Matt Kolmann is a PhD candidate whose research program is at the interface of evolution, comparative anatomy, and biomechanics. He completed his Master’s degree at Florida State University with Dr. Dean Grubbs on the feeding biomechanics and fisheries ecology of cownose rays, a purported pest on commercial shellfish. During this process he developed a love of field work, and since then has collected rays and other fishes on expeditions across South and Central America with the Royal Ontario Museum. His PhD research investigates the evolution of biodiversity using South American freshwater stingrays as a model system. The number of different feeding niches these stingrays occupy is astounding, and Matt is using gene-sequencing, comparative phylogenetic methods, and biomechanical modeling to characterize the evolutionary processes underlying this biodiversity. From June 8th through the end of Shark Week, he will be raising funds to delve more deeply into the evolution of feeding behavior in freshwater rays – specifically investigating whether freshwater rays ‘chew’ tough prey like insects in a manner comparable to mammals. Follow him on twitter!

What role does our food have in explaining where we live, what we look like, and how we behave? I study how properties of prey – material, structural, and ecological – shape the evolution of predators. Specifically, I am interested in how animals adapt to novel foods and diets that pose unique challenges: prey that are tough, stiff, hard, or just generally robust. I approach these questions at the macroevolutionary (how species are related) level; biodiversity lends insight into engineering and synthetic design based on an understanding of how animals evolve using similar organic principles.

Help crowdfund shark research: Quick(silver?) stingrays

Kady Lyons is a Ph.D. candidate whose research focuses on the intersection of physiology, ecology and toxicology. Her Master’s at Cal State Long Beach with Dr. Chris Lowe got her involved in elasmobranch toxicology. She is interested in how elasmobranchs respond to anthropogenic contaminants and how contaminants can be used as another tool to study ecology. Currently, her Ph.D. is examining how accumulation of these man-made contaminants influences round stingray growth and reproduction. As part of her Master’s work, she began to investigate mercury accumulation and body distribution of mercury, a potent neurotoxin, in elasmobranchs using the round stingray as a model species. She is continuing to work on this project and will be raising funds to finish this research as part of The Experiment’s Sharks Grant Challenge beginning June 8th and running through the Discovery Channel’s Shark Week.

Mercury concentrations in the earth’s atmosphere have significantly increased with human activities such as mining and fossil fuel burning. Mercury can be transformed into its more dangerous form (methylmercury) and this form is what becomes concentrated in animals’ tissues. For animals that occupy higher positions in the food web such as elasmobranchs (sharks, skates and rays), mercury can bioaccumulate to high levels due to their long life and carnivorous behavior.

Trading blue collars for scarlet robes, my working-class experience of academic life

June 9, 2016 Michelle Jewell

Academic life, Science

More people are going to college, graduate school, and obtaining PhDs in STEM fields than ever before (Figure 1), and a growing minority of these PhD candidates are non-traditional or not white affluent males. While we celebrate this change, let us not forget that academia was built by – and for – the “traditional” student. My favourite analogy to explain this type of ingrown privilege is bicycles on USA streets. Bicycles are legally allowed to be on streets, some streets even have extra space just for bicycles, but streets were designed for automobiles. You may be allowed and, in some areas, encouraged to get on the street with your bicycle, but biking a street is going to be intrinsically more difficult than if you were driving a car.

Like Marconi and La Bamba in a city built on rock and roll, you will inevitably end up in situations that conflict with your way of life. You will not receive a warning before you stumble upon these bumps, and you will be judged by how quickly you accept traditional standards (if you can). I remember a conversation with traditional tenured and tenure-track scientists discussing proposals for a large grant scheme. One tenure-track scientist was lamenting the process of shopping for editors for his proposal. He talked about it freely, how there were two companies that charged different rates and he was in talks with one but that company felt a conflict of interest that he had worked with another rival editing company. The rest of the traditional scientists nodded in mutual understanding. Finding good, cheap editors to improve your work is hard. My working-class ethos was busy screaming inside my head. How can hiring someone to edit and improve written works that you will ultimately be rewarded for be so blithely acceptable? You’re not allowed to hire editors for any task throughout your training. You learn how to write from earning disappointing grades (or failing grant applications). You read more, you study written works, you develop a voice, and you try again. The results get better until you are at an appropriate level to move up another notch on the ladder, right? Not for traditionals.

Here are some more bizarre “traditional” customs you should expect if you are biking down the academic street:

Fun Science FRIEDay – The worlds largest sponge.

Recently a team of scientists on a deep sea expedition in the Northwestern Hawaiian Islands aboard the R/V Okeanos Explorer made a monumental discovery… pun intended. While exploring the depths of the seafloor in Papahānaumokuākea Marine National Monument, with their remotely operated vehicles (ROV) Seirios and Deep Discover, they discovered and documented the largest sponge ever observed on this planet… or any planet for that matter.

Six thoughts about Greenpeace’s attack on Ray Hilborn.

May 13, 2016June 2, 2016 Andrew Thaler 6 Comments

Conservation, Science

Update: Both the University of Washington and the Proceedings of the National Academy of Sciences have reviewed Greenpeace’s claims and concluded that Hilborn did not violate their disclosure policy.

First, some background:

Or, just read Trevor Branch’s timeline.

1. The idea that scientists should declare every source of funding over the history of their career on every scientific paper is impractical and wholly unnecessary in a connected world where anyone can effortlessly access a researcher’s CV. Non-profit NGOs only need to file one financial disclosure statement every year, not attach it to every press release, and that is also perfectly adequate.

