'Dirty Blizzard' sent 2010 Gulf oil spill pollution to seafloor
2016-05-31 02:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Scientists working in the Gulf of Mexico have found that contaminants from the massive 2010 Deepwater Horizon oil spill lingered in the subsurface water for months after oil on the surface had been swept up or dispersed. In a new study, they also detailed how remnants of the oil, black carbon from burning oil slicks and contaminants from drilling mud combined with microscopic algae and other marine debris to descend in a "dirty blizzard" to the seafloor. The work, published May 30 in the Proceedings...

Antarctic Seafloor Life Is Locking Away a Lot of Carbon, Study Says
2015-09-22 19:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: The loss of sea ice over Antarctic waters has caused certain forms of life to flourish on the seafloor, and those underwater communities are acting as important and unexpected carbon sinks, according to research published in the journal Current Biology. Based on studies of West Antarctic bryozoans aquatic invertebrates sometimes referred to as "moss animals" researchers have found that those and other seafloor organisms could play important roles in accumulating and burying carbon, removing it...
Microbes in the seafloor: Little nutrients, lots of oxygen
2015-03-16 11:00:00| LifeSciencesWorld
[NEWS] About one quarter of the global seafloor is extremely nutrient poor. Contrary to previous assumptions, it contains oxygen not just in the thin surface layer, but also throughout its entire thickness. The underlying basement rocks contain oxygen as well. An international research team made these new discoveries through analysis of drill cores from the South Pacific Gyre. In the latest issue of Nature Geoscience the scientists also point out the potential effects on th…

More seafloor methane released into Pacific Ocean
2014-12-12 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Science Times: Water at intermediate depths is observed to be warming up as seafloor methane released into the Pacific Ocean is growing at an alarming rate, a recent study found. The said warming is happening at such a point where deposits of carbon will start to melt and free methane into the water. These deposits of methane gas, frozen in layers underneath the seafloor, are beginning to melt, thus, releasing methane into sediments and the surrounding waters, according to the University of Washington research....
