Thus, its levels and seemingly constant calving have become ecological barometers that environmentalists have come to use to show just how fast our planet is heating up. http://phys.org/news238749315.html Space & Earth Tue, 25 Oct 2011 08:15:29 EST news238749315 Two ice shelves that existed before Canada was settled by Europeans diminished significantly this summer, one nearly disappearing altogether, Canadian scientists say in new research. http://phys.org/news236607088.html Space & Earth Fri, 30 Sep 2011 13:11:37 EST news236607088 A NASA scientist and her colleagues were able to observe for the first time the power of an earthquake and tsunami to break off large icebergs a hemisphere away. http://phys.org/news232026986.html Space & Earth Mon, 08 Aug 2011 13:50:11 EST news232026986 Stronger ocean currents beneath West Antarctica's Pine Island Glacier Ice Shelf are eroding the ice from below, speeding the melting of the glacier as a whole, according to a new study in Nature Geoscience. A growing cavity beneath the ice shelf has allowed more warm water to melt the ice, the researchers say—a process that feeds back into the ongoing rise in global sea levels. The glacier is currently sliding into the sea at a clip of four kilometers (2.5 miles) a year, while its ice shelf is melting at about 80 cubic kilometers a year - 50 percent faster than it was in the early 1990s - the paper estimates. http://phys.org/news228324328.html Space & Earth Sun, 26 Jun 2011 16:25:45 EST news228324328 (PhysOrg.com) -- Northern Illinois University and DOER Marine today unveiled a new 28-foot long, cigar-shaped robotic submarine to be used in exploration beneath the Ross Ice Shelf in Antarctica. http://phys.org/news213622530.html Space & Earth Fri, 07 Jan 2011 11:37:11 EST news213622530 Scientists have previously shown that West Antarctica is losing ice, but how that ice is lost remained unclear. Now, using data from Earth observing satellites and airborne science missions, scientists are closing in on ice loss culprits above and below the ice. http://phys.org/news211706584.html Space & Earth Thu, 16 Dec 2010 07:50:01 EST news211706584 (PhysOrg.com) -- Oceanographers are using data collected by elephant seals to improve their map of the seafloor on Antarctica's continental shelf.
