520 3# ‡aReports physical and biological investigations of perennial sea ice in summer 1994 in Bellingshausen and Amundsen Seas, and in summer 1997 in Weddell Sea. Proposes heuristic model of processes at surface of Antarctic sea ice from onset of summer melt to beginning of fall freeze-up. A total of 48 floes were visited. Reports stratigraphy of snow lying on sea ice and measurements of snow thickness, density, salinity, wetness and temperature. Describes coring and sampling of sea ice up to 5 m thick. Typical sequence is a snow layer above a surface ice layer overlying a slush- or sea-water-filled gap containing high algal standing stocks. Main ice below this is often extremely rotten and porous. Samples ice layer above gap with a high vertical resolution. Layer is evidence of considerable surface melting in Antarctic pack ice, strong enough to induce extensive snow metamorphism and the formation of superimposed ice (thickness reaches 0.25 m in NW Weddell Sea). Proposed model includes an abiotic explanation of initial gap formation. Discusses how sea ice processes affect radar backscatter. Contrasts conditions with those of Arctic summer, where ice growth is at base, rather than surface.
