Ocean Ice There

- Project Launched to Better Detect Ocean Ice Hazards Marine Technology, Nov 2013 #56
There is an increasing need for fine scale detection and characterization of hazardous ice conditions in the Arctic. ASL Environmental Sciences Inc. has recently received funding from the Canadian Space Agency to address this need under the Earth Observation Applications Development Program. The project will develop improved techniques, tools and data products that will enhance the detection and characterization of hazardous ice conditions at fine scales, based on advanced beam modes of RADARSAT-2, and the unique capabilities of moored, upward looking sonar technology.
ASL’s Ice Profiler along with Acoustic Doppler Current Profilers will provide validation data and opportunities for improvement in the analysis and interpretation of the SAR imagery. In effect, this project will combine the view of the ice canopy from below (Ice Profiler) with the view from above (RADARSAT-2 high resolution quad-polarized data), and generate enhanced ice information products. Using simulated data for Radarsat Constellation Mission compact polarimetry beam mode, the operational utility of such products will also be assessed.
