    Abstract

    The position of the sea ice edge around the Antarctic continent was digitised into MAPINFO GIS software from the Joint Ice Centre weekly charts of sea ice distribution. The digitised images were then used to calculate the distance of the ice edge from CEMP sites throughout the year. These data are used to construct several of the indices associated with CEMP Environmental Monitoring Method F2: sea ice.
