Ice Motion

The Scanning Multichannel Microwave Radiometer (SMMR), Special Sensor Microwave Imager (SSM/I), and Advanced Microwave Scanning Radiometer - EOS (AMSR-E) instruments have all in turn been in earth orbit for a number of decades on a variety of platforms, taking measurements of the brightness temperatures of the Earth’s polar regions on a near continuous basis. This long satellite data record has provided the ability to estimate sea ice motion since 1979 to the present. In this project the imagery created from these measurements is used to track sea ice features and produce mean ice motion fields down to a daily time scale.

These ice motion fields are being used to characterize a variety of dynamic processes occurring in the polar regions, including the estimates of sea ice exchange between the Arctic Ocean and the peripheral seas, the transfer of mass within the Arctic Ocean system (Graphics), and the formation of polynyas off the large ice shelves of Antarctica.
