Record #118779:

Sea ice melting and floe geometry on a simple ice--ocean model / Michael Steele.

Title: Sea ice melting and floe geometry on a simple ice--ocean model / Michael Steele.
Author(s): Steele, Michael.
Date: 1992.
In: Journal of Geophysical Research. (1992.), Vol. 97(C11) (1992)
Abstract: Model contains diagnostic equation for average floe diameter in addition to prognostic equations for ice volume per unit area and ice concentration. Partition between melting on top, bottom, and lateral (side) surfaces of floes is examined using time-dependent simulations with differing initial average floe diameters. Different parameterizations for published bottom and lateral melting are also compared and found to vary significantly. Results show that lateral melting is important only for floes with diameters <30 m, given atmospheric thermal forcing typical of central Arctic in summer, which means that decrease in ice concentration over summer is strong function of floe diameter. In all cases, about 80% of net thermal energy entering ocean through leads goes towards melting ice, and remainder warms ocean.
