The GEMM Lab is Conference-Bound!

By Dawn Barlow, MSc Student, Department of Fisheries and Wildlife, Geospatial Ecology of Marine Megafauna Lab

Every two years, an international community of scientists gather for one week to discuss the most current and pressing science and conservation issues surrounding marine mammals. The thousands of attendees range from longtime researchers who have truly shaped the field throughout the course of their careers to students who are just beginning to carve out a niche of their own. I was able to attend the last conference, which took place in San Francisco in 2015, as an undergraduate. The experience cemented my desire to pursue marine mammal research in graduate school and beyond, and also solidified my connection with Leigh Torres and the Geospatial Ecology of Marine Megafauna Laboratory, leading to my current enrollment at Oregon State University. This year, the 22^nd Biennial Conference on the Biology of Marine Mammals takes place in Halifax, Nova Scotia, Canada. At the end of this week, Florence, Leila, Amanda, Solene, Sharon and I will head northeast to represent the GEMM Lab at the meeting!

As those of you reading this may not be able to attend, I’d like to share an overview of what we will be presenting next week. If you will be in Halifax, we warmly invite you to the following presentations. In order of appearance:

Amanda will present the final results from part of her MSc thesis on Monday in a presentation titled Comparative fine-scale harbor porpoise habitat models developed using remotely sensed and in situ data. It will be great for current GEMM Lab members to catch up with this recent GEMM Lab graduate on the other side of the continent! (Session: Conservation; Time: 4:00 pm)

On Tuesday morning, Leila will share the latest and greatest updates on her research about Oregon gray whales, including photogrammetry from drone images and stress hormones extracted from fecal samples! Her presentation is titled Combining traditional and novel techniques to link body condition and hormone variability in gray whales. This is innovative and cutting-edge work, and it is exciting to think it will be shared with the international research community. (Session: Health; Time: 10:45 am)

Did you think humpback whales have been so well studied that we must know just about everything about them? Think again! Solene will be sharing new and exciting insights from humpback whales tagged in New Caledonia, who appear to spend an intriguing amount of time around seamounts. Her talk Why do humpback whales aggregate around seamounts in South Pacific tropical waters? New insights from diving behaviour and ocean circulation analyses, will take place on Tuesday afternoon. (Session: Habitat and Distribution Speed Talks; Time: 1:30 pm)

I will be presenting the latest findings from our New Zealand blue whale research. Based on multiple data streams, we now have evidence for a unique blue whale population which is present year-round in New Zealand waters! This presentation, titled From migrant to resident: Multiple data streams point toward a resident New Zealand population of blue whales, will round out the oral presentations on Tuesday afternoon. (Session: Population Biology and Abundance; Time: 4:45 pm)

The GEMM Lab is using new technologies and innovative quantitative approaches to measure gray whale body condition and behaviors from an aerial perspective. On Wednesday afternoon, Sharon will present Drone up! Quantifying whale behavior and body condition from a new perspective on behalf of Leigh. With the emerging prevalence of drones, we are excited to introduce these quantitative applications. (Session: New Technology; Time: 11:45 am)

GoPros, kayaks, and gray whales, oh my! A limited budget couldn’t stop Florence from conducting excellent science and gaining new insights into gray whale fine-scale foraging. On Thursday afternoon, she will present Go-Pros, kayaks and gray whales: Linking fine-scale whale behavior with prey distributions on a shoestring budget, and share her findings, which she was able to pull off with minimal funds, creative study design, and a positive attitude. (Session: Foraging Ecology Speed Talks; Time: 1:55 pm)

Additional Oregon State University students presenting at the conference will include Michelle Fournet, Samara Haver, Niki Diogou, and Angie Sremba. We are thrilled to have such good representation at a meeting of this caliber! As you may know, we are all working on building the GEMM Lab’s social media presence and becoming more “twitterific”. So during the conference, please be sure to follow @GEMMLabOSU on twitter for live updates. Stay tuned!

