U.S. Vulnerabilities to Reduced Mollusk Harvests from Ocean Acidification Assessed
August 2, 2011 — Changes in ocean chemistry due to increased carbon dioxide (CO2) emissions are expected to damage shellfish populations around the world, but some nations will feel the impacts much sooner and more ... > full story -
The Last Great Wilderness: Human Impact on the Deep Sea
August 1, 2011 — Over 20 deep-sea experts participating in the Census of Marine Life project SYNDEEP conducted a semi-quantitative analysis of the most important anthropogenic impacts that affect deep-sea habitats at ... > full story -
Ancient Glacial Melting Shows That Small Amount of Subsurface Warming Can Trigger Rapid Collapse of Ice Shelves
August 1, 2011 — An analysis of prehistoric "Heinrich events" that happened many thousands of years ago, creating mass discharges of icebergs into the North Atlantic Ocean, make it clear that very small amounts of ... > full story -
Ancient Tides Quite Different from Today -- Some Dramatically Higher, Some Lower
August 1, 2011 — The ebb and flow of the ocean tides, generally thought to be one of the most predictable forces on Earth, are actually quite variable over long time periods, in ways that have not been adequately ... > full story -
Sea Level Rise Less from Greenland, More from Antarctica, Than Expected During Last Interglacial
July 28, 2011 — New research results are revealing surprising patterns of melting during the last interglacial period that suggest that Greenland's ice may be more stable -- and Antarctica's less stable -- than many ... > full story -
Researchers Map Long-Range Migrations and Habitats of Leatherback Sea Turtles in the Pacific Ocean
July 28, 2011 — Endangered leatherback sea turtles migrate and forage across vast areas of the Pacific Ocean and Indo-Pacific seas and require greater international collaboration for their protection, according to a ... > full story -
Mitochondria Share an Ancestor With SAR11, a Globally Significant Marine Microbe
July 25, 2011 — A recent study provides strong evidence that mitochondria share a common evolutionary ancestor with a lineage of marine bacteria known as SAR11, arguably the most abundant group of microorganisms on ... > full story -
Detailed Picture of Ice Loss Following the Collapse of Antarctic Ice Shelves
July 25, 2011 — Researchers have combined data from multiple sources to provide the clearest account yet of how much glacial ice surges into the sea following the collapse of Antarctic ice ... > full story -
Identical Virus, Host Populations Can Prevail for Centuries
July 21, 2011 — A scientist, analyzing ancient plankton DNA signatures in sediments of the Black Sea, has found for the first time that the same genetic populations of a virus and its algal host can persist and ... > full story -
Study Shows Small-Scale Fisheries' Impact on Marine Life
July 18, 2011 — Small-scale fisheries could pose a more serious threat to marine life than previously thought. Research shows that tens of thousands of turtles from across the Pacific are being captured through the ... > full story -
2011 Gulf of Mexico 'Dead Zone' Could Be Biggest Ever
July 18, 2011 — Researchers have examined the scope and size of this year's "dead zone" in the Gulf of Mexico and have measured it currently to be about 3,300 square miles, or roughly the size of Delaware and Rhode ... > full story -
Rising Oceans: Too Late to Turn the Tide?
July 18, 2011 — Melting ice sheets contributed much more to rising sea levels than thermal expansion of warming ocean waters during the Last Interglacial Period, scientists have found. The results further suggest ... > full story
