Abstract:

Ice loss to the ocean due to phase change is a critical component of the ice sheet-ocean interaction but is challenging to model and quantify. Various theoretical and experimental studies have considered ice melt from vertical to nearly horizontal faces. They have revealed different behavior for the predicted melt rate under different dynamic conditions. However, the parameterization of existing models does not capture all relevant regimes of ice-ocean interactions. To advance towards improved models of ice-ocean interaction, we synthesize current findings and examine the parameterization of turbulent fluxes from the ocean to the ice, quantifying the melt rate.
