Acoustic observation of Antarctic ice rifting and calving events using remote hydroacoustic listening stations

南极冰架的崩解活动是全球气候变化的主要指标之一。大气中二氧化碳含量增加引起的全球变暖将影响南极冰盖，主要表现为南极大陆周围的冰架解体。冰架上的崩解过程可能会导致世界各地海平面的大幅上升，对大陆海岸和低洼岛屿造成毁灭性的影响。本项目所研究的遥声观测方法是建立一个有效和成本效益高的系统来监测南极冰架裂解和崩解这一问题的新途径。

The calving activity of the Antarctic ice shelves is one of the major indicators of global climate change. Global warming induced by an increase in atmospheric CO2 will affect the Antarctic Ice Sheet, primarily in form of disintegration of the Antarctic ice shelves surrounding the continent. The processes of calving on the ice shelves may lead to a substantial increase of sea level around the world, with devastating effects on the continental coasts and low-lying islands. The method of remote acoustic observations investigated in this project is a new approach to the problem of creating an efficient and cost effective system to monitor rifting and calving of the Antarctic ice shelves.
