Methane Is Discovered Seeping From Seafloor Off East Coast, Scientists Say
2014-08-24 20:32:00| Climate Ark Climate Change & Global Warming Newsfeed
New York Times: Scientists have discovered methane gas bubbling from the seafloor in an unexpected place: off the East Coast of the United States where the continental shelf meets the deeper Atlantic Ocean. The methane is emanating from at least 570 locations, called seeps, from near Cape Hatteras, N.C., to the Georges Bank southeast of Nantucket, Mass. While the seepage is widespread, the researchers estimated that the amount of gas was tiny compared with the amount released from all sources each year. In a paper...

Extent Marine Litter Documented in Major Seafloor Survey
2014-05-01 18:31:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: A major survey of the ocean floor has found trash piling up throughout the Atlantic and Arctic oceans and Mediterranean Sea, reaching depths of nearly 3 miles below the surface, according to scientists from 15 European research organizations. Litter was located at each of the 600 sites surveyed, with plastic accounting for 41 percent and derelict fishing gear 34 percent. Glass, metal, wood, cardboard, clothing, pottery, and unidentified materials were also found. Garbage accumulated at sites as far...

Seafloor Marine Life Face Major Threat from Climate
2014-01-19 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate News Network: Creatures which live deep beneath the ocean surface are likely to be badly hit by climate change over the next century, a new study says. The study, by an international research team from the UK, Canada, Australia and France, is the first to quantify future losses in deep-sea marine life, using advanced climate models. Life that thrives on the seafloor several miles below the surface of the ocean is likely to be severely affected by the changing climate. The researchers say their results...

Arctic Seafloor Releasing 17 Teragrams Methane Every Year, Study Finds
2013-11-26 10:32:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: The Arctic seafloor might have a larger methane time-bomb than previously assumed. A new study has found that the East Siberian Arctic Shelf is releasing 17 teragrams of methane each year, about twice as much as previous estimates. One teragram is about 1 million tons. What's worse is that climate change might be accelerating its release. The study was conducted by researchers at the University of Alaska, Fairbanks and colleagues. Methane is the second-most prevalent greenhouse gas in the...
