What is the Cryosphere?
When scientists talk about the cryosphere, they mean the places on Earth where water is in its solid form, frozen into ice or snow. Read more ...

The R/V Aaron traverses Beascochea Bay during the 2013 LARISSA Project. The Larsen Ice Shelf System, Antarctica (LARISSA) Project is a large, interdisciplinary, multi-institute study to explore every aspect of the deteriorating Larsen Ice Shelf region in Antarctica. Participating researchers set up instruments on the glaciers that feed into the remaining portion of the Larsen ice shelf. As changes occur on the ice, the stations will record it in data and pictures. (Credit: Ted Scambos, NSIDC) Read the expedition blog on http://iceshelf.wordpress.com. (View photo detail.)
