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.

绿地中的海洋末端冰川通过产犊将大量冰山排入沿海峡湾。冬季，冰山和海冰的密集矩阵，但在春季和夏季，海冰融化，使冰山可以散开并旋转（或“倾覆”）。该项目将研究冰山倾斜促进格陵兰峡湾热运输的程度。这项工作应该与熔体​​速率参数和峡湾循环模型相结合，以获得从格陵兰冰盖到极地海洋的淡水通量的精制估计。
