DESCRIPTION:One of the largest uncertainties in forecasts of the melting i
 ce caps is the role played by water at the base of the ice in lubricating 
 ice flow. Recent observations of the Greenland Ice Sheet have shown that s
 ummer melt water penetrating from the ice surface substantially affects th
 e rate at which the ice slides\, while in Antarctica basal water plays a (
 presumably) controlling role in the dynamics of ice streams.  I will discu
 ss the latest attempts to model subglacial drainage\, focussing mainly on 
 the highly dynamic situation when surface melt water enters the ice.
