Institute of Geography Modelling the Hydrology of the Greenland Ice Sheet Mehmet Karatay Institute of Geography Supervisors: Nick Hulton Pete Nienow

Greenland 16% 84% Freshwater injection some models predict icesheet disapearing hyrology=>dynamics=>better predictions left: http://www.ggy.bris.ac.uk/images/Greenland%20topo.gif

Future of Greenland thining predictions – pete's drawing etc. has this happened before? the significance of this sea level rises oceanic circulation top left: http://cires.colorado.edu/science/groups/steffen/ right: NASA Earth Observatory top left: Steffen Research Group, University of Colorado at Boulder bottom left: http://www.nasa.gov/vision/earth/lookingatearth/jakobshavn.html

Investigation methods a greenland dem here to compare to modelling http://www.ulapland.fi/home/hkunta/jmoore/okstinden_images.htm

The Modelling EISMINT image EISMINT: Ice Thickness EISMINT: Basal Melt EISMINT image talk about stages in work including darcian flow

Conclusion Greenland plays a key role in future climate change Understanding the hydrology will give us a better understanding of how Greenland may react Modelling can provide insights into this
