Animal monitoring is an exciting part of life aboard our research vessel. It doesn’t take much to spark enthusiasm; an alert comes over the radio (not the loudspeaker because we don’t want to wake the sleeping crew!) about animals sighted near the boat, and the crew pops up to the deck (no, it’s not just Mrs. LaMonte), eager for a glimpse of these charismatic marine visitors. Nick Metheny is the dedicated observer for the Pisces on this cruise survey. He is observing and documenting from sunrise to sunset; that’s some dedication! Meanwhile, NOAA Corps officers on the bridge keep a steady, watchful eye to ensure we safely share these waters with much larger neighbors, including whales.

Beyond these spontaneous moments of excitement, Seabird and Marine Mammal Observers play a critical, structured role within our science team. From their perch on the Flying Bridge, they scan the horizon, tracking everything. Each sighting, species, group size, behavior and any photograph is carefully recorded and cataloged.

These data feed into long-term monitoring efforts, including AMAPPS (the Atlantic Marine Assessment Program for Protected Species). Through this work, NOAA scientists are building a clearer picture of how whales, dolphins, sea turtles, and seabirds move through and rely on these waters. It’s rewarding to know that those thrilling, real-time sightings of these incredible animals are also contributing to critical research, helping us better understand and protect the vibrant marine life that makes every watch on deck feel a little bit magical.

You are likely familiar with the satellites of the National Aeronautics and Space Administration (NASA), although high-tech, the satellites must be carefully validated. During the NOAA EcoMon cruise, we’re helping to ground-truth NASA’s PACE satellite, which monitors phytoplankton. Artem Dzhulai and Rowan Cirivello are Ph.D. candidates in biological oceanography who study how light interacts with the ocean. When the NASA satellite passes over our ship at noon, they deploy a radiometer to measure how light decreases through the water column.

They also collect water samples, either from CTD Rosette casts or the ship’s continuous water line system (more about that in the next blog). In the lab, the samples are filtered to separate particulate matter (such as plankton) and colored dissolved organic matter (CDOM). This is done repeatedly for validation or “triplicates for particulates,” as Rowan puts it. These are analyzed with a spectrophotometer to determine how light and color vary in the water, with some samples sent directly to NASA.

Advances in technology now allow us to deploy sophisticated instruments that can continuously track individual organisms in the ocean. Two Imaging FlowCytoBots (IFCB) are being used to confirm accuracy. Inside the cylinder tanks, images of individual plankton are taken with thresholds set based on backscattering & fluorescence; for example, lower the threshold for pelagic water with fewer organisms and increase it for neritic (coastal) water with a higher abundance of organisms.

Look at how cool it is to see the phytoplankton in real-time!

With these tools, we are not just observing ecosystems, we are witnessing them unfold in real time, opening the door to deeper insight, discovery and innovation in marine science. Ultimately, this work improves our understanding of ocean health and could help fisheries identify productive ecosystems by tracking phytoplankton, the foundation of the marine food web.

Scientific Concepts

Below are some terms you may have learned in a science class before, but are key to understanding why the measurements are being collected as data for the EcoMon survey samples. These parameters, along with nutrients and oxygen, determine the types and abundance of plankton.

Plankton – Don’t doubt the drifters, plankton run the world. Despite their name, rooted in the Greek planktos, meaning “wanderer” because they cannot swim against the current, these tiny powerhouses are anything but passive. They are dynamic, influential forces that quietly orchestrate life on a global scale. From fueling marine food webs to regulating the carbon cycle and even shaping weather patterns, plankton prove that impact isn’t about size, it’s about significance.

Temperature, salinity and density vary with depth – below is a general graph of how scientists might expect parameters to change with depth. In addition to this general trend, scientists will layer in information about a specific location to account for variables such as bathymetry (underwater topography) and latitude. By understanding these general trends, they can determine when changes occur and how they may impact plankton.

