With new approaches come new insights: What we do and don’t know about blue whales

By Dawn Barlow, MSc student, Department of Fisheries and Wildlife

A few weeks ago, my labmate Dom’s blog reminded me that it is important to step back from the data and appreciate the magnificence of the animals we study from time to time. I have the privilege of studying the largest creatures on the planet. When people hear that I study blue whales, I often get a series of questions: Just how big are they, really? How many are there? Where do they migrate? Where do they breed? Despite the fact that humans hunted blue whales nearly to extinction [1,2], we still know next to nothing about these giants. The short answer to many of those questions is, “Well we don’t really know, but we’re working on it!” Which brings me back to taking time to marvel at these animals for a bit. Isn’t it remarkable that the largest animals on earth can be so mysterious?

Last year at this time we were aboard a research vessel in New Zealand surveying for blue whales and collecting a myriad of biological data to try and glean some insight into their lives. This winter I am processing those data and conducting a literature review to get a firm grasp on what others have found before about blue whale foraging and bioenergetics. On any given Tuesday morning Leigh and I can be found musing about the mechanics of a baleen whale jaw, about what oceanographic boundaries in the water column might be meaningful to a blue whale, about how we might quantify the energy expenditure of a foraging whale. Here are some of those musings.

Humans are, for the most part, terrestrial creatures. Even those of us that would prefer to spend most of our time near, on, or in the water are limited in what we can observe of marine life. Much of the early data that was collected on blue whales came from whaling catches. Observations of anatomy and morphology were made once the whales were killed and taken out of their marine environment. This was not long ago—Soviet whaling continued into the 1970’s in New Zealand [3]. Because baleen whales are long lived (exact age unknown for blue whales but a bowhead whale was estimated to be at least 150 years old [4]) it is entirely possible that blue whales living today remember being hunted by whalers. Observing whales in their natural state is not easy, particularly post-commercial whaling when they are few and far between.

Yet, where there is a challenge, clever people develop creative approaches and new technologies, leading to new insights. High-quality cameras have allowed scientists to photograph whales for individual identification—a valuable first step in figuring out how many there are and where they go [5]. Satellite tags have allowed scientists to track the movement of blue whales in the North Pacific and Indian Oceans, a first step in learning where these whales might go to breed. However, no blue whale breeding ground has definitively been discovered yet…

What does a whale do when it is below the surface, out of sight of our terrestrial eyes? A study from 1986 that attempted to calculate the prey demands of a whale assumed that whenever a whale was submerged, it was feeding [6]. A big assumption, but a starting place without any dive data. By 2002, tags equipped with time-depth recorders (TDR) had already revealed that blue whales make dives of variable depths and shapes [7]. But, what determines a whale’s path underwater, where they must conserve as much oxygen as they can while finding and exploiting patches of prey? The advent of digital acoustic recording tags (DTAGs) in the early 2000s have allowed scientists to measure the fine-scale movements of whales in three dimensions [8]. These tags can capture the kinematic signatures (based on pitch, roll, and yaw) of lunge-feeding events below the surface. And with the addition of echosounder technology that allows us to map the prey field, we can now link feeding events with characteristics of the prey present in the area [9]. With this progression of technology, curiosity and insight we now know that blue whales are not indiscriminate grazers, but instead pass up small patches of krill in favor of large, dense aggregations where they will get the most energetic bang for their buck.

The advent of unmanned aerial systems (UAS, a.k.a. “drones”) have provided yet another unique perspective on the lives of these whales. In 2016, our New Zealand blue whale team recorded nursing behavior between a mother and calf. In 2017, we were able to capture surface lunge feeding behavior from an aerial perspective, both for the first time.

Through innovative approaches, we are beginning to understand the lives of these mysterious giants. As is true for many things, the more we learn, the more questions we have. Through the GEMM Lab’s blue whale project, we have determined that a unique population of blue whales occupies the South Taranaki Bight region of New Zealand year-round; they do not simply migrate through as their current threat classification status indicates [10]. But what are their distribution patterns? Can we predict when and where whales are most likely to be in the South Taranaki Bight? Does this population have a different foraging strategy than their Californian, Chilean, or Antarctic counterparts? These are the things we are working on unraveling, and that will aid in their conservation. In the meantime, I’ll keep musing about what we don’t know, and remember to keep marveling at what we do know about the largest creatures on earth.

What REALLY is a Wildlife Biologist?

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

The first lecture slide. Source: Lecture1_Population Dynamics_Lou Botsford

This was the very first lecture slide in my population dynamics course at UC Davis. Population dynamics was infamous in our department for being an ultimate rite of passage due to its notoriously challenging curriculum. So, when Professor Lou Botsford pointed to his slide, all 120 of us Wildlife, Fish, and Conservation Biology majors, didn’t know how to react. Finally, he announced, “This [pointing to the slide] is all of you”. The class laughed. Lou smirked. Lou knew.

