Abstract Over the past two decades, Antarctic ice shelves have retreated, thinned and suffered catastrophic collapse. In this study we extended the 25-year long record of ice shelf thickness change in Antarctica, from 2010 to 2017. In the Amundsen Sea Sector where widespread ice shelf thinning dominates the signal, a 51 % slowdown in the rate of ice loss over the last 7-years can be attributed to a coincident decrease in ocean temperatures in the region since 2010. Overall, ice shelves in Antarctica have thickened by an average of 1.3 meters between 2010 and 2017 as ice losses from West Antarctica are compensated by ice gains in East Antarctica and the Antarctic Peninsula, reversing the negative trend of the previous two decades. The detailed spatial pattern of ice shelf thickness change across Antarctica, demonstrates the need for future investment in high spatial resolution observations and techniques.

延长南极冰架厚度变化记录，从 1992 年到 2017 年

摘要 过去二十年来，南极冰架退缩、变薄并遭受灾难性的崩塌。在这项研究中，我们将南极洲冰架厚度变化长达 25 年的记录从 2010 年延长到 2017 年。在阿蒙森海区，普遍冰架变薄占主导地位，冰架损失速度在过去的 2010 年下降了 51%。过去 7 年可归因于自 2010 年以来该地区海洋温度同时下降。总体而言，南极洲的冰架在 2010 年至 2017 年间平均增厚了 1.3 米，因为南极洲西部的冰损失由东南极洲和南极半岛，扭转了前二十年来的不利趋势。南极洲冰架厚度变化的详细空间格局，
