Everything’s bigger in Texas, even shark research!

Jonathan Davis is a marine biologist, shark researcher, and Fish and Wildlife Tech for the Texas Parks and Wildlife Department based out of Sabine Lake, Texas. He has researched elasmobranchs for over 10 years all around the world from New Zealand to Australia and along the U.S. coast from Massachusetts to Texas. Currently, he is continuing research as part of his PhD along the Texas coast focusing on bull shark ecology. In addition to research, Jonathan does outreach to inform the general public about sharks and inspire interest rather than fear to promote conservation rather than destruction.

This year marks the 27^th Shark Week. For the past 27 years, Discovery Channel has had the unrivaled and incomparable attention of the world for one week in regards to all things ‘shark’. These 27 years have brought out the best in shark science in the beginning but have sadly declined by bringing out the worst in fear-mongering and sensationalist misinformation more recently. As a shark scientist who grew up watching Shark Week for the science the last several years have been disheartening to say the least. The science seemed to all but disappear and replaced by completely inaccurate information, scary attacks that never happened, and an epidemic of Megalodon sized proportions. Not to mention the fact that my lifelong dream of being on Shark Week was fulfilled only to have my research superimposed into a show about a ridiculous mythical shark #VoodooShark. In the midst of all these years of Shark Week, real shark science has been increasing and advancing. Sharks are an integral part of our ecosystems but many are endangered and in need of conservation. This is why shark scientists work in the background to learn as much as possible about these creatures that spark such awe and interest worldwide, not to feed fear-mongering and sensationalist desires of money hungry producers. With that being said, it would behoove all of us to utilize the unparalleled platform that is Shark Week to spread correct information and promote shark conservation.

Does Shark Week portrayal of sharks matter?

I’ve been critical of factual inaccuracy and fearmongering on Shark Week documentaries for years. But how big of a problem is this, and how do we know? I asked some of the authors of three recent scientific studies* to summarize the evidence.

Many species of sharks are in desperate need of conservation. Twenty-four percent of all known species of sharks, skates and rays are considered Threatened with extinction by the IUCN Red List. Using a variety of different methods, scientists have documented rapid and severe population declines in many species of sharks all over the world.

Conservation requires public support. In a participatory democracy, new policies and regulations require some public support to pass. It’s easy to get public support to conserve cute and cuddly animals, but ugly animals need protection too. So do animals that scare people, like sharks.

Three facts (and a lot of questions) about The Ocean Cleanup

Conservation, Science

The Ocean Cleanup is back in the news, with their first test deployment happening imminently off the coast of Japan. From reviews of their current material, it seems clear that they have not taken the critical assessment of their feasibility study, graciously provided pro-bono by Drs. Martini and Goldstein, to heart. This is unfortunate. As the project has progressed, many in the ocean science and conservation community have not only grown more skeptical of its effectiveness, but are increasingly wary of the potential this project has to cause significant environmental harm. As of yet, The Ocean Cleanup has presented no formal Environmental Impact Assessment, a critical document which would provide the data necessary to properly gauge the potential for environmental harm from large-scale engineering projects.

Goldstein and Martini’s technical review is essential reading for anyone tracking the progress of The Ocean Cleanup, but there are many additional issues that the Ocean Cleanup has not yet addressed. Here, I present three issues related to the construction and operation of The Ocean Cleanup and the necessary information that, were I in charge of regulating the high seas, would need to know before such a project could be approved.

1. The Ocean Cleanup will be the largest offshore structure ever assembled.

When completed, The Ocean Cleanup will span 100 km of open sea with a massive array of booms and moored platforms. If successfully constructed in the proposed region, the mooring used will be the deepest ever constructed. The booms will stretch across a major oceanic current, interacting with plankton transport and pelagic migrations.

What I want to know: How will The Ocean Cleanup monitor changes in ocean-wide population structure? What community baselines have been established from which ecosystem impact can be assessed? What contingency are in place should catastrophic failure occur? Ultimately, what chronic threshold will be used to trigger a shutdown of the Ocean Cleanup, should major environmental impacts be detected as a result of standard operation, who will access to the data necessary to monitor those impacts, and who will have authority to trigger a shutdown?

A poster to remember

Today I was at an undergraduate research event with our best and brightest presenting their research via posters – great science, but often dreadful posters.

