Outline of Final Research Achievements

Using GRACE gravity data, Envisat altimeter data, RACMO surface mass balance model and snow-stakes data by the Japanese Antarctic Research Expedition, we estimated the ice sheet mass balance at the Shirase Glacier basin in Enderby Land, Antarctica. The result shows that the recent ice-sheet mass increase is mainly due to the snow accumulation, particularly near the coastal areas. Next, we compared the GRACE and the snow-stakes data via RACMO model adjusted by the GRACE data for the period of 2008-2012, when excess mass accumulation was observed. The snow-stakes observation measures the successive height changes of the surface snow. The observed height changes only include the snow accumulation and sublimation without the component of the runoff effects. Therefore the difference between the snow-stakes and the GRACE data can reveal the mass changes caused by runoff, and the change of the runoff velocity. The comparison result shows no distinct change occurred during the period.
