Over the past forty years a small increasing trend in Antarctic sea ice extent has been observed that is the sum of stronger, but opposing, regional and highly seasonal trends. The seasonality of the trends implies the role of feedbacks in modulating the observed trends. A highly simplified coupled sea ice—mixed layer model has been developed to investigate the importance of sea ice–ocean feedbacks on the evolution of sea ice in two contrasting regions of the Southern Ocean: the Amundsen Sea, which has warm shelf waters and a diminishing sea ice cover; and the Weddell Sea, which has cold saline shelf waters and an expanding sea ice cover.
