Landsat's Global View of Ice Velocity
Ice from glaciers constantly flows into the ocean, but the speed the ice moves at changes. Landsat 8 provides near-real-time mapping of ice speed in nearly all the world’s frozen regions. Information like ice speed helps scientists study our home planet and its vulnerability to rising seas.
Heimdal Glacier in southeastern Greenland shows a regular speed up and slow down with the seasons. Peak speeds are around May/June, and low speeds occur in September/October.
This velocity data is a result of new analysis of imagery from the Operational Land Imager on the NASA/USGS Landsat 8 satellite, part of the Global Landsat Ice Velocity Extraction (GoLIVE) project.
