"In the context of climate change, we need to understand the characteristics of the bed, because they exert a very powerful control over the flow of the glacier," he said.PhD student Madi Gamble Rosevear said the speed at which the Totten Glacier travels was determined by what it moved across."As the glacier flows over the land, the properties underneath it control how quickly it flows," she said.
It matters because could affect the rate the glaciers move into the ocean - leading to faster sea rise
"The Totten Glacier drains an area of east Antarctica that contains about seven metres of sea level rise equivalent of ice,"
