Antarctic continental shelf break (shapefile)

Antarctic continental shelf break in shapefile format based on IBCSO v. 1.0 (Arndt et al., 2013), manually digitised at a spatial scale of 1:300,000. It is created with the guidance of bathymetric contours at 50 m intervals and slope-gradient maps. In areas permanently covered by ice, the shelf break is linearly interpolated between the two closest ice-free points.
