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
Rinse sample bottle 3x
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.

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.

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’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.

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.

Science and Technology Log

The Long-Term Ecological Research (LTER) study focuses on ecosystem dynamics in the Northern Gulf of Alaska (NGA) and how the complex processes of abiotic factors, such as ocean salinity, temperature, currents, and trace metals influence primary productivity of phytoplankton. The project examines how efficiently this energy is transferred, in turn, to higher trophic levels, from zooplankton to vertebrates, such as fish, seabirds and marine mammals.

Over the past twenty years, seabird and marine mammal observations have been an important component of the LTER study. Approximately 50 species of birds inhabit the NGA either year-round or seasonally, with a variety of foraging behaviors and diets. Through the LTER, we can learn about how physical and biological oceanographic processes influence the distribution and abundance of higher trophic levels, such as seabirds.

Dr. Kathy Kuletz with the U.S. Fish and Wildlife Service (USFWS) is the lead scientist for the seabird part of the research program. Dan Cushing is the seabird and marine mammal observer aboard R/V Tiglax. He holds a master’s degree in wildlife science and has a wealth of experience in birding both on and offshore. This fall cruise marks Dan’s eleventh cruise observing in the NGA. Whenever the R/V Tiglax is underway, Dan can be found on the flying bridge collecting data.

Observations are made using a protocol established through the USFWS. Dan records survey data using a computer on the flying bridge that records both time and GPS coordinates of each bird or mammal sighting.

estimating distance — A chopstick with markings on it helps Dan estimate bird distance. Dan made this simple distance measuring tool using high-school trigonometry. When the top of the stick is placed on the horizon, the markings along the stick correspond to distances from the boat.

observing laptop — *Dan is able to quickly document the species seen, abundance and any special notes using the computer program.*

It is immediately clear that bird sightings along the LTER follow a pattern. Inshore, diving bird species are common, such as common murres, puffins and cormorants. Pelagic bird species inhabiting deeper waters are mostly surface-feeders, and rely on processes such as fronts and upwellings at the shelf break to concentrate prey at the surface where feeding occurs. Albatross, shearwaters and storm-petrels are abundant as we head further out on our sampling lines.

birds on the dock — *Pelagic cormorants and black-legged kittiwakes sit on the dock in Seward prior to our departure.*

Dan’s experience on the LTER study is helpful in that he can comment on both changes he sees from the spring, summer and fall cruises but also over the past several years. For example, in winter 2015-16, a large die-off event of common murres was observed in Alaska following an extreme warming event called “the blob” in the North Pacific. The murre die off was due to starvation from lack of forage fish availability. A question of the LTER study is how is the ocean chemistry, primary production, and zooplankton abundance tied to events such as this. Today, the murre numbers have not completely rebounded in the NGA and other species, such as the short-tailed shearwater are beginning to experience die-offs in the Bristol Bay area. In addition to shifts in bird populations, fish that frequent warmer waters, have been observed in the NGA, such as the ocean sunfish. Dan spotted one on this trip along our Middleton line swimming at the surface near a flock of albatross.

The fall survey is occurring when birds are preparing for harsh winter conditions or long migrations. We have spotted a few birds already changing to a winter plumage, which can make identification that much more challenging. As the strong September storms hit us, it is amazing to watch the birds handle the strong winds and driving rain. Last night as we worked on our nightly plankton tow a gale blew up around us. The winds picked up to 30 knots and the seas began to build to 10 feet, and the aptly named storm-petrels kept us entertained. At one point, we turned around and one had accidently gotten to close and seemingly stunned itself by hitting the back deck. We watched as it shook off the confusion and again took flight into the storm.

*A fork-tailed storm petrel. Photo credit: Dan Cushing*

One of the exciting things about Dan’s job and my time observing with him was the sightings of rare and endangered species. Just off of Cape Cleare, as I sat on the flying bridge with Dan, I heard him exclaim, “no way!” as he grabbed his camera for some shots. After a few quiet moments, he shared that he had officially has his first sighting a Manx shearwater. The Manx shearwater has a primary range in the Atlantic Ocean, with rare but regular (1-2 per year) sightings in the NGA. There currently are no confirmed breeding locations identified in the Pacific Ocean. Every new sighting adds to our limited understanding of this small and mysterious population. Another exciting observation, although more frequent for Dan, was the short-tailed albatross. This beautiful bird, with its bubble-gum pink bill, is currently critically endangered, with a global population of only about 4000. The good news is that the population is currently rebounding from extremely low numbers.

