Greenland Ice Sheet mass balance and interactions with climate
My main current research activity involves using climatic and glaciological datasets and models, to estimate the present-day surface mass balance, and hence contribution to global sea-level change, of the Greenland Ice Sheet (eg Hanna et al, Journal of Geophysical Research - Atmospheres, 2005), in collaboration with partners in the USA (including NASA), Belgium, Denmark and University of Wales Swansea.
NEW PAPER JUST ACCEPTED IN JOURNAL OF CLIMATE ATTRIBUTING INCREASED RUNOFF AND MELT FROM GREENLAND ICE SHEET TO GLOBAL WARMING (see downloads)
An updated graph showing snow accumulation, runoff and SMB variations of the Greenland Ice Sheet 1958-2006 is shown below. Further aspects of this work are studying monthly-to-multidecadal Greenland climate-ice interaction and helping interpret recent airborne laser surveys of changing ice-sheet elevation and satellite maps of changing melt extent. A new interest lies in exploring links of Greenland mass balance changes with changes in Arctic sea-ice coverage.
