The broad theme of my research is studying the often complicated array of dynamic processes that affect the evolution of ice sheets and glaciers and how they interact with and respond to past, present and future climate change. One of the ice sheet processes that my research targets is improving our understanding of the mechanics of iceberg calving- a process that accounts for up to two thirds of the mass discharged from the cryosphere to the ocean. Not only does this have important implications for century time-scale sea level rise, but because fractures can propagate very quickly, iceberg calving introduces a “fast” time-scale into the response of the ice sheets to climate change that is not accounted for in numerical models.
