One of my favorite parts about working as a member of the GEMM lab is our monthly lab meeting. It’s a chance for everyone to share exciting news or updates about their research, discuss recent advances in our field, and of course, make the schedule for who is in charge of writing the blog each week! Our fearless leader, Leigh, usually also has an exercise for us to complete. These have varied from writing and editing abstracts for conferences, conducting mock interviews of each other, reading and discussing relevant papers, R coding exercises, and other useful skills. Our most recent meeting featured an exciting announcement, as well as a really interesting discussion of the latest International Whaling Commission (IWC) reports of the scientific committee (SC) that I felt might be interesting to share with our readers.
First, the good news – Six GEMM lab members submitted abstracts to the 2017 Society of Marine Mammalogy Conference, and all six were accepted for either a speed talk or an oral presentation! We are very proud and excited to present our research and support each other at the conference in October.
And now, a little science history:
The IWC was originally formed as a management body, to regulate the global catch of great whales. However, it never had much legal power to enforce its edicts, and was largely ineffective in its task. By 1986 whale populations had been decimated to such low numbers by commercial whaling efforts that a worldwide moratorium on harvest was imposed. The SC of the IWC meets on an annual basis, and is made up of leading experts in the field who give advice and recommendations to the commission. If you are interested in seeing reports from over the years, follow this link to the IWC Archive. The reports presented by the various sub committees of the Scientific Committee are dense, packed full of interesting information, but also contain lots of procedural minutiae. Therefore, for this lab meeting, each of us took one of the 2017 Annexes, and summarized it for the group.
Alyssa and Dawn reviewed Annex J: Report of the working group on non-deliberate human induced mortality of cetaceans. The report shared new data about scarring rates of bowhead whales in the Bering Sea, notably, that 2.4% of the population will acquire a new scar each year, and that by the time an individual is 25 years old, it has a 40% chance of being scarred from a human derived interaction. The study noted that advances in drone technology may be an effective tool to assess scarring rates in whale populations, but emphasized that it is important to examine stranded carcasses to ground truth the rates we are able to capture from aerial and boat based photography. The discussion then turned to the section about ship strikes, where we learned that in a comparison of fresh scars on humpback whales, and rates of voluntarily reported ship strikes, collisions were vastly under reported. Here it was noted that injuries that did not cause visible trauma could still be lethal to cetaceans, and that even moderate speed collisions can cause non-immediate lethal injury.
Leila walked us through Annex K: Report of the standing working group on environmental concerns. This subcommittee was the first one formed by the SC, and their report touched on issues such as bioaccumulation of heavy metals in whales, global oil spill emergency response training, harmful algal blooms (HABs), marine debris, diseases of concern, strandings and related mortality, noise, climate change, loss of arctic sea ice, and models of cetacean reaction to these impacts.
A few notes of particular interest:
-PCBs and other toxins are known to accumulate in killer whales, but this report discussed high levels of lead and cadmium in gray whales, leading to the question of what might be the source – sediment deposits? Fish?
-Lots of research has been done on the outfall of HABs involving domoic acid; now there is a need for research on other types of HABs
-A website has been created to increase surveillance, diagnosis and risk management of cetacean diseases, and is currently being refined: https://cdoc.iwc.int
-Changing climate is prompting distribution shifts in a number of species, putting animals at risk of interactions with shipping lanes, and increasing contact with invasive species.
-Models of cetacean bioenergetics have found that being entangled has energy costs equivalent to migration or pregnancy. Another model found that naval noise increased the metabolic rate of individuals by 30%. Models are becoming more and more accurate and complex every year, and each new one helps provide a framework to begin to assess cumulative impacts of human-cetacean interactions.
To wrap things up, I gave a brief overview of Annex N: Report of the subcommittee on whalewatching. This report gave quick updates on a number of different whale watching research projects around the world:
-Humpback whales in Hawaii change their swim speed and dive time when they encounter vessels.
-Endangered humpbacks in the Arabian Sea may need management intervention because there have been minimal advances in standards and attitudes by whale watching outfits or recreational boaters in Oman.
