我们结合了五次卫星高度计任务所获得的测量结果，以获得自1992年以来西南极阿蒙森海湾冰盖海拔变化的不间断记录。使用这些数据，我们通过跟踪冰川流线上的海拔变化，检查了由于冰动力不平衡而引起的表面下降的开始，以及它向内陆传播的速度。地表下降的蔓延速度最慢(
We combine measurements acquired by five satellite altimeter missions to obtain an uninterrupted record of ice sheet elevation change over the Amundsen Sea Embayment, West Antarctica, since 1992. Using these data, we examine the onset of surface lowering arising through ice-dynamical imbalance, and the pace at which it has propagated inland, by tracking elevation changes along glacier flow lines. Surface lowering has spread slowest (
