Research

My research primarily aims at improving the understanding of the basal mechanics of glaciers and ice streams in Antarctica and Greenland. In particular, I study how their effect on bed resistance controls the short and long-term variability of ice flow.

I am modelling ice flow dynamics in Greenland as part of the SAFIRE and RESPONDER projects, aiming at a better understanding of the short and longer-term response of ice flow, when large volumes of surface meltwater reach the glacier’s bed each summer. To do so, I integrate data recently collected at the base of Store Glacier (Western Greenland) into a model of basal processes coupled to the community ice sheet model CISM 2.0. For these projects, I focus on how the input of surface meltwater to the bed changes the speed of the glacier’s flow, mainly from altering the thermal energy balance near the base, and from interacting with subglacial sediments found beneath Store Glacier.

As part of the iSTAR programme, I recently investigated the role of subglacial processes in the persistent acceleration of Pine Island Glacier, a fast-flowing glacier located in West Antarctica and currently responsible for 20% of its total ice loss. Due to high frictional heat production, water exist in abundance at the base of Pine Island Glacier. Using multiple inversions of observed surface velocities, it is possible to infer changes in the production and distribution of water for the entire basin, and to furthermore establish a link with the evolution of bed strength beneath the glacier. Overall, this work aims at a better understanding of subglacial hydrological controls on fast flowing glaciers of Antarctica.
