Vertical Land Motion Due To Present-Day Ice Loss From Greenland's and Canada's Peripheral Glaciers
Greenland's bedrock responds to ongoing ice loss with an elastic vertical land motion (VLM) that is measured by Greenland's Global Navigation Satellite System (GNSS) Network (GNET). The measured VLM also contains other contributions, including the long-term viscoelastic response of the Ear...
