SUMMARY:Antarctic subglacial hydrology - Anne Le Brocq (University of Durh
 am)
DTSTART:20081029T163000Z

CONTACT:Poul Christoffersen
DESCRIPTION:Investigations into the subglacial hydrology network beneath t
 he Antarctic Ice Sheet have shown that it is a dynamic system which is hig
 hly sensitive to small changes in the surface morphology.  However\, the r
 ole of subglacial water in controlling the dynamics of ice flow is not ful
 ly understood\, and hence a physically realistic numerical model of the An
 tarctic Ice Sheet does not presently exist.  This seminar will describe th
 e nature of Antarctic subglacial hydrology\, highlighting the locations wh
 ich may be highly sensitive to surface changes\, and discuss previous and 
 potential modelling efforts which have attempted to link the two dynamic s
 ystems.
