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!

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).

a map of the station locations. the x axis ranges from 76 degrees West to 64 degrees West and the y axis ranges from 35 degrees north to 45 degrees north. We see the coastline from North Carolina's Outer Banks to Newfoundland. sample locations are marked with blue dots (bongo only stations), red dots (911 + CTD deployments) and red dots with black circles (both). A few green dots denote bongo sampling locations near wind energy areas.

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….

Science and Technology

Environmental DNA

NOAA fisheries research vessels often work with colleges to help provide experiences for the students by allowing them to come on the ship to collect data for their research. On this leg, Makaila Hernandez was aboard to collect environmental DNA (eDNA) under Dr. Alexis Janosik for the University of West Florida. Water samples are taken from different sampling sights in the Gulf of Mexico. Environmental DNA tells scientists what organisms are in the area of water. DNA can be found in the water when organisms shed materials such as the skin, scales, feces, mucous, and gametes. Once the water is collected, a lab will extract the DNA from the water. The extraction is done in such a way that only the purest form of DNA is obtained. It will then be amplified so that it can go through the DNA sequencing process for organism identification. Collecting DNA for the purpose of knowing what organisms are present is done for several different reasons. It helps check the biodiversity and compare the health of the ecosystem to the previous years.

Makailyn stands at a workbench in the ship's lab. Wearing blue latex gloves, she slides two sample tubes into a plastic bag. On the bench nearby is a squirt bottle with a curved spout. It's labeled, but we can't read the writing. Other cardboard boxes and crates with sampling gear surround the work surface. — Makailyn working on eDNA samples

NOAA Ship Pisces

On this mission we have 28 people aboard Pisces. Without the engineers, technicians, deck crew, and the NOAA corps, the scientists wouldn’t be able to do their job. As most of you know, when things go wrong with a vessel out in the ocean, you have to rely on those within. The engineers work hard and I haven’t gotten to talk with them as much as I would have liked, but after all they have been busy down below keeping the ship going. While touring and visiting the bridge, the amount of technology there and knowledge from the officers on maneuvering the vessel is astonishing. I even had a slight go at it, and with the waves and current my travel line was a bit everywhere and not even close to being as straight as theirs. No worries, they were right by my side the whole time.

Drew grew up in Montana and has been working for NOAA for around 18 years. Drew has worked his way up through the years, and the knowledge he knows about how to keep everything on this ship running is incredible. I had no idea there was so much down below us, and the amount of things that have to be checked and continuously working to keep this working vessel going. Drew tried to summarize all the things he did to me from operating all the equipment (including plumbing, HVAC, engine), maintaining all of the equipment, and every 2 hours all gauges have to be completely checked. At midnight a full report of how much fuel is being consumed as well as other things. Drew said some challenges he has had to deal with are bad weather, flooding, and having to fix multiple things at once. Drew states that working hands-on, growing up with a dad as a mechanic, and taking welding vocational classes really helped him, but training today can be done by attending a maritime school.

Personal Log

Today is our last day at sea. Later this evening we will start working our way towards Pascagoula, MS. We are finishing up our last camera drops and preparing to disembark. I can already tell this morning by looking at the water that we are getting closer to Mississippi. The coloration of the water is more of a brown hue than blue due to the Mississippi River meeting the ocean. Several deck crew are making last minute plans as we prepare to port. I have met so many amazing people from all walks of Earth, and listening to their stories and how they ended up on Pisces is remarkable. There are a lot of hard-working and dedicated people who keep this ship running.

I can’t believe I have been on the ship now for two weeks. I have several more questions from my students back home that I can’t wait to answer when I get back. When I return there are only 10 days of school left, so it will be a whirlwind. I have been blessed to have experienced this, and I have learned so much that I hope to inspire my students to dream big and put themselves out there. I told them before I left how nervous I was and that blogging for the first time ever and doing the unknown was way out of my comfort zone. However, hopefully I have taught them that it is important to take chances and pursue things that they want to do even though they may seem scary. My hopes are to also talk about all the different career paths involved in keeping this mission going aboard NOAA Ship Pisces.

