“Ice-Track”: Providing High-Resolution Sea Ice Type Forecast for Route Optimization
Spaceborne Synthetic Aperture Radar (SAR) images are well suited for navigation assistance through ice covered waters due to their all-day and all-weather capability. For Arctic campaigns of RV Polarstern, SAR images are acquired and automatically delivered onboard. However, at the time of delivery...
