Profile

Biography

David joined the the Environment Department in October 2010.  Prior to that, he did his first degree at the University of Birmingham (B.Sc. 1st Class Hons.), before gaining a Ph.D. from the University of Cambridge.  He then worked as a post-doctoral researcher at the Universities of Bristol and Leeds, before becoming an RC-UK (Research Councils of the United Kingdom) Academic Fellow at the University of Hull, and then moving to York.

David is a glaciologist, and his research interests are focussed on the controls on the dynamics of glaciers and ice-sheets, and the use of ground-based and airborne radio-echo sounding (RES) techniques in exploring englacial and subglacial environments.  He also works on the thermal evolution of small Arctic glaciers, and is increasingly interested in supraglacial environments, and devising approaches for monitoring change in these locations.

David has carried out fieldwork in Antarctica, Svalbard (Norwegian High Arctic), Northern Sweden, Iceland and various alpine locations.  He is has been a Scientific Editor of the Journal of Glaciology since 2009, and has been a member of the NERC Peer Review College since 2010.

Research

Overview

David was an RC-UK (Research Councils of the United Kingdom) Academic Fellow at the University of Hull Geography Department before coming to York in 2010.  His research interests are focussed on the controls on the dynamics of glaciers and ice-sheets, and the use of ground-based and airborne radio-echo sounding (RES) techniques in exploring englacial and subglacial environments.  He is also increasingly interested in supraglacial environments – specifically the role of supraglacial debris on energy and mass balance (and the use of remote techniques for assessing debris thickness) and the role of surface water on energy balance.  He is editor of the Journal of Glaciology.

Using radio-echo sounding (RES) data to investigate the role of bed roughness in controlling areas of fast flow in Antarctica and Greenland

I am interested in using radio-echo sounding (RES) data to investigate the role of bed roughness in controlling areas of fast flow in Antarctica and Greenland.  Bed roughness is important because the degree of coupling between ice and bed is of fundamental significance in controlling the amount of basal motion taking place.  This coupling is controlled by bed roughness and subglacial water pressure, but bed roughness is often overlooked because of difficulties in measuring this quantity.  Deriving roughness measurements however, can prove to be a useful approach for identifying regions of current and relict fast flow, with implications for ice sheet stability.
