Abstract

The loss of mass from the Greenland ice sheet causes an increasing influx of freshwater to the Greenlandic fjords and the oceans. Freshwater fluxes from marine-terminating glaciers are important to understand fjord circulation and ecosystem dynamics. Here, we present a data set constructed by reformulating existing products into a shared temporal and spatial framework. We combine three publicly available data sets of solid-ice discharge (iceberg), liquid-surface runoff (runoff) and basal melt to present a cohesive overview of the flow of freshwater from marine-terminating glaciers to the Greenlandic fjords. We also calculate glacier drainage basins and compare our findings to previous studies showing that drainage-basin sizes may vary considerably depending on how they were reconstructed. The data set will be a valuable asset to oceanographic, glaciological and marine biological research activities.
2010-2020年冰川-盆地尺度上格陵兰冰盖海洋终止冰川的月度淡水通量数据集
格陵兰冰盖的质量损失导致越来越多的淡水涌入格陵兰峡湾和海洋。来自海洋终端冰川的淡水通量对于理解峡湾环流和生态系统动力学非常重要。在这里,我们展示了一个数据集,该数据集是通过将现有产品重新制定为共享的时间和空间框架而构建的。我们结合了三个公开可用的数据集,即固体冰流量(冰山)、液体表面径流(径流)和基底融化,对从海洋终止冰川到格陵兰峡湾的淡水流进行了综合概述。我们还计算了冰川流域,并将我们的发现与之前的研究进行了比较,这些研究表明,流域的大小可能会因重建方式的不同而有很大差异。该数据集将成为海洋学、冰川学和海洋生物研究活动的宝贵资产。
