Research interests

Key research interests
  • Transit times and pathways of meltwater through the glacial hydrological system
  • Controls on crevasse propagation, moulin formation and the drainage of supraglacial lakes 
  • Working towards better implementation of hydrology within glacier and ice sheet models 
  • The role of meltwater in the dynamics and stability of palaeo ice sheets


Ongoing research projects

Hydrology and dynamics of the Eurasian Ice Sheets
– Main collaborators: Sarah Greenwood, Per Holmlund, Martin Jakobsson (Stockholm University) and Johan Nyberg  (Geological Survey of Sweden)

This research is focussed on an improved understanding of the retreat and dynamics of the Eurasian Ice Sheets during the Late Weichselian. I have a specific interest in the Baltic and Bothnian seas, and a combined modelling/geomorphology approach is being applied to help better constrain ice stream activity in this region. This includes investigating the controls on grounding line stability and flow dynamics, and the role of meltwater in driving retreat. Mapping of high-resolution bathymetric data provides a incredibly well-preserved insight into the subglacial environment in this area, from which we might better understand contemporary glacial processes. This work thus contributes to improving our understanding of both present day and palaeo ice sheets, and provides a unique perspective on marine-terminating ice streams.

 
Hydrocarbon pollution on Rabots Glacier, Kebnekaise, Northern Sweden
– Main collaborators: Gunhild Rosqvist and Jerker Jarsjö (Stockholm University)

In March 2012 a Royal Norwegian Air Force Hercules plane crashed just below the summit of Kebnekaise, depositing much of the wreckage and fuel onto Rabots Glacier. Through an ongoing monitoring programme we are investigating the transit pathways and likely lifetime of the hydrocarbon pollution within the glacier catchment. This includes how the pollutants behave in the snowpack, the use of dye tracers to investigate the likely transport pathways for pollution from the source zone, and detection of pollution in the proglacial environment where it enters a river used for drinking water by both animals and humans.
