Abstract

A coupled ice-ocean model is presented for the short term (order days) prediction of ice floe movement in shallow waters. In addition to the explicit treatment of the feedback between the ice and water systems, the formulation includes finite depth effects such as bottom friction and sea surface gradient. We present arguements for the use of an advection-diffusion equation in the determination of the sea ice concentration, thereby accounting for the small scale, random fluctuations unreasolvable by practically feasible model timesteps. This equation is solved by the Eulerian-Lagrangian method. Model comparisons with the measured drift tracks of two ice floes in the Beaufort Sea are extremely encouraging.
