Researchers provide detailed picture of ice loss following collapse of Antarctic ice shelves

Contact: Patrick Lynch, NASA’s Goddard Space Flight Center, Greenbelt, Md., 757-897-2047, patrick.lynch@nasa.gov 25 July 2011 An international team of researchers has 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 shelves. The work by researchers at the University […]

Rising oceans: Too late to turn the tide?

By Daniel Stolte, University Communications 14 July 2011 Melting ice sheets contributed much more to rising sea levels than thermal expansion of warming ocean waters during the Last Interglacial Period, a UA-led team of researchers has found. The results further suggest that ocean levels continue to rise long after warming of the atmosphere levels off. […]

Penguin, krill populations in freefall as Antarctic warms

By Jessica Marshall11 Apr 2011 Numbers of Chinstrap and Adélie penguins in the Antarctic Peninsula region have dropped by more than 50 percent in the last 30 years, driven mainly by dramatic declines in supplies of tiny, shrimp-like krill, their main prey, says a new study. Krill, meanwhile, have declined by 40 to 80 percent, […]

Graph of the Day: Polar Ice Mass Balance, 1992-2010

Caption by Mike Carlowicz, with background from Alan BuisMarch 26, 2011 According to a new NASA-funded satellite study, the Greenland and Antarctic ice sheets are losing mass at an accelerating pace and are overtaking ice loss from mountain glaciers and ice caps to become the dominant contributor to global sea level rise. The graph above […]

King crabs invade Antarctica

By Eric NiilerMarch 20, 2011 Sven Thatje has been predicting an invasion of deep-water crabs into shallow Antarctic waters for the past several years. But the biologist and his colleagues got their first look at the march of the seafloor predators while riding on an icebreaker across frozen Antarctic seas this winter. The ship towed […]

Image of the Day: Retreat of Sea Ice in McMurdo Sound, Antarctica, 2003-2011

Caption by Holli RiebeekMarch 10, 2011 Early in February 1902, Captain Robert Falcon Scott sailed into McMurdo Sound and docked his ship, the Discovery, in a small, sheltered bay at the tip of a rocky peninsula on Ross Island. Eager to begin a year exploring one of Earth’s last untouched places, Scott and his men […]

Melting ice sheets are largest contributor to sea level rise – Melt rates in Greenland and Antarctica are accelerating

ScienceDaily (Mar. 8, 2011) — The Greenland and Antarctic ice sheets are losing mass at an accelerating pace, according to a new NASA-funded satellite study. The findings of the study — the longest to date of changes in polar ice sheet mass — suggest these ice sheets are overtaking ice loss from Earth’s mountain glaciers […]

‘Crazy green’ algae pools seen in Antarctic Sea

By Christine Dell’Amore, National Geographic NewsPublished February 28, 2011 “Crazy green” pools teeming with life have been found among remote Antarctic sea ice, scientists say—and they may be a global warming boon. Observed in the little-studied Amundsen Sea (see map), the brilliant blooms owe their colors to chlorophyll, a pigment in various types of phytoplankton, […]

Video: Greenland’s glaciers double in speed

February 21, 2011 (PhysOrg) – The contribution of Greenland to global sea level change and the mapping of previously unknown basins and mountains beneath the Antarctic Ice Sheet are highlighted in a new film released by Cambridge University this morning. The work of glaciologist Professor Julian Dowdeswell, Director of Cambridge University’s Scott Polar Research Institute, […]

Emergency airlift from Antarctica bases as Ross Ice Shelf breaks up

By MICHAEL FIELD26 February 2011 (Stuff) – An Antarctic ice shelf used as a runway is breaking away, forcing an emergency airlift to close summer operations on the continent. The situation is being complicated by the Christchurch quake which is limiting operations at Christchurch Airport. Staff at New Zealand’s Scott Base and the US’s McMurdo […]
