The Ice shelves of Antarctica are sensitive indicators of climate change. In the present proposal intensive investigations shall be carried out in the Amundsen Sea sector of Antarctica/Pine Island Bay. The investigations will combine remote sensing data with in situ observations, which will be gathered during the POLARSTERN cruise ANT-XXVI/3 to be scheduled for spring 2010. The new data shall be combined with observations carried out 2006 during the POLARSTERN cruise ANT-XXIII/4. The main scientific goals are the determination of the flow regime of the ice shelves in Pine Island Bay, of the ocean tides and of the ice shelf-ocean interactions. The thinning rates for the ice shelves will be determined. In addition, repeated GPS observation on bedrock will be used to investigate horizontal crustal movements in the context of plate kinematics and regional deformation. Vertical site displacements will be used to refine the present knowledge on glacial isostatic movements in the area of investigation.

南极洲的冰架是气候变化的敏感指标。在本提案中，应在南极洲/松岛湾的阿蒙森海区域进行密集调查。调查将把遥感数据与现场观测相结合，这些数据将在定于 2010 年春季进行的 POLARSTERN 巡航 ANT-XXVI/3 期间收集。新数据将与 2006 年 POLARSTERN 巡航 ANT-XXIII/4 期间进行的观测相结合。主要科学目标是确定松岛湾冰架的流态、海洋潮汐以及冰架与海洋的相互作用。冰架的减薄率将被确定。此外，对基岩的重复 GPS 观测将用于研究板块运动学和区域变形背景下的水平地壳运动。垂直场地位移将用于完善有关调查区域冰川均衡运动的现有知识。
