Abstract: A PRAM IV laser profiling system, a video camera and a Hasselblad 70 mm camera were used to study ice conditions near the ice margin in the eastern Weddell Sea, Antarctica. The sensor combination offers some interesting analytical possibilities. Digital elevation models of the ice surface, and ice block, ridging and other statistics may be produced without need for supporting ground surveys. The field work was carried out during the period December 29,1989 to January 5,1990 and the data thus represent the time of year when most shipping activity takes place in this region. This paper describes the techniques used in the data acquisition, outlines the analytical procedures and presents some preliminary results. These preliminary results indicate that ridge size and frequency are greater in the Weddell Sea than in the Ross Sea.