-Increased interactions and close encounters may be eroding the protective social barriers between bottlenose dolphins and the public. The committee emphasizes that cetacean habituation to humans is a serious conservation cause of concern.
After research updates, the document then details a review from the working group on swim-with-whale operations. They emphasize the need for a global database, and note that the Convention on Migratory Species and the World Cetacean Alliance are both conducting reviews of this section of the whale watching industry and that a collaboration could be beneficial. Finally, this committee often gives feedback to ongoing projects and local management efforts, but is not convinced that their recommendations are being put into practice.
As one reads this litany of issues that face cetaceans in the modern world, it can be quite disheartening. However, reports like these keep researchers up to date on the current state of knowledge, areas of concern, and questions that need answering. They help us set our priorities and determine which piece of the puzzle we are capable of tackling. For more on some of the projects that our lab has under taken to help tackle these issues, check out Leila’s work on stress in gray whales, Dawn’s work looking at blue whales in New Zealand, Solene’s work on humpback habitat selection, or my work on vessel interactions. Individually, it’s easy to feel small, but when you look through the archives of the IWC, and realize how far we’ve come from extractive management to active conservation, you realize that every little project adds to those before it, and together, we can make a difference.

Prepping for fieldwork is always a complex mental and physical juggling act, especially for an equipment-rich, multi-disciplinary, collaborative project like our research project on the impacts of ocean noise on gray whale physiology. For me, the past couple months has consisted of remembering to coordinate equipment purchasing/testing/updating (cameras, drones, GoPros), obtaining all needed permits/licenses (NMFS, FAA, vessel), prepping data recording and management protocols (data sheets, dropbox), scheduling personnel (7 people over 5 months), organizing sampling gear (fecal nets, zooplankton traps), gathering all needed lab supplies (jars, filters, tubes), and hoping for good weather.
This list would normally be enough to overwhelm me, but this year we have also had the (fortunate) opportunity to outfit our own research vessel. The OSU Marine Mammal Institute (MMI) obtained a surplus 5.4 m coast guard RHIB (rigid inflatable haul boat) and generously handed it off to the GEMM Lab for our coastal Oregon research. Fantastic! But not perfect, of course. What the coast guard needs as a vessel, is not exactly what we need for whale research. When the vessel arrived it had a straddle seat occupying most of the limited interior space, which would make it very hard for three people to ride comfortably during a long day of survey effort or move around during whale sightings.
So, the boat needed a re-fit. And who better to do this re-fit than someone who has spent more than 15 years conducting whale research in a RHIB, is a certified ABYC marine electrician, and runs his own marine repair business? Who has such a qualified resume? My research technician (and husband), Todd Chandler.
Over the last two months Todd has meticulously rearranged the interior of the vessel to maximize the space, prioritize safety and comfort, balance the boat for stability, and allow for effective data collection. He removed the straddle seat, had a light-weight aluminum center console and leaning post built to just the right size and specs, installed and updated electronics (VHF, GPS chart plotter), re-ran the engine wiring (throttle, tilt, kill-switch), patched up a few (8!) leaks in the pontoons, ran new nav lights, installed new fuel tanks, and serviced the engine. Phew! He did an amazing job and really demonstrated his skills, handiwork, and knowledge of field research.
The vessel now looks great, runs smoothly, and gives us the space needed for our work. But, she needed a name! So, on Saturday afternoon we hosted a GEMM Lab boat naming BBQ. Our research team and lab gathered in the sun to admire the vessel, eat good food, watch the kids run and play, and come up with boat names.
I was impressed by the appropriate, thoughtful, clever names put forth, like Adam’s rib, Cetacea, Oppo (re-arrange poop), and Whale Done. I was faced with a tough decision so I made everyone vote; three ticks each.
And the winner is…… Ruby: An appropriate name for a research vessel in the GEMM Lab. Perhaps someday we will have a fleet: Ruby, Emerald, Diamond… Ah, a girl can dream.
Now it’s time for the many hiccups, challenges, and rewards of a field season. So thanks to Todd, the MMI, the GEMM Lab, and our awesome team for getting us ready to go. Stay tuned for updates on the actual research (and how Ruby performs).

