A numerical model for the simulation of sea ice circulation and thickness over a seasonal cycle is presented. This model is used to investigate the effects of ice dynamics on Arctic ice thickness and ...
An Analysis of Arctic Sea Ice Fluctuations, 1953–77
Arctic Sea Ice Fluctuations polar cap digitized data
2009/2/13
Arctic sea ice data from the 1953–77 period are digitized onto a set of 300 monthly grids covering the polar cap. Each grid contains 1648 ice concentration points at a spacing of 1° latitude (60 n mi)...

Weddell Polynya Sea Ice Simulation
2009/2/5
Occurrence of the Weddell polynya, a large open-water area in the midst of the wintertime pack ice of the southern ocean, is examined through a sequence of numerical simulations of the sea ice cover. ...
A Heat Balance for the Bering Sea Ice Edge
marginal ice zone Marginal Ice Zone Experiment Heat Balance
2009/1/16
Detailed oceanographic, meteorological and sea ice observations were obtained from the Bering Sea marginal ice zone (MIZ) during the February–March 1983 Marginal Ice Zone Experiment (MIZEX West). Thes...

Hibler's dynamic-thermodynamic sea ice model with viscous-plastic rheology is used to simulate the seasonal cycle of sea ice motion, thickness, compactness, and growth rate in Hudson Bay under monthly...
Effect of Sea Ice on the Salinity of Antarctic Bottom Waters
Antarctic Bottom Waters Sea Ice
2008/12/12
Brine rejection during the formation of Antarctic sea ice is known to enhance the salinity of dense shelf waters in the Weddell and Ross Seas. As these shelf waters flow off the shelves and descend to...
The large-scale two-dimensional rheology of a sea ice pack arises from the local contact forces between adjacent does in convergence. It is conventionally modeled by a viscous-plastic constitutive rel...
As sea ice is advected on the surface of the ocean, the ice concentration (0 A 1) and the mean ice thickness change in response to thermodynamic and mechanical forcing. In this paper the authors rev...
