Remote Sensing: A Method to Improve High-Resolution Sea Ice Drift Retrievals in the Presence of Deformation Zones.

Wolfgang Dierking and his colleague Jakob Griebel from the Alfred Wegener Institute (AWI) published a paper in “Remote Sensing” on the improved detection of narrow deformation structures in sea ice (with Jakob as first author). The major idea is to avoid blurring of discontinuities in the field of sea ice drift. Abstract: Retrievals of sea Read More
