Now, satellite data can help scientists measure the depth and shape of ice shelf fractures to better predict when and where calving events will occur, according to researchers. Ice shelves make up nearly 75% of Antarctica s coastline and buttress or hold back the larger glaciers on land, said Shujie Wang, assistant professor of geography at Penn State. If the ice shelves were to collapse and Antarctica s glaciers fell or melted into the ocean, sea levels would rise by up to 200 feet.
