77 viewsScientists observe closely spaced crevasses on Scar Inlet Ice Shelf during the 2013 LARISSA Expedition. The crevasses could fill with melt water during the next warm summer, leading to a possible disintegration event as happened to the main Larsen B in 2002. 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.

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.
