Study finds surprising Arctic methane emission sourceScienceDaily.com | 26 Apr 2012
The fragile and rapidly changing Arctic region is home to large reservoirs of methane, a potent greenhouse gas. As Earth's climate warms, the methane, frozen in reservoirs stored in Arctic tundra soils or marine sediments, is vulnerable to being released into the atmosphere, where it can add to global warming. Now a multi-institutional study has uncovered a surprising and potentially important new source of Arctic methane: the ocean itself.
Antarctic ice melting from warm waterNew Zealand Herald | 26 Apr 2012
Antarctica's massive ice shelves are shrinking because they are being eaten away from below by warm water, a new study finds. That suggests that future sea levels could rise faster than many scientists have been predicting.
Wind pushes plastics deeper into oceans, driving trash estimates upEurekAlert | 26 Apr 2012
Decades of research into how much plastic litters the ocean, conducted by skimming only the surface, may in some cases vastly underestimate the true amount of plastic debris, according to a University of Washington oceanographer publishing in Geophysical Research Letters.

Warm ocean currents cause majority of ice loss from AntarcticaEurekAlert | 26 Apr 2012
Reporting this week, Thursday 26 April, in the journal Nature, an international team of scientists led by British Antarctic Survey has established that warm ocean currents are the dominant cause of recent ice loss from Antarctica.
The Art of PteropodsWoods Hole Oceanographic Institution | 26 Apr 2012
Artist Cornelia Kubler Kavanagh is passionate about exploring the oceans great unknowns. Via her latest work, she has found a kindred spirit in Gareth Lawson, a biological oceanographer at Woods Hole Oceanographic Institution. Their unique collaboration, The Pteropod Project: charismatic microfauna, features a series of Kavanaghs aluminum and bronze sculptures of mostly microscopic sea snails that float freely in ocean currents.
POPULATIONS OF ARCTIC MARINE MAMMALS AND FISH INCREASING, BIRDS ON EDGE OF DECLINEcaff.is | 26 Apr 2012
Arctic marine mammals, fish, and birds are undergoing some surprising trends that, in some instances, can be partially linked to climate oscillations and changes in commercial harvest, according to a new report released by the Circumpolar Biodiversity Monitoring Program (CBMP), the cornerstone program of the Conservation of Arctic Flora and Fauna (CAFF), the Arctic Councils biodiversity working group.

On the eve of the Fisheries Council discussions in Luxembourg, Oceana has drawn attention to a new paper co-authored by fisheries scientist Dr. Rainer Froese and resource economist Martin Quaas, linking the council's poor decisions and disregard for scientific advice to the collapse of North Sea cod.
Sea change in salinity heralds shift in rainfallReuters | 26 Apr 2012
SINGAPORE (Reuters) - Scientists have detected a clear change in salinity of the world's oceans and have found that the cycle that drives rainfall and evaporation has intensified more than thought because of global warming.
Tiny sharks provide glowing clueBBC | 26 Apr 2012
Pygmy sharks, which glow to camouflage themselves, reveal some of the evolutionary origins of luminescent sharks, say scientists.
Shell says no to North Sea wind powerGuardian Unlimited | 26 Apr 2012
Shell will not be joining David Cameron's crusade to attract private sector investment into creating a North Sea wind revolution despite its commitment to turbines in the US. Simon Henry, the company's finance director, said Shell "can't make the numbers" add up to justify building offshore windfarms.