Dan has not only done an amazing job as an observer but also as a teacher. He has helped me identify the birds as we see them and given me tips on how to hone in on particular species. In addition to this, he has supplied me with amazing facts about so many of the species, I am in awe of his knowledge, patience and his skill as a seabird and mammal observer.

Personal Log

One of the biggest questions I had (as well as my students) prior to my trip, was how would I handle sea sickness. I must say for a person who used to get sea sick snorkeling, I am thrilled to announce that I am sea sickness free. After riding through three strong gales with 12+ seas and 35-40 knot winds without any major problems, I think I’m in the clear. I owe a lot of it to consistent Bonine consumption!

Additionally, I would say I officially have my sea legs on. I have gotten really good at working, walking, eating, typing, and my brushing my teeth in high seas as the boat tosses about. One of my favorite phrases is when Captain John says, “the seas are going to get a bit snappy.” I asked him what he meant by this and he explained that snappy means the waves are sharp and about 8-12 feet in height in contrast to the swells. They hit the ship with a snap that causes it to vibrate, rather than just allowing it to slowly roll over them.

A last thing that has surprised me on this trip so far is the warm weather. I am typically always cold and was worried about how I would manage working outside on the nightshift in the elements. The weather, despite intermittent storms has remained surprisingly warm and with our mustang suits and rain gear, we have remained mostly dry. Almost daily we have had the pleasure of a beautiful ocean sunset, a full moon rising and stars over our heads. Now we are just crossing our fingers for some northern lights to grace our presence.

Science and Technology Log

We’ve had a flurry of whale sightings as we passed over the famous Stellwagen Bank National Marine Sanctuary. It’s a small underwater plateau in Massachusetts Bay flanked by steep drop offs. Nutrients from the depths rise up by upwelling along the sides, feeding phytoplankton in the shallow light-abundant waters, and this creates perfect feeding habitat for whales.

Much of my time aboard this ship has been on the flying bridge (the highest point of access for us on the ship) scanning the seas for marine vertebrates. I have basically been an extra pair of eyes to assist my colleagues Chris Vogel and Allison Black, the seabird observers on board. From nearly 50 feet high above the water, the flying bridge gives nearly unimpeded 360° views of the horizon all around. I call out any vertebrate animal seen—fish, birds, reptiles, or mammals. Chris and Allison enter all of our data in a specific format in a software program called SeaScribe.

To calculate densities of each species, we need an estimate of how far the animal is from the ship for each sighting. For that we use a rather low tech but effective piece of equipment. The pencil!

This is how it works. The observer holds the pencil (photo above) upright with arm outstretched, aligning the eyes and tip of the eraser to the horizon (see photo below), and simply reads the distance band (Beyond 300m, 300-200, 200-100, or 100-50m) in which the animal is seen. Thanks to some fancy trigonometry, scientists found a way to estimate distance by using the height of the observer’s eyes from the water surface, the distance from the observer’s eyes to the eraser tip of the pencil when it’s held upright with arm outstretched, and the distance to the horizon from the height of observer’s eyes above water. I’ll spare you the trigonometric details but those curious to learn more can find the paper that introduced the technique here.

Seabirds are a challenge for a rain forest biologist like me. They move fast and vanish by the time you focus the binoculars! And the fact that the deck heaves up and down unexpectedly adds to the challenge. But slowly I got the hang of it, at least the very basics. I’ve recorded hundreds of shearwaters, storm-petrels, boobies, gannets, jaegers, and skuas. Whales (sea mammals) seen include Finbacks, Humpbacks, Minkes, and Pilots. I am hoping to see a Right Whale but I know that the odds are against me. Time is running out, both for our voyage, and for them. Unfortunately, only a few 100 are left and the ocean is huge—the proverbial needle in the haystack. Chief Scientist Harvey Walsh tells me that this year so far, 8 Right Whales have died due to accidental collisions or net entanglements. Sadly, the future looks bleak for this magnificent animal. (More on Right Whales at the end of this blog).

