New scientific discoveries regarding the Petermann Glacier
This image, acquired by one of the Copernicus Sentinel-2 satellites on 22 October 2022, shows the Petermann Glacier, one of the largest glaciers in Greenland.
Scientists monitor Pettermann due to its rapid retreat and calving events. A recent study has revealed a concerning new melting source. The glacier's grounding line, where the ice sheet extends over the ocean, can shift significantly with the daily tides. This previously unaccounted-for phenomenon could contribute to faster melting of the glacier and accelerate sea-level rise, as Greenland's melting ice is a significant contributor to global rising sea levels.
Copernicus enables glacier monitoring by utilising satellite data to track changes in glacier extent, ice thickness, and movement.
