Physical Processes Related to Sea-Ice Divergence
This report documents the results of a study of a number of sea ice processes in the Arctic Basin. Seasonal sea ice kinematics were closely scrutinized, and their space and time scales calculated. Factors concerning sea ice thermodynamics were also considered. Direct comparisons were made between ob...