Earth day is a worldwide event celebrated annually on April 22, and is typically observed with beach, park, or neighborhood clean ups, and outreach events sponsored by environmental groups. Last year, environmentalists rejoiced when 195 nations signed the Paris Agreement – to “strengthen global response to the threat of climate change by keeping global temperature rise below 2 degrees C”.
This year, the enviro-political mood is more somber. Emotions in the GEMM Lab swing between anger and dismay to cautious optimism and hope. The anger comes from threatened budget cuts, the dismissal of climate science, and the restructuring of government agencies, while we find hope at the outpouring of support from our local communities, and the energy building behind the March for Science movement.
What is perhaps most striking about the movement is how celebratory it feels. Instead of marching against something, we are marching FOR science, in all its myriad forms. With clever signs and chants like “The oceans are rising, and so are we”, “Science, not Silence”, and “We’re nerds, we’re wet, we’re really quite upset” (it rained on a lot of marches on Saturday) echoing around the globe, Saturday’s Marches for Science were a cathartic release of energy, a celebration of like-minded people.
While millions of enthusiastic people were marching through the streets, I “Ran for Science” at the 20th annual National Ocean Science Bowl (NOSB) – delivering question sheets and scores between competitors and graders as 25 teams competed for the title of national champion! Over the course of the competition, teams of four high school students compete through rounds of buzzer-style multiple choice questions, worksheet style team challenge questions, and the Scientific Expert Briefing, a mock congressional hearing where students present science recommendations on a piece of legislation. The challenges are unified with a yearly theme, which in 2017 was Blue Energy: powering the planet with our ocean. Watching the students (representing 33 states!) compete is exciting and inspiring, because they obviously know the material, and are passionate about the subject matter. Even more encouraging though, is realizing that not all of them plan to look for jobs as research scientists. Some express interest in the arts, some in policy, or teaching or engineering. This competition is not just about fostering the next generation of leading marine scientists, but rather about creating an ocean-literate, and scientifically-literate populace. So, congratulations to Santa Monica High School, who took home the national title for the first time this year! Would you like to test your knowledge against some of the questions they faced? Try your luck here!
The GEMM Lab also recently participated in the Hatfield Marine Science Center’s Marine Science Day. It’s an annual open house where the community is invited to come tour labs, meet scientists, get behind the scenes, and learn about all the exciting research going on. For us as researchers, it’s a great day to practice explaining our work and its relevance to many different groups, from school children to parents and grandparents, from artists to fishermen to teachers, fellow researchers, and many others. This year the event attracted over 2,000 people, and the GEMM Lab was proud to be a part of this uniquely interactive day. Outreach events like this help us feel connected to our community and the excitement present in all the questions field during this event reassure us that the public still cares about the work that we do.
Our science is interdisciplinary, and we recognize the strength of multiple complimentary avenues of action to affect change. If you are looking to get involved, consider taking a look at these groups:
500 Women Scientists: “working to promote a diverse and inclusive scientific community that brings progressive science-based solutions to local and global challenges.” Read their take on the March for Science.
314Action: starting from Pi (3.14), their mission is “to (1) strengthen communication among the STEM community, the public and our elected officials, (2) Educate and advocate for and defend the integrity of science and its use, (3) Provide a voice for the STEM community on social issues, (4) Promote the responsible use of data driven fact based approaches in public policy and (5) Increase public engagement with the STEM Community through media.”
She should run: “A movement working to create a culture that inspires women and girls to aspire towards public leadership. We believe that women of all backgrounds should have an equal shot at elected leadership and that our country will benefit from having a government with varied perspectives and experiences.” https://peoplesclimate.org/
And finally, The March for Science is finishing up it’s week of action, culminating in the People’s Climate March on April 29.
How will you carry the cause of science forward?