Twitterific: The Importance of Social Media in Science

By Alexa Kownacki, Ph.D. Student, OSU Department of Fisheries and Wildlife, Geospatial Ecology of Marine Megafauna Lab

How do you create the perfect chemical formula for social media in science? (Photo Source: The Royal Society of Victoria)

There’s a never-ending debate about how active we, as scientists, should be on social media. Which social media platforms are best for communicating our science? When it comes to posting, how much is too much? Should we post a few, critical items that are highly pertinent, or push out everything that’s even closely related to our focus? Personally, my deep-rooted question revolves around privacy. What aspects of my life (and thereby my science), do I keep to myself and what do I share? I asked that exact question at a workshop last year, and I have some main takeaways.

At last year’s Southern California Marine Mammal Workshop, there was a very informative session about the role of media in science. More specifically, there was a talk on “Social Media and Communications Hot Topics” by Susan Poulton, the Chief Digital Officer of the Franklin Institute science museum in Philadelphia. She emphasized how trust factors into our media connections and networks. What was once communicated in person or on paper, has given way to this idea of virtual connections. We all have our own “bubbles”. Susan defined “bubbles” as the people who we trust. We have different classifications of bubbles: the immediate bubble that consists of our friends, family, and close colleagues, the more distant bubble that has your friends of friends and distant colleagues, and the enigma bubble that has people you find based on computer algorithms that the computer thinks you’ll find relative. Susan brought up the point that many of us stay within our immediate bubble; even though we may discuss all of the groundbreaking science with our friends and coworkers, we never burst that bubble and expand the reaches of our science into the enigma bubble. I frequently fall into this category both intentionally and unintentionally.

Many of us want to be advocates for our science. Education and outreach are crucial for communicating our message. We know this. But, can we keep what little personal life we have outside of science, private? The short of the long of it: No. Alisa Schulman-Janiger, another scientist and educator on the panel, reinforced this when she stated that she keeps a large majority of her social media posts as “public” to reach more people. Queue me being shocked. I have a decent social media presence. I have a private Facebook account, but public Twitter and LinkedIn accounts that I use only for science/academics/professional stuff, public Instagram, YouTube, and Flickr accounts that are travel and science-related, as well as a public blog that is a personal look at my life as a scientist who loves to travel. I tell you this because I am still incredibly skeptical about privacy; I keep my Facebook page about as private as possible without it being hidden. Giving up that last bit of my precious, immediate bubble and making it for the world to see feels invasive. But, I’m motivated to make sure my science reaches people who I don’t know. Giving science a personal story is what captures people; it’s why we read those articles in our Facebook feeds, and click on the interesting articles while scrolling through Twitter. Because of this, I’ve begun making more, not all, of my Facebook posts public. I’m more active on Twitter. I’m writing weekly blog posts again (we’ll see how long I can keep that up for). I’m trying to find the right balance that will keep my immediate bubble still private enough for my peace of mind and public enough that I am presenting my science to networks outside of my own—pushing through to the enigma bubble. Bubbles differ for each of us and we have to find our own balance. By playing to the flexibility of our bubbles, we can expand the horizons of our research.

This topic was recently broached while attending my first official GEMM Lab meeting. Leigh brought up social media and how we, as a lab, and as individuals, should make an effort to shine light on all the amazing science that we’re a part of. We, as a lab, are trying to be more present. Therefore, in addition to these AMAZING weekly blog posts varying from highly technical to extremely colloquial, the lab will be posting more on Twitter. And that comes to the origin of this week’s blog post’s title. Leigh said that we should be “Twitterific” and I can’t help but feel that adjective perfectly suits our current pursuit. Here’s to being Twitterific!

