摘　　要：Owing to global warming,frequent ice shelf disintegration and rapid acceleration of inland ice flow have occurred in recent decades,which impacts the Antarctic mass balance and the global sea level[1].These events are closely linked to atmospheric and oceanic processes.The prolonged melt season and larger extent of melt ponds on the ice shelf surface[2],as well as enhanced basal melting caused by warmer sea water[3],will induce crevasses thatOwing to global warming, frequent ice shelf disintegration and rapid acceleration of inland ice flow have occurred in recent decades, which impacts the Antarctic mass balance and the global sea level [1]. These events are closely linked to atmospheric and oceanic processes. The prolonged melt season and larger extent of melt ponds on the ice shelf surface [2], as well as enhanced basal melting caused by warmer sea water [3], will induce crevasses that expand and enhance fracturing of Antarctic ice shelves. The calved icebergs comprise a massive fresh water reserve, and ice- berg evolution can affect ecological and oceanic environ- ments, such as phytoplankton blooms, the fresh water balance in the Southern Ocean and the growth and decay of local sea ice, especially the alongshore fast ice [4]. Antarctic scientific research expeditions will also be affected.
