IBCSO Multibeam Footprint The IBCSO group also tries to improve multibeam data acquisition in the future by providing information about the current multibeam coverage in the Southern Ocean. The IBCSO SID can be used to determine where multibeam data has already been surveyed. For an easier access to this information we also provide a GIS ready shapefile showing the outline of multibeam surveys as of IBCSO V1.0 here Arndt, J.E., H. W. Schenke, M. Jakobsson, F. Nitsche, G.
