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.

格陵兰岛的海洋冰川通过崩解将大量冰山排入沿海峡湾。冰山和海冰的密集基质在冬季形成，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对格陵兰峡湾热运输的影响程度。这项工作可以与融化速率参数化和峡湾环流模型相结合，以获得从格陵兰冰盖进入极地海洋的淡水通量的精确估计。
