This video segment, adapted from a NOVA broadcast, continues the broadcast 'Antarctic Ice Movement'. This portion explains the phenomenon of ice streams, areas of fast-moving ice flow, and shows a team of scientists seeking evidence to support their hypothesis that atmospheric warming, either now or in the past, may explain why water has formed beneath the ice sheet, creating a lubricating layer of water and mud to speed up the flow of ice. The segment is five minutes fifteen seconds in length.
