Closing Greenland's Mass Balance:Frontal Ablation of Every Greenlandic Glacier From 2000 to 2020
In Greenland, 87% of the glacierized area terminates in the ocean, but mass lost at the ice-ocean interface, or frontal ablation, has not yet been fully quantified. Using measurements and models we calculate frontal ablation of Greenland's 213 outlet and 537 peripheral glaciers and find a total...
