A box model study of the Greenland Sea, Norwegian Sea, and Arctic Ocean /
A simple box model of a a high-latitude two-layer ocean, first developed by Martinson et al., 1981, is applied to four Arctic regions connected together: the Greenland Sea, the Norwegian Sea, the Arctic Ocean, and the Greenland Gyre. The latter, in fact, is a small convective region embedded in the...

A simple box model of a a high-latitude two-layer ocean, first developed by Martinson et al., 1981, is applied to four Arctic regions connected together: the Greenland Sea, the Norwegian Sea, the Arctic Ocean, and the Greenland Gyre.

The model for each region consists of a thermodynamic ice layer that covers two layers of salty water which can, under specific conditions, become statically unstable and hence create a state of active overturning. The system is forced by monthly mean atmospheric temperatures in the four regions, as well as by continental runoffs and by inflows from adjacent oceans.
