Responses of the Beaufort Sea and Canada Basin icc pack to the passage of synoptic-scale weather systems are studied using Synthetic Aperture Radar (SAR), Advanced Very High Resolution Radiometer (AVHRR) and Special Sensor Microwave/Imager (SSM/I) data combined with ice model simulations. Changes within the consolidated ice pack are examined in detail for October 1991. The analysis is then extended to consider general conditions from October 1991 to June 1992. The SAR, SSM/I, and modelled concentrations concur generally, showing a 1-5 per cent decrease in ice fraction during the passage of low-pressure systems through the study area. The AVHRR imagery indicates a greater proportion of thin ice within the pack, but comparable decreases in concentration. While changes in SSM/I-derived open-water fractions are similar to changes in the other data sets, the SSM/I data suggest substantial increases in first-year ice concentration, indicative of the formation of refreezing open water areas. Sensible heat fluxes calculated using open-water and ice-type fractions from the SAR and SSM/I imagery point out the sensitivity of heat transfer estimates to, the data types and classification method used to derive ice information. |
