摘要
During the 21st century,the contribution of the Antarctic*Ice Sheet(AIS)to sea level rise has been increasing,affecting coastal regions and their large populations and economies(Moore et al.,2018).The ice loss from the AIS is driven primarily by increased melting of ice shelves by warm ocean waters and the subsequent acceleration,retreat and rapid thinning of the major outlet glaciers of the West Antarctic ice sheet(IPCC,2019).However,subglacial conditions(thermodynamics and hydrology)of AIS remain poorly understood,despite recent advances in satellite and ground-based observations,and this makes it difficult to project the amount of future ice loss.To better understand the most compelling scientific issues addressing subglacial conditions,and following several recent technical and operational advances,the National Natural Science Foundation of China(NSFC)launched a special program named the“Polar Basic Science Frontier”.
