Animation of Subglacial Lake Behavior

 

 

Water moving between subglacial lakes can explain elevation changes in ice stream surfaces. This animation shows modeled behavior of subglacial lakes. Depending on the pressure of overlying ice, water can pool in unusual places. Unlike a water body with no ice overhead, a subglacial lake might form on the top of a hill if it is surrounded by ice that exerts tremendous pressure.