Lou knew that there is more truth to this meme than words could express. I can’t tell you how many times friends and acquaintances have asked me if I was going to be a park ranger. Incredibly, not all—or even most—wildlife biologists are park rangers. I’m sure that at one point, my parents had hoped I’d be holding a tiger cub as part of a conservation project—that has never happened. Society may think that all wildlife biologists want to walk in the footsteps of the famous Steven Irwin and say thinks like “Crikey!”—but I can’t remember the last time I uttered that exclamation with the exception of doing a Steve Irwin impression. Hollywood may think we hug trees—and, don’t get me wrong, I love a good tie-dyed shirt—but most of us believe in the principles of conservation and wise-use A.K.A. we know that some trees must be cut down to support our needs. Helicoptering into a remote location to dart and take samples from wild bear populations…HA. Good one. I tell myself this is what I do sometimes, and then the chopper crashes and I wake up from my dream. But, actually, a scientist staring at a computer with stacks of papers spread across every surface, is me and almost every wildlife biologist that I know.

There is an illusion that wildlife biologists are constantly in the field doing all the cool, science-y, outdoors-y things while being followed by a National Geographic photojournalist. Well, let me break it to you, we’re not. Yes, we do have some incredible opportunities. For example, I happen to know that one lab member (eh-hem, Todd), has gotten up close and personal with wild polar bear cubs in the Arctic, and that all of us have taken part in some work that is worthy of a cover image on NatGeo. We love that stuff. For many of us, it’s those few, memorable moments when we are out in the field, wearing pants that we haven’t washed in days, and we finally see our study species AND gather the necessary data, that the stars align. Those are the shining lights in a dark sea of papers, grant-writing, teaching, data management, data analysis, and coding. I’m not saying that we don’t find our desk work enjoyable; we jump for joy when our R script finally runs and we do a little dance when our paper is accepted and we definitely shed a tear of relief when funding comes through (or maybe that’s just me).

What I’m trying to get at is that we accepted our fates as the “scientists in front of computers surrounded by papers” long ago and we embrace it. It’s been almost five years since I was a senior in undergrad and saw this meme for the first time. Five years ago, I wanted to be that scientist surrounded by papers, because I knew that’s where the difference is made. Most people have heard the quote by Mahatma Gandhi, “Be the change that you wish to see in the world.” In my mind, it is that scientist combing through relevant, peer-reviewed scientific papers while writing a compelling and well-researched article, that has the potential to make positive changes. For me, that scientist at the desk is being the change that he/she wish to see in the world.

One of my favorite people to colloquially reference in the wildlife biology field is Milton Love, a research biologist at the University of California Santa Barbara, because he tells it how it is. In his oh-so-true-it-hurts website, he has a page titled, “So You Want To Be A Marine Biologist?” that highlights what he refers to as, “Three really, really bad reasons to want to be a marine biologist” and “Two really, really good reasons to want to be a marine biologist”. I HIGHLY suggest you read them verbatim on his site, whether you think you want to be a marine biologist or not because they’re downright hilarious. However, I will paraphrase if you just can’t be bothered to open up a new tab and go down a laugh-filled wormhole.

Really, Really Bad Reasons to Want to be a Marine Biologist:

To talk to dolphins. Hint: They don’t want to talk to you…and you probably like your face.
You like Jacques Cousteau. Hint: I like cheese…doesn’t mean I want to be cheese.
Hint: Lack thereof.

Really, Really Good Reasons to Want to be a Marine Biologist:

Work attire/attitude. Hint: Dress for the job you want finally translates to board shorts and tank tops.
You like it. *BINGO*

In summary, as wildlife or marine biologists we’ve taken a vow of poverty, and in doing so, we’ve committed ourselves to fulfilling lives with incredible experiences and being the change we wish to see in the world. To those of you who want to pursue a career in wildlife or marine biology—even after reading this—then do it. And to those who don’t, hopefully you have a better understanding of why wearing jeans is our version of “business formal”.

Skype a Scientist – Are you smarter than a middle schooler?

By Florence Sullivan, MSc

What do baby whales eat?

Does the mom whale take care of the baby whale alone?

How do whales communicate?

What are their behaviors?

These are the questions 4^th grade students half a world away asked me. They are studying biodiversity and were very curious to meet a real life scientist. It was 2:00pm on a Tuesday here in Newport, OR, while in Australia, this classroom full of students was sitting in their 9:00am Wednesday science class. We had an hour-long conversation about gray whale behaviors, habitat, life cycle, and general biology – all thanks to the wonders of science, technology and the computer program, Skype. The next day, I did it all again, and Skyped in to a classroom in British Columbia, to field questions about gray whales, right whales and science careers from a group of enthusiastic 5^th and 6^th grade students.

A class of Australian 4th graders had many imaginative questions for me through the Skype a Scientist Program.

But how in the world did I end up answering questions over Skype for a classroom full of kids in the first place? Like many good things, it began with a conversation. During the 2016 USA election cycle, it became apparent that many people in this country distrust scientists. Sarah McAnulty, a PhD student at the University of Connecticut who studies the immune system of bob tail squid, had already been engaging in informal science communication through a profile on tumblr. But posting things on tumblr is like preaching to the choir – your audience tends to be people who are already interested in your subject. If the problem is trying to change the public perception of scientists from aloof and insular to trustworthy and approachable, you need to start by finding people who have a lot of questions, and few pre-existing prejudices. Who fits the bill perfectly? Kids!

