The ingredient was found nearly 200 miles from the wellhead two months after BP stopped applying dispersants. Tests indicate the amount found wasn’t toxic, but ‘we don’t really know what effect it had on the environment,’ the lead researcher says.

A key ingredient of the chemical dispersants released last summer at BP’s spewing wellhead persisted in the Gulf of Mexico’s deep waters for two months and was carried by currents nearly 200 miles, according to a study released Wednesday.
The research, conducted by scientists from California universities and the Woods Hole Oceanographic Institution in Massachusetts, sheds light on the fate of the 771,000 gallons of dispersants – which had never before been released at such depths – but does not address their effect on deep-sea life, or whether they worked as intended.
BP applied about 2 million gallons of dispersants to break down the oil during the four months it gushed into the gulf and to keep it from reaching sensitive shore environments. More than half that amount was sprayed on the water’s surface, but 771,000 gallons were pumped into the clouds of oil and gas that billowed from the seabed, nearly a mile below.

Sharp rise reported in Scots fish lice chemical (BBC)
/in Ocean Newswire/by Ocean DoctorThe level of chemicals used by fish farmers to treat sea lice infestations has risen dramatically, a BBC Scotland investigation has learned.
Scottish government figures showed that over the past five years, the industry used a broader range of chemicals and more of them.
Campaigners claim the figures are evidence the natural parasite is becoming resistant to the treatments.
Fish lice have been blamed for damaging salmon and sea trout stocks. Read more

Less Than Half of Students Proficient in Science
/in Ocean Newswire/by Ocean DoctorBy CHRISTINE ARMARIO
Associated Press
The nation’s students are still struggling in science, with less than half considered proficient and just a tiny fraction showing the advanced skills that could lead to careers in science and technology, according to results from an exam released Tuesday.
Only 1 percent of fourth-grade and 12th-grade students, and 2 percent of eighth-graders scored in the highest group on the 2009 National Assessment of Educational Progress, a federal test known as the Nation’s Report Card.
“Our ability to create the next generation of U.S. leaders in science and technology is seriously in danger,” said Alan Friedman, former director of the New York Hall of Science, and a member of the board that oversees the test.

Saving Our Seas with an eBay Guitar: The Arts and Ocean Literacy
/in Podcast/by Ocean DoctorJanuary 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.

BP’s Disaster Down Under
/in Ocean Newswire/by NewswireCurrently, the massive area’s sprinkling of residents enjoy the company of endangered marine life, including snubfin dolphins, sawfish, turtles, dugongs and lots of fish. They are also fortunate to host the world’s largest population of humpback whales. One of the endangered species endemic to this region is flatback turtles, with approximately 1,000 of them nesting annually at an island off the coast.
However, the unspoiled, delicate environment could soon be over-run with visitors from unsavory entities such as Woodside Petroleum, Chevron, Shell, BP and BHP Billiton. If one remembers our Gulf of Mexico disaster last summer, it’s obvious that these companies aren’t exactly ocean-friendly neighbors.

President Obama Signs Shark Conservation Act
/in Ocean Newswire/by Ocean DoctorPresident Obama has signed into force the Shark Conservation Act, which prohibits almost all shark finning by U.S. vessels and in U.S. waters. The president signed the act on January 4, two weeks after the House and Senate passed the bill.
The act requires any U.S. vessel to land sharks with their fins attached and prevents non-fishing vessels from transporting fins without their carcasses. The new law also allows the United States to block seafood imports from countries that permit shark finning.
