133 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.