After conversations with colleagues, she came up with the idea of using Skype to reach classrooms of students outside of the range where scientists usually congregate (large cities and universities). Sarah started by connecting a handful of UConn colleagues with K-12 teachers through Facebook, but the idea quickly gained steam through mentions at a scientific conference, posts on the ‘March for Science’ Facebook group, media coverage, and word-of-mouth sharing between colleagues on both the teaching and the research side of the story. Now, there is a full-fledged website (https://www.skypeascientist.com/) where teachers and scientists can sign up to be matched based on availability, topic, and sometimes, demographic. When pairing classrooms and scientists, Sarah makes an effort for minority students (whether this means race, gender, disability, language, or other) to see themselves represented in the scientists they get to talk to, if possible. Representation matters –we are beyond the age of old white men in lab coats being the only ‘real scientists’ represented in media, but unfortunately, the stereotype is not dead yet! In less than a year, the program has grown to over 1900 scientists, with new fields of expertise being added frequently as people spread the word and get interested. The program has been, and promises to continue being, an excellent resource for teachers who want to show the relevance of the subjects being discussed in their classrooms. As evidenced by the fact that I spoke with a classroom in Australia, this is a global program – check out the maps below to see where students and scientists are coming from!

This map shows the locations of all participating classrooms, current on Oct 12, 2017.

As for myself, I got involved because my lab mate, Alexa, mentioned how much fun she had Skyping with students. The sign-up process was incredibly easy, and when I got matched with two classrooms, the organizers even provided a nice mad-libs style ‘fill in the blank’ introduction letter so that I didn’t waste time agonizing over how to introduce myself.

I sent the classrooms the youtube video of my field work, and a couple of these blog posts, and waited to hear back. I was very impressed with the 5^th/6^th grade class from British Columbia because the teacher actually let the students take the lead from the get-go. One of the students replied to my email, told me what they were studying, and started the process of scheduling a meeting time that would work for both of us. When I called in, two other students took the reins, and acted as spokespeople for the rest of their classmates by repeating questions from the back of the room so that I could hear everything clearly. It was so fun to see and hear the enthusiasm of the students as they asked their questions. Their deep curiosity and obvious excitement about the subject matter was contagious, and I found my own tone, body language, and attitude shifting to match theirs as I helped them discover the building blocks of marine ecology that I have long accepted as normal. This two way street of learning is a good reminder that we all start somewhere.

If you are interested in the program at all, I encourage you to sign up at this link: (https://www.skypeascientist.com/). Who knows, engaging with kids like this just might remind you of the innocent curiosity of childhood that brought you to your scientific career in the first place.

Here are some of my favorite question that I was asked, and the responses I gave:

How do gray whales communicate?

With songs and underwater sounds! Check out this great website for some great examples, and prepare to be amazed! (I played the Conga and the belch-like call during the skype session, much to the amusement of the students) https://www.sanignaciograywhales.org/project/acoustics/

What do baby whales eat?

Whales are mammals just like us, so believe it or not, baby whales drink their mother’s milk!

How long have you been a marine special ecologist for?

My favorite bit here was the mis-spelling, which made me a ‘special’ ecologist instead of a ‘spatial’ ecologist. So I talked about how spatial ecology is a special type of ecology where we look at how big things move in the ocean!

My question is, can a grey whale bite people if people come close to them?
This was a chance to show off our lab baleen samples! I also took the time to look this up, and it turns out that bite is defined as “using teeth to cut into something” and a gray whale doesn’t have teeth! Instead, they have baleen, which they use to sieve stuff out of the water. So I don’t think you need to worry about getting bitten by a gray whale. That being said, it’s important not to get close to them, because they are so much bigger than us that they could hurt us on accident.

When you go out to see the whales, why don’t you use slightly bigger boats so you don’t flip over if the whale gets too close to you, or when you get to close to the whale?
Our research kayak is a never-ending delight. It’s less expensive than a bigger boat, and doesn’t use fossil fuels. We want to be quiet in the water and not disturb the whale, and actively avoid getting within 100 yards so there shouldn’t be any danger. Sometimes the whales surprise us though, and we have to be careful. In this case, everyone has safety training and is able to rescue themselves if the boat should flip.

(This led to an entertaining discussion of field safety, and the appalling idea that I would make my interns jump out of the kayak into cold Pacific water on purpose during safety training)

There were many more questions, but why don’t you give the program a try, and see what kind of questions you get to answer?!

A Marine Mammal Odyssey, Eh!

By Leila Lemos, PhD student

Dawn Barlow, MS student

Florence Sullivan, MS

The Society for Marine Mammalogy’s Biennial Conference on the Biology of Marine Mammals happens every two years and this year the conference took place in Halifax, Nova Scotia, Canada.

Logo of the Society for Marine Mammalogy’s 22nd Biennial Conference on the Biology of Marine Mammals, 2017: A Marine Mammal Odyssey, eh!

The conference started with a welcome reception on Sunday, October 22^nd, followed by a week of plenaries, oral presentations, speed talks and posters, and two more days with different workshops to attend.

This conference is an important event for us, as marine mammalogists. This is the moment where we get to share our projects (how exciting!), get important feedback, and hear about different studies that are being conducted around the world. It is also an opportunity to network and find opportunities for collaboration with other researchers, and of course to learn from our colleagues who are presenting their work.

