Loggerhead sea turtle hatchling by Jacey Biery
There is nothing more satisfying than when wonderful surprises turn up in unexpected places — like a $5 bill left in your blue jeans, or loggerhead sea turtles in Mississippi. Wait, what?
Yep. After an absence of 20 some odd years, two loggerhead sea turtle nests on Mississippi’s coast have scientists scratching their heads over what Institute for Marine Mammal Studies executive director Dr. Moby Solangi is calling a “very important and significant phenomena.”
Experts are not sure why these turtles chose to nest on the Mississippi coast this year. Whether due to a loss of ideal habitat in other areas, or competition for prime nesting space, this year is an usual one for sea turtles in the Gulf. Continue reading »

Like a zombie, the dead zone in the Gulf of Mexico just won’t seem to really die. Estimates for the size of this year’s dead zone, an area of water so deprived of oxygen that it can’t support life, were just released by LUMCON (Louisiana University Marine Consortium) and the University of Michigan.
LUMCON estimates the size of the 2012 dead zone at 6,123 square miles, while the more conservative estimate projects an area of 1,197 square miles. While these estimates differ as much as the best way to kill a zombie does, what is really important is that there is a dead zone in the Gulf of Mexico. Continue reading »

Sea turtles need help. All sea turtles in U.S. waters are on the Endangered Species List as either threatened or endangered. They are often bycatch—unwanted animals caught in nets and other fishing gear. This is one of the most serious threats to the recovery and conservation of sea turtle populations.
But, an escape plan has been hatched. Turtle excluder devices, or TEDs, prevent turtles from becoming entangled and drowning in shrimp fishermen’s nets. TEDs are a set of bars fitted into the neck of a net with an escape hatch. When a sea turtle is caught in a net with a TED, it is stopped against the bars and escapes through the hatch. Shrimp and other critters fishermen want to catch pass through the bars and are collected at the end of the net. TEDs have been used successfully in U.S. shrimp fisheries since the late 1970s, but unfortunately not everyone uses TEDs. Continue reading »