Building scientific friendships: A reflection on the 21st annual meeting of the Northwest Student Chapter of the Society for Marine Mammalogy

By Dawn Barlow, M.Sc. student, Department of Fisheries and Wildlife, Geospatial Ecology of Marine Megafauna Lab

I recently had the opportunity to attend and present my research at the 21^st meeting of the Northwest Student Chapter of the Society for Marine Mammalogy. This gathering represented a community of graduate and undergraduate students from the Pacific Northwest, networking and discussing their research on the biology of marine mammals. Dr. John Ford, whose name has become synonymous with killer whale research in the Pacific Northwest, delivered a compelling keynote speech on not only the history of his research, but also the history of the relationships he has built in the field and the people that have shaped the past five decades of killer whale research. This theme of cultivating scientific relationships was a thread that carried us through the weekend. Beautiful weather had us all smiling happily as we ate our lunches outside, musing about science in the sunshine. A philosopher’s café event facilitated roundtable discussions with experts in veterinary science, spatial statistics, management consulting, physiology, and marine pollution. Students were given the space to ask questions ranging from manuscript writing advice to the worth of our work in the current political climate (and write notes or doodle drawings on the paper-covered tables as we listened).

The oral and poster presentations were all very impressive. I learned that bowhead whales are likely feeding year-round in the Canadian Arctic, adjusting their dive depth to the vertical location of their copepod prey. I learned that the aerobic dive limit of stellar sea lions is more of a sliding scale rather than a switch as it is for Weddell seals. I learned that some harbor seals are estuary specialists, feeding on salmon smolt. And I learned about the importance of herring to Northeast Pacific marine mammals through an energy-based ecosystem model. I had the opportunity to present my research on the ecology of New Zealand blue whales to an audience outside of Oregon State University for the first time, and was pleased with how my presentation was received.

I may have giggled at the Canadian word for beanie, but I have to admit, “fluke tuke” has a much better ring to it than “fluke beanie”!

But beyond the scientific research itself, I also learned that there is a strong community of motivated and passionate young scientists in the Pacific Northwest studying marine mammals. Our numbers may not be many and we may be scattered across several different universities and labs, but our work is compelling and valuable. At the end of the weekend, it felt like I was saying goodbye to new friends and future colleagues. And, I learned that the magnificent size of a blue whale never fails to impress and amaze, as all the conference attendees marveled over the blue whale skeleton housed in the Beaty Biodiversity Museum at the University of British Columbia.

Many thanks to the graduate students from the University of British Columbia who organized such a successful event! At the end of the conference, it was decided that the next meeting of the Northwest Student Chapter will be hosted by the Oregon State University students here at Hatfield Marine Science Center in Newport. It is a year away, but I am already looking forward to seeing these newfound peers again and hearing how their research has progressed.

A happy student selfie at the end of a successful conference! We are looking forward to a reunion at Hatfield Marine Science Center next May!

“Marching for Science” takes many forms

By Florence Sullivan, MSc student, Oregon State University.

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.

Our competition room for NOSB 2017! Game officials are in the front of the picture, competitors at the first two desks, and parents, coaches and supporters in the back.

While millions of enthusiastic people were marching through the streets, I “Ran for Science” at the 20^th 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!

Santa Monica competes in the final round

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.

Lab members Florence, Leila, and Dawn (L to R) answer questions from the public.

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?

GEMM Lab 2016: A Year in the Life

By Dawn Barlow, MSc Student, Department of Fisheries and Wildlife, Oregon State University

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.

No heat in the lab can't stop us from solving a coding problem together on a wintery evening! — Solving a coding problem together on a wintery evening.

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!

Oceanus Day Three: Dolphin Delights

by Florence Sullivan, MSc student

Our third day aboard the Oceanus began in the misty morning fog before the sun even rose. We took the first CTD cast of the day at 0630am because the physical properties of the water column do not change much with the arrival of daylight. Our ability to visually detect marine mammals, however, is vastly improved with a little sunlight, and we wanted to make the best use of our hours at sea possible.