The GEMM Lab attending the opening plenaries of the conference!

The first day of conference started with an excellent talk from Asha de Vos, from Sri Lanka, where she discussed the need for increased diversity (in all aspects including race, gender, nationality, etc.) in our field, and advocated for the end of “parachute scientists” who come into a foreign (to them) location, complete their research, and then leave without communicating results, or empowering the local community to care or act in response to local conservation issues. She also talked about the difficulty that researchers in developing countries face accessing research that is hidden behind journal pay walls, and encouraged everyone to get creative with communication! This means using blogs and social media, talking to science communicators and others in order to get our stories out, and no longer hiding our results behind the ivory tower of academia. Overall, it was an inspirational way to begin the week.

On Thursday morning we heard Julie van der Hoop, who was this year’s recipient of the F.G. Wood Memorial Scholarship Award, present her work on “Drag from fishing gear entangling right whales: a major extinction risk factor”. Julie observed a decrease in lipid reserves in entangled whales and questioned if entanglements are as costly as events such as migration, pregnancy or lactation. Tags were also deployed on whales that had been disentangled from fishing gear, and researchers were able to see an increase in whale speed and dive depth.

Julie van der Hoop talks about different drag forces of fishing gears
on North Atlantic Right Whales.

There were many other interesting talks over the course of the week. Some of the talks that inspired us were:

— Stephen Trumble’s talk “Earplugs reveal a century of stress in baleen whales and the impact of industrial whaling” presented a time-series of cortisol profiles of different species of baleen whales using earplugs. The temporal data was compared to whaling data information and they were able to see a high correlation between datasets. However, during a low whaling season concurrent to the World War II in the 40’s, high cortisol levels were potentially associated to an increase in noise from ship traffic.

— Jane Khudyakov (“Elephant seal blubber transcriptome and proteome responses to single and repeated stress”) and Cory Champagne (“Metabolomic response to acute and repeated stress in the northern elephant seal”) presented different aspects of the same project. Jane looked at down/upregulation of genes (downregulation is when a cell decreases the quantity of a cellular component, such as RNA or protein, in response to an external stimulus; upregulation is the opposite: when the cell increases the quantity of cellular components) to check for stress. She was able to confirm an upregulation of genes after repeated stressor exposure. Cory checked for influences on the metabolism after administering ACTH (adrenocorticotropic hormone: a stimulating hormone that causes the release of glucocorticoid hormones by the adrenal cortex. i.e., cortisol, a stress related hormone) to elephant seals. By looking only at the stress-related hormone, he was not able to differentiate acute from chronic stress responses. However, he showed that many other metabolic processes varied according to the stress-exposure time. This included a decrease in amino acids, mobilization of lipids and upregulation of carbohydrates.

— Jouni Koskela (“Fishing restrictions is an essential protection method of the Saimaa ringed seal”) talked about the various conservation efforts being undertaken for the endangered Lake Saimaa ringed seal. Gill nets account for 90% of seal pup mortality, but if new pups can reach 20kg, only 14% of them will drown in these fishing net entanglements. Working with local industry and recreational interests, increased fishing restrictions have been enacted during the weaning season. In addition to other year-round restrictions, this has led to a small, but noticeable upward trend in pup production and population growth! A conservation success story is always gratifying to hear, and we wish these collaborative efforts continued future success.

— Charmain Hamilton (“Impacts of sea-ice declines on a pinnacle Arctic predator-prey relationship: Habitat, behaviour, and spatial overlap between coastal polar bears and ringed seals”) gave a fascinating presentation looking at how changing ice regimes in the arctic are affecting spatial habitat use patterns of polar bears. As ice decreases in the summer months, the polar bears move more, resulting in less spatial overlap with ringed seal habitat, and so the bears have turned to targeting ground nesting seabirds. This spatio-temporal mismatch of traditional predator/prey has drastic implications for arctic food web dynamics.

— Nicholas Farmer’s presentation on a Population Consequences of Disturbance (PCoD) model for assessing theoretical impacts of seismic survey on sperm whale population health had some interesting parallels with new questions in our New Zealand blue whale project. By simulating whale movement through modeled three-dimensional sound fields, he found that the frequency of the disturbance (i.e., how many days in a row the seismic survey activity persisted) was very important in determining effects on the whales. If the seismic noise persists for many days in a row, the sperm whales may not be able to replenish their caloric reserves because of ongoing disturbance. As you can imagine, this pattern gets worse with more sequential days of disturbance.

— Jeremy Goldbogen used suction cup tags equipped with video cameras to peer into an unusual ecological niche: the boundary layer of large whales, where drag is minimized and remoras and small invertebrates compete and thrive. Who would have thought that at a marine mammal conference, a room full of people would be smiling and laughing at remoras sliding around the back of a blue whale, or barnacles filter feeding as they go for a ride with a humpback whale? Insights from animals that occupy this rare niche can inform improvements to current tag technologies.

