Vertical heat transport in Greenland fjords induced by iceberg capsize

格陵兰岛的海洋终止冰川通过崩解将大量冰山排入沿海峡湾。冰山和海冰的密集矩阵在冬季形成，但在春季和夏季，海冰融化，使冰山扩散和旋转（或“倾覆”）。该项目将研究冰山倾覆在多大程度上促进格陵兰峡湾的热迁移。这项工作可以结合融化速率参数化和峡湾环流模型，以获得从格陵兰冰盖到极地海洋的淡水通量的精确估计。

Marine-terminating glaciers in Greenland discharge large volumes of icebergs into coastal fjords by calving. A dense matrix of icebergs and sea ice forms during winter, but in spring and summer the sea ice melts and allows the icebergs to spread out and rotate (or "capsize"). This project will study the extent to which iceberg capsizing contributes to thermal transport in Greenland fjords. This workcould be combined with melt rate parametrisations and fjord circulation models to obtain refined estimates of freshwater flux from the Greenland Ice Sheet into the polar oceans.
