Abstract :
In February 2003, sea ice thickness measurements using an electromagnetic induction (EM) instrument were made in the Gulf of Bothnia and Gulf of Finland. We have made comparisons between the EM measurements and Radarsat-1 ScanSAR Wide mode SAR data, and also between our operational sea ice products (digitized ice thickness charts, and ice thickness charts refined by the latest Radarsat-1 image). The SAR images are in 100 m resolution, and the other products are in 500 m resolution