Boarding NOAA Ship Bell M. Shimada

August 12 – August 25, 2022

Mission: Pacific Hake Survey

Geographic Area of Cruise: Coastal Washington

Date: August 16, 2022

Weather conditions from the bridge:

Latitude: 4539.9729N
Longitude: 12422.9606W
Temperature: 67.64°F
Wind Speed: 12.62 mph
Barometer: 1017.2 mb

Science and Technology Log

NOAA Ship Bell M. Shimada was built by VT Halter Marine, Inc. in Moss Point, Mississippi. The ship was commissioned on August 25, 2010 and is currently homeported at NOAA’s Marine Operations Center—Pacific in Newport, Oregon. The ship primarily studies a wide range of marine life and ocean conditions along the US West Coast, from Washington state to southern California.

The ship’s design allows for quieter operation and movement through the water, giving scientists the ability to study fish and marine mammals without significantly altering their behavior.

Bell M. Shimada conducts acoustic and trawl surveys. For acoustic studies, the ship uses a multibeam echo sounder (MBES) that projects a fan-shaped beam of sound that bounces back towards the ship. The ship’s MBES, one of only three such systems in the world, acquires data from both the water column and the seafloor. Scientists can detect fish when the boat passes over them, measuring the signal reflected by the fish to estimate their size and number. The system can also create a map and characterize the sea floor.

Hydrovents?

The ship conducts trawl sampling with a standardized, three-flange, four-seam bottom survey net equipped with a skipping rock sweep: sweeps with large rubber discs that allow the nets to be towed over rocky and uneven seabeds. Trawls sample fish biomass in a given study area. This helps scientists learn what species are in observed schools of fish and collect other biological data.

The ship’s wet lab allows scientists to sort, weigh, measure and examine fish. Data is entered directly into the ship’s scientific computer network. The Bell M. Shimada Bird and Marine Mammal Observation Stations are equipped with sensors to help researchers identify and track protected species.

Gear to use in wet lab

Bell M. Shimada was named by a team of students from Marina High School in Monterey, California, who won a regional NOAA contest to name the ship. The ship’s namesake served in the Bureau of Fisheries and the Inter-American Tropical Tuna Commission. He was known for his contributions to the study of tropical Pacific tuna populations, which were important to the development of West Coast commercial fisheries after World War II. Bell M. Shimada’s son, Allen, is a fisheries scientist with NOAA Fisheries.

Personal Log

This has been an experience that I never imagined, on Thursday, August 11, when I entered the port and saw the ship in the distance, I felt a lump in my throat, it is much larger and more imposing than I imagined. The scientist in charge of the expedition, Beth Philips, welcomed me to the ship. She was extremely jovial and pleasant and gave me a tour of the ship, which let me tell you, this is a labyrinth. The crew has been excellent, all with a kind and respectful treatment towards me. On the other hand, I hope I can loosen up a bit more with everyone on the ship since I’m a bit in my head because of my English speaking.

I want to introduce you to the excellent team of scientists

Science Team: John Paul, Ethan Beyer, Toby Auth, Steve de Blois, Michael Gutiérrez (me) and Beth Phillips
Celebrating Beth’s Birthday!

In just a few days of meeting them, they have taught me a lot. They have all been patient and have explained and answered questions regarding the work they do on the high seas. Their knowledge and experiences have led me to create great admiration for them. In the next blogs you will learn more about each of them and you will see them in action!

Not Just One, But Two Puerto Ricans on the High Sea!

That’s right I’m not the only Puerto Rican on NOAA Bell M. Shimada, this is LT Erick Estela from Ciales, Puerto Rico. Erick is one of the NOAA Corps officers serving at sea, on land and in the air to support NOAA’s environmental science and management mission. Erick have been serving with NOAA Corps nine and a half years. We met in the middle of a drill and it was very exciting to know that there’s another Puerto Rican on board. Puerto Rico is proud to have Erick in such an important role within NOAA!

Science and Technology Log

The ship is driven from the Bridge. It is the main control center of the ship. It is driven by a variety of people and computers. People who drive the ship include: the Commanding Officer (CO), Conning Officer (CONN), Officer of the Deck (OOD), and several helmsmen. There are several (at least two) people on the Bridge all the time. If Thomas Jefferson were a six-story building, the Bridge would be on the top floor. Being on the 6^th floor has its pros and cons. Seeing, avoiding, and communicating with other boats in the area is very important. One can see far and wide from up there! One disadvantage is that things really rock ‘n roll up there when we are in heavy seas!

According to a popular career website (Your Free Career Test), “A ship captain is in command of water vessels in lakes, oceans, coastal waters, rivers, or bays. They ensure the safe and efficient operations of vessels. A ship captain navigates their vessel according to weather conditions and uses radar, depth finders, radios, buoys, lights, and even lighthouses. They determine sufficient levels of oxygen, hydraulic fluid, or air pressure of the vessel.”

