An insight into what Marine Mammal Observing is really like!

By Amanda Holdman

It’s August of 2015. That means I have exactly 2.5 months left until my field season and data collection for my masters comes to a close. At the end of October, I will have collected exactly 2 years of visual data on marine mammal distributions off of the coast of Newport, Oregon.

This is a bittersweet moment for me. Currently, I am on a 7 hour flight to Scotland to do some initial data analysis on my collected observations, with the help of a workshop offered by the University of St. Andrews. My first time abroad has me pretty restless with excitement on the plane, but with a 9 hour time change, some good rest will be key to being successful at the workshop. As I try to close my eyes, and picture what the next two weeks of what I like to call “Intensive Distance Sampling Summer School” will be like, the stranger next to me inevitably begins to make small talk, beginning with

“So what do you do?”

I usually tend to answer this question in two different ways. When I’m in my science community, I have no hesitation giving my 3 minute elevator speech on what I have been researching for the past year. However, when I’m making small talk with anyone I tend to just say

“I’m a master’s student studying marine mammals”

And that’s about all you need to say to get everyone’s attention around you! With a little more detail, I explain that I run transects to collect visual observation data of marine mammals to assist with understanding their patterns in distribution and habitat use. This explanation is always followed up with:

“Man, you’ve got the coolest job ever! What’s it like doing this all the time?”

Again most of the time I get this question, I’m usually conversing with people visiting the west coast hoping to see a large gray whale on vacation; or  young children who haven’t yet figured out that marine biology isn’t just about dolphins and pretty coral reefs – but it’s still good to inspire them! Just last week even, I ran into someone on the beach that told me his daughter thinks I’m a rock star for teaching her that you can research the sounds that whales, dolphins, and seals make. (His daughter attended Marine Science Day back in April, and I showed her some recordings of sounds – but I’ll carry this compliment with me for a long time)

But when people ask me how awesome my job is, I tend to keep the morale up and I usually answer

“yep, it’s pretty awesome. I love it! ”

But to be honest, sometimes… it isn’t.

For me, there are four components that equate to a great day of fieldwork: ocean conditions, marine mammals, the boat itself, and equipment (hydrophones, GPS, CTD, camera, etc.)

So in reality…

“The flow of research season goes a lot like this: whales are present, but ocean is impossible; or ocean is calm but the whales are gone; or both whales and ocean are good but the boat breaks down; or everything is working but the rain last night brought in some fog and ruined the visibility” (From Hawaii’s Humpbacks: Unveiling the Mysteries)

AND EVEN on the rare chance that everything goes right – observing marine mammals is hard and uncomfortable – 14 hours of standing with back pain, squinting into the sun until you see one part of the water that looks a little different than the others. I mean really there isn’t much on earth that’s more enormous than the ocean.

This sounds like a lot of negativity, but I am in Scotland currently to resolve some of these minor setbacks we encountered during field collection. Using a statistics program called DISTANCE, we can take into account environmental conditions, sea state, observer bias, etc. When we combine all of these factors together we create a detection function or a ratio of the animals we saw, compared to those we missed. Eventually we end up with an abundance estimate of how many animals are in our study area.

Analyzing the results of my observations this week has provided me with the realization that my time on a boat is coming to an end. In my two years of fieldwork collection, marine mammal observing has molded me into the type of person that has what it takes to do this kind of research: dedicated, tolerant to pain, boredom, and frustration, and most importantly passionate about what I am doing.

Passion is definitely a prerequisite for the life of a GEMM student. Graduate school gives you the chance to be reflective and the time to carefully wade through information. I’ve always had a strong desire to learn, and when I get to combine that with my personal interests, it turns out graduate school can be quite the rewarding initiative.

It’s easy to be discouraged sometimes, especially in an intense and competitive environment like scientific research. I can assure you though, even on our unlucky days, when we’ve swallowed all of the truths about the difficulties of what we do and we’re frustrated enough to give up, our luck turns – usually right when we need it to.

I think the BBC Zoologist, Mark Carwardine, knows just how I feel in saying, “There are few things more rewarding than seeing the worlds’s largest animal in its natural habitat!

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.

Surveying Harbor Porpoises on the Oregon Coast!

Hello Gemm lab readers!

Spring has officially made it to the Oregon coast.  The smells of blooming flowers are lingering in the air at the Hatfield Marine Science Center (HMSC), the seagulls are hovering around our afternoon BBQ’s, the local whale watching tour boats are zipping through the jetty’s to catch sight of all the whales still hovering in the area, and my team and I are right behind them as the field season is upon us in full force!

My name is Amanda Holdman and I am a master’s student in the Oregon State University’s Department of Fisheries and Wildlife and Marine Mammal Institute. Our lab, the geospatial ecology of marine megafuana, or GEMM lab for short, focuseharbor-porpoises_569_600x450s on the ecology, behavior and conservation of marine megafauna including cetaceans, pinnipeds, seabirds, and sharks. My research in particular is centered around the cetacean species that inhabit Oregon’s near coastal waters. While the cetacean order includes over 80 species, 30 of which can be found in Oregon, I am specifically targeting the small and charismatic harbor porpoise! I am hoping to answer questions about seasonal and diel patterns, and the drivers of these patterns to create a better understanding of the porpoise community off the coast of Newport.

To accomplish this, I have been using a couple different survey methods! Over the last year or so I have been conducting marine mammal visual surveys with a crew of observers, binoculars, cameras and lifejackets.  We’ve been very fortunate to work alongside and partner up with a number of labs and projects taking place at HMSC — including Sarah Henkel’s Benthic Ecology Lab, Jay Peterson’s Zooplankton Ecology Project, and Rob Suryan’s Seabird Oceanography Lab — who’ve invited us to share their boat time and join in on cruises to spot marine mammals. We had some motivating cruises with last year’s field season (bow riding pacific white sided dolphins and a possible fin whale sighting!) but now that the summer season is around the corner, It’s time to recruit additional observers and get everyone up to date on their safety certifications (at sea safety, first aid, etc.)

While we currently have about 6-8 boat trips a month, I am not only just looking  for harbor porpoises, I’m also listening for them. To complement the visual surveys, I’ve added an acoustic component to my research, with the help of the Oregon State Research Collective for Applied Acoustics lab (ORCAA). This allows me to survey for harbor porpoises even under the worst sea conditions, when boat trips are unavailable. Odontocetes, such as the harbor porpoise use echolocation to navigate and forage and can be identified acoustically by their frequency range. While a full-depth analysis of last summer’s data hasn’t yet been accomplished, I was able to take a quick peek and MAN IT LOOKS GOOD! Both harbor porpoise and killer whale vocalizations were identified – you can check out the spectrogram below! This combination of using visual and acoustic surveys will help us answer when the porpoises are in our near waters, and where there primary hang-outs are!

But springtime isn’t just for fieldwork, it’s also for course work! This quarter, my lab mate Erin Picket and I have enrolled into Julia Jones “Arcaholics anonymous” class, an introductory spatial statistics and GIS course that helps us piece together all the hard work we’ve put towards data collection to look for trends of animal distributions across space and time. This is the first time for both of us that we  get to upgrade our excel spreadsheets into a visual representation of our data! There will be more updates to come soon on how our projects are unfolding, but if you can’t wait til then, feel free to follow along with our class website!
