Lunar Prospector / Neutron Spectrometer


Multimedia Items Available Relating to Lunar Prospector / Neutron Spectrometer
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
