On Science and Technology: Antarctic ice melt from below, a new study reports that 55% of the ice loss is due to melting at the base of these vast ice sheets.
And are responsible for most of the continent’s ice shelf mass loss, a new study by NASA and university researchers has found.
Antarctic Ice Melt The study uses reconstructions of ice accumulation, satellite and aircraft readings of ice thickness, and changes in elevation and ice velocity to determine how fast ice shelves melt and compare the mass lost with the amount released by the calving, or splitting, of icebergs.
It shows that it could lead to more accurate predictions of sea level rise. In total, Antarctic ice shelves lost 1,325 trillion kilograms of ice per year in 2003 to 2008 through basal melt, while iceberg formation accounted for 1,089 trillion kilograms of mass loss each year.