Posters can be a great medium for getting your science over to an audience. They have the benefit that if you can draw people into your poster you can have a lot more intimate face to face discussion with your peers. But first you have to draw them in…

Increasingly poster sessions in conference are becoming large sprawling events, and your poster is going to have to compete for attention with hundreds if not thousands of other posters, with your audience having little time to browse, they may be distracted by friends and colleagues, they may be tired as poster sessions are often at the end of a long day of presentations, and possibly (probably) slightly to moderately drunk. Here are some simple tips for making a good poster that has impact.

From Sea and Sky: Hacking the Chesapeake with #BayBots

Conservation, Science

Two years ago, I moved to San Francisco. It was… an experience. I had the opportunity to meet some incredible technologists, leaders in the emerging world of citizen exploration, and developers, coders, and makers using their skills and expertise to help save the environment. I met some amazing drone builders developing platforms and tools to measure the world. I also learned that West Coast living was not for me. The southern Atlantic coast called me back. But before I left, I led a small team across the Pacific to Papua New Guinea, where we taught undergraduates from the University of Papua New Guinea and the University of the South Pacific how to build and operate OpenROVs and incorporate them into marine ecology research.

The West Coast was good to me. It helped refine my vision for bringing low-cost, open-source technologies into the marine science and conservation world. Citizen science is becoming increasingly important, and the need for both democratizing and decolonizing science will drive much of the evolution of the scientific community in the 21st century. Tools that are effective, cheap, and open-source will play a major role in this transition. I returned east and began planning the next phase of this vision.

The Chesapeake Bay (San Franciscans take heed, you can keep your “Area” but “The Bay” will always be the Chesapeake) is the largest estuary in the United States, is economically important for shipping, fisheries, and tourism, and also happens to be the body of water that I grew up on. I learned to swim, fish, sail, and motor in one of the Bay’s many tributaries. It’s also home to more than a dozen research institutes, which work, sometimes in coordination and sometimes not, on studying and protecting the Bay.

What happens when we punch a hole in the seafloor?

A longtime submariner I know tells the story of a most unusual dive. On this particular plunge, they went down into the briny deep to place what can best be described as a giant manhole cover on the seafloor. There was a hole, and, by all accounts, the sea was draining in to it.

For more than half-a-century, we’ve been drilling holes in the bottom of the sea. Some reveal the buried history of the evolution of our oceans. Others uncover vast wells of crude oil. Science, exploration, and exploitation have all benefited from ocean drilling programs. But what happens to the seafloor when you punch a hole in the ocean? In my friend’s case, the drilling program opened a sub-sea cavern, resulting in changes to local current regimes, potentially disturbing the surrounding benthic community. The most practical solution was to simply plug the hole.

We’ve punched a lot of holes in the seafloor, but despite a few anecdotes and scant research, we know precious little about how these holes actually alter the marine environment. This is particularly worrying, as deep-sea mining at hydrothermal vents, manganese nodule fields, and oceanic crusts are slowly creeping out of the realm of science fiction and into our oceans. Ocean drilling in the deep sea is perhaps the closest analog to industrial-scale deep-sea mining. Understanding the potential impacts is critical to designing management and mitigation regimes that protect the delicate deep seafloor.

You say you need to incorporate the social sciences? Which kind?

This post in the second of a series entitled “The Basics of the Human Dimensions”, which gives the most basic tips for how to work with social scientists and social questions in marine conservation efforts. Whether you are the stakeholder, the collaborating natural scientist, or both, this series will hopefully make the journey into the human dimensions easier.

A common adage in fisheries management is that “you’re managing the fishermen, not the fish” – and this is emblematic of many conservation issues. Conservation efforts rely upon good information (which also requires diverse inputs, but that’s a story for another day) but perhaps most importantly, understanding how decision-makers will use that information and how communities will integrate that information into their daily practices. Conservation is a lived experience, not theory in a textbook.

