Where Sea Turtles and Fishing Boats Meet

A study published in the April 2012 issue of Ecological Applications uses satellite telemetry data to identify danger zones where sea turtles and fishing trawlers intersect at sea — with deadly consequences. The insights provided by the study will assist regulatory agencies determine limits to fishing, such as seasonal closures, to protect sea turtles, all seven species of which are considered endangered.




The researchers followed 135 females, some from the eastern Pacific and some from the western Pacific, over 15 years as they crisscrossed the ocean hunting for jellyfish. The study found that the migration patterns for the two Pacific populations were different. Western Pacific leatherbacks leave Indonesian nesting sites to feed in the South China Sea, Indonesian seas and southeastern Australia and along the U.S. West Coast, making them vulnerable to fishing nets in many different areas.

The eastern Pacific leatherbacks traveled from nesting sites in Mexico and Costa Rica to the southeastern Pacific, with many getting snagged in fishing gear along the coast of South America. Because the eastern population is more concentrated in range, its risk of extinction is greater, Bailey says.

The new findings could help decision makers plan short-term fishery closures. Bailey credits a recent decision to close a swordfish and thresher shark fishery in California from mid-August to mid-November each year with dramatically reducing leatherback bycatches. (In 2010 no turtles were caught.)

Saving Our Seas with an eBay Guitar: The Arts and Ocean Literacy

The Ocean Doctor on WebTalkRadio.net

January 24, 2011: Like it or not, our kids are going to inherit an oiled Gulf and a troubled ocean, and their generation will ultimately have to deal with problems we’ve created. But how do we ensure they’re up to the challenge? If you listen to multimedia artist and conservationist Mark Holmes, reaching our kids through the arts is a powerful approach and that’s exactly what he’s doing with the newly-formed Institute for Ocean Literacy. Mark formerly worked at National Geographic where he launched the NationalGeographic.com web site and designed and art directed National Geographic Magazine. His music, graphic novels, and passion are helping to inspire our next generation. Also: Our in-depth coverage of the National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling continues as the Ocean Doctor guides you through the highlights of its final report.

The Ocean Doctor on WebTalkRadio.net

December 6, 2010: Join The Ocean Doctor, along with Ocean Foundation Research Fellow, Fernando Bretos, on a field trip to Havana to visit with Cuba’s next-generation of marine scientists at the University of Havana’s Center for Marine Research (Centro de Investigaciones Marinas). We visit with the Center’s new director, Dr. Jorge A. Angulo Vald’s. We also visit with Dr. Julia Azanza Ricardo who directs the Center’s unique sea turtle research and conservation program in the wilds of Guanahacabibes Biosphere Reserve on Cuba’s western tip. For these two and their colleagues, their passion for the sea runs deep, thanks in large part to two influential people in their lives: Jacques Cousteau and Fidel Castro.

Cuba and the U.S. Find Friendship and Hope in the Gulf of Mexico

The Ocean Doctor on WebTalkRadio.net

October 18, 2010: After 50 years without formal diplomatic relations and no end to the last vestiges of the Cold War in sight, marine scientists and conservationists have taken matters into their own hands to form the Trinational Initiative for Marine Science and Conservation in the Gulf of Mexico and Western Caribbean, a unique partnership of Cuba, Mexico and the United States that is working past political barriers to make a difference for the waters we share and forging new friendships along the way. The Trinational Initiative recently held its fourth meeting in Sarasota, Florida and after nearly a decade of the Administration denying visas, more than 20 Cubans received their visas and participated in the meeting. The Ocean Doctor leads the meeting and shares its successes.

Want to Help the Gulf of Mexico? Kill Your Lawn.

Want to Help the Gulf of Mexico? Kill Your Lawn.

The Lawn has Become as much of an American Icon as Baseball and Apple Pie. But at What Cost? (Photo credit: From the cover of “The American Lawn” by Georges Tevssot)

Since 1948, radio station KBMW has been serving as the “Voice of the Southern Red River Valley,” a tri-state area including North Dakota, South Dakota and Minnesota, boasting some of the “richest farmland in the United States.” So why did they want to interview a city boy who lives for salt water? To update their listeners on the BP oil spill disaster in the Gulf of Mexico, and most importantly, tell their listeners how they could help. Like so many of us, they feel a deep connection to the Gulf, even from more than 1,200 from water’s edge, and the daily images of oil erupting from the BP well has led to palpable frustration. It’s hard to watch and not be able to help. Truth is, KBMW’s listeners are more connected than they may realize, and they can materially help the Gulf of Mexico — and their own neighborhoods, by just getting outside and doing some gardening.
