The International Bathymetric Chart of the Southern Ocean (IBCSO) is a regional mapping project of the General Bathymetric Chart of the Ocean (GEBCO) operated under guidance of the UNESCO Intergovernmental Oceanographic Commission (IOC) and the International Hydrographic Organization (IHO). Moreover, IBCSO is established as an expert group of the Scientific Committee on Antarctic Research (SCAR) and its production is located at the Alfred Wegener Institute for Polar and Marine Research (AWI) in Bremerhaven, Germany. The objective of IBCSO was to create a first seamless Digital Bathymetric Model (DBM) covering the entire Southern Ocean. After the creation of the DBM two different maps have been produced based on the bathymetric model in collaboration with the Institute for Cartography of the TU Dresden. One version was designed to provide the scientific community with a new up to date ‘classic’ map of Antarctica. The second is envisaged to achieve largest possible outreach effect in the public by using the lenticular method. This method enables the beholder of the map to see the topography of the DBM in three dimensions without the necessity of auxiliary objects. The two different map versions of the IBCSO will be presented. The introduction includes a rough description of the working steps from ocean soundings to a combined digital bathymetric/topographic model. Furthermore, the steps to create the ‘classic’ and the lenticular map are described in detail.