Conductivity (salinity) – Pure water conducts electricity very poorly. However, when salts such as sodium chloride (NaCl) dissolve, they dissociate into free-moving, charged ions that readily conduct an electric current. As a result, increasing salinity corresponds to higher electrical conductivity. A CTD instrument captures this relationship using a conductivity sensor, which measures how effectively the water transmits an electrical current, a direct reflection of its dissolved salt and ion content.

Fluorescence – Oceanographers rely on chlorophyll (a) fluorescence as a primary biological proxy to estimate phytoplankton concentration and biomass. Phytoplankton cells absorb blue light and re-emit the absorbed energy as red fluorescence (at around 685 nm), which can be efficiently measured and graphed.

Methodology

The Conductivity, Temperature, and Depth (CTD) is an instrument with several physical and chemical sensors: pH, temperature, salinity, oxygen, depth, and fluorescence that collects data at every station from which we collected fisheries data. On the ship, there are two CTDs: one is attached between the bongos and one is attached at the bottom of the Rosette (a circular instrument with bottles for collecting water samples). Depending on the station’s criteria, both are sometimes deployed.

For this instrument, the ship must be diligent in following protocol; one important job for the Able Body Deck Crew is getting the instrument into the water and maintaining the guidelines for the cable lines’ angle and depth. The NOAA Corps officers radio from the bridge, “10 minutes until bongo” (I have heard this 100’s of times) and the crew begins operations.

In addition to deployment, there are two tasks for this instrument to be completed by the science team: monitoring its deployment in the lab as some data is transmitted instantly and retrieving the water samples that will be processed for additional lab data.

Open valves for the cylinder

Filter water into the sample bottle for chlorophyll
Collect water in glassware for nutrient testing

This data is used alongside catch data collected from the bongos, allowing scientists to make connections between water quality and fish caught. While the relationship is complex, water quality and marine life abundance are directly related. Water quality and the survivability of marine species contribute to our economic, cultural and public health. This data can help identify potential threats and inform management plans for both water quality and targeted species.

The NOAA Ship Pisces has been so welcoming to me as I have become fully immersed in the ship’s daily routine. There is a bulletin board with pictures of the people currently onboard, you can see I am part of the science team, most of whom I have written about or will write about. They even posted a QR to my blog and some of the crew have read along and learned the details of some of the science being conducted onboard. Have I mentioned how much I LOVE the FIRST LIGHT of the day! Just breathtaking. I feel like I am working and on vacation at the same time. For work, I bounce back and forth between washing bongo nets, writing the blog, posting student challenges on Instagram and watching for wildlife. Getting to see so many marine organisms, having delicious choices for breakfast/lunch (also good choices for dinner, but 3 am-3 pm shift, I am already in bed) ready for me and getting to do laundry while I work definitely feels like vacay mode.

Did You Know?

That beautiful Caribbean blue water could be seen from the NASA satellites and it was caused by microscopic phytoplankton. Plankton, specifically phytoplankton, really are in charge! I actually pranked several students into thinking the ship was down in the islands.

Coccolithophores span a broad range of surface environments, from nutrient-rich (eutrophic) waters in temperate and subpolar regions to persistently nutrient-poor (oligotrophic) subtropical gyres. They contribute about 1–10% of primary production and phytoplankton biomass, with their share rising to ~40% during bloom conditions.

Coccolithophores are among the most significant pelagic calcifiers, producing large quantities of calcium carbonate. The shedding drives a sustained flux of carbonate to the deep ocean, supporting vertical gradients in seawater alkalinity and playing a key role in the carbonate pump. In addition, coccoliths enhance the sinking rate of organic matter and improve the efficiency of carbon export to depth. Over long timescales, this has contributed to the formation of a carbon sink; feedbacks between seafloor carbonate accumulation and the carbon cycle help stabilize Earth’s climate.

Science and Technology Log

In my previous blog posting, I explained the importance of plankton as base of the ecological pyramid upon which much of marine life in this ecosystem depends. The past few days, I have witnessed and experienced in-person how scientists aboard this sophisticated research vessel collect and analyze sea water samples for plankton.

