Antarctic Ice Dissolving From Underneath
Researchers
during the first comprehensive consideration of the thick platforms of
floating ice brought into prominence on Thursday that the moderate
degree of heat under ocean waters
are melting the Antarctic ice shelves from the bottom up. Scientists
have long known that basal melt, the melting of ice shelves from
underneath, was taking place at the same time regarded as resulting from a specified cause of the trend to icebergs breaking off the platforms.
On the
contrary the new study, that supposed to get published in Friday's issue
of the journal Science revealed that most of the lost mass came from
the bottom and not from the top.
Lead author Eric Rignot of Nasa's Jet Propulsion Laboratory and the
University of California, Irvine explained that their study showcases
melting from below by the ocean waters
is at a greater extent, at the same time this should change their
perspective on the evolution of the ice sheet in a moderately high
temperature atmosphere.
