Barotropic tides beneath the Amery Ice Shelf



Barotropic tides beneath the Amery Ice Shelf



Journal of Geophysical Research 111(C11, 2006



A barotropic tidal model has been applied to the Amery Ice Shelf cavity and Prydz Bay region of East Antarctica. The sensitivity of the tidal solution of the model to variation of the water column thickness of the Amery Ice Shelf cavity has been determined. A best estimate water column thickness grid is presented which both fits available water column thickness data (bed elevation and ice thickness) and results in reasonable agreement with available tidal elevation data. This is an important result for the Amery Ice Shelf given the severe lack of sub-ice shelf bed elevation and limited direct ice thickness measurements. Using the resulting topography, simulated tidal current speeds in the sub-Amery Ice Shelf cavity are significantly less than those beneath other major embayed Antarctic ice shelves. Similarly, the estimated energy dissipation beneath the Amery Ice Shelf due to surface friction of 6 MW is low in comparison with the other ice shelves. (mod. journ. abst.).
