Glacier Mass Balance/Ice Sheet Mass Balance


GCMD >> EARTH SCIENCE >> Hydrosphere >> Glaciers/Ice Sheets >> Glacier Mass Balance/Ice Sheet Mass Balance
Movie ID Title
ICESat elevation data taken on June 2, 2006 is shown in orange. The underlying gray 'shadow' corresponds to where the elevation data lies on the surface. The underlying MODIS data is a 3 day average taken in the month of December 2005. 3403 Antarctic Plumbing: Lake Englehardt's Subglacial Hydraulic System

GCMD >> EARTH SCIENCE >> Cryosphere >> Glaciers/Ice Sheets >> Glacier Mass Balance/Ice Sheet Mass Balance
Movie ID Title
The mass changes of the Gulf of Alaska glaciers are computed from the Gravity Recovery and Climate Experiment (GRACE) inter-satellite rate data from April 2003 through September 2007. Using space-borne gravity measurements to assess glacier mass balance NASA scientists determine mass variations along the Gulf of Alaska, an area apanning 18,919 square miles. Areas of deep blue like the areas around Glacier Bay and the Yakutat Icefield represent significant mass loss where inland areas of dark gray represent slight mass gains. 3522 Recent Glacier Mass Changes in the Gulf of Alaska Region from GRACE Mascon Solutions
