| Scientists assess radioactivity in the ocean from Japan nuclear power facility Posted: 09 Dec 2011 02:19 PM PST With current news of additional radioactive leaks from the Fukushima nuclear power plants, the impact on the ocean of releases of radioactivity from the plants remains unclear. |
| Expanding dead zones are shrinking tropical blue marlin habitat Posted: 09 Dec 2011 12:02 PM PST Scientists sound an alarm that expanding ocean dead zones are shrinking the habitat for high value fish such as marlins, other billfish and tunas in the tropical northeast Atlantic Ocean. Without taking this phenomena into account, scientific fish stock assessments could provide false signals that stocks are healthy, when in fact they are not, thus allowing overfishing that further depletes these fish stocks. |
| 2010 spike in Greenland ice loss lifted bedrock, GPS reveals Posted: 09 Dec 2011 09:32 AM PST An unusually hot melting season in 2010 accelerated ice loss in southern Greenland by 100 billion tons – and large portions of the island's bedrock rose an additional quarter of an inch in response. That's the finding from a network of nearly 50 GPS stations planted along the Greenland coast to measure the bedrock's natural response to the ever-diminishing weight of ice above it. |
| The physics behind great white shark attacks on seals Posted: 09 Dec 2011 07:53 AM PST A new study examines the complex and dynamic interactions between white sharks and Cape fur seals in False Bay, South Africa; Offers new insights on physical and biological factors underlying predator-prey interactions in marine environment. |
| Landsat satellites track Yellowstone's underground heat Posted: 07 Dec 2011 02:57 PM PST Yellowstone National Park sits on top of a vast, ancient, and still active volcano. Heat pours off its underground magma chamber, and is the fuel for Yellowstone's famous features -- more than 10,000 hot springs, mud pots, terraces and geysers, including Old Faithful. |
