ICE DYNAMICS IN THE CANADIAN ARCHIPELAGO AND ADJACENT ARCTIC BASIN AS DETERMINED BY ERTS-1 OBSERVATIONS

ERTS-1 "Quicklook" imagery for the period March to November 1973 has been utilized to study sea ice in the Canadian archipelago and adjacent Arctic basin. The imagery, which provides extensive coverage of the area of interest, contains detailed information on variations in sea ice dynamics and ice morphology on a time scale ranging from several days to seasons. Because of the sidelap of the ERTS-1 orbits over the study area, recognizable ice floes could be tracked on repetitive daily images for time periods as long as 6 days. Information on ice drift velocities, compactness, floe size, fast ice and ice melt patterns and dates of breakup and freezeup were obtained. Although details of the ice motion were complex, it was possible to delineate some general patterns such as the advection of ice southward through the islands of the archipelago toward Viscount Melville Sound, eastward out of Lancaster Sound, and westward out of Amundsen Gulf.