2. Transparency in funding is important. Claiming that a researcher is failing to disclose funding information when that information clearly is available and accessible erodes public trust in science and makes everyone’s job harder. Greenpeace didn’t send a team of stealth lawyers on an o’dark thirty raid of the UW mainframe, they asked for the information and were given it.

Julia Wester is the Director of Program Development for Field School. She received her PhD from the Abess Center for Ecosystem Science and Policy at the University of Miami in 2016. Her dissertation studied the psychology of decision making about the environment, specifically with regard to limited water resources. She also received a Msc with Distinction in Biodiversity Conservation and Management from Oxford University and worked as a Legislative Aide in South Florida, focusing on environmental policy. She has consulted with nonprofit programs to evaluate their educational programs and assisted with training staff to conduct effective public outreach.

The folks at Southern Fried Science, as part of their commitment to research and education, have generously given us this platform to talk about our educational start-up, Field School. (Thanks, SFS!). They’ve also been kind enough to get excited about working with us to develop and test new research techniques, study awesome animals and ecosystems, and improve marine science field education—so stay tuned for some of those upcoming collaborations!

What is field school?

Field School is a hybrid company on a mission to support field research in marine and environmental science, and create high-quality educational and training opportunities for students and the public. We offer hands-on, research focused courses on a variety of topics, from corals to sharks, on our 55’ custom live-aboard research vessel.

Part of what makes Field School special is the team we’ve brought together. Our captain and crew all have doctoral and/or masters degrees in marine or environmental science, have authored numerous scientific publications, and have a combined 25 years of experience in field education and outreach. We have developed short- and long-term training and mentoring opportunities for students, teach highly reviewed and award-winning university courses, and work with partner non-profits to create outreach programs for the public. We collaborate closely with our scientific advisory board and partner universities to develop the conservation and research projects our students work on, ensuring their time in our courses is professionally relevant and meaningful.

The BeagleBox 2: a dirt-cheap, tough-as-nails, 3D-printed, versatile field laptop.

May 9, 2016May 12, 2016 Andrew Thaler

Science

Last year, as part of Oceanography for Everyone, we debuted the BeagleBox, a small, cheap, tough, basic field computer powered by a BeagleBone Black. The first BeagleBox didn’t promise much, it was designed for basic field work and, most importantly, to be cheap enough that researchers (particularly grad students) wouldn’t be too worried about damaging it. It wasn’t designed to be your only computer but to replace your more valuable computer when participating in fieldwork.

In the last year, the single board computer landscape has changed, with new systems running off tiny, powerful 64bit ARM chips. One of the first of this new breed of SCB to hit the market was the massively Kickstarted, and rocky-launching Pine64. I received my 1GB Pine64 late last week, and immediately set to work redesigning the BeagleBox to house this larger board (and correct for some other annoyances in the original design). So here it is, an even beefier, cheaper, tougher field machine.

Yes, it will run an OpenROV. It will not run it well.

Big ideas and little robots: Using the OpenROV in interdisciplinary STEM projects

Joey Maier is a biology professor at Polk State College where he uses every possible opportunity to encourage his students to spend time in the water, play with technology, and do #CitizenScience. As an undergraduate, he did a stint as an intern for Mark Xitco and John Gory during their dolphin language experiments. He then spent the years of his M.Sc. at the University of Oklahoma thawing out and playing with bits of decaying dolphin. After discovering that computers lack that rotten-blubber smell, Joey became a UNIX sysadmin and later a CISSP security analyst.

While his pirate game is weak, he is often seen with a miniature macaw on his shoulder. His spare time is spent SCUBA diving and trying to hang out with people who have submersibles. You can follow him on Twitter or Facebook.

There’s a Klingon bird of prey hanging from the ceiling in my office.

I may teach biology, but at heart I’m a sci-fi nerd. Naturally, I’m interested in futurism, robots, lasers and all manner of techy paraphernalia. I’d been watching the OpenROV project for a while, but hadn’t gotten one yet. They were obviously awesome little machines that gave me a serious case of gadget envy, and I knew that some of our students would love to pilot an ROV. I needed a much better reason than that, however, to justify getting one. There’s no line item in our budget for, “Wow, that’s cool!” and I was fairly certain that the college administration would tend to favor lower cost and more familiar forms of student engagement

This tweet changed everything. When I found out that Andrew had designed a mini-Niskin bottle, the wheels in my head started turning. Assembling an OpenROV would, naturally, be a very STEM-oriented project. The times our students piloted the ROV could become water sampling field trips, and the kids could analyze their samples back at school as a laboratory activity. If students recorded the process, they could make a short film. I mulled over the possibilities and bounced ideas off of my dive buddies during the hours we spent traveling to and from the coast.

The Science of Aquaman: Understanding Dead Water

April 22, 2016April 23, 2016 Andrew Thaler

Popular Culture, Science

Update: legendary oceanographer Dr. Kim Martini stops by to set the record straight on the challenging subject of internal waves. Her comments in bold.

It has been a long time since I’ve made an entry into our long-running, world-famous, Science of Aquaman series. The last few runs have been heavy on high adventure, but light on ocean tidbits for me to nerd out on. I don’t like to force ocean fact into comic fiction unless the opportunity presents itself.

So, with the newest run of Aquaman, starting with issue #50, focusing around a villain named Dead Water, I thought it was the perfect moment to talk about some physical oceanography. And then…

My hat’s off to Dan Abnett, who beat me to the science punchline. If I had to explain the phenomenon of dead water in a single tweet, it would have been pretty close to this. Well played, sir. Well played.

So what is dead water and why does it make maneuvering a vessel so challenging?