Our focus on day three was the Astoria canyon – a submarine feature just off the Oregon and Washington coast. Our first oceanographic station was 40 miles offshore, and 1300 meters deep, while the second was 20 miles offshore and only 170 meters deep. See the handy infographic below to get a perspective on what those depths mean in the grand scheme of things. From an oceanographic perspective, the neatest finding of the day was our ability to detect the freshwater plume coming from the Columbia River at both those stations despite their distance from each other, and from shore! Water density is one of the key characteristics that oceanographers use to track parcels of water as they travel through the ocean conveyor belt. Certain bodies of water (like the Mediterranean Sea, or the Atlantic or Pacific Oceans) have distinct properties that allow us to recognize them easily. In this case, it was very exciting to “sea” the two-layer system we had gotten used to observing overlain with a freshwater lens of much lower salinity, higher temperature, and lower density. This combination of freshwater, saltwater, and intriguing bathymetric features can lead to interesting foraging opportunities for marine megafauna – so, what did we find out there?

Morning conditions were almost perfect for marine mammal observations – glassy calm with low swell, good, high, cloud cover to minimize glare and allow us to catch the barest hint of a blow….. it should come as no surprise then, that the first sightings of the day were seabirds and tuna!

I didn't catch any photos of the Tuna, so here's some mola mola we spotted. photo credit: Florence Sullivan — I didn’t catch any photos of the tuna, so here’s some sunfish we spotted. photo credit: Florence Sullivan

One of the best things about being at sea is the ability to look out at the horizon and have nothing but water staring back at you. It really drives home all the old seafaring superstitions about sailing off the edge of the world. This close to shore, and in such productive waters, it is rare to find yourself truly alone, so when we spot a fishing trawler, there’s already a space to note it in the data log. Ships at sea often have “follower” birds – avians attracted by easy meals as food scraps are dumped overboard. Fishing boats usually attract a lot of birds as fish bycatch and processing leftovers are flushed from the deck. The birders groan, because identification and counts of individuals get more and more complicated as we approach other vessels. The most thrilling bird sighting of the day for me were the flocks of a couple hundred fork-tailed storm petrels.

I find it remarkable that such small birds are capable of spending 80% of their life on the open ocean, returning to land only to mate and raise a chick. Their nesting strategy is pretty fascinating too – in bad foraging years, the chick is capable of surviving for several days without food by going into a state of torpor. (This slows metabolism and reduces growth until an adult returns.)

Just because the bird observers were starting to feel slightly overwhelmed, doesn’t mean that the marine mammal observers stopped their own survey. The effort soon paid off with shouts of “Wait! What are those splashes over there?!” That’s the signal for everyone to get their binoculars up, start counting individuals, and making note of identifying features like color, shape of dorsal fin, and swimming style so that we can make an accurate species ID. The first sighting, though common in the area, was a new species for me – Pacific white sided dolphins!

A pod of thirty or so came to ride our bow wake for a bit, which was a real treat. But wait, it got better! Shortly afterward, we spotted more activity off the starboard bow. It was confusing at first because we could clearly see a lot of splashes indicating many individuals, but no one had glimpsed any fins to help us figure out the species. As the pod got closer, Leigh shouted “Lissodelphis! They’re lissodelphis!” We couldn’t see any dorsal fins, because northern right whale dolphins haven’t got one! Then the fly bridge became absolute madness as we all attempted to count how many individuals were in the pod, as well as take pictures for photo ID. It got even more complicated when some more pacific white sided dolphins showed up to join in the bow-riding fun.

All told, our best estimates counted about 200 individuals around us in that moment. The dolphins tired of us soon, and things continued to calm down as we moved further away from the fishing vessels. We had a final encounter with an enthusiastic young humpback who was breaching and tail-slapping all over the place before ending our survey and heading towards Astoria to make our dock time.

As a Washington native who has always been interested in a maritime career, I grew up on stories of The Graveyard of the Pacific, and how difficult the crossing of the Columbia River Bar can be. Many harbors have dedicated captains to guide large ships into the port docks. Did you know the same is true of the Columbia River Bar? Conditions change so rapidly here, the shifting sands of the river mouth make it necessary for large ships to receive a local guest pilot (often via helicopter) to guide them across. The National Motor Lifeboat School trains its students at the mouth of the river because it provides some of “the harshest maritime weather conditions in the world”. Suffice it to say, not only was I thrilled to be able to detect the Columbia River plume in our CTD profile, I was also supremely excited to finally sail across the bar. While a tiny part of me had hoped for a slightly more arduous crossing (to live up to all the stories you know), I am happy to report that we had glorious, calm, sunny conditions, which allowed us all to thoroughly enjoy the view from the fly bridge.

