Abstract :
A semi-automated sea ice mapping system has been developed for use by meteorologists responsible for providing information to Antarctic shipping on current sea ice conditions in the vicinity of the Antarctic stations at Casey, Davis and Mawson. The system uses AVHRR images from NOAA satellites and processes these images to identify areas of cloud, open water and sea ice. It further analyses sea ice regions to determine concentrations of sea ice found within these regions. The system is currently being used on a trial basis, at the Bureau of Meteorology in Hobart, to evaluate its effectiveness, prior to installation at the Casey station later in 1997
