Decadal Northern Hemisphere marine-terminating glacier positions, 2000-2020

The main goal of this dataset is to quantify the area change of all marine-terminating glaciers in the Northern Hemisphere. It was originally developed in 2020 to compute frontal ablation for all the glaciers (outside the Greenland Ice Sheet). It was then expanded to include all of Greenland in 2021. We documented every glacier in the hemisphere and provide unique identifiers for each glacier so that they can be used in conjunction with other datasets.
