Description / Table of Contents:
A computer technique is described for digitising data from the sea ice maps distributed weekly by the U.S. Navy-NOAA Joint Ice Centre. Monthly maps of the Antarctic region outlining extent of sea ice cover have been available from this source since January 1973. Computer programs for the analysis of this data are described. Maps are presented which illustrate the mean, over ten years, of the extent each month and at maximum. These data have been used as climate monitor using the relation between sea ice extent and the distribution of anticyclones, Antarctic and ocean temperatures, and atmospheric CO2 levels which have been the topics of many recent studies. The data are also of revelance to polar transport studies. Ships may need to penetrate, and aircraft may need to overfly, many kilometre of sea ice in order to carry out scientific programs or to gain access to Antarctic stations.
