(Table 1) Mass loss of the Greenland Ice Sheet

Using satellite radar interferometry observations of Greenland, we detected widespread glacier acceleration below 66° north between 1996 and 2000, which rapidly expanded to 70° north in 2005. Accelerated ice discharge in the west and particularly in the east doubled the ice sheet mass deficit in the last decade from 90 to 220 cubic kilometers per year. As more glaciers accelerate farther north, the contribution of Greenland to sea-level rise will continue to increase.

本研究基于格陵兰岛卫星雷达干涉测量（satellite radar interferometry）观测数据，于1996年至2000年间在北纬66°以南区域检测到大范围冰川加速现象，该现象于2005年快速扩展至北纬70°一线。西部尤其是东部区域的冰体排放加速，使得近十年来格陵兰冰盖的质量亏损量从每年90立方千米增至220立方千米，增幅达到一倍。随着更多冰川向北纬更高纬度区域加速运动，格陵兰岛对全球海平面上升的贡献将持续提升。
