Canada Research Chair (Tier 2) in Glacier Hydrology and Ice Dynamics 

Christine joined the department following a postdoctoral fellowship at NASA Goddard Space Flight Center. Her research interests are focused on the development of subglacial hydrological networks and the impact of this on ice dynamics on a variety of spatial and temporal scales. She analyses these systems using a combination of numerical modelling methods and data integration.

Key areas of graduate supervision:

Numerical modeling, glacial hydrology, ice dynamics, glaciology data collection.

Research interests:

My research interests center in glacial hydrology and ice dynamics. In particular, I use numerical models of subglacial water flow combined with remote sensing and in situ data to determine the impact of hydrological development underneath ice sheets and valley glaciers on ice flow.

My current research has three primary themes:

  1. Using numerical models to assess stability of subglacial lakes in the Antarctic and their impact on the dynamics of fast-flowing ice streams. These large bodies of water accumulate and drain under the ice on scales of years to decades. I am also interested in the seasonal development of Greenland subglacial hydrological networks, particularly in regions of inland ice where the warming climate is allowing greater access of water to the bed of the ice sheet.
  2. Field-based data collection from surge-type glaciers in the Yukon. I go to my Yukon field sites several times a year and collect data from dGPS networks, time-lapse cameras and in situ hot water borehole drilling. These data are being applied to analysis of surging glacier dynamics and also hydrological modeling.
  3. Geophysical analysis of ice shelf stability in the Antarctic. I use aerial and ground-based geophysical data, along with remote sensing and modeling approaches to assess controls on ice shelf stability, which controls the rate of grounded Antarctic ice flow into the ocean, and therefore sea level rise.

Cumulatively, these research interests aim to answer questions about the future of glaciers and ice sheets in our changing climate and contribute to predictions of ice-climate feedbacks.

Potential graduate student projects:

I welcome inquiries from students interested pursuing a Masters or PhD in glacial dynamics. Current PhD topics include, but are not limited to:

  • Investigation of surging glacier dynamics in the Yukon Territory
  • Supraglacial hydrology modeling on ice sheets and valley glaciers
  • Assessing ice dynamic controls on fractures forming in Antarctic ice shelves
  • Modelling the impact of basal hydrology on grounding line stability in the Antarctic
  • Testing the applicability of subglacial hydrology equations using in situ data
  • Assessing subglacial sediment characteristics from glaciers in the Yukon Territory

Please contact me if you would like to discuss these projects or other potential avenues of research.
