El Niño und La Niña : GRACE misst Gegensätze im westantarktischen Schneefall

Two regions in West Antarctica have received increased attention over the last years due to their potential sensitivity to climate change: the Antarctic Peninsula, which currently experiences warming at rates greater than the global average (Vaughan, 2006), ongoing ice shelf disintegration and subse...

Description
Summary:Two regions in West Antarctica have received increased attention over the last years due to their potential sensitivity to climate change: the Antarctic Peninsula, which currently experiences warming at rates greater than the global average (Vaughan, 2006), ongoing ice shelf disintegration and subsequent glacier acceleration (Scambos et al., 2004); and the Amundsen Sea Sector (AS), where ice velocities, ice discharge and glacial imbalances are extreme compared to the rest of the continent (Rignot et al., 2008). The satellite gravimetry mission GRACE reveals interannual variations in ice mass related to varying snowfall, which is strongly influenced by the global climate phenomenon El Nino (Sasgen et al., 2010).
