Decadal changes from a multi-temporal glacier inventory of Svalbard
We present a multi-temporal digital inventory of Svalbard glaciers with the most recent from the late 2000s containing 33 775 km 2 of glaciers covering 57% of the total land area of the archipelago. At present, 68% of the glacierized area of Svalbard drains through tidewater glaciers that have a tot...