I note that marine vertebrate biologists are good at extrapolating what little they can see. Much of their subjects are underwater and out of sight. So they have become good at identifying species based on bits and pieces they see above water. All they need often is a mere fleeting glimpse. Sharks are told by the size, shape, and distance between the fins that stick out, sea turtles by the shape and pattern on their carapace (top shell–see photos below); whales based on their silhouette and shape of back; and Molas based simply on the fact that they lazily wave one large fin in and out of the water as they drift by. (I thought it was the pectoral fin they waved, but it’s actually the massive dorsal fin. I’ve noted that the pectoral is rather small and kept folded close to the body).

shark fins — We’ve had several shark sightings such as this. The size, shape, and the relative locations of the fins indicate that this could be a whale shark (Photo by Allison Black)

Scientists can identify individual humpbacks based solely on the indentations and color patterns on their tail flukes. In effect, each individual animal’s tail fluke is its unique fingerprint. Since the tail fluke is often seen when the animal dives from the surface, scientists have a huge photographic database of humpback tail flukes (see photo below). And they track individuals based on this. My ecology students should know that scientists also estimate populations based on a modification of the capture-recapture method because each time an individual’s fluke is photographed, it is in effect, “tagged”. We do a nice lab exercise of this method by using marked lima beans masquerading as whales in my ecology lab.

Career Corner

I spoke with Allison Black, one of our seabird observers on board.

Q. Tell us something about yourself

A. I really love seabirds. I’m fortunate to have been able to do my Master’s work on them and observe them in their natural habitat. I have an undergrad degree in zoo and wildlife biology from Malone University in Canton, Ohio.

Q. You’re a graduate student now in which university?

A. Central Connecticut State University

Q. What’s your research project?

A. I conducted a diet study of Great Black-backed and Herring Gulls on Tuckernuck and Muskeget Islands, Massachusetts.

Q. You have done these NOAA seabirds surveys before?

A. Yes, this is my third.

Q. What happens next, now that you are close to finishing your Masters?

A. I’m looking for full time employment, and would like to work for a non-profit doing conservation work. But until the right opportunity arises you can find me on a ship, looking for seabirds and marine mammals!

Q. What’s your advice to anyone interested in marine science?

A. I had a major career change after I did my undergrad. I thought I’d always be a zoo keeper, which I did for about two years until I decided that birds are really my passion, and I needed to explore the career possibilities with them. To focus on that avenue I decided to return to graduate school. So I would encourage undergrads to really find what drives them, what they’re really passionate about. I know it’s hard at the undergraduate level since there are so many fields and avenues under the Biology umbrella. And it’s OK if you haven’t figured that out for a while. I had a real change in direction from captive wildlife to ornithology, and I’m here at sea in a very different environment. I’m so glad I did though because following my passion has opened up some exciting avenues. I’m lucky to be getting paid to do what I really love right now. So grab any opportunity that comes by. It’s never too late to evaluate your career path.

Personal Log

My feelings are bitter-sweet as this wonderful 16-day voyage nears its end. My big thanks to NOAA, the ship’s wonderful command officers and staff, our Chief Scientist Harvey Walsh, and my colleagues and student volunteers aboard for making the past 2 weeks immensely absorbing. Above all, kudos to the ship’s designers, who have clearly gone out of their way to make life aboard as easy as possible. In addition to the unexpected luxuries covered in my previous blogs, there is even a movie lounge on board with an impressive DVD collection of over 700 movies! Yesterday I saw our student volunteers play bean bag toss on the winch deck. Yes, you can throw darts too. The ship’s command even organized a fun sea animals-bingo game one evening, with winners getting goodies from the ship store (see below).

The engine rooms tour

As part of our grand finale, we were given a tour of the engine rooms (which are usually off bounds for non-crew members) by our genial First Engineer, Kyle Fredricks.

Through the Microscope

Gwenn with microscope — Gwenn using one of the microscopes to look at phytoplankton.

Gwenn and labels — The Lady of a Thousand Labels, hard at work.

