Environment Counts | Fluctuations in the Cryosphere – NASA/Goddard Visualization :
The Scientific Visualization Studio at NASA/Goddard Space Flight Center has produced a video animation showing fluctuations in the cryosphere over time. Most of the data and satellite imagery is from 2009, but it includes satellite images and graphical markers of some major events and changes from 2000 and earlier. The Tour of the Cryosphere 2009 starts in Antarctica and moves north providing coverage of major relevant areas including Greenland and the Arctic Ocean and neighbouring land/ice masses. Imagery includes changes in the Ross Ice Shelf along with imagery of the collapse of more than 3,200 sq km of the Larsen ice shelf since January 2002. A link is provided to the Landsat Image Mosaic of Antarctica (LIMA, which is useful although no longer actively maintained). Notes introducing the visualization provide links to relevant data and satellite imagery sources.
