| Summary: | The U.S. Navy has a long and colorful history of polar exploration and currently is an active participant in growing national activity in the Arctic and Antarctic. The strategic importance and increased demand for the natural resources of these areas has resulted in a greater requirement for environmental information. Until a few years ago, reliable sea ice information in the polar regions was based on a relatively few shore station and ship reports augmented by limited aerial reconnaissance data. These data were further restricted to the relatively small areas observed primarily during the ship operating season. The principal aim of this publication is to provide operators and researchers with historical weekly hemisphere analyses of sea ice conditions derived principally from satellite imagery supplemented by conventional observations. The advent of high resolution satellite imagery combined with the ground truth of conventional observations has in recent years provided description of the polar ice fields on a semi-synoptic scale. Since 1970, the Fleet Weather Facility at Suitland, Maryland has prepared operational analyses and forecasts of ice conditions in the Artic and Antarctic for the Department of Defense and various other users. The results of these efforts are contained herein. (Author) |
