Landsat Illustrates Five Decades of Change to Greenland Glaciers
28 August 2019
Ice fronts have retreated, rocky peaks are more exposed, fewer icebergs drift to the ocean: the branching network of glaciers that empty into Greenland's Sermilik Fjord has changed significantly in the last half century. Comparing Landsat images from 1972 and 2019, those changes and more come into view.
The glaciers appear brownish grey in this true-color Landsat 8 satellite image from Aug. 12, 2019. The color indicates that the surface has melted, a process that concentrates dust and rock particles and leads to a darker recrystallized ice sheet surface.