Cape Disappointment Lighthouse at the Columbia River Bar.

Finally, we arrived in Astoria, loaded all our gear into the ship’s RHIB (Ridged Hulled Inflatable Boat), lowered it into the river, descended the rope ladder, got settled, and motored into port. We waved goodbye to the R/V Oceanus, and hope to conduct another STEM cruise aboard her again soon.

Now if the ground would stop rolling, that would be just swell.

Last but not least, here are the videos we promised you in Oceanus Day Two – the first video shows the humpback lunge feeding behavior, while the second shows tail slapping. Follow our youtube channel for more cool videos!

Oceanus Day Two: All the Albatrosses

By Amanda Holdman and Florence Sullivan

Today got off to a bright and early start. As soon as daylight permitted, we had spotters out on duty looking for more marine mammals. We began to survey at the north end of Heceta bank, where we again encountered many humpback whales lunge feeding. We broke transect, and got some great video footage of a pair them – so check our youtube channel next week – we’ll upload the video as soon as we get back to better internet (dial up takes some getting used to again – the whales don’t know about highspeed yet).

After working with the humpbacks to capture photo-id data for about an hour, we turned south, and ran parallel to Heceta bank until we reached the southern edge. Along the way, we counted 30 humpbacks, and many California gulls, marbled murrelets, pink footed shearwaters, and sooty shearwaters.

After lunch, we conducted a CTD cast to see how conditions might be different between the southern and northern edges of the bank. Surface temperatures increased from 12.09C to 13.2C while bottom temperatures decreased from 8.7C to 7.8C. The northern station was a textbook perfect two layer system. It had a well mixed surface layer with a steep pycnocline separating it from the colder, saltier, denser, bottom layer. The southern station still had two layers, but the pycnocline (the depth where a rapid change in density occurs, which delineates the edges of water masses) was not as steep. We are interested in these discreet measurements of ocean conditions because areas of high primary productivity (the green chlorophyll-a line) are often re-occurring hot spots of food for many levels of the food chain. Since we can’t phone the whales and ask them where to meet up, we use clues like these to anticipate the best place to start looking.

We next turned west to transect the continental shelf break. Here, we were hoping to observe changes in species composition as waters got deeper, and habitat changed. The shelf break is often known as an area of upwelling and increased primary productivity, which can lead to concentrations of marine predators taking advantage of aggregations of prey. As we moved further offshore, everyone was hoping for some sperm whales, or maybe some oceanic dolphin species, and if we’re really lucky, maybe a beaked whale or two.

Today our students learned the lesson of how difficult marine mammal observation can be when our target species spend the majority of their lives underwater – where we can’t see them. While there were a couple of hours of mammal empty water in there, observers were kept busy identifying long tailed- jaegers, cassin’s auklets, murrelets, petrels, shearwaters, fulmars, and so many black-footed albatrosses, that they almost became “normal”. That being said, we did spot a fin whale, a few groups of Dall’s porpoise, and three pacific-white-sided dolphins. Unexpectedly, we also saw an unidentified shark, and several sunfish (mola mola)!

Last but not least, we engaged in a long standing oceanographic tradition, which is to draw on Styrofoam cups, and send them down to Davy Jone’s Locker attached to the CTD. When you bring them back up, the pressure has caused them to shrink to a fraction of their original size, which is an excellent demonstration of the crushing power of pressure (and why its harder to build a submarine than a rocket).

Shrunken cups! The first row have been sent down to 1400m, while the back row are still full size!

Now, we are steaming north toward Astoria Canyon, where we hope to make some more sightings in the morning. Stand by for news from our final day at sea.

