As regions of Antarctica undergo rapid melting, the inflow of freshwater leads to global sea level rise, but what exactly is Antarctica’s contribution ?
Current satellites cannot measure ice discharge directly, but they can be used to observe processes on the surface, including, how the ice bends up and down with the tides as it flows from the continent into the ocean. Measuring this surface bending along the Antarctic coastline can then indirectly determine the ice flow underneath, but this connection requires knowledge of the physical properties of ice. My research targets these properties by combining satellite observations with numerical modelling and field measurements of tidal bending to estimate the contribution of Antarctica to global sea-level rise and its impact on coastal communities in an ongoing climate change.
