Fun Science FRIEDay – Visualize the Seafloor

Posted on November 4, 2016November 7, 2016 By Kersey Sturdivant
Open Science, Science, Uncategorized

Happy FSF! As some of you may know (and for those who don’t), I study the bottom of the ocean, and I do so primarily using innovative technology to image the seafloor (e.g., Wormcam). The interesting work I’ve conducted has resulted in me having the opportunity to present my work to a larger lay audience, in the form of a TEDx presentation.

I am giving my TED talk with my good buddy and colleague Steve Sabo.  In our talk, “A Picture is Worth a Thousand Worms”, Steve & I will illustrate the significance of the ocean floor through advancements in underwater camera technology and data visualization, making complex science more accessible for everyone.

All this month we’ve be showing talks about how nature and evolution have inspired technology and design. I’d like to end with this talk by Jim Toomey, about how the nature simply inspires us as human beings. What stories have the oceans shared with you?

Weekly dose of TED – Kristina Gjerde: Making law on the high seas

Posted on February 18, 2011February 17, 2011 By Andrew Thaler
Uncategorized

The high seas are a black hole for ocean conservation. They lie beyond the jurisdiction of any single country and are largely open for unregulated exploitation. Even as we begin moving towards a pragmatic high seas conservation framework, we should keep in mind that many territorial waters are still left unprotected and open to illegal … Read More “Weekly dose of TED – Kristina Gjerde: Making law on the high seas” »

Weekly dose of TED – Peter Tyack: The intriguing sound of marine mammals

Posted on January 21, 2011January 19, 2011 By Andrew Thaler 1 Comment on Weekly dose of TED – Peter Tyack: The intriguing sound of marine mammals
Uncategorized

That marine mammals have a rich sonic life has been well understood for several decades. What we didn’t understand until recently is how much we’ve changed the ocean soundscape, and how much we will continue to change the soundscape. Many of our new alternative energy plans involve maritime structures – offshore wind farms, wave energy … Read More “Weekly dose of TED – Peter Tyack: The intriguing sound of marine mammals” »

That talk was a slightly longer version of the one above, with the addition that she had finished her Pacific voyage in Papua New Guinea. The question I pose to our readers is, what effect do these … Read More “Weekly dose of TED – Roz Savage: Why I’m rowing across the Pacific” »

Turtle excluder devices: analysis of resistance to a successful conservation policy

Posted on January 7, 2011December 31, 2011 By David Shiffman 9 Comments on Turtle excluder devices: analysis of resistance to a successful conservation policy
Conservation

Conservation efforts often have an associated tradeoff, and many proposed solutions are shot down because the costs are perceived to be too high. A conservation policy that benefited a charismatic endangered species with very little cost should be popular and enthusiastically adopted. However, even though turtle excluder devices greatly reduce sea turtle mortality and have very low costs, they were vigorously opposed by shrimpers. Though many factors contributed to this opposition to turtle excluder devices, analysis of quotes from newspaper articles reveals that one of the major issues was a failure of the conservation community to educate and communicate with shrimpers.

The problem

Most species of sea turtles are either threatened or endangered. Although they face many threats, a 1990 National Academy of Sciences study reached the conclusion that “drowning in shrimp trawls kills more sea turtles than all other human activities combined”. Trawling consists of dragging a large net behind a boat to catch shrimp. This fishing method has one of the highest bycatch rates of any used today, resulting in over 11 million metric tons of bycatch a year. Sea turtles breathe at the surface, and being trapped underwater in a net can be fatal if they aren’t freed in time. Adult loggerhead turtles can hold their breath for up to 45 minutes, but trawlers often wait up to four hours before hauling in their nets. This resulted in an estimated 48,000 sea turtles caught in trawl nets each year from 1973-1984 in U.S. waters, of which 11,000 died . Gulf of Mexico shrimping was particularly hard on loggerhead and kemp’s ridley sea turtles.
