Abstract
The thermodynamic ice model of Thomdike (1992) is coupled to a one
dimensional, two layer ocean entrapment model to study the effect of mixed layer
dynamics on ice growth and the variation in the ocean heat flux into the ice due to
mixed layer entrapment. Model simulations show (i) the existence of a negative
feedback between the ice growth and the mixed layer entrainment; and (ii) the
underlying ocean salinity has a greater effect on the ocean heat flux than does
variations in the underlying ocean temperature. Model simulations for a variety of
surface forcing and initial conditions demonstrate the need to include mixed layer
dynamics for realistic ice prediction in the Arctic.