The GEMM Lab was well represented this year with six different talks: four oral presentations and two speed talks! It is evident that all of our hard work and preparation, such as practicing our talks in front of our lab mates two weeks in advance, paid off. All of the talks were extremely well received by the audience, and a few generated intelligent questions and discussion afterwards – exactly as we hoped. It was certainly gratifying to see how packed the room was for Sharon’s announcement of our new method of standardizing photogrammetry from drones, and how long the people stayed to talk to Dawn after her presentation about an unique population of New Zealand blue whales – it took us over an hour to be able to take her away for food and the celebratory drinks she deserved!

We are not always serious, we can get silly sometimes!

The weekend after the conference many courageous researchers who wanted to stuff their brains with even more specialized knowledge participated in different targeted workshops. From 32 different workshops that were offered, Leila chose to participate in “Measuring hormones in marine mammals: Current methods, alternative sample matrices, and future directions” in order to learn more about the new methods, hormones and matrices that are being used by different research groups and also to make connections with other endocrinologist researchers. Solène participated in the workshop “Reproducible Research with R, Git, and GitHub” led by Robert Shick. She learned how to better organize her research workflow and looks forward to teaching us all how to be better collaborative coders, and ensure our analysis is reproducible by others and by our future selves!

On Sunday none of us from the GEMM Lab participated in workshops and we were able to explore a little bit of the Bay of Fundy, an important area for many marine mammal species. Even though we didn’t spot any marine mammals, we enjoyed witnessing the enormous tidal exchange of the bay (the largest tides in the world), and the fall colors of the Annaoplis valley were stunning as well. Our little trip was fun and relaxing after a whole week of learning.

It is amazing how refreshing it is to participate in a conference. So many ideas popping up in our heads and an increasing desire to continue doing research and work for conservation of marine mammals. Now it’s time to put all of our ideas and energy into practice back home! See you all in two years at the next conference in Barcelona!

Conservation at the Science-to-Policy Interface

By Dominique Kone, Masters Student in Marine Resource Management

How can I practice conservation? As an early-career professional and graduate student, this is the very question I ask myself, constantly. In such an interdisciplinary field, there are several ways someone can address issues and affect change in conservation, even if they don’t call themselves a conservationist. However, there’s no one-size-fits-all method. A marine ecologist will likely try to solve a problem differently than a lawyer, advocate, journalist and so forth. Therefore, I want to explain how I practice conservation, how I develop solutions, and how this has factored into my decision to come to grad school and apply my trade to our sea otter project.

Like many others in conservation, I have a deep appreciation for the field of ecology. Yet, I also really enjoy being involved in policy and management issues. Not just how they’re decided upon, but what factors and variables go into those decisions, and ultimately how those choices impact the marine environment. But most importantly, I’m curious about how these two arenas – science and policy – intersect and complement each other. Yet again, there are an endless number of ways one can practice conservation at the science-policy interface.

Think of this science-policy space as a spectrum or a continuum, if you will. For those who fall on one end of the spectrum, their work may be heavily dominated by pure science or research. While those who fall on the other end, conduct more policy-oriented work. And those in the middle do some combination of the two. Yet, what connects us all is the recognition of the value in science-based decision-making. Because a positive conservation result relies on both elements.

I’m fascinated by this science- policy space and the role that science can play in informing the management and protection of at-risk marine species and ecosystems. From my perspective, scientific evidence and the scientific community are essential resources to help society make better-informed decisions. However, we don’t always take advantage of those resources. On the policy end of the spectrum, there may be a lack of understanding of complex scientific concepts. Yet, on the other end, scientists may be inadvertently making their research inaccessible or they may not fully understand the data or knowledge needs of the decision-makers. Therefore, research that was meant to be useful, sometimes completely misses the mark, and therefore has minimal conservation impact.

Recognizing this persistent problem, I practice conservation as a facilitator, where I identify gaps in knowledge and strategically develop science-based solutions aimed at filling those gaps and addressing specific policy or management issues. In my line of work, I’m dedicated to working within the scientific community to develop targeted research projects that are well placed and thought-out to enable a greater impact. While I associate myself with the science end of the spectrum, I also interact with decision-makers on the other end to better understand the various factors and variables considered in decisions. This requires me to have a deeper understanding of the process by which decision-makers formulate policies and management strategies, how science fits within those decision-making process, and any potential gaps in knowledge or data that need to be filled to facilitate responsible decisions.

A simple example of this is the use of stock assessments in the management of commercially important fisheries. Catch limits may seem like simple policies, but we often do not think about the “science behind the scenes” and the multitude of data needed by managers to set those limits. Managers must consider many variables to determine catch limits that will not result in depleted stocks. Without robust scientific data, many of these fisheries catch limits would be too high or too low.

This may all sound like theoretical mumbo jumbo, but it is real, and I will apply this crossover between science and policy in my thesis. The potential reintroduction of sea otters to Oregon presents a multitude of challenges, but the challenge is exactly why I came to grad school in the first place! This project will allow me to take what I’ve learned and develop research questions specifically aimed at providing data and information that managers must consider in their deliberations of sea otter reintroduction. In this project I will be pushed to objectively assess and analyze – as a scientist – a pressing conservation topic from a variety of angles, gain advice from other experts, and develop and execute research that will influence policy decisions. This project provides the perfect opportunity for me to exercise my creativity, allow my curiosity to run rampant, and practice conservation in my own unique way.