R/V Oceanus Day One: Hungry Hungry Humpbacks

By Florence Sullivan and Amanda Holdman

The GEMM lab is adventuring out into the wild blue yonder of open ocean sampling and educational outreach! Leigh is the chief scientist onboard the R/V Oceanus for the next two days as we sail through Oregon waters in search of marine megafauna. Also onboard are four local teachers and five high school students who are learning the tricks of the trade. Amanda and I are here to help teach basic oceanography and distance sampling techniques to our enthusiastic students.

We started the morning with safety briefings, and headed out through the Newport breakwater, direction: Stonewall Bank. Stonewall is a local bathymetric feature where upwelling often occurs, leading to a productive ecosystem for both predators and prey. Even though our main sampling effort will be offshore this trip, we didn’t even make out of the harbor before recording our first gray whale and California sea lion sightings.

Our students (and their teachers) are eager and quick to catch on as we teach them new methodologies. Amanda and I had prepared presentations about basic oceanographic and distance sampling methods, but really the best way to learn is to jump in and go. We’ve set up a rotation schedule, and everyone is taking turns scanning the ocean for critters, deploying and recovering the CTD, logging data, and catching plankton.

So far, we have spotted gray whales, sea lions, a pod of (lightning speed) killer whales, lots of seagulls, northern fulmars, sooty shearwaters, storm petrels, and cormorants, but today’s highlight has to the last sighting of ~42 humpback whales. We found them at the Northern edge of Heceta Bank – a large rocky reef which provides structural habitat for a wide variety of marine species. As we approached the area, we spotted one whale, and then another. At first, our spotters had no trouble inputting the data, getting photo-ID shots, and distinguishing one whale from the next, but as we continued, we were soon overwhelmed. With whale blows surrounding us on all sides, it was hard to know where to look first – here a surface lunge, there, a breach, a spout, a fluke, a flipper slap! The surface activity was so dense and enthralling, it took a few moments before realizing there were some sea lions in the feeding frenzy too!

We observed the group, and tried to document as many individuals as possible as the sunset faded into night. When poor visibility put a stop to the visuals, we hurried to do a plankton tow and CTD cast to find some environmental insights for such a gathering. The CTD revealed a stratified water column, with two distinct layers, and the plankton tow brought up lots of diatoms and krill. As one of the goals of this cruise is to explore how marine mammals vary with ocean gradients, this is a pretty cool way to start.

A long day observing has left us all exhausted, but not too tired to share our excitement. Stay tuned for more updates from the briny blue!

Outreach and education: sharing the stoke

By Erin Pickett

My friend Matt and I chased after a butterfly waving our nets through the air, jumping and swatting at the trees. For a brief moment I considered how ridiculous I probably looked running around in circles, looking up at the sky and not at my feet or where I was going. I was just about to step on a wasp nest before I came to my senses. The butterfly got away as I looked up to see our group of middle school students walking back to us after finishing their snack break.

It was day three of “Ecosystem sleuths” summer camp, and while Matt and I were helping lead this camp, we were certainly not going to let that stop us from having some good old fashioned fun catching bugs.

Last week my fellow fisheries and wildlife grad students and I walked away from our computers and experiments and took a break from thesis writing and summer field work to spend the week with a group of local middle and high school students. We ran a weeklong ecology-themed summer camp sponsored by Oregon State’s STEM Academy and inspired by our desire to share what we love with young students who are interested in science. This is what I call “sharing the stoke”.

We hoped to teach our students about a few broad and important ecological concepts while introducing them to field methods and sampling techniques. Neither the Corvallis city limits nor IACUC could hold us back and we managed to bring a menagerie of animals into the classroom including polar bears, elk and sharks. We have OSU’s extensive research and teaching collections to thank for giving our students a chance to handle some cool skulls, pelts and other preserved specimens.

