            "description": "The NASA/USGS Landsat 8 mission has allowed new views of the Earth’s glaciers.  By tracking displacement of local surface features through the seasons on outlet glaciers from the large ice sheets, researchers from the University of Alaska, the University of Bristol, and the University of Colorado have been able to show that each glacier around Greenland has a unique pattern of flow variation through the seasons.  Seasonal variations, seen in this animation on the lower 25 kilometers of Heimdal Glacier in southeast Greenland, are caused by a combination of processes.  For Heimdal, the largest forcing for flow variation is likely the input of increasing amounts of surface melt water through the Spring and Summer, but there is also an interplay between calving of ice from the end of the glacier, flow acceleration as shown in the animation, and thinning of the ice due to the extra stretching from the faster flow.  By measuring these changes in flow on seasonal timescales, scientists can develop a better understanding of what controls the flow of these glaciers where they meet the ocean.  This understanding will improve our ability to anticipate flow responses of these systems in a warming climate. || ",

            "description": "Since the late 1970's, NASA has been monitoring changes in the Greenland Ice Sheet. Recent analysis of seven years of surface elevation readings from NASA's ICESat satellite and four years of laser and and ice-penetrating radar data from NASA's airborne mission Operation IceBridge shows us how the surface elevation of the ice sheet has changed.The colors shown on the surface of the ice sheet represent the accumulated change in elevation since 2003. The light yellow over the central region of the ice sheet indicates a slight thickening due to snow. This accumulation, along with the weight of the ice sheet, pushes ice toward the coast. Thinning near coastal regions, shown in green, blue and purple, has increased over time and now extends into the interior of the ice sheet where the bedrock topography permits. As a result, there has been an average loss of 300 cubic kilometers of ice per year between 2003 and 2012.This animation portrays the changes occurring in the surface elevation of the ice sheet since 2003 in three drainage regions: the southeast, the northeast and the Jakobshavn regions. In each region, the time advances to show the accumulated change in elevation from 2003 through 2012.—><!——><!—Above: Move bar to compare the change in surface elevation (left) to the bedrock topography (right) in the northeast region.

            "description": "Subglacial topography plays an important role in modulating the distribution and flow of meltwater beneath the ice known as basal water flow. This animation portrays topographic data of the bedrock under the Greenland ice sheet derived from ice-penetrating radar data. Clearly evident in the topography is a 750-km-long subglacial canyon in northern Greenland that is likely to have influenced basal water flow from the ice sheet interior to the margin. The authors suggest that the mega-canyon predates ice sheet inception and has influenced basal hydrology in Greenland over past glacial cycles. (See reference under \"Science Paper\" below)Starting with a view of the surface of Greenland, the animation zooms closer to the surface as the ice sheet is stripped away to reveal the false-color topography of the bedrock that lies beneath. Regions above sea level are shown in shades of green while areas below zero are colored by shades of brown. Yellow indicates the area near sea level. The topography is exaggerated from 12 to 40 times in order to accentuate the topographic relief. Visible in the topography from about the midpoint of Greenland to its Northwest coast is the 750-km-long subglacial canyon described by the authors. || ",

In the east, these glaciers make their sinuous way through complex terrain at low speed. They form long floating extensions that deform slowly in the cold north. As we move toward sectors of higher snowfall in the northwest and centre west, ice flow speeds increase by nearly a factor 10, with many, smaller glaciers flowing straight down to the coastline at several kilometers per year.This complete description of ice motion was only made possible from the coordinated effort of four space agencies: the Japanese Space Agency, the Canadian Space Agency, the European Space Agency, and NASA's Jet Propulsion Laboratory.