Everyone processes and solves problems differently. For those of us practicing conservation, we each tackle issues in our own way depending on where we fall within the science-to-policy spectrum. For me, I address issues as a scientist, with my techniques and strategies derived from a foundation in the political and management context.

We Are Family

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

The GEMM Lab celebrating Leigh’s birthday with homemade baked goods and discussions about science.

A lab is a family. I know there is the common saying about how you cannot choose your family and you can only choose your friends. But, I’d beg to differ. In the case of graduate school, especially in departments similar to OSU’s Fisheries and Wildlife, your lab is your chosen family. These are the people who encourage you when you’ve hit a roadblock, who push you when you need extra motivation, who will laugh with you when you’ve reached the point of hysteria after hours of data analysis, who will feed you when you’re too busy to buy groceries, and who will always be there for you. That sure sounds a lot like a family to me.

Many of us spend weeks—if not months—conducting field research for our various projects. None of us do this work from the main campus…seeing as the main campus for Oregon State University is located Corvallis, Oregon which is approximately 50 miles inland from the Pacific Ocean. The GEMM Lab isn’t actually based on the main campus; instead, you’ll find the lab at the Hatfield Marine Science Center in Newport, Oregon, within a two-minute stroll of the picturesque Yaquina Bay. However, many of the core classes we need are only offered on main campus. This results in the GEMM Lab members being spread across Corvallis, Newport, and the dominant fieldwork site for their project (which could be locally in Oregon, or in the waters off of New Zealand). So rather than your typical, weekly, hour-long lab meetings, the GEMM Lab meetings are monthly and last on the order of 3-5 hours. Others hear this and think that must be overwhelming to have such a long lab meeting. On the contrary, these are scheduled to fit into all of our chaotic schedules. One day a month, all of us gather together as a family unit, share what’s new about our lives, be sounding boards for each other, solve problems, and do so in a supportive environment. Hopefully you’re getting the picture that just because we’re all part of the same lab, it doesn’t mean we’re geographically close. This is exactly why we cultivate meaningful relationships while we are together. The Harvard Business Review published an article 2015 based on multiple peer-reviewed journals, summarizing the six dominant characteristics necessary to foster a positive workplace:

Caring for colleagues as friends
Supporting each other
Avoiding blame and forgiving mistakes
Inspiring each other at work
Emphasizing the meaningfulness of the work
Treating each other with respect

And I can attest that every member within the GEMM Lab embraces all of these characteristics and I have a feeling that none of them have read that article prior to today. Family naturally follows those basic guidelines. And, our lab, is a family.

Case and Point: when I was applying for graduate programs, I made a point of traveling to meet the GEMM Lab members at the monthly lab meeting. Sure, I also wanted to make sure that both Newport and Corvallis would be good fits in terms of locations. But, mostly, I needed to see if this Lab would be a strong family unit for my graduate school career and beyond. The moment I arrived at Hatfield Marine Science Center in Newport, it was clear, this was a family that I could see myself being a part of. Not only had all the members brought some kind of food item to share at the lab meeting (this was important to me), but Florence had baked homemade bread, Dawn had offered to show me around Hatfield, and Leila had set up a time to take me around main campus with other grad students. During the lab meeting discussions, I was welcomed to contribute and I felt comfortable doing so. That was another big moment where something “clicked” and I knew I had found a great group of amazing scientists who were also amazing human beings.

Flash forward a few months, and now I am one of those lab members who is bringing food to lab meetings. More than that, we have GEMM Lab dinners and game nights. I may be based in Corvallis, but I commute out to Newport just for these fun activities because this is my family. I want to be with them—not only when we’re talking about our research—but when we’re laughing about the silly things that happen in our daily lives, comically screaming at each other in an effort to win whatever game is on the table, and enjoying home-cooked meals. This is my family.

I guess I’d like to plug this message to any potential graduate student regardless of discipline(s): find a lab with people that you truly want to surround yourselves with—day and night—in good times and in bad times—because undoubtedly, you’ll need those kinds of people. And, to current lab constituents in any lab: it’s up to us to create a supportive family which will make everyone successful.

Sister Sledge knew just this when the group sang this verse of their hit, “We Are Family”:

Living life is fun and we’ve just begun
To get our share of this world’s delights
High, high hopes we have for the future
And our goal’s in sight
We, no we don’t get depressed
Here’s what we call our golden rule
Have faith in you and the things you do
You won’t go wrong, oh-no
This is our family Jewel

I’m grateful to have found a lab that embodies the lyrics of one of my favorite childhood karaoke songs. The GEMM Lab is not only a lab that produces cutting-edge science; it is a family that encourages one another in all facets of life—creating an environment where people can have high-quality lives and generate high-quality science.

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!

Exploring the Coral Sea in Search of Humpbacks

By: Solène Derville, Entropie Lab, Institute of Research for Development, Nouméa, New Caledonia (Ph.D. student under the co-supervision of Dr. Leigh Torres)

Once again the austral winter is ending, and with it ends the field season for the scientific team studying humpback whales in New Caledonia. Through my PhD, I have become as migratory as my study species so this is also the time for me to fly back to Oregon for an intense 3 months of data analysis at the GEMM Lab. But before packing, it is time for a sum-up!