40 years ago, in 1977 OSU researchers led an NSF funded expedition to the Galapagos on a hunt for suspected hydrothermal vents. From the 1960s to the mid-1970s, mounting evidence such as (1) temperature anomalies found deep in the water column, (2) conduction heat flow probes at mid ocean ridges recording temperatures much lower than expected, (3) unusual mounds found on benthic mapping surveys, and (4) frequent, small, localized earthquakes at mid oceanic ridges, had the oceanographic community suspecting the existence of deep sea hydrothermal vents. However, until the 1977 cruise, no one had conclusive evidence that they existed. During the discovery cruise at the Galapagos rift, the PI (principle investigator), Dr. Jack Corliss from OSU, used tow-yos (a technique where you drag a CTD up and down through the water in a zig zag pattern – see gif) to pinpoint the location of the hydrothermal vent plume. 
The team then sent the Deep Submergence Vehicle (DSV) Alvin to investigate and returned with the first photographs and samples from a hydrothermal vent. While discovery of the vent systems helped answer many questions about chemical and heat fluxes in the deep sea, it generated so many new questions that novel fields of study were created in biology, microbiology, marine chemistry, marine geology, planetary science, astrobiology and the study of the origin of life.
“Literally every organism that came up was something that was unknown to science up until that time. It made it terribly exciting. Anything that came [up] on that basket was a new discovery,” – Dr. Richard Lutz (Rutgers University)
In celebration of this great discovery, OSU’s College of Earth, Ocean and Atmospheric Sciences sponsored a seminar looking at the past, present, and future of hydrothermal vent sciences. Dr. Robert Collier began with a timeline of how the search for hydrothermal vents began, and a commemoration of all the excellent researchers and collaborations between institutions and agencies that made the discovery possible. He acknowledged that such collaborations are often somewhat tense in terms of who gets credit for which discovery, and that while Oregon State University was the lead of the project, it takes a team to get the work done. Dr. Jack Corliss proudly followed up with a wonderful rambling explanation of how vent systems work, and a brief dip into his ground breaking paper, “An Hypothesis concerning the relationship between submarine hot springs and the origin of life on Earth.” Published in 1981, with co-authors Dr. John Baross and Dr. Sarah Hoffman, they postulate that the temperature and chemical gradients seen at hydrothermal vents provide pathways for the synthesis of chemical compounds, formation and evolution of ‘precells’ and eventually, the evolution of free living organisms.
Because of time constraints, the podium was swiftly handed over to Dr. Bill Chadwick (NOAA PMEL/ HMSC CIMRS) who brought us forward to the present day with an exciting overview of current vent research. He began by saying “at the beginning, we thought, ‘No one has seen one of these systems before, they must be very rare…’ Now, we have found them [hydrothermal vents] in every ocean basin – including the arctic and southern oceans. We just needed to know how to look!” Dr. Chadwick also reminded us that even 40 years later, new discoveries are still being made. For example, on his most recent cruise aboard the R/V Falkor in December 2016, they found a sulfur chimney that was alternately releasing bubbles of gas (sulfur, CO2 or other, hard to know without sampling) or bubbles of liquid sulfur! Check out the video below:
Some of the goals for this recent cruise included mapping new areas of the Mariana back-arc, and investigating differences in the biological communities between vents in the Mariana trench region (a subduction zone) and vents in the back arc (a spreading zone) to see if geology plays a role in biological community composition. For some very cool video footage of the expedition and the various dives performed by the brand new ROV SUBastian (because all scientists love puns), check out the Schmidt Ocean Institute youtube channel.
Dr. Chadwick showed this video to highlight results from his last cruise.
Finally, Dr. Andrew Thurber wrapped up the session with some thoughts about hydrothermal vents from the perspective of an ecosystem services model. Even after 40 years of research, there are still many unknowns about these ecosystems. Individual vent systems are inherently unique due to their deep sea isolation. However, most explored sites have revealed metals and mineral deposits that have generated a lot of interest from commercial sea floor mining companies. Exploitation of these deposits would be an example of ecosystem “provisioning services” (products that are obtained from the ecosystem). Other examples include the biology of the vents as a source of new genetic material, and the thermal and chemical gradients as natural laboratories that could lead to breakthroughs in pharmaceutical research. Cultural services are those non-material benefits that people obtain from an ecosystem. At hydrothermal vents these include new scientific discoveries, educational uses (British children’s television show “The Octonauts,” has several episodes featuring hydrothermal vent creatures), and creative inspiration for artists and others. Dr. Thurber cautions that there are ethical questions to be answered before considering exploitation of these resources, but there is a lot of potential for commercial and non-commercial use of vent ecosystems.
