Description:
Abstract:
The team used data from NASA’s high-resolution ICESat (Ice, Cloud and Land Elevation Satellite). Launched in January 2003, ICESat was sent into a polar orbit to examine changes in the world's ice and land masses — particularly ice mass balance — as well cloud and aerosol height. The satellite’s lasers have measured the surface elevation of the Earth’s ice sheets with unprecedented accuracy. The satellite’s repeated passes over both poles create a wide net of coverage, and contribute to a long-term time series of topographic changes. For the first time scientists can see the elevation change over the whole of the Antarctic Peninsula, and that glaciers in this area have the highest rates of thinning recorded in Antarctica or Greenland. * 43 million satellite measurements of the Antarctic and 7 million of Greenland over a 5 year period (2003-2007)
