problem: If 1 knot = 1.15 mph, and the ship is traveling 8 knots, a stop 15 miles away will take us a little over 1 and a half hours (about 1.6 hours) to reach.
Allison Black, NOAA Seabird and Marine Wildlife Observer
Science at Sea
Animal monitoring is an active part of our floating weather station. A dolphin sighting texted through WhatsApp brings lots of off duty folks up to see. The NOAA Corps on the bridge keep a constant vigil to make sure we don’t hit a whale. But the “Seabird and Marine Mammal Observers” are a functional part of our Science team. They spend their daylight hours on the Flying Bridge scanning the horizon and recording their findings. The species, group size, and photos are catalogued and stored for long term monitoring. This data can be used to estimate bird and mammal abundance in the Northwest Atlantic Ocean now as well as set baseline data through AMAPPS (Atlantic Marine Assessment Program for Protected Species). NOAA Scientists are conducting surveys and developing abundance and distribution models to better understand how protected species such as whales, dolphins, and sea turtles use our waters.

Career Spotlight
Cameron Cox has been able to turn his love of birdwatching into a career. As a Seabird and Marine Mammal Observer Scientist on NOAA Ship Pisces, he can be found on the Flying Bridge during the daylight hours.
Cameron Cox, NOAA Seabird and Marine Wildlife Observer
Cameron’s passion for birding kinda snuck up on him. He remembers hiking with a neighborhood friend who had started birdwatching for a hobby. At age 13, Cameron was hooked. Since he was homeschooled, Cameron was able to carve out time to pursue this new interest. He spent his 20’s traveling around the United States looking at birds. He had a 2-thousand-dollar car and 6-thousand dollars worth of optics – binoculars, camera, and spotting scope.
Cameron explained to me that the long term monitoring projects are hard for Universities and non government organization (NGOs) to fund, which is why our NOAA work is so valuable. The data sets are free and readily available to everyone. Unfortunately, when the BP Deepwater Horizon oil spill decimated the Gulf Coast, there wasn’t baseline data available for recovery and accountability. He was able to assist in creating possible baseline data by performing Seabird and Marine Observations off the coast of Florida, a similar ecosystem.
These days, Cameron leads birdwatching tours in what he calls “Environmental Entertainment.” He loves watching others connect with the importance of the natural world, and hopes to help them become conservationists. Cameron has also published two books, Terns of North American: a Photographic Guide, and a Peterson Reference Guide to Seawatching: Eastern Waterbirds in Flight, co-written with Ken Behrens. Writing at the rate of one book a decade, his ongoing projects will ensure he has a long life! This is Cameron’s first time being a Seabird and Marine Mammal observer with NOAA. We hope it is not his last!

Interesting Things: The Seabird and Marine Mammal Scientist Observers onboard are monitoring lots of animals specifically, but there are other animals we are studying or just find in our nets.
Engineer Drew found this crab in our sea strainers (they strain the water used around the engines). ET Alex named her Crustacina (spelt like crustacean, but pronounced like Cristina). We will keep her on-board until we can get to more shallow waters for release.
NOAA Scientists are collaborating with a group in Miami to study ocean acidification on pteropods’ shells. The phronima amphipod (see video below) inspired the movie alien. They commandeer a salp, eat the flesh, and then lay eggs in the empty pouch.

Have you heard of or participated in the Christmas Bird Count (CBC)? Started in 1900 by 27 dedicated birders, this GOAT Citizen Science Project provides long term data sets that help conservation biologists of all forms study long term bird health and guide conservation actions. The CBC is one example of how good can win (Side Hunt, no link will be provided). Consider joining a Christmas Bird Count this year to learn more about Citizen Science and the importance of long term data sets (see CBC ).
You do the Math: The First Christmas Bird Count was held December 25, 1900. If 18,500 individual birds representing 89 different species were logged by the 27 participants, how many different birds were seen (on average) by each person? Check in the next blog post for the answer.
These styrofoam birdies are going to be a science experiment of their own…. stay tuned!

