The contribution of West Antarctic Ice Sheet melt to sea level rise is identified as the largest source of uncertainty in the fifth assessment report of the Intergovernmental Panel on Climate Change. Nearly all the ice sheets in Antarctica terminate on the ice shelves (the floating extensions of the ice sheets) and ice shelf-ocean interaction is one of the most, if not the most, important scientific questions, when seeking to deliver a reliable projection of future sea-level rise. Thinning of ice shelves will reduce the restraints on the flow of grounded ice sheets upstream, thereby increasing the ice sheets’ contribution to sea-level rise. Many of the ice shelves in Antarctica have been thinning with accelerating rates, and the thinning is tightly coupled to increased oceanic heat fluxes.  Despite its importance, the dynamics governing the flow of warm water towards and into the ice shelf cavities are poorly understood and poorly represented in climate models.

I'm involved in projects aiming to quantify and better understand the oceanic heatflux towards Antarctic ice shelves. My work is mainly based on observations and focuses on the Weddell and the Amundsen Sea.