Are you interested in having a career as a ship captain of a seagoing vessel? Watch the following video to see if you have what it takes!

How about a career at sea?

view of the bridge controls — *The Bridge* has many windows, and is filled with instruments, computers, and reference manuals.

Following are pictures of what is used to navigate and drive the ship. Each picture is followed by a brief description.

a radar screen — *Thomas Jefferson* has two radars

Radar is one of the most important tools on the Bridge. It allows us to see objects, ships, obstructions – basically anything we could run into (on the surface). TJ has two radars. The X-band radar is used for higher resolution pictures and things in closer range. The S-band radar is used to see objects further away.

The Officer of the Deck (OOD) and Conning Officer (CONN) use the Automatic Radar Plotting Aid (ARPA) function of the radar to identify “targets” or other ships in the area. It is used to track their relative motion to see which way and how fast they are headed with respect to TJ. The ARPA calculates the closest point of approach (CPA) and time to CPA. This tells you if there is the potential of a collision. The result is to change course, change speed, contact the other ship, or anything to reduce the risk of a collision.

If there is the potential for a collision, the OOD or CONN may contact the vessel and make a passing arrangement. However, since TJ is conducting operations, they may also make a Security announcement to let other vessels know their whereabouts and status. (Sécurité is French for “security” and is pronounced se-cur-i-tay.) According to Wikipedia, “Of the three distress and urgency calls, Sécurité is the least urgent.

Sécurité: A radio call that usually issues navigational warnings, meteorological warnings, and any other warning needing to be issued that may concern the safety of life at sea yet may not be particularly life-threatening.

Pan-pan: This is the second most important call. This call is made when there is an emergency aboard a vessel, yet there is no immediate danger to life, or the safety of the vessel itself. This includes, but is not limited to injuries on deck, imminent collision that has not yet occurred, or being unsure of vessel’s position.

Mayday: This is the most important call that can be made, since it directly concerns a threat to life or the vessel. Some instances when this call would be made are, but not limited to death, collision, and fire at sea. When the Mayday call is made, the vessel is requiring immediate assistance.”

Last evening, the CONN made a Sécurité announcement because the position, direction, and speed of a dredging vessel and the TJ were at risk of a collision. As soon as the announcement was made, the dredging vessel altered its course and the TJ slowed down a bit. We averted the collision with a very large margin.

A close-up view of one portion of the radar readout (green and yellow numbers on a black background) — *A close-up view of one portion of the radar.*

Above is a close-up view of just one portion of the radar.

HDG = Heading of the ship (per gyrocompass)

SPD = Speed in knots

COG = Course over ground ***

SOG = Speed over ground ***

The yellow numbers represent degrees of latitude and longitude.

(*** These parameters are course and speed after the influence of wind and current have been taken into account.)

Speed at sea is measured in knots. One knot is a unit of speed equal to one nautical mile per hour or approximately 1.15 miles per hour.

Distance at sea is measured in nautical miles. The nautical mile is based on the Earth’s longitude and latitude coordinates, with one nautical mile equaling one minute of latitude. A nautical mile is slightly longer than a mile on land, equaling 1.15 land-measured (or statute) miles.

*A combination of monitors showing and Electronic Charting System (ECS) and the Electronic Chart Display and Information System (ECDIS)*

The lower monitor and keyboard are the Electronic Chart Display and Information System (ECDIS). It displays Electronic Navigation Charts (ENCs). This system allows officers on deck to see where they are in real-time. It can be updated frequently when new information regarding navigation (buoys, obstructions, depths, etc.) are charted. It has all but replaced paper carts.

a control panel — *Search lights and communication systems*

The two panels on the left control the starboard and port side searchlights. Upper right is a fathometer. It is the less sophisticated echo sounder used to measure depth below the keel when we are transiting (moving from place to place) and not surveying.

