Fast-ice Distribution in East Antarctica During 1997 and 1999 Determined Using RADARSAT Data
An image correlation technique has been applied to RADARSAT ScanSAR images from November in 1997, and November 1999, to create the first detailed maps of fast ice around East Antarctica (75E-170E). This method is based upon searching for, and distinguishing, correlated regions of the ice-covered oce...