As an undergraduate at the University of Washington, I spent time as a research assistant in Dr. John Baross’ astrobiology lab. We studied evolutionary pathways of hydrothermal vent viruses and bacteria to inform the search for life on exoplanets such as Jupiter’s moon Europa. It was very fun and exciting for me to attend this seminar, hear stories from pioneers in the field, and remember the systems I worked on in undergrad. I may have moved up the food chain a little now, but as we all work on our pieces of the puzzle, it is important for scientists to remember the interdisciplinary nature of our work, and how there is always something more to learn.

8:35pm on February 20th found the blue whale team smiling, singing, and dancing on the aft deck of the R/V Star Keys as the light faded and the sky glowed orange and we marked our final waypoint of the 2017 blue whale field season. What preceded was a series of days so near perfect that we had barely dared dream of the like. Sighting after sighting, and our team of scientists and the wonderful Star Keys crew began to work like a well-oiled machine—approach the whale gently and observe its behavior, fly the drone, deploy the CTD and echosounder, approach for photos, launch the small boat, approach for biopsy, leave the whale, re-apply sunscreen, find another whale, repeat. This series of events continued from sunrise until sunset, when the sky and water were painted brilliant colors. The sound of big blue whale breaths broke the silence over the glassy water, and the plumes of exhaled air lit up in the last bits of sunlight, lingering there without even a puff of wind to blow them away.
Despite coming to New Zealand during the “worst summer ever”, I’m pleased to say that this has been the most fruitful field season the New Zealand blue whale project has had. We covered a total of 1,635 nautical miles and recorded sightings of 68 blue whales, in addition to sightings of killer whales, pilot whales, common dolphins, dusky dolphins, sharks, and many seabirds. Five of our blue whale sightings included calves, reiterating that the South Taranaki Bight appears to be an important area for mother-calf pairs. Callum and Mike (Department of Conservation) collected 23 blue whale biopsy samples, more than twice the number collected last year. Todd flew the drone over 35 whales, observing and documenting behaviors and collecting aerial imagery for photogrammetry. We took 9,742 photos, which will be used to determine how many unique individuals we saw and how many of them have been sighted in previous years.
It is always hard to see a wonderful thing come to an end, and we agreed that we would all happily continue this work for much longer if funding and weather permitted. But as the small skiff returned to the Star Keys with our final biopsy sample and the dancing began, we all agreed that we couldn’t have asked for a better note to end on. There has already been plenty of wishful chatter about future field efforts, but in the meantime we’re still floating from this year’s success. I will certainly have my hands full when I return to Oregon, and in the best possible way. It feels good to have an abundance of data from a project I’m passionate about.
Thank you to Western Work Boats and Captain James “Razzle-Dazzle” Dalzell, Spock, and Jason of the R/V Star Keys for their hard work, patience, and good attitudes. James made it clear at the beginning of the trip that this was to be our best year ever, and it was nothing less. The crew went from never having seen a blue whale before the trip to being experts in maneuvering around whales, oceanographic data collection, and whale poop-scooping. Thank you to Callum Lilley and Mike Ogle from the Department of Conservation for their time, impressive marksmanship, and enthusiasm. And once again thank you to all of our colleagues, funders, and supporters—this project is made possible by collaboration. Now that we’ve wrapped up, blue whale team members are heading in different directions for the time being. We’ll be dreaming of blue whales for weeks to come, and looking forward to the next time our paths cross.
Join us for a couple boat rides as we study blue whales in the South Taranaki Bight of New Zealand.
In both videos below you can see and hear the field team coordinate to capture photo-identification images of the whale(s) while also obtaining a small tissue biopsy sample. It is important to match the individual whale to the sample so we can link biological data obtained from the sample (genetics, hormones, stable isotopes) to the individual whale. We also carefully take notes on where, when and what we collect in order to help us keep track of our data.