Lower right, you will find the intercom that is used to communicate between the Bridge and the Data Acquisition desk in the Survey room.

close-up view of a radio control panel — *This communications VHF radio is set on channel 16.*

This radio is used to communicate with other ships in the area. Information to and from the US Coast Guard is also shared through this device.

computer monitor — *This monitor shows where data have been collected.*

This monitor shows what is going on with a software called “Hypack”. It displays data that has been collected. It helps hydrographers and those driving the ship to visually keep track of where data has been collected. Also, it feeds information to the autopilot which allows the ship to stay on the course while surveying, without having to steer in hand or adjust based on distance from the line.

ship's steering wheel, or helm, mounted on bridge — *The ship’s wheel*

This is where the Helmsman stands and steers the ship. The Helmsman takes his/her orders from the Conning Officer. This officer is responsible for instructing the helmsman on the course to steer. Did you know that ships have autopilot? The helmsman steers the ship when it is turning or doing complicated maneuvers. When the ship is traveling in long straight lines (when we are “mowing the lawn”), the helmsman turns on the autopilot affectionately called, “Nav Nav”. It is called this because the Nav button needs to be pushed twice to activate the system.

control panel — *This panel controls the power of the main engine that turns the propeller.*

control panel for the bow thruster — *The bow thruster control panel*

There is a small propeller on the bow called a bow thruster. This panel controls the thruster. It is often used when steering the ship in tight places at slow speeds. I like to think of it as a way to “fine tune” the direction of the ship.

There are many compasses on the ship.

This is the magnetic compass that hangs from the ceiling of the Bridge.
This is the LED display of the main compass used in navigation. It uses gyros.
This is a gyrocompass repeater that allows watch standers to take bearings to other vessels or significant points on land. There is one on each side of the bridge.

How did early people navigate the oceans?

The rudder is found aft (behind) of the propeller. Both are under the ship. The helmsman uses the rudder to turn the ship right or left. The rudder moves using hydraulics. The pointer on the display above moves as the rudder moves.

This dial displays the position of the rudder. The rudder is used to turn the ship.
This gauge is physically attached to the rudder.
The rudder is moved using opposing hydraulic systems.

Personal Log

We have had beautiful weather during this leg of the mission. This morning, we had a beautiful red sky at sunrise.

sunrise over Lake Erie; wake of ship visible — *Red sky in the morning? Should I heed warning?*

You may be familiar with the saying, “Red sky at night, sailor’s delight. Red sky in the morning, sailor’s warning.” The Library of Congress states that this concept is also repeated in Shakespeare and in the Bible.

In Shakespeare’s play Venus and Adonis, “Like a red morn that ever yet betokened, Wreck to the seaman, tempest to the field. Sorrow to the shepherds, woe unto the birds, Gusts and foul flaws to herdmen and to herds.”

In the Bible (Matthew XVI: 2-3,) Jesus said, “When in evening, ye say, it will be fair weather: For the sky is red. And in the morning, it will be foul weather today; for the sky is red and lowering.”

Weather lore has been around since people have needed to predict the weather. Several agencies (NOAA Earth Systems Research Laboratory, Earth Observatory at NASA, and University of Wisconsin-Madison) have studied the science behind this piece of weather lore.

According to the Library of Congress, “When we see a red sky at night, this means that the setting sun is sending its light through a high concentration of dust particles. This usually indicates high pressure and stable air coming in from the west. Basically, good weather will follow.

A red sunrise can mean that a high-pressure system (good weather) has already passed, thus indicating that a storm system (low pressure) may be moving to the east. A morning sky that is deep, fiery red can indicate that there is high water content in the atmosphere. So, rain could be on its way.”

The beautiful sunrise + the NOAA weather report caused people to believe that we might be in for a weather change.

Looks like rain is coming! Batten down the hatches!
Rain clouds in the distance.
After a morning of surveying closer to shore, the launch came home to roost just in case of bad weather.
Right before the rain hit, I saw a monarch butterfly off the stern of the ship. We were about 5 miles from land. (Full disclosure – I did not take this picture.)
Heavy rain, wind, lightning, and higher waves. Weather decks were secured. This meant that no one could go outside until further notice.
The ship’s whistle is sounded one prolonged signal (4-6 seconds) every 2 minutes indicating that we are in an area of reduced visibility.

For the Little Dawgs . . . (Part 1)

Q: Where is Dewey? Hint: Only a very important person on board is allowed to sit in this chair.

Dewey the beanie monkey sits on a leather chair — *Dewey, have you gotten permission to sit there?*

A: Dewey is sitting in the captain’s (Commanding Officer’s) chair in the Bridge. CO Jaskoski gave Dewey permission to sit in the chair . . . just this once because he is so cute.

For the Little Dawgs . . . (Part 2)

Q: Where is Dewey? Hint: This is used by the helmsman to drive the ship.

