Popis: sphere is complicated by numerous land masses which largely confine it during the winter to the Sea of Okhotsk and to the Bering, Labrador, and Greenland-Norwegian seas. During the spring and summer the MIZ retreats from the peripheral seas. Generally, the total extent of the northern MIZ is less than one-half that of the southern. Numerous studies have demonstrated the sensitivity of weather and climate to the state of the polar ice cover, and it is of fundamental importance to understand how annual and interannual variations in ice extent are related to large-scale and mesoscale circulations in the atmosphere and ocean. Successful modeling and parameterization of processes which govern the location and state of the MIZ are important not only for predicting the impact of sea ice on global climate but also for furthering man's activities in the MIZ regions (e.g., offshore oil exploration, seaborne transport of Arctic resources, development of the rich fisheries close to the ice margin, and naval operations). In recent years, realization of the scientific and economic significance of the MIZ has focused attention on the need for coordinated, multidisciplinary studies of conditions and processes near ice-open ocean boundaries, and has led to the development of the Marginal Ice Zone Experiment (MIZEX). Although of substantial interest, the remoteness of the vast Antarctic MIZ poses serious logistic difficulties, and MIZEX efforts to date have concentrated on the more accessible northern MIZ. Considerable work has been carried out in the