Yesterday I spent some time with Kyle Turner, a guest researcher from the University of Rhode Island doing his M.S. in Oceanography. He operates a highly sophisticated device called the Imaging FlowCytobot (IFCB). I was fascinated to learn how it works. It is basically a microscope and camera hooked up to the ship’s water intake system. As the waters pass through the system, laser beams capture images of tiny particles, mostly phytoplankton (tiny photosynthetic drifters). As particles do, they scatter the light or even fluoresce (meaning, they emit their own light). Based on this, the computer “zooms in” on the plankton automatically and activates the camera into taking photographs of each of them! I was amazed at the precision and quality of the images, taken continuously as it pipes in the water from below. Kyle says this helps them monitor quality and quantity of plankton on a continual basis.

Plankton may lack the popularity of the more charismatic sea animals like whales, but much of life in the ocean hinges on their welfare.

Career Corner

Hello, students (especially bio majors). In this corner of my blogs, I will interview some key research personnel on the ship to highlight careers. Please learn and be inspired from these folks.

Here is my interview with Kyle Turner.

Q. Tell us something about your graduate program.

A. My research focuses on phytoplankton using bio-optical methods. Basically, how changes in light can tell us about phytoplankton in the water.

Q. How does this IFCB device help you?

A. It gives me real time information on the different types of phytoplankton in the location where we are. We can monitor changes in their composition, like the dominant species, etc.

Q. Why are phytoplankton so important?

A. They are like trees on land. They produce about half the oxygen in the atmosphere, so they’re super important to all life on earth. They are also the base of the marine food web. The larger zooplankton eat them, and they in turn are eaten by fish, and so on all the way to the big whales. They all rely on each other in this big ocean ecosystem.

Q. How are phytoplankton changing?

A. The oceans are warming, so we’re observing shifts in their composition.

Q. What brought you into marine science?

A. I grew up on the coast. I’ve always liked the ocean. I love science. So I combined my passions.

Q. What is your advice to my students exploring a career in marine science?

A. Looking for outside research opportunities is important. There are so many opportunities from organizations like NASA, NSF, and NOAA. I did two summer research internships as an undergrad. First was with NASA when I was a junior. I applied through their website. That was a big stepping stone for me. A couple of years later, I did another summer project with a researcher who is now my advisor in graduate school. That’s how I met her.

Q. What are your future plans?

A. I’d love to get into satellite oceanography to observe plankton and work for NASA or NOAA.

Personal Log

I am pleasantly surprised by how comfortable this ship is. I was expecting something more Spartan. I have my own spacious room with ample work and storage space, a comfortable bed, TV (which I don’t have time for!), and even a small fridge and my own sink. Being gently rocked to sleep by the ship is an added perk!

The food is awesome. We have two expert cooks on board, Margaret and Bronley.

The ship’s mess is a nice place to eat and interact with people. There’s always food available 24/7, even outside of meal hours.

Did You Know?

NOAA Ship Gordon Gunter played a big role in recovery operations following Hurricane Katrina and the Deepwater Horizon oil spill.

Some interesting animals seen so far

Flying fish (they get spooked by the ship, take off and fly several yards low across the water!)
Cow-nosed Rays (see photo and caption below)
Leather-backed Sea-turtle (I’m used to seeing them on the beach in Trinidad—see my previous blog. It was a treat to see one swimming close by. I was even able to see the pink translucent spot on the head).
Bottle-nosed Dolphins
Seabirds (lots of them…. four lifers already—more on this later!)

school of cow-nose rays — We saw large schools of Cow-nosed Rays closer to the coast. These animals feed on bivalve mollusks like clams and oysters with their robust jaws adapted for such hard food. They are classified as Near Threatened due to their reliance on oyster beds which are themselves threatened by pollution and over exploitation.

Science and Technology Log

What an exciting first full day out at sea! I have been so grateful that our science team has allowed me to be completely hands-on and take responsibility for some of the science happening on the ship. In addition to checking the Imaging Flow Cytobot (IFCB) periodically, I am very much involved in the data collection at each of our stations.

