Abstract : An outlook of sea ice conditions expected in the Ross Sea and McMurdo Sound regions of Antarctica is presented for the period mid-December 1969 through mid-February 1970. Oceanographic and climatic data for these areas were analyzed in terms of sea ice growth during the past austral winter. These analyses, combined with ice conditions observed by aerial reconnaissance on 2 and 18 November and by satellite for the period 11 through 18 November and a comprehensive study of historical ice and climatic information, formed the basis for the 1969-70 Ice Outlook. In summary, heavy ice conditions were observed in the Ross Sea and light conditions and a near-normal extent of fast ice were observed in McMurdo Sound on the preliminary aerial reconnaissance. Ice conditions are expected to be lighter in McMurdo Sound and heavier in the Ross Sea in comparison to the 1968-69 season. (Author)