In 2014, the government of New Caledonia has declared all waters of the Economic Exclusive Zone to be part of a giant marine protected area: the Natural Park of the Coral Sea. These waters are seasonally visited by a small and endangered population of humpback whales whose habitat use patterns are poorly known. Indeed, the park spans more than 1.3 million km² and its most remote and pristine areas therefore remained pretty much unexplored in terms of cetacean presence… until recently.

In 2016, the project WHERE “Humpback Whale Habitat Exploration to improve spatial management in the natural park of the CoRal Sea” was launch by my PhD supervisor, Dr. Garrigue, and I, to conduct surveys in remote reefs, seamounts and shallow banks surrounding New Caledonia mainland. The aim of the project is to increase our understanding of habitat use and movements of humpback whales in breeding grounds over a large spatial scale and predict priority conservation areas for the park.

Fig. 1. A humpback whale with our research vessel, the oceanographic vessel Alis, in the background.

This season, three specific areas were targeted for survey during the MARACAS expeditions (Marine Mammals of the Coral Sea):

– Chesterfield and Bellona reefs that surround two huge 30- to 60m-deep plateaus and are located halfway between New Caledonia and Australia (Fig. 4). Considered as part of the most pristine reefs in the Coral Sea, these areas were actually identified as one of the main hotspots targeted by the 19^th century commercial whaling of humpback whales in the South Pacific (Oremus and Garrigue 2014). Last year’s surveys revealed that humpback whales still visit the area, but the abundance of the population and its connection to the neighboring breeding grounds of New Caledonia and Australia is yet to establish.

Fig. 2. The tiny islands along the Chesterfield and Bellona reefs also happen to host nesting sites for several species of boobies and terns. Here, a red-footed booby (Sula sula).

– Walpole Island and Orne bank are part of the shallow areas East of the mainland of New Caledonia (Fig. 4), where several previously tagged whales were found to spend a significant amount of time. This area was explored by our survey team for the first time last year, revealing an unexpected density of humpback whales displaying signs of breeding (male songs, competitive groups) and nursing activity (females with their newborn calf).

Fig. 3. The beautiful cliffs of Walpole Island rising from the Pacific Ocean.

Antigonia seamount, an offshore breeding site located South of the mainland (Fig. 4) and known for its amazingly dense congregations of humpback whales. The seamount rises from the abyssal seabed to a depth of 60 m, with no surfacing island or reef to shelter either the whales or the scientists from rough seas.

Fig. 4. Map of the New Caledonia Economic Exclusive Zone (EEZ) and the project WHERE study areas (MARACAS expeditions).

During our three cruises, we spent 37 days at-sea while a second team continued monitoring the South Lagoon breeding ground. Working with two teams at the same time, one covering the offshore breeding areas and the other monitoring the coastal long-term study site of the South Lagoon, allowed us to assess large scale movements of humpback whales within the breeding season using photo-ID matches. This piece of information is particularly important to managers, in order to efficiently protect whales both within their breeding spots, and the potential corridors between them.

So how would you study whales over such a large scale?

Well first, find a ship. A LARGE ship. It takes more than 48 hours to reach the Chesterfield reefs. The vessel needs to carry enough gas necessary to survey such an extensive region, plus the space for a dinghy big enough to conduct satellite tagging of whales. All of this could not have been possible without the Amborella, the New Caledonian governement’s vessel, and the Alis, a French oceanographic research vessel.

Second, a team needs to be multidisciplinary. Surveying remote waters is logistically challenging and financially costly, so we had to make it worth our time. This season, we combined 1) photo-identification and biopsy samplings to estimate population connectivity, 2) acoustic monitoring using moored hydrophone (one of which recorded in Antigonia for more than two months, Fig. 5), 3) transect lines to record encounter rates of humpback whales, 4) in situ oceanographic measurements, and finally 5) satellite tracking of whales using the recent SPLASH10 tags (Wildlife Computers) capable of recording dive depths in addition to geographic positions (Fig. 6).

Fig. 5. Claire, Romain and Christophe standing next to our moored hydrophone, ready for immersion.

Satellite tracks and photo-identification have already revealed some interesting results in terms of connectivity within the park and with neighboring wintering grounds.

Preliminary matching of the caudal fluke pictures captured this season and in 2016 with existing catalogues showed that the same individuals may be resighted in different regions of the Park. For instance, some of the individuals photographed in Chesterfield – Bellona, had been observed around New Caledonia mainland in previous years! This match strengthens our hypothesis of a connection between Chesterfield reef complex and New Caledonia.

Yet, because the study of whale behavior is never straightforward, one tagged whale also indicated a potential connection between Chesterfield-Bellona and Australia East coast (Fig. 6). This is the first time a humpback whale is tracked moving between New Caledonia and East Australia within a breeding season. Previous matches of fluke catalogues had shown a few exchanges between these two areas but these comparisons did not include Chesterfield. Is it possible that the Chesterfield-Bellona coral reef complex form a connecting platform between Australia and New Caledonia? The matching of our photos with those captured by our Australian colleagues who collected data at the Great Barrier Reef in 2016 and 2017 should help answer this question…

Fig. 6. “Splash” was tagged in Chesterfield in August and after spending some time in Bellona it initiated a migration south. Seamounts seem to play an important role for humpback whales in the region, as “Splash” stopped on Kelso and Capel seamount during its trip. It reached the Australian coast a couple of days ago and we are looking forward to discover the rest of its route!