There are specific stations along our course where scientists need to collect data. The crew announces when we are close to the station. At that time, along with another volunteer on watch, I don my foul weather gear to head out to the deck. We get pretty splashed as we are working with the equipment so the gear is a good idea. We help the crew as they lower “bongo nets” into the water using a cable and pulley system. Can you guess why they are called bongo nets? These nets have a very fine mesh that helps collect, you guessed it, PLANKTON!

bongos on deck — *bongo nets waiting on the deck to be deployed*

bongos in water — *The bongo net and the “baby” bongo net being deployed.*

We also help raise the bongo nets after several minutes dragging them through the water. We rinse all of the plankton down to the bottom of the net and then open up the end of the net to allow all of the plankton into a sieve where we will collect it. I have been surprised by the amount of jelly-like animals that have shown up in the nets!

Then it’s time to use special liquids (ethanol or formalin) and water to wash the plankton into collection jars. These chemicals will preserve the plankton so scientists can study it back in the lab!

It has been so much fun working with this equipment, asking the scientists questions about the plankton, and being a part of it all.

Harvey, our chief scientist, explained to me that many scientists can use the plankton samples for all different studies. Some of the samples can be used to study larval fish (baby fish) otoliths, the tiny ear bones that can verify the identification of larval hake using genetics. Knowing this, scientists can do research to determine where the larval fish were born! What a great example of the beginning of a scientific

Hake larvae — *Some examples of larval hake. Photo courtesy of Harvey Walsh*

experiment!:

Question – Where are most larval red hake fish born in the Northeast Atlantic Ocean?

Research – Scientists might research currents in the area, wind patterns, and other things that would push plankton from place to place. They also would research what other scientists have already learned about larval red hake.

Hypothesis – Most larval red hake fish are born in the Southern New England and Georges Bank regions in the northeast US shelf.

Didn’t I tell you plankton were amazing?

At some of the stations, we also lower Niskin bottles and CTD instruments into the water to collect a lot more data! More on that to come!

NOAA Corps Corner

Today I spoke with Lola Ajilore, Officer with NOAA Corps, and asked her a few questions about her important work. A pod of humpback whales off the bow stole the show! Here’s what we got in before the exciting interruption…

Me – Tell me more about your roles on the ship.

Lola – I am the Navigation Officer, Medical Officer, Environmental Officer, Ship Store Officer, and Morale Officer. As you can see, we all have multiple roles on the ship. As Navigation Officer, for example, I plot charts, track directions, and coordinate with the Operations Officer and Commanding Officer on track lines and routes that are requested by the scientists.

Me – Where do you do most of your work?

Lola – I am always with NOAA Ship Gordon Gunter. The ship’s home port is in Pascagoula, Mississippi. Our missions often take place in the Gulf of Mexico but we also run these Northeast Shelf cruises for Ecosystem Monitoring every year.

Me – What kind of training is needed for your line of work?

Lola – We undergo an application process that includes several interview steps. We then train at the Coast Guard Academy. Much of our training parallels that of the Coast Guard, but we also do our own NOAA Corps training as well.

Me – What tool do you use in your work that you could not live without?

Lola – Radar! [Radar aids navigation by detecting things that are far away such as an island or another ship]

I cannot believe the amazing views that we have on this ship 24 hrs. a day! The water has been super calm and the sunrise, sunset, breaching whales, and pods of dolphins have taken my breath away.

Yesterday was emergency drill day! Libby, our Operations Officer, had given us directions on how to respond to emergencies prior to leaving the

*Mustering on the deck during the emergency fire drill.*

dock. There are emergency drills for a fire (just like at school!), abandon ship (in the case that we had to immediately leave the ship in an emergency), and man overboard.

We practiced a fire drill and an abandon ship drill. The Officers on the ship sounded the alarm, using a different number and duration of blast based on the type of emergency. For a fire, we all “mustered” (got together in one place) in assigned areas. All of the science team members mustered together. For abandon ship, we all mustered near the life boats along with our life jackets and immersion suits (suits that can help you survive if you end up in the water).

