While drilling holes in Alaska's Bench Glacier, scientists discovered dozens of massive cracks from the ground to the ice. The movement of water through the cracks could cause the glaciers to move or melting. The cracks hold a certain amount of water and could help scientists better predict how and when glaciers move and melt. Scientists need to figure out how wide the cracks are and how it could affect the sea level. Just a little of water could cause the pace of a hunk of ice to go faster. Scientists are trying to find out how much water is in a glacier, so that they can tell how much will the sea level rise and how much water there is.
