Abstract

The International Bathymetric Chart of the Southern Ocean (IBCSO) version 1.0 is the first polar Digital Bathymetric Model (DBM) covering the entire Southern Ocean up to 60° S. It is going to be available to the public to serve as a base data set to several groups in Antarctic research, i.e. oceanographers, geophysicists and biologists. Just as its Arctic equivalent the International Bathymetric Chart of the Arctic Ocean (IBCAO) the IBCSO was initiated as a General Bathymetric Chart of the Oceans (GEBCO) regional mapping project. The project is endorsed by the Intergovernmental Oceanographic Commission (IOC) of UNESCO, the International Hydrographic Organization (IHO) and the Scientific Committee on Antarctic Research (SCAR). The IBCSO steering committee is an Expert Group of the Standing Scientific Group of Geosciences (SSG-GS) of SCAR and works in collaboration with the IHO Hydrographic Commission on Antarctica (HCA). Furthermore, an Editorial Board was established consisting of experts in Antarctic bathymetry from nations that acquire data in the Southern Ocean that collectively gathered bathymetric data from more than 30 institutions, in 15 different countries. The final version of the IBCSO version 1.0 DBM as well as its accompanied printable chart is going to be presented. This will include a description of specific techniques used to derive the DBM and an overview of the incorporated data sets. Furthermore, the result will be compared to other global bathymetric data compilations to show the improvement. In addition, the development of the printable chart and the chart itself is going to be described briefly.
