The influence of bathymetry and grounded icebergs on cross-shelf exchange in coastal Antarctica
Abstract:
Interactions between various water masses and ice shelves along the Antarctic coastline impact the global climate and sea level. This talk focuses on how geometric features such as bathymetric troughs and fast ice affect cross-shelf exchange and ice shelf basal melt rates in dense water formation regions of the Antarctic continental shelf. Using eddy resolving numerical ocean models, we find that mesoscale dynamics are important for buoyancy-driven cross-shelf exchange, and the location of grounded icebergs greatly influences the processes by which they impact regional hydrography and ice shelf melt. In addition to these results, Alan is happy to talk about his current research comparing CryoSat-2 interferometric radar altimetry-based to ICESat-2 laser altimetry-based estimates of ice shelf thickness.