Martha in immersion suit — *Here I am in my immersion suit!*

The fun part of the abandon ship drill was donning our immersion suits in one minute or less! This was a great thing to practice so if there ever was a real emergency, we would know how to put on the suit. I thought I looked pretty cool in my immersion suit.

Did You Know?

Salps are barrel-shaped planktonic tunicates. Our plankton bongo nets always contain some jelly-like salps. Where I live in the Florida Keys, we see mangrove tunicates growing on mangrove roots. Here in the open ocean, salps stick together in long colonies and drift! Sometimes there are so many salps in our nets, we have to filter them out with sieves and put them back in the water.

salps from web — *An example of a colony of salps. Photo courtesy of NOAA*

Something to Think About

We have been finding up to 4,000 phytoplankton in 5 mL of water. A gallon of water is equal to about 3785 mL. There is about 352,670,000,000,000,000,000 gallons of water in the Atlantic Ocean. How much plankton is in the Atlantic? You do the math.

Science and Technology Log

Tuesday, May 22, I arrived at Newport Naval Base and boarded NOAA Ship Henry B. Bigelow to begin my Teacher at Sea journey by staying overnight on a docked ship. Day 1 was filled with many new experiences as we headed out to sea. The Henry B. Bigelow is part of a fleet of vessels commissioned to conduct fishery surveys. To learn more about the Henry B. Bigelow, check out this website: Henry B. Bigelow. The objective of this cruise is to access the hydrographic, planktonic and pelagic components of North East U.S. continental shelf ecosystem. The majority of the surveys we will take involve the microbiotic parts of the sea – phytoplankton, zooplankton and mesoplankton. Plankton are small microscope organisms in the oceans that are extremely important to the entire Earth ecosystem. These organisms are the foundation of the entire ocean food web. By studying their populations. scientists can get an accurate picture of the state of larger ocean organism populations.

Before leaving the dock, I met with Emily Peacock from Woods Hole Oceanographic Institute (WHOI) to learn how to run an Imaging Flow Cytobot instrument that uses video and flow cytometric technology to capture images of phytoplankton. The IFCB was developed by Dr Heidi Sosik and Rob Olsen (WHOI) to get a better understanding of coastal plankton communities. The IFCB runs 24 hours a day collecting sea water and continuously measuring phytoplankton abundance. Five milliliters of sea water are analyzed every 20 minutes and produces the images shown below.

The science party on board is made up of scientists from National Marine Fisheries Service (NMFS) part of NOAA Fisheries Division. The chief scientist, Jerry Prezioso, works out of Narragansett Lab and the lead scientist, Tamara Holzworth Davis, is from the Woods Hole Lab, both from the NOAA Northeast Fisheries Science Center. Other members of the Science Party are Seabird/Marine Mammal observers and a student from Maine Maritime Academy. The Crew and scientist group work together to coordinate sampling stations. The crew gets the ship to the site and aid the scientists in deploying instruments. The scientists collect the data and samples at each station. The Crew and scientists work together to find the best and most efficient sea route to each sampling site. Note all the stops for specimen collection on map below. There definitely has to be a plan!

Because research instrument deployment is done 24 hours a day, the NOAA Corps crew and scientists are divided into two shifts. I am on watch 1200 – 2400 hours, considered the day shift. This schedule is working good for me. I finish duty at midnight, go to sleep till 9:00 AM and rise to be back on duty at noon. Not a bad schedule. Due to clear weather and calm seas, the ship headed east out of Newport Harbor towards the continental shelf and started collecting samples at planned stops. I joined another group of scientists observing bird and marine mammal populations from the flying bridge of the ship. Humpback whales and basking sharks breached several times during the day

It has only been two days but I feel very acclimated to life at sea. I am not seasick, thanks to calm seas and the patch. Finding the way around the ship is getting easier- it is like a maze. Spotting a pod of humpback whales breaching and basking sharks was a highlight of the day. My Biology students back at May River High School scored great on End of Course Exam. Congratulations May River High School Sharks! Thinking of y’all.

Love My SHARKS!
