Oceans Melting Greenland campaign (OMG)

UCI, NASA reveal new details of Greenland ice loss Data are dramatically increasing knowledge of how the ocean is melting the ice sheet From the UNIVERSITY OF CALIFORNIA – IRVINE Irvine, Calif., February 9, 2017 – Less than a year after the first research flight kicked off NASA’s Oceans Melting Greenland campaign, data from the…

Studies worry: Is Greenland on thin ice?

From the UNIVERSITY OF VERMONT Greenland on thin ice? Two studies in Nature open deep history of Greenland’s ice sheet — and raise new questions about its stability The ice sheet covering Greenland is four times bigger than California — and holds enough water to raise global sea-level more than twenty feet if most of it…

Oh, darn. Study: Most meltwater in Greenland fjords likely comes from icebergs, not glaciers

From the AMERICAN GEOPHYSICAL UNION Most meltwater in Greenland fjords likely comes from icebergs, not glaciers WASHINGTON, DC — Icebergs contribute more meltwater to Greenland’s fjords than previously thought, losing up to half of their volume as they move through the narrow inlets, according to new research. Greenland, the world’s largest island, is almost entirely…

Study: ‘accelerated melting of the lower Greenland ice sheet’ due to bacteria darkening the surface albedo

From RESEARCH ORGANIZATION OF INFORMATION AND SYSTEMS and the “dirty snow” department. Factors promoting growth of cryoconite granule formation and glacial/ice sheet melting Cryoconite granules (see Figure 1) are dark, millimeter-sized aggregations of bacteria and algae, mineral particles and organic matter that form on the surface of glaciers. They are also known to be a significant…