Dewey the beanie monkey propped up on the helm — *Hang on Dewey! I am afraid that you are too short to do the work of a helmsman.*

A: Dewey is sitting on the wheel in the Bridge. Yes, I am afraid that he is too short to do his job.

Human-Interest Poll (HIP)

graph of responses to poll: What do you like to do in your free time while on the ship? Read (7 people), talk with family (4), work out (3), play video games (3), other (3) — Other = writing letters, napping, or planning future vacations

Questions from students:

Casey M. asked, “Have you found anything shipwrecks yet?”

LG – Whether we have found something or not, I must respond the same way. It is classified information. I am not allowed to tell you whether we have or have not found anything until I am given permission to do so. Thank you for your curiosity.

Evelyn A. asked, “Have you seen anything that you haven’t seen before on Lake Erie. Also, what is the deepest spot you have seen so far?

LG: During this leg of the survey the deepest we have measured is 28 meters (~ 92 feet) deep. I asked one of my shipmates and she said the deepest she has measured is 999.8 meters (3280 ft or over 1000 yards) deep. That’s deeper than 10 football fields!

I’ve had many new experiences and have seen lots of new things on this voyage. The one that stands out for me is that we found a shipwreck. I cannot tell you where we found it – that’s confidential. It was about 70 meters (230 feet) long – a little shorter than a football field. It looked as if it had been there for a long time.

Gretta S. asked, “Do you ever miss being on land or miss your neighbors (Wink, wink)? How was the movie night? How tall is the ship? Have the waves ever gotten so high you could feel the sea spray on the deck? Have you seen both vertebrates and invertebrates?”

LG: Yes, I miss my family, cats, and neighbors, however, this is a voyage of a lifetime! The movie night was great. I didn’t stay up to watch the whole movie – bedtime called. The ship from “keel to wind birds” is about 100 feet. Yes, the waves have gotten high enough to wash up on to the main deck – especially during a turn. I’ve seen a lot of insects (invertebrates) but few vertebrates unless you count my fellow shipmates and some seagulls!

Josie S. asked, “What is your favorite meal on the ship so far? How do you like sleeping on the top bunk in your room on the ship? Did you see any fish in the lake? Are you allowed to have electronics on the ship? I liked the picture of you and Dewey on the ship!!!! You look happy!”

LG: My favorite meal so far has been prime rib and sweet potatoes. I like sleeping on the top bunk because I have a porthole. My bed is very comfy, and my roommate is nice. I have not seen any fish in the lake; however, we see a lot of seafood in the mess hall (examples: crab legs, cod, grouper, shrimp, oysters, and salmon). Yes, we are allowed to have electronics on the ship. I have my cell phone, computer, a small camera for videos, and voice recorder. We use a lot of technology! I am happy! This has been a wonderful learning experience in so many ways. I cannot wait to share this experience with my students when I return to Dalton. (P.S. I will give Dewey a hug for you.)

Janie S. said, “We were at Kelleys Island last weekend! When we were there, we saw Canada with our binoculars! Could you see Canada? What other foods did you have on the Thomas Jefferson ship? The deepest lake out of the great lakes would be Lake Superior. And the shallowest lakes out of the great lakes would be Lake St. Clair and Lake Erie.”

LG: That is very cool that you got the chance to go to Kelleys Island and see Canada. During the day, we cannot see Canada from where we are surveying. The Operations Officer in Training told me that if you go on the bridge at night, you can see radio towers and lights from the windmills in Canada. We are approximately 19 nautical miles (about 22 statute miles) from the nearest point of land in Canada which is Long Point National Wildlife Area in Norfolk County, Ontario. We stay mostly 4 to 8 nautical miles north of Presque Isle, PA. This link will give you all sorts of information about the depths of the Great Lakes. Did you know that Lake Superior is eight times deeper than Lake Erie! As for the part of your questions about what other foods we have on TJ – I decided just to include a panoramic picture of one of our snack shelves. Just suffice it to say that we are very well fed!

Science and Technology Log

We are continuing our path due east. We (they) have surveyed 14 different banks and dropped 102 cameras.

*NERD ALERT*

Along the way we have been collecting water samples that contain environmental DNA (eDNA), and mapping at night. Caroline Hornfeck, graduate student at the University of West Florida, is collecting water samples once daily and at additional fixed sites. She is working under Dr. Alexis Janosik, participating in a multiyear study of reef fish in the Gulf of Mexico with the Florida Fish and Wildlife Conservation Commission (FWC) and NOAA. The project’s goal is to characterize reef fish diversity in the northwest Gulf of Mexico using molecular tools and techniques.