One afternoon I led the students in crafting homemade humpback whale flukes, so that we could practice re-sighting them and estimating population sizes using the mark-recapture method. In between lectures and lab activities, with the help of YouTube, we watched two male elephant seals fight for dominance on a northern California beach and got a birds-eye view of a bald eagle soaring through a canyon. One student couldn’t help but jump up and down while watching this video. At the end of the week took the students to Hesthavn Nature Center and spent two afternoons outside collecting terrestrial and aquatic invertebrates, identifying birds, and learning how to pin insects.

After our students left each afternoon we’d all sit down to discuss the next day’s plan. Exhausted, we’d finish the last of the juice boxes and granola bars and wonder how teachers do what they do. Hats off to you, teachers!

Sharing the Science! Outreach at the GEMM Lab

Hello Everyone,

My name is Florence, and I’m here to update you on all the amazing outreach activities that the GEMM lab has participated in this past month!

We started on April 11, with the HMSC-wide Marine Science Day celebrations. This year was particularly exciting because the Hatfield Marine Science Center is turning 50 years old! Along with the rest of our colleagues at the Marine Mammal Institute, we presented posters detailing our projects, had a few hands on activities such as ‘spot the whale’ – a bit of a scavenger hunt designed to give people a taste of how difficult it can be to spot marine mammals, and answered questions about our work. It was quite a success!

On April 19, I went down to Port Orford, OR to participate in “Redfish Rocks on the Docks” an outreach event showcasing all the exciting research being done in conjunction with the Redfish Rocks Marine Reserve near Port Orford. I presented a poster about my thesis project: Assessment of vessel disturbance to foraging gray whales on the Oregon Coast to promote sustainable ecotourism, and answered questions while leading folks through our ‘stay warm like a whale’ blubber glove activity. It was a beautiful sunny day, but so windy that at times we joked that our tables looked more like geology presentations than marine biology due to all the rocks holding everyone’s papers, photos, and flyers down! Many of the folks who I will be collaborating with over the course of this project also had their own informational booths; South Coast Tours, Redfish Rocks Community Team, and the Oregon Marine Reserves Program. The Surfrider Foundation and CoastWatch also had interesting activities and information to share about marine debris and conservation of our oceans. My favorite moment of the day was when I was explaining to a little girl how gray whales need to eat a lot of mysid shrimp in order to maintain their blubber to stay warm in the frigid ocean – and she intuitively made the jump from the blubber glove to the wetsuit she uses to go swimming! It was wonderful to see her thinking critically about the different strategies for heat retention in water.

Finally, yesterday, almost the entire lab gave presentations at the Northwest Student Society of Marine Mammals Annual Meeting. The meeting was attended by ~80 interested students and researchers from a number of outstanding universities including; Western Washington University, University of Washington, Portland State, Stanford University and of course, Oregon State University. The day began with an excellent introductory presentation by Dr. Ari Friedlander of our sister BTBEL Lab, and then it was on to student presentations. Courtney and I presented in the ‘Human Dimensions’ forum on the possibilities of citizen science in marine mammal research and gray whale foraging ecology respectively. At lunch, our valiant leader, Leigh, took part in a discussion panel and fielded questions from the audience concerning current advances in technology and possible applications to field work as well as giving professional development advice. A few take away messages; Technology can provide wonderful insights, but one should not use a tool just to use a tool. Rather, it is important to first ask your question, and then build your methodology and choose your tools in a manner most precisely able to answer the questions at hand. In regards to professional development, do not discount the benefit of getting international experience – A broad perspective on possible solutions, and strong international collaborations will be necessary to solve many of the management issues facing our oceans today. During the ‘Bioacoustics’ session, Amanda presented her work concerning harbor porpoise spatial distribution. Finally, Solène presented her work on Maui’s dolphins during the ‘Space and Time’ Session, and walked out having earned the ‘Best Presentation’ Award!! Over the past few months that she has been visiting us, she has been a dedicated colleague and a wonderfully cheerful presence in the lab, and it was fantastic to see all her hard work being recognized in this public forum. Overall, this NWSSMM conference was a great opportunity to see what other students in the Pacific Northwest region are working on, opened doors for future collaborations and gave us ideas for future projects.
