[U05-06] A new aspect of the polar science: integrated observations of the ice sheet mass loss for better prediction of the sea level rise
Keywords:Polar Science, Arctic, Antarctic, Sea level rise, Ice sheet
Greenland Ice Sheet amounts about 9 % of total ice mass on the glove, and its mass loss is becoming faster due to the rapid warming in the Arctic region. This causes acceleration of the global sea level rise. On the other hand, the Antarctic Ice Sheet, which as about an order larger mass, also indicating a significant mass loss in the western part. Once the East Antarctic Ice Sheet also started to melt quickly, which has much larger mass than the West Antarctic Ice Sheet, the sea level rise would become fatal. Thus, it is very important to understand the current variation of the ice sheets, which could cause more than 60 m of sea level rise as a total amount, and monitor its trend.
This proposal focuses on the sea level rise due to the ice sheet mass loss. We propose to carry out integrated observations at remote sites in the Antarctica and Greenland, by deploying new technical challenge with un-manned and remote controlled system. Then, by unifying in-situ observations, detailed analyses, satellite observations and numerical modelings, we plan to clarity variations of the ice sheet and ocean in the past and at present, then improve the forecast of future sea level rise, which might rapidly proceed even within this century.
