Members of the ice-ocean modeling community discussed and compared modeling approaches, capabilities, limitations and future goals at the Regional and Mesoscale Modeling of Ice Covered Oceans workshop, held near Bergen, Norway, October 23–27, 1989. The goal was to determine how well geophysical processes present in ice-covered oceans are understood and modeled, and to identify data from upcoming field investigations, including satellite remote sensing, that can be used to determine processes that crucially control climatic changes on seasonal or longer time scales. Sponsored by the International Association for Physical Sciences of the Ocean, the Office of Naval Research, and Rieber Shipping Ltd., the workshop attracted more than 60 attendees from the U.S., Canada, U.S.S.R., Japan, New Zealand, France, F.R.G., U.K., Italy, Finland, Sweden, Denmark and Norway.

Forty-two papers were presented in five separate sessions that addressed formation of eddies, jets and vortex pairs; marginal Ice Zone and interior ice dynamics; data blending and assimilation techniques in regionaloperational modeling of the Greenland and Barents seas; coupling of sea ice to atmospheric and oceanic boundary layers; and sea ice-ocean coupling in large-scale circulation models. The discussions that followed formal presentations in each session are summarized in this report.