As a response to an awakening in the ecological sciences to this paradigm, there are frequent calls for integrating the social sciences into their analyses. A program within the National Science Foundation directs research dollars to “Coupled Human and Natural Systems”, the Resilience Alliance is pushing the theory of socioecological systems, and out of geologists comes the term “anthropocene” – all efforts to formally incorporate social scientists into traditionally natural science research efforts. But not all social sciences are created equal. Which one you need depends upon your subject matter, but also the kind of data that will mesh best with your natural science methods. Here’s a quick review of the disciplinary divides within the social scientist, so you have an idea of who best to reach out to in putting together your next proposal:

Become a Citizen Scientist with SharkBase

Dr. Ryan Kempster is a shark biologist in the Neuroecology Group at the University of Western Australia. Ryan founded the shark conservation group Support Our Sharks to inform the world about the plight of the most vulnerable shark species. His research focuses on the sensory biology and conservation of sharks and rays. Sharks have always been his passion, and protecting them his goal. To do this, Ryan has embarked on a career in research to better understand sharks. He takes every opportunity to communicate his findings to the general public in the hope that he can inspire others to follow in his passion for protecting these amazing animals.

Effective management of sharks starts with an understanding of their population status, which ultimately instructs their future conservation. Unfortunately, many shark species are at significant risk of unrecoverable decline, with some species having declined to near extinction in recent years. We believe that Citizen Science could hold the key to improving our understanding and management of shark populations, whilst also advancing community education. This is why we have developed SharkBase, a global shark encounter database helping to map the distribution and population structure of sharks worldwide (you can also record ray and skate sightings).

Last week, we launched a novel little experiment in crowdfunding marine science and conservation – Buy David Shiffman a Less Ugly Pair of Sunglasses – ostensibly about replacing David’s legendarily hideous sunglasses with something a bit more aesthetic. Of course, anyone digging into the stretch goals quickly realized that this was less about sunglasses and more about funding some cool research and outreach projects we’re currently working on; projects like a hammerhead conservation genetics analysis, building a marine ecology drone, and sending students from underserved schools of a shark tagging trip. This was made more explicit when we hit our first goal in the first 36 hours of funding.

With the first funding goal achieved, I decided we needed a cool perk, something not particularly expensive to produce but completely novel and cool enough to justify making a heftier donation. And, of course, it needed to be thematically related to the spirit of the project.

Enter the Megalodon.

Science Flyers: My comment to the FAA regarding proposed new drone regulations.

April 8, 2015April 8, 2015 Andrew Thaler

Science

I submitted the following to the FAA regarding docket number FAA-2015-0150: Operation and Certification of Small Unmanned Aircraft Systems. Comments can be filed online, but I also sent an actual, physical letter. If you care about the regulation of drone in US airspace, you have until April 24, 2015 to submit you own.

I am a marine ecologist based in Virginia, with plans to operate small Unmanned Aircraft Systems in the conduct of marine ecologic research.

With regards to the FAA’s recently proposed regulations for the Operation and Certification of Small Unmanned Aircraft Systems, I find that the vast majority of suggested restrictions and requirements to be both reasonable and not particularly onerous for those wishing to operate UAS’s for commercial purposes. I commend the FAA for taking a pragmatic approach to UAS regulation. In particular, I support the requirement for a comprehensive knowledge test, which will be separate from and less expensive than a full pilot’s license. I also appreciate the recognition that UAS technology is advancing so quickly that a certification of airworthiness for specific airframes will place an undue burden on commercial pilots and force them to operate vehicles several generation behind the state of the art. I also approve of a special exemption for “microdrones”, which have significantly a lower safety risk and allow UAS pilots additional freedom in their use of very small vehicles.

I approve of the requirement that operators maintain visual line-of-sight, however, in the proposed regulations, there are make no provisions for autonomous flight. Autonomous flight dramatically changes the relationship between the aircraft and the operator and is an essential component of ecological surveys, allowing drones to fly straight transects and pinpoint sampling sites. This points to a more specific problem with the proposed regulations: in current form, there is little clarity regarding the role of scientists and other researcher in relation to UAS use. Will ecologists fall under the same restrictions as commercial drone pilots, or will they be treated more similar to hobbyist?

I urge the FAA to adopt a “Science Flyer” certification, similar to the American Association of Underwater Scientists “Science Diver” program. To wit, science divers have enhanced training requirements over recreational SCUBA divers, but less than professional commercial divers. A Science Flyer program could span a similar gap, with more training requirements than a hobbyist but fewer restrictions than a commercial UAS operator and could also provide additional training and certification to allow for autonomous operation.