Dr. Gwenn Hennon will be starting as an Assistant Professor with the University of Alaska in the fall. Her interest is in the types of microbes, especially phytoplankton, that are in the water and what they are doing. She is studying what limits them, whether it is nutrients, light or other factors. She finds it interesting to try to find interactions between phytoplankton and other organisms, such as ciliates that are filled with chloroplasts that they steal, termed “kleptoplasts.” She investigates what microbes they stole them from, how the ciliate steals the plastid and how they maintain it. While a lot of algae have photosynthetic genes and controls in the nucleus, ciliates wouldn’t be expected to have those controls, but they must have some in order to keep plastids alive, and these need to have specific genes in order to control specific plastids. There is a trade-off between specificity of genes for certain plastids and being able to keep the plastids alive for a long time. Ciliates can also live by just eating other organisms, so another field of investigation would be to look at which genetics are used when organisms are switching between strategies. One goal of this research would be that, when looking at samples from various stations, someone would be able to say what the ciliates are doing without having to do experiments.

The NGA is a very complex ecosystem, and this cruise has shown me that any scientific investigation needs to have a very specific focus rather than a shotgun approach, in order to have productive results. There is so much to be studied that the potential amount of data that can be gathered is staggering.

Because the LTER has been funded for many years, there are great sets of time series to look at for some studies, but molecular data is fairly new and adds a lot to the picture. Gwenn’s work, and the work of others at the molecular level are just the beginning of an understanding of life at the microscopic end of the scale.

Through the Binoculars:

Fin whales come fairly close to us out in the deeper Gulf waters.

Dan Cushing is the U.S. Fish and Wildlife seabird and mammal specialist and is here to investigate organisms at the large end of the size spectrum, compared to everyone else on board. His workstation is primarily the bridge of the ship, where he is on the lookout for birds and mammals. He records the species and number spotted, and the time and the GPS location of each sighting. He also logs environmental conditions such as fog and wave height that can affect visibility.

Dan comes from a small fishing town with a population of 3000. He wasn’t necessarily interested in birds specifically when he was young, but developed a gradual interest in them. He likes that working with seabirds combines aspects of being a wildlife biologist with aspects of being a marine biologist. Dan has done both land-based projects at seabird breeding sites and ocean-based surveys on small boats and large research ships. One project that he worked on included attaching sensors to diving birds to record water temperature, depth, and location. This provided information about water conditions as well as about the behaviors of the birds and their feeding patterns in those conditions.

The variation in distribution and feeding strategies of bird species make them a good indicator of what is happening to the environment at different levels in the ecosystem. For example, Dan used small-boat surveys to look at changes in marine bird populations in Prince William Sound. He found that, over a period of two decades, declines had occurred in almost half of the species he looked at. In general, species that occurred farther from shore and fed on zooplankton and fish had greater declines than those that fed on prey along the shoreline and the nearby seafloor.

Studying the changes in a bird population leads to investigations that connect down the food chain through fish species to plankton (which, of course, is the focus of this cruise) and finally to climate change. Dan sees changes in the availability of fish species having a direct effect on the economic health of Alaskan communities that depend on fishing to survive. Coming from a fishing community, this hits home for him. As smaller species respond to climate change, a ripple effect works its way up the food web and so human populations must also alter their survival strategies as well.

Personal Log:

The longer I’m on board, the more the pieces of the puzzle seem to come together. On thing that really strikes me about the teams on board is the intensity of their research and the drive they have. Each person here is making the most of their opportunity for data gathering. Gwenn, for instance, I have nicknamed “the lady of a thousand labels” because her work ethic and preparedness are so impeccable. She is just one example of the discipline and passion I see on board.

There is enough potential data to be gathered here to provide for years of research. Each of these researchers is not only singularly focused on their specialty but also well aware of the underlying premise of their research, i.e. that what they’re studying will serve to document climate change. Already, this year has brought anomalous weather to the Gulf, which, in a sense, makes conclusions about how and why changes occur a bit difficult. Another thing that is noteworthy on this cruise is that, because there are PIs (Principal Investigators) on board, there is a lot of discussion of ideas and plans for collaboration. Already, Gwenn, Suzanne, Hana and Clay have been talking about a potential project where their ideas intersect. The amount of time we’re out allows for more interaction between people and more room for ideas to develop.

Finally, as I ask each person what they want kids or the public to know from their research, the answers I am getting all focus on the same thing: change is happening and every organism on the planet is affected by it.

map of the shelf — An image of the shelf; the data station lines cross over this to get a complete range of samples from shallow to deep in order to understand the complexity of the ecosystem and the changes happening within it.

What do you want kids to know about your research?

Gwenn: All things are related to each other. All species on earth developed from the same ancestral single-celled organisms.

Dan: If you don’t pay attention to what’s around you, you won’t see how it changes.