In this video clip you can watch as we gently approach two blues surfacing off the starboard bow of the RV Star Keys in order to capture photo-identification images and a small tissue biopsy sample. Callum Lilley (DOC) on the bow; Leigh Torres, Dawn Barlow, and Todd Chandler (OSU) photographing and coordinating from the flying bridge.
We are in the small boat here collecting data on a pair of blue whales. Callum Lilley (DOC) is on the rifle; Leigh Torres (OSU) is on the camera and taking notes; Todd Chandler (OSU) is on the helm.

After four full-on days at sea covering 873 nautical miles, we are back in port as the winds begin to howl again and I now sip my coffee with a much appreciated still horizon. Our dedicated team worked the available weather windows hard and it paid off with more great absence data and excellent presence data too: blue whales, killer whales, common dolphins, and happily swimming pilot whales not headed to nearby Farewell Spit where a sad, massive stranding has occurred. It has been an exhausting, exhilarating, frustrating, exciting, and fulfilling time. As I reflect on all this work and reward, I can’t help but feel gratified for our persistent and focused planning that made it happen successfully. So, as we clean-up, organize data, process samples, and sit in port for a few days I would like to share some of our highlights over the past four days. I hope you enjoy them as much as we did.

“This is the worst summer ever in New Zealand.” During our four days of prep in Wellington before heading off on our vessel, almost all my friends and colleagues I spoke to said this statement (often with added emphasis). It’s been cold and windy here all summer long, and when the weather has cleared it has brought only brief respite. These comments don’t bode well for our blue whale survey dependent on calm survey conditions, but February is typically the prime month for good weather in New Zealand so I’m holding out hope. And this unpredictable weather is the common denominator of all field work. Despite months (years?) of preparation, with minute attention to all sort of details (e.g., poop net handle length, bag size limits, length of deployment lines), one of the most important factors to success is something we have absolutely no control over: the weather.
After just one day on the water, I can see that the oceanographic conditions this year are nothing like the hot-water El Niño conditions we experienced last summer. Surface water temperatures today ranged between 12.8 and 13.6 ⁰C. These temps are 10 degrees (Celsius) cooler than the 22 ⁰C water we often surveyed last summer. 10 degrees! Additionally, the current windy conditions have stirred up the upper portion of the ocean water column causing the productive mixed layer to be much deeper (therefore larger) than last year. While Kiwis may complain about the ‘terrible’ weather this summer, the resulting cold and productive oceanographic conditions are likely preferable for the whales. But where are the whales and can we find them with all this wind?
Today we had a pocket of calm conditions so our dedicated research team and crew hit it with enthusiasm, and collected a whole lot of great absence data. “Absence data?” you may ask. Absence data is all the information about where the whales are not, and is just as important as presence data (information about where the whales are) because it’s the comparison between the two sets of data (Presence vs Absence) that allows us to describe an animal’s “habitat use patterns”. Today we surveyed a small portion of the South Taranaki Bight for blue whales for about 6 hours, but the only blue animals we saw were little blue penguins and a blue shark (plus fur seals, dolphins, albatrosses, shearwaters, gannets, prions, kahawai, and saury). But during this survey effort we collected a lot of synoptic environmental data to describe these habitats, including continuous depth and temperature data along our track, nine CTD water column profiles of temperature, salinity and florescence (productivity) from the surface to the seafloor, and continuous prey (zooplankton) availability data with our transducer (echosounder).
So, now that we have absence data, we need presence data. But, the winds are howling again and are predicted to continue for the next few days. As we hunker down in a beautiful protected cove I know the blue whales continue to search this region for dense food patches, unencumbered by human-perceived obstacles of high wind and swell. So, while my Kiwi friends are right – this summer is not like previous years – I also know that it is the effects of these dynamic weather patterns that we have come so far, and worked so hard, to study. Even as my patience wears thin and my frustrations mount, I will continue to wait to pounce on the right weather window to collect our needed presence data (and more absence data too, I’m sure).