Environmental DNA is a molecular tool used in aquatic ecosystems. eDNA contains DNA from all organisms in the water column. This DNA can be in the form of gametes (reproductive cells), fish scales, waste, etc. This approach is noninvasive and cost-effective, and does not require contact with the organism. Caroline collects test tubes of water, adds some magical juice that causes a chemical reaction, and the DNA begins to solidify in the test tube. You with me? THIS is real science.

Later in the lab, the eDNA is extracted and the samples are run through polymerase chain reaction (PCR). PCR amplifies (multiplies) genes and the sample is sent to a lab for additional science. Fancy technology makes millions of copies of the DNA. You piece it all together and use the data to assess reef fish diversity. Essentially, eDNA is like taking attendance in the reef community. Roll call.

I will leave it at that, though it’s much more complex. I am starting to remember why I avoided molecular biology. Caroline, I’m impressed.

Meet the Science Crew

Paul Felts
Field Party Chief, Fisheries Biologist

Field Party Chief Paul Felts holds up two fish sampled during the reef fish survey

What do you enjoy most about your job? “It’s the field work that I enjoy most. I love being out on the water (in moderation), participating in the various surveys. I have been a part of so many fun surveys – reef fish, snapper longlines, trawls, plankton, and mammals. I appreciate getting a break from the desk, reviewing footage, and annotating the research. I also enjoy working with the crew and building team camaraderie.”

What is the coolest animal you have seen or worked with? “It’s tough to decide. I have seen all sorts of cool stuff. One mammal survey we were out on the smaller boat and a sperm whale breached about 100-200 yards from the boat. Later those whales were lying on their sides at the surface with full bellies, seemingly just resting after a meal. The giant stingray and thresher shark are up there on my favorites as well.”

Paul is the Field Party Chief. He’s been with NOAA for 21 years. As a Fisheries Biologist at the Southeast Fisheries Science Center, Paul studies fish populations and their impacts. He knows every fish in the sea (or at least close). Out here, Paul coordinates scientific operations. He has to be on every minute of every day, and deal with the crews’ shenanigans, yet still shows up each morning with a smile on his face, ready to take on the day.

Amanda Ravas
Fisheries Biologist

What do you enjoy most about your job? “My favorite part about my job is being out in the field… as long as I’m not seasick. Because I’m still so new, I love learning all the ins and outs of the projects, seeing the species I’ve been watching on our videos in person, and hearing stories from other scientists about all the cool projects they’ve been a part of.”

What is the coolest animal you have seen or worked with? “The coolest animal I’ve seen while out in the field is a manta ray which followed our boat for a few minutes as we were making our transit back ashore. And I always get super excited seeing any shark species while out at sea.”

Amanda is a Fisheries Biologist at the Panama City Laboratory. She’s been with NOAA for two years. She studies fish populations and their impacts. She may be tiny, but she’s mighty. Don’t underestimate her. She knows her stuff, and knows it well, and can keep up with the best of them.

Rafael Ortiz
Program Support Specialist

Program specialist Rafael Ortiz, wearing a hard hat, life vest and gloves, holds a hook over a plastic bucket

What do you enjoy most about your job? “I enjoy being part of the NOAA Fisheries Mission at the MSLABS level. Being an administrator I find myself lucky to participate on various surveys with the scientist. I get to build a great working relationship and many friendships with them. I learn so much from them. Everything from science related topics to personnel life topics. I also feel that they have a higher respect for me than just some admin person.”

What is the coolest animal you have seen or worked with? “Oh so many to list. I’ve seen so much diversity on these surveys that it’s hard to list. I’m always amazed at what comes out of the ocean and the thought of things I’ve not seen or will never see. I’m fascinated by the smallest to the biggest ocean animals.”

Rafael is a Program Support Specialist. He has been with NOAA for seven years. He provides oversight, technical expertise, and support to personnel and field biologists. But don’t let him fool you; he’s a biologist at heart. These scientists are lucky to have him out here at sea. He works hard, and best of all, keeps everyone in good spirits.

