27 October 2016, Aust Antarctic Division, Impact of East Antarctic glacial melt on sea-level rise. The Australian Antarctic Program will study two glaciers, the Totten and Sørsdal, in East Antarctica this summer to better understand the impact ice melt is having on global sea-level rise. The Totten Glacier, near Australia’s Casey research station, is the largest glacier in East Antarctica, and is showing signs that it is sensitive to warm ocean waters that can increase melt at the base of the ice shelf. Australian Antarctic Division Glaciologist, Dr Ben Galton-Fenzi, said researchers want to better understand how much this glacial melt is driving sea-level rise. “Since the 1900s the global sea-level has risen by around 20 centimetres and by the end of the century it’s projected to rise by up to one metre or more, but this is subject to high uncertainty,” Dr Galton Fenzi said. “These estimates depend critically on understanding Antarctic glaciers, both how much and how fast they melt in a warming climate. This summer researchers will look at how warmer ocean water is melting glaciers and ice shelves from below. “We will land helicopters on the Totten to deploy six GPS units to measure glacial flow speeds and surface elevation changes.
