November 22, 2009 - A team studying the effects of acidification on ocean reefs, caused by dissolved CO2, found that it leaves fish unable to "smell danger". Young clownfish that were reared in the acidified water became attracted to rather than repelled by the chemical signals released by predatory fish. Here's the story from the BCC.Sea Life

November 18, 2009 - Scientist Richard Greenberg has found evidence that the ocean encircling Jupiter's moon Europa is likely to have the conditions necessary to support larger forms of underwater life. Speaking last month at a meeting of the American Astronomical Society's Division for Planetary Sciences he said, "There's nothing saying there is life there now... But we do know there are the physical conditions to support it." It is believed that the sea floor of Europa has hydrothermal vents similar to those on the deep sea floors of Earth's own oceans. On Earth the vents provide warmth and nutrients to support a wide range of life. Oxygen is necessary for life too and more oxygen can support more and larger life forms. Greenberg's research found that Europa's ocean may have more than a hundred times more oxygen than was thought previously. He believes that at least three million tons of fishlike creatures could theoretically live and breathe on the planet. Here's the full story from NationalGeographic.com

Sea Turtle Rescued from Wellfleet Marsh
October 15, 2009 - A 175-pound adult female loggerhead was discovered in the Drummer Cove Pond salt marsh in Wellfleet by a Rhode Island man on Sunday evening. The man contacted officials at the Massachusetts Audubon Society sanctuary, who decided to wait and see whether the turtle would return to the water on her own. The turtle stayed on the beach. When the turtle was examined on Monday morning she was found to be hypothermic. She is now recovering in a water tank at the New England Aquarium. If all goes well she will be taken to the Mid Atlantic and released there in the next week. Here's the full story at Boston.com.

October 7, 2009 - Here's what technology can do. It can put put miniature digital cameras, each about the size of a large lipstick and weighing about 3 ounces (82 grams), onto the backs of four black-browed albatrosses breeding at colonies on Bird Island, South Georgia, in the Southern Ocean. After reviewing some 28,725 images researchers discovered that albatrosses enjoy feeding on killer whale leftovers. Here's the full story from Jeanna Bryner at LiveScience.com. The National Institute of Polar Research in Japan fitted the camera to the albatross who delivered the image above.