While humpback whales often appear like one of the most well documented cetacean species, it seems that there is yet a lot to discover about them!

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!

With all that being said, be sure to follow us on: Twitter, YouTube, and here (don’t forget to follow us by entering your email address on the lefthand side of the page), of course.

New steps towards community engagement: introducing high schoolers to the field

By Florence Sullivan, MSc, GEMM Lab Research Assistant

This summer, I had the pleasure of returning to Port Orford to lead another field season of the GEMM Lab’s gray whale foraging ecology research project. While our goal this summer was to continue gathering data on gray whale habitat use and zooplankton community structure in the Port Orford region, we added in a new and exciting community engagement component: We integrated local high school students into our research efforts in order to engage with the local community to promote interest in the OSU field station and the research taking place in their community. Frequent blog readers will have seen the posts written by this year’s interns (Maggie O’Rourke Liggett, Nathan Malamud, and Quince Nye) as they described how they became interns, their experience doing fieldwork, and some lessons they’ve learned from the project. I am very impressed with the hard work and effort that all three of them put into making this field season a success. (Getting out of a warm bed, and showing up at the field station at 6am sharp for five weeks straight is no easy feat for high-schoolers or an undergrad student during summer break!)

During the month of August, our team collected the following data on whale distribution and behavior:

Spent 108 hours on the cliff looking for whales
Spent 11 hours actively tracking whales with the theodolite
Collected 19 whale tracklines
Identified 15 individual whales using photo-ID – Two of those whales came back 3 times each, and one of them was a whale nick-named “Buttons” who we had tracked in 2016 as well.

We also collected data on zooplankton – gray whale prey – in the area:

Collected 134 GoPro videos of the water column at the 12 kayak sample sites
Did approximately 147 zooplankton net tows
Collected 64 samples for community analysis to see what species of zooplankton were present
Collected 115 samples for energetic analysis to determine how many calories can be derived from each zooplankton

Since I began this project in 2015, I have been privileged to work with some truly fantastic interns. Each year, I learned new lessons about how to be an effective mentor, and how to communicate our research goals and project needs more clearly. This year was no exception, and I worked hard to bring some of the things I’ve learned into my project planning. As the team can tell you, science communication, and the benefits of building good will and strong community relationships were heavily emphasized over the course of the internship. Everyone was encouraged to use every opportunity to engage with the public, explain our work, and pass on new things they had learned. Whenever the team encountered other kayakers out on the water, we took the time to share any cool zooplankton samples we gathered that day, and explain the goals of our research. Maggie and I also took the opportunity to give a pair of evening lectures at Humbug Mountain State Park, which were both well attended by curious campers.

In addition, the team held a successful final community presentation on September 1 at the Port Orford Field Station that 45 people attended! In the week leading up to the presentation, Quince and Nathan spent many long hours working diligently on the powerpoint presentation, while Maggie put together a video presentation of “the intern experience” (Click here for the video showcased on last week’s blog). I am incredibly proud of Nathan and Quince, and the clear and confident manner in which they presented their experience to the audience who showed up to support them. They easily fielded the following questions:

Q: “How do you tell the difference between a whale that is searching or foraging?”

A: When we look at the boundaries of our study site, a foraging whale consistently comes up to breathe in the same spot, while a searching whale covers a lot of distance going back and forth without leaving the general area.

Q: “How do we make sure that this program continues?”

A: Stay curious and support your students as they take on internships, support the field station as it seeks to provide resources, and if possible, donate to funds that raise money for research efforts.

When communicating science, it is important to results into context. In addition to showcasing the possibilities of excellent research with positive community support, and just how much a trio of young people can grow over the course of 6 weeks, this summer has highlighted the value of long term monitoring studies, particularly when studying long-lived animals such as whales. We saw far fewer whales this summer than compared to the two previous years, and the whales spent much less time in the Port Orford area (Table 1). As a scientist, knowing where whales are not (absence data) is just as important as knowing where whales are (presence data), and these marked differences drive our hypotheses! What has changed in the system? What can explain the differences in whale behavior between years? Does it have to do with food quality or availability? (This is why we have been gathering all those zooplankton samples.) Does it have to do with other oceanographic factors or human activities?

Table 1. Summary of whale tracking efforts for the three seasons of field work in Port Orford. Notice how in 2017 we only collected 194 whale location points (theodolite marks). This is about 92% less than in the previous years.

	2015	2016	2017
Hours spent watching	72:49	148:30	108
Hours spent tracking	80:39*	82:30	11
Number of individuals	43	50	15
Number of theodolite marks	2483	2414	194

*we often tracked more than one individual simultaneously in 2015

Long term monitoring projects give us a chance to notice differences between years, and ask questions about what are normal fluctuations in the system, and what are abnormal. On top of that, projects like this create the opportunity for additional internships, and to mentor more students in the scientific method of investigation. There is so much still to be explored in the Port Orford ecosystem, and I truly hope this program is able to continue. If you are interested in making a monetary contribution to sustain this research and internship program, donations can be accepted here (gemm lab fund) and here (field station fund).
