Blog #4

    

Researches had found out that there were deep cracks of the ice in the southern Alaska’s Bench Glacier. So the scientist are trying to find out how much water is contained in the crack. Depending how the crack size is will tell how much the sea level will rise in the distant future. The cracks, some of which are 80 meters deep. There is probably more water hidden in those cracks. A team Led by Joel Harper went and drill holes through Bench Glacier’s to about 200 meters of solid ice so they can see how the holes would drain. The team drilled many holes in the glacier to find out how much water was in the crevasses and so in the cracks there was enough water to cover the whole glacier to a depth of 10 cm. And so it depends how much the Earth's sea level to rise if you know the amount of water there are in the cracks of the glaciers in southern Alaska’s Bench Glacier, we'll just see in the future what will happen after the glacier melts.
