Deep-sea Researchers Support Nomination of the Marianas Trench Marine National Monument as a UNESCO World Heritage Site

Conservation

Early this December, the National Park Service announced that the Marianas Trench Marine National Monument made the short list for UNESCO World Heritage designation. Though hidden beneath the water’s surface, the Mariana Trench, a unique geologic and ecologic landmark and a natural treasure, dwarfs the Grand Canyon in scale and scope.

The Mariana Trench is more than a mile deeper than Mt. Everest is high and hosts Challenger Deep, the deepest point on Earth. It is also home to numerous sites of exceptional scientific value, including submerged volcanoes that host deep-sea hydrothermal vents, the largest documented mud volcanoes, coral atolls and fringing reef ecosystems that support apex predators like sharks and whales, as well as habitat-forming stony corals.

Fun Science FRIEDay – Harnessing Synthetic Biology to Fight Ocean Pollution

Conservation, Science

Plastics, more importantly microplastics, clog our oceans. This phenomena in the ocean has been likened to smog around cities. These plastic particles are dangerous because they can absorb toxins, subsequently be consumed by zooplankton and invertebrates, and bioaccumluate up the food web to fish that are consumed by humans. A study in Nature found that 25 percent of seafood sold contains microplastics! There has been a recent awareness of the unseen harm that exists when plastic pollution in the ocean degrades into microplastics. A report in Environmental Research Letters estimated that “accumulated number of micro plastic particles… ranges from 15 to 51 trillion particles, weighing between 93 and 236 thousand metric tons.” That is cray cray. Despite a better awareness of the impact of microplastics on marine ecology, we still have a poor spatial understanding of microplastics in the ocean. The presence and density of microplastics is determined by trawling the ocean (i.e., researchers go out with a net and physically count the pieces of plastic they pick up). As you can imagine, this is not very effective.

37 things I learned about shark ecology and conservation for my dissertation

The fam attending my dissertation defense

After a little more than 5 years of hard work, I’ve officially completed my Ph.D.! You can read my dissertation (“An Integrative and Interdisciplinary Approach to Shark Conservation: Policy Solutions, Ecosystem Role, and Stakeholder Attitudes”) online here in its entirety.

In case there are some among you who don’t really want to read a 281 page dissertation but are curious about what I found, I’ve prepared this blog post to summarize my key conclusions. (Note: this does not include every conclusion. Some are aggregated together, and some more technical conclusions are omitted for this summary).

Now, More Than Ever, America Needs an Ambassador for the Deep Sea.

That ambassador is Bathynomus giganteus, the giant, deep-sea isopod.

Conservation has long had the concept of Flagship Species—popular, charismatic species that serve as rallying points for conservation awareness and action. Formalized within the framework of conservation marketing, flagship species are focused around particular goals and audiences. Think of the WWF’s Giant Panda, Polar Bears and a thousand different arctic or climate change campaigns, or even the American Bald Eagle, whose decline galvanized the country into action. These animals are iconic. They connect people to species and ecosystems in crisis. They are Flagship Species.

The Giant Deep-sea Isopod is not a flagship species. The Giant Deep-sea Isopod addresses a much more fundamental issue: despite being the largest, most diverse ecosystem on the planet, most people have no direct connection, no frame of reference, for the deep sea.

The plague-busting, prairie-dog-vaccinating, ferret-saving drone

The US Fish and Wildlife Service is adapting new technology to the business of saving and endangered species: they’re sending in the drones.

Black-footed ferrets are a small, solitary, extremely territorial weasel-like animal that lives in the American west. Once abundant in central North America, today, their wild population stands at around 500. Black-footed ferrets were decimated by sylvatic plague (a close relative of the bubonic plague), as well as habitat loss and an early eradication campaign.

Time to release the Kraken ! Addressing controversial questions in marine conservation

Conservation, Uncategorized

A few years ago, we organized a group of marine conservation scientists to meet to discuss, and list, the most urgent issues that need to be studied. The resulting paper came up with 71 questions which urgently needed to be addressed, because a lack of an answer was severely impeding marine conservation. However, during this exercise we also came up with a list of other questions – these were issues that were controversial, that everyone knew were important, but were unwilling to raise as being an issue. These were the Voldemorts of marine conservation questions (they that shall not be named), the elephant (or elephant seal) in the room questions …. or as we more aquatically termed them: “the kraken in the aquarium” questions.

Conservation Wanted – dead or alive?

When I was an undergraduate studying conservation in the dim and distant past, we were told that the way endangered species would be saved would be to give them a financial value, and “wise use” of these species would allow them to survive. Well, that worked well, didn’t it…? The poster species of the “wise use” movement (such as elephants) are much closer to extinction today than they were decades ago.

The 2016 presidential candidates address ocean issues (sort of).

Finally, after almost a year of silence, we have concrete responses from the leading presidential candidate about ocean health and, in particular, the state of America’s fisheries. Well, sort of.

ScienceDebate.org, a non-partisan science advocacy group, asked the four leading candidates a slew of 20 science-related questions, including the following about ocean health:

“There is growing concern over the decline of fisheries and the overall health of the ocean: scientists estimate that 90% of stocks are fished at or beyond sustainable limits, habitats like coral reefs are threatened by ocean acidification, and large areas of ocean and coastlines are polluted. What efforts would your administration make to improve the health of our ocean and coastlines and increase the long-term sustainability of ocean fisheries?”

sciencedebate.org

Gary Johnson and Donald Trump declined to answer (Johnson declined to answer any question, Trump’s submitted boilerplate copy that makes no mention of the oceans or any ocean issue).

Jill Stein’s succinct response acknowledged the problems that overfishing, climate change, and ocean plastics pose to the oceans, but provides no specific policy recommendations.

On September 24th, the 17th Conference of the Parties (COP17) of the Convention on International Trade in Endangered Species (CITES) begins. I’ve made a Storify guide to government agencies, scientists, activists, and environmental non-profits who will be tweeting updates from the event. If you want to follow along with these important conservation debates and votes on twitter, follow #COP17 and follow the accounts I’ve highlighted in this Storify.

Fun Science FRIEDay – Shark Daycare

A great white shark nursery in the North Atlantic that was discovered in 1985 south of Cape Cod in the waters off Montauk, New York has received renewed attention due to the increased activity of white sharks off cape cod in recent years. The nursery was first documented in 1985 by Casey and Pratt who deduced the presence of a nursery based on the number of juvenile sightings and landings in the area. This work was followed up recently by OCEARCH (an organization dedicated to generating scientific data related to tracking/telemetry and biological studies of keystone marine species such as great white sharks), which tagged and tracked nine infant great whites to the nursery, located a few miles off Montauk.