First, A blog-reader reader emailed to ask me why they put tennis balls on the chairs in the mess hall. Their guess was that it keeps the chairs from sliding. What do you think? Should I ask the captain? Thanks for reading and asking questions!
After a CTD collection, Dorothy watches the sunset
The BRIDGE: where the driving happens……
Second, an answer to the math problem from the last blog: If I filtered water from 3 CTD Rosette bottles for 12-minute protocols at 100 stops, then I would spend 2.5 days just on that project. (Yes, I could spend a fraction of a day on a project.)
Science at Sea: This Summer EcoMon cruise is collecting data that will be analyzed to support NOAA’s mission to protect, restore and manage the use of living marine, coastal, and ocean resources through ecosystem-based management. Our planned path through the northwest Atlantic Ocean, from Rhode Island to Cape Hatteras to the Gulf of Maine, is shown in the map below. NOAA Ship Pisces is a floating weather station, reporting temperature and weather data (available on the Windy app).
Once we embarked, NOAA Corp members and Scientists evaluated weather data to determine it was preferable to go north before heading south. So, we are now in the Gulf of Maine, one of the most biologically productive marine ecosystems and possibly one of the most rapidly warming.
Unique bathymetry (that’s topography, but under water) of the area is shaped by the mixing of cool freshwater from the Arctic, the Labrador Current, and over 60 Nova Scotia to Cape Cod rivers with warmer salty Gulf Stream currents. Referred to as a semi-enclosed sea, the Gulf of Maine has shallow and deep areas such as the Bay of Fundy and Georges Shelf. As our polar ice cap melts, the Labrador Current and the more-shallow rivers become warmer. Warming temperatures strengthen the Gulf Stream. The “bath tub” effect for the Gulf of Maine translates to warming at nearly three times the global ocean average. (Read more about the Gulf of Maine and Acadia National Park’s 60 miles of coastline and 18 islands in the U.S. National Park Service here )
We have had to maneuver around humpback whales and tons of lobster pots to reach our stops and collect data that will better help scientists understand and manage this important ecosystem. But when we talk about how fast we are going, those steering the ship use the unit of “knots” instead of mph. Why?!
Screenshot Photos of Dorothy’s phone: Google Maps isn’t very helpful in the ocean!
Interesting Things: Mariners (and aviators) don’t have road maps or Google maps to steer them. They must navigate using latitude and longitude readings, based on the circumference of the earth. One nautical mile is equivalent to one minute of latitude, and one nautical mile per hour is then called one knot. NOAA Ship Pisces cruises at around 8 knots between stops. My land-based brain is still trying to convert!
On the bridge, our NOAA Corps is constantly figuring out speed, time, and distance problems to make sure the Pisces is getting where it needs to be on time, or how we’ll pass with another vessel. LT Urquhart posts the stations for the following day in our “Plan for the Day” Communication.
You do the Math: If 1 knot = 1.15 mph, how long (in hours) will it take us to get to the next stop, 15 miles away? Remember, the ship is traveling at 8 knots. Check in the next blog post for the answer.
Career Spotlight
LT Karina Urquhart
LT Karina Urquhart is a part of the Ship’s NOAA Corps. In other words… She gets to DRIVE THE SHIP! (NOAA Ship Pisces currently has seven NOAA Corps officers, collectively called the Wardroom.) A fascination with the ocean and a strong work ethic developed through years of competitive swimming propelled her into this role. Growing up in Sanford, Maine, she began swimming in elementary school. While she appreciated the access to deep family roots, her mom also grew up in Sanford, she chose to leave Maine to attend college and continue swimming. (She didn’t especially enjoy academic studies, but figured the classes would take care of themselves. Right?)
Graduating from Clark University in Massachusetts with a degree in Environmental Science Conservation Biology and a minor in Studio Art, LT Urquhart returned to Maine summer beach lifeguarding and then found a USDA Pathways Internship in Washington, DC. The lifeguarding and internship experiences, especially spending 8-hour shifts with a colleague observing ocean currents and movements, set the stage for her NOAA Corp Basic Officer Training Class (BOTC) application. Once accepted, she was trained in ship handling and navigation to prepare her for her role as an Officer in NOAA.
BOTC provided many opportunities to sharpen her problem solving and perseverance skills. She often said, “I can do one more week of this,” and then, at some point, it got better. Her first ship assignment was on NOAA Ship Rainier, for 2.5 years, where she conducted hydrographic operations from Alaska to Guam. LT Urquhart took the technical foundation she gained from Rainier and then rotated into a three-year land assignment at NOAA’s National Center for Coastal Ocean Science (NCCOS) where she supported seafloor and lakebed habitat mapping. While working full time, she pursued a master’s degree in Geographic Information Systems, or GIS, from the University of Maryland.
As advice for people starting a new opportunity, LT Urquhart suggests leaning into the things that scare you the most because they’ll probably help you grow the most. It’s scary for a reason. If you feel stressed or overwhelmed, she suggests doing the thing that you don’t want to do first. Sometimes you just have to get over it and sometimes you have to be the person pushing yourself. LT Urquhart credits her experiences in NOAA with helping her distinguish between the challenges she can overcome, when to ask for help, and when to take a step back.
As one of two Operations Officers on board Pisces, LT Urquhart invests in the crew and scientists on our EcoMon mission, making sure we have what we need so that our mission runs as smoothly as possible. She prints the daily “Plan of the Day” listing the stops and times we’ll be collecting samples. She begins by asking “where do I think we’ll be at midnight?” and “Is this 24 hours worth of stations + transits?”. She credits our electronics and Navigation Officer (ENS Cheney) for doing much of the leg work (and math!) for the team. One tool she says that she couldn’t live without are the RADARs– the ship’s eyes that let us see objects and hazards way further than we can actually see. I’m personally glad that she has her camera. While taking pictures is not a part of her official duties, you may have noticed I’ve posted LT Urquhart’s photos in some of my blogs.
Currently, LT Urquhart is reading The Hero Within by Carol S Pearson and On Character by Stanley McChrysal. Two books she would highly recommend are Indianapolis: The True Story of the Worst Disaster in U.S. Naval History and the Fifty-Year Fight to Exonerate an Innocent Man, by Lynn Vincent and Sara Vladic and The Curve of Time, by M. Wylie Blanchet. I enjoy reading her daily updates. Thank you for communicating so well!
Personal Log
Here are some pictures of my cabin (called a stateroom). In the last blog, I posted some amazing pictures taken by my cabinmate Alyssa. Since we are working opposite shifts, we each feel like we have a private stateroom! While I think I am the oldest person onboard, Alyssa (a college student) is the youngest. I wonder if she can share more information on NOAA scholarships, internships, and volunteer opportunities available to college-aged students? Maybe we should ask….

Isn’t it nice to have so many great photographers in one place? It has been said that a picture says a thousand words. Come meet a member of the science team who has published two bird books in my next blog…
