THE BASAL MELTING OF ANTARCTIC ICE SHELVES . The project aims to determine the mechanisms that govern melting of Antarctic ice shelves into the ocean. Faster basal melting of ice shelves in the warming ocean is contributing to loss of grounded ice from Antarctica and increased glacier speeds, and melting is projected to become a larger contribution to future global sea level rise. Using unique laboratory experiments, turbulence-resolving computation and theoretical analysis the project will eva ....THE BASAL MELTING OF ANTARCTIC ICE SHELVES . The project aims to determine the mechanisms that govern melting of Antarctic ice shelves into the ocean. Faster basal melting of ice shelves in the warming ocean is contributing to loss of grounded ice from Antarctica and increased glacier speeds, and melting is projected to become a larger contribution to future global sea level rise. Using unique laboratory experiments, turbulence-resolving computation and theoretical analysis the project will evaluate the roles of meltwater, ocean currents, internal wave breaking and water exchanges between the continental shelf and sub-ice cavities. The results will assist our understanding of measurements made in Antarctica and more reliable predictions of sea level rise.Read moreRead less
Connecting ocean tides to the large-scale ocean circulation. This project aims to investigate the impact of tides on the ocean circulation and future climate change by combining new theory with next-generation numerical ocean models. The expected outcomes include ocean model configurations that will improve estimates of key processes affected by tides, such as Antarctic ice shelf melt rates, ocean warming and the ocean's overturning circulation. The project is thus anticipated to provide signifi ....Connecting ocean tides to the large-scale ocean circulation. This project aims to investigate the impact of tides on the ocean circulation and future climate change by combining new theory with next-generation numerical ocean models. The expected outcomes include ocean model configurations that will improve estimates of key processes affected by tides, such as Antarctic ice shelf melt rates, ocean warming and the ocean's overturning circulation. The project is thus anticipated to provide significant benefits in predicting future climate change, sea level rise, coastal erosion and marine heatwaves. Furthermore, it will enable the Australian and global communities to better target conservation and mitigation efforts, and thus reduce the environmental, social and economic impact of climate change.Read moreRead less
