Antarctic ice melt is accelerating and contributes the largest source of uncertainty to 2100 global sea level rise estimates. The destabilisation of the Antarctic ice sheet is emanating from ocean-forced melting of the marine-terminating glaciers. Ocean currents bring warm waters southwards across the Southern Ocean towards Antarctica, driving basal melting of the ice shelves. However, due to sparse observations, the cause of the ocean warming is uncertain, and in fact we know very little about the distribution and sensitivity of the ocean currents around Antarctica. My research utilises eddy-rich global ocean-sea ice models to investigate ocean dynamics around Antarctica, and in this presentation I will describe some surprising results that have emerged from our simulations. We find that the warm water transport towards Antarctica is concentrated away from regions where the high rates of melt are observed. This is unexpected, because observations have primarily been targeting these high-melt regions. We also identify a negative feedback, whereby adding increased meltwater to the ocean causes regional cooling, which may slow future melt.
