在索尔兹冰川（Thwaites Glacier）的冰舌下方收集到的新地图以及更远海域的地图显示，存在着深 (> 1000 米) 且宽 (> 20,000 米) 的海沟，这些海沟引导着温暖的洋水流进入冰层之下，加速了融化，最终可能导致其崩塌。索尔兹冰川是西南极冰盖（WAIS）的一部分，面积相当于英国大小，[…]
Nature Communications, August 24 The floating Shirase Ice Tongue (a long and narrow projection of ice, connected an ice basin about the size of the United Kingdom) in Queen Maud Land, East Antarctica, has revealed surprisingly high basal melt rates of 7 to 16 m per year. These rates equal or surpass the melting rate underneath […]
Nature, August 20 The Greenland Ice Sheet lost a record-breaking 532 (± 58 Gt) of ice in 2019, up around 200 Gt in the early 2000s, when it first became clear that the ice sheet was losing mass. The two GRACE satellite missions also provided new insights on the sensitivity of the Greenland Ice Sheet to climate-related changes in […]