Kenneth Wilkinson
Electronics Technician

What do you enjoy most about your job? “All of it. I have done just about every survey – plankton, sharks, small pelagic, reef fish, Caribbean reef fish, and more. I have worked closely with NOAA enforcement, installing vessel monitoring systems and reporting illegal fishing. Surveillance in the Keys was a lot of fun. I enjoyed being down there. Most recently, I operate NOAA drones.”

What is the coolest animal you have seen or worked with? “The first to come to mind is the 12 ft. tiger shark during a longline survey. I also enjoyed building satellite tags and tagging sea turtles.”

Kenny is an Electronics Technician at the Southeast Fisheries Science Center. He has been with NOAA for 32 YEARS. He handles all the equipment from scientific to shipboard navigation and communication. What would we do without Kenny? This survey, as well as most, relies entirely on the technology. Kenny keeps us in check. I mean he’s the only one that knows what a transmissometer is.

Caroline Hornfeck
Graduate Student, University of West Florida

Graduate student Caroline Hornfreck, wearing a hard hat, life vest, and gloves, sits at a desk in the wet lab aligning sample tubes in a styrofoam holder

What do you enjoy most about your job? “What I enjoy most about being a student in this field, is always adapting and learning new skills that can help me grow as a scientist. Whether that’s in the classroom, research lab at the University of West Florida, or aboard NOAA research vessels.”

What is the coolest animal you have seen or worked with? “One of the coolest animals I have seen is a spotted eagle ray. I hope further down in my research career I can work with elasmobranchs (sharks, skates, and rays) and implement better conservation management for keystone species.”

Caroline earned her B.S. in Marine Biology at the University of West Florida. She is pursuing her Master’s at UWF. She is doing real science out here. Are you even a scientist if you don’t collect DNA? This girl is going places for real.

Personal Log

When 2 or 3 o’clock rolls around, I have to shake things up a bit. I’ve started making rounds just to say hello and see what people are up to. I remind folks that what they do is really cool. I make my way to the bridge usually once or twice to bother them a bit. This is where the ship is commanded. It looks like some sort of spaceship up here. I roam around and try to make sense of the many gadgets and screens. Take a peek out the windows. The sun reflects intensely on the water. It’s hella bright out here.

Operations Officer, LT Christopher Duffy, asks “Do you want to drive?” I look over my left shoulder, I look over my right. Oh, he’s talking to me. “Uh, yeah I do.” I have absolutely no clue what I just signed up for. He seems to think I can handle it. I get the run down. The helm is the steering wheel – check. The main engine controls the propulsion – check. Then there are the bow thrusters. From what I understand, they are basically propellers on the side of the boat. I’m not really sure. I just know they improve maneuverability.

Navigation is an art and science. They transit to specific destinations and position and maneuver the ship and make it look easy. Navigators measure the distance on the globe in degrees. If you have forgotten, like I seemed to have, like a circle, the Earth has 360°. Compasses have four cardinal points (directions), right? – North (N), East (E), South (S), and West (W). Well, turns out when you’re real official, you use degrees instead of directions. As if directions weren’t confusing enough. LT Duffy, “When I say 10° right, you do just that and confirm when you’re there.” I can handle that. “Ten right.” I work with LT Duffy to retrieve our next buoy. Huddleston keeps a careful eye. This is fuuunnnnn. “You ready for a hard right?” “Like all the way?” Seems questionable. Oh he’s serious. “Hard right rudder.” SKKKIIIIRRRRRTTTTTTT. Man this thing can move. We Tokyo drift right into position. Nailed it. LT Duffy takes control to finish positioning (I made it easy for him). I’m grinning ear to ear.

“Are you comfortable giving commands?” “Yep.” The overconfidence kicks in. First things first, CONN candy. What’s that you ask? The officers up here have a secret drawer of tasty treats that they’ve been hiding from us this whole time. Gotta have some before taking command. Wait, what am I doing? LT Duffy explains, “You’ll be giving commands to LTJG, Ariane Huddleston, while she steers.” Uhhhhhhh. I see the fear in her eyes. “Just repeat after me.” Huddleston takes the wheel and I “give commands.” It clicks. This is my time to shine. I “very well’d” the heck out of those commands. So much fun, thank you crew!

Did You Know?

You know all those horrid COVID tests you had to take? You were doin’ science right there. The polymerase chain reaction (PCR) tests genetic material (fluid from the nasal swab). The test detects the virus that causes COVID-19. Scientists use the PCR technology to amplify small amounts of RNA from specimens into DNA, which is replicated until SARS-CoV-2 is detectable if present. It’s cool stuff guys.
