            "description": "For nearly a century, scientists have been studying the form and flow of the Greenland Ice Sheet.  They have measured the change in the elevation of the surface over time using satellites.  They have drilled ice cores in the field to reveal a record of what the past climate was like.   They have flown aircraft over the surface of the ice sheet laden with instruments to gleen information about the interior of the ice sheet and the bedrock below.  <br><br>Now a new analysis of this data has revealed a three dimensional map of the age of the ice sheet.  This visualization shows this new 3D age map of the Greenland Ice Sheet, explains how it was created and describes the three distinct periods of climate that are evident within the ice sheet.<br><br>More information is available <a href=\"http://www.nasa.gov/content/goddard/nasa-data-peers-into-greenlands-ice-sheet/\"> here.</a>",

            "description": "For nearly a century, scientists have been studying the form and flow of the Greenland Ice Sheet. They have measured the change in the elevation of the surface over time using satellites. They have drilled ice cores in the field to reveal a record of what the past climate was like. They have flown aircraft over the surface of the ice sheet laden with instruments to gleen information about the interior of the ice sheet and the bedrock below.Now a new analysis of this data has revealed a three dimensional map of the age of the ice sheet. This animation shows this new 3D age map of the Greenland Ice Sheet, explains how it was created and describes the three distinct periods of climate that are evident within the ice sheet. || ",
