Title: Fast-ice Distribution in East Antarctica During 1997 and 1999 Determined Using RADARSAT Data
Description:
Abstract:
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.