The year is rapidly coming to a close, and what a busy year it has been in the Geospatial Ecology of Marine Megafauna Lab! In 2016, our members have traveled to six continents for work (all seven if we can carry Rachael’s South African conference over from the end of 2015…), led field seasons in polar, temperate, and tropical waters, presented at international conferences, processed and analyzed data, and published results. Now winter finds us holed up in our offices in Newport, and various projects are ramping up and winding down. With all of the recent turmoil 2016 has brought, it is a nice to reflect on the good work that was accomplished over the last 12 months. In writing this, I am reminded of how grateful I am to work with this talented group of people!
The year started with a flurry of field activity from our southern hemisphere projects! Erin spent her second season on the Antarctic peninsula, where she contributed to the Palmer Station Long Term Ecological Research Project.
The New Zealand blue whale project launched a comprehensive field effort in January and February, and it was a fruitful season to say the least. The team deployed hydrophones, collected tissue biopsy and fecal samples, and observed whales feeding, racing and nursing. The data collected by the blue whale team is currently being analyzed to aid in conservation efforts of these endangered animals living in the constant presence of the oil and gas industry.
Midway atoll is home to one of the largest albatross colony in the world, and Rachael visited during the winter breeding season. In addition to deploying tracking devices to study flight heights and potential conflict with wind energy development, she became acutely aware of the hazards facing these birds, including egg predation by mice and the consumption of plastic debris.
Early summertime brought red-legged kittiwakes to the remote Pribilof Islands in Alaska to nest, and Rachael met them there to study their physiology and behavior.
As the weather warmed for us in the northern hemisphere, Solene spent the austral winter with the humpback whales on their breeding grounds in New Caledonia. Her team traveled to the Chesterfield Reefs, where they collected tissue biopsy samples and photo-IDs, and recorded the whale’s songs. But Solene studies far more than just these whales! She is thoroughly examining every piece of environmental, physical, and oceanographic data she can get her hands on in an effort to build a thorough model of humpback whale distribution and habitat use.
Summertime came to Oregon, and the gray whales returned to these coastal waters. Leigh, Leila, and Todd launched into fieldwork on the gray whale stress physiology project. The poop-scooping, drone-flying team has gotten a fair bit of press recently, follow this link to listen to more!
And while Leigh, Leila, and Todd followed the grays from the water, Florence and her team watched them from shore in Port Orford, tracking their movement and behavior. In an effort to gain a better understanding of the foraging ecology of these whales, Florence and crew also sampled their mysid prey from a trusty research kayak.
With the influx of gray whales came an influx of new and visiting GEMM Lab members, as Florence’s team of interns joined for the summer season. I was lucky enough to join this group as the lab’s newest graduate student!
Our members have presented their work to audiences far and wide. This summer Leigh, Amanda, and Florence attended the International Marine Conservation Congress, and Amanda was awarded runner-up for the best student presentation award! Erin traveled to Malaysia for the Scientific Convention on Antarctic Research, and Rachael and Leigh presented at the International Albatross and Petrel Conference in Barcelona. With assistance from Florence and Amanda, Leigh led an offshore expedition on OSU’s research vessel R/V Oceanus to teach high school students and teachers about the marine environment.
Courtney fledged from the GEMM Lab nest before 2016 began, but the work she did while here was published in Marine Mammal Science this year. Congrats Courtney! And speaking of publications, additional congratulations to Solene for her publication in Marine Ecology Progress Series, Rachael for her four publications this year in PLOS ONE, Marine Ecology Progress Series, Marine Ornithology, and the Journal of Experimental Biology, and Leigh for her five publications this year in Polar Biology, Diversity and Distributions, Marine Ecology Progress Series, and Marine Mammal Science!
Wintertime in Newport has us tucked away indoors with our computers, cranking through analyses and writing, and dreaming about boats, islands, seabirds, and whales… Solene visited from the South Pacific this fall, and graced us with her presence and her coding expertise. It is a wonderful thing to have labmates to share ideas, frustrations, and accomplishments with.
As the year comes to a close, we have two newly-minted Masters of Science! Congratulations to Amanda and Erin on successfully defending their theses, and stay tuned for their upcoming publications!
We are looking forward to what 2017 brings for this team of marine megafauna enthusiasts. Happy holidays from the GEMM Lab!
