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.

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，主要表现为围绕南极大陆的南极冰架解体。冰架上的崩解过程可能导致世界各地海平面大幅上升，对大陆海岸和低洼岛屿造成破坏性影响。该项目中研究的远程声学观测方法是一种新的方法，以建立一个有效的和具有成本效益的系统来监测南极冰架的断裂和崩解的问题。
