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 ocean which remain stationary, in contrast to adjacent moving pack ice. Within the overlapping longitudinal range of ~86E-150.6E, the total fast-ice area is 141,450 km2 in 1997 and 152,216 km2 in 1999. Calibrated radar backscatter data are also used to determine the distribution of two fast-ice classes based on their surface roughness characteristics.


The outer boundaries of the determined fast-ice area for November in 1997 and 1999 are contained in the data files for this record.


This work has been allocated to ASAC project 3024.
