IBCSO V1.0 Digital Bathymetric Model
The IBCSO version 1.0 digital bathymetric model is available in three different cartographic projections, each in the formats NetCDF (GMT), SD (Fledermaus), and GeoTIFF (ArcGIS).
Besides the standard model version with bedrock elevation for continental Antarctica a version with ice surface elevation is available.
When using the datasets please refer to Reference. The digital bathymetric model can be obtained here:
IBCSO Printable Chart
The IBCSO digital printable chart has been designed based on the IBCSO version 1.0 digital bathymetric model. It has a scale of 1 : 7 000 000 is 1 m x 1.2 m large and is based on a polar stereographic projection with true scale at 65° S. The design of the map was supported by two students of the Cartographic Institute of TU Dresden. A raw preview of the IBCSO digital chart can be seen below.
The digital version is available for download at PANGAEA. The printed version can be ordered via the NGDC.
When using the chart please refer to Reference.

The IBCSO database currently consists of more than 4200 million data points contributed by more than 30 institutions from 15 countries. In total 177 Multibeam
cruises were available building the nuclei of the database. Single beam echo sounding data, digitized soundings from nautical charts and regional bathymetric
compilations are rounding off the database. A list of datasets used for the compilation of IBCSO Version 1.0 can be downloaded here:
An overview of included data sources and the spatial distribution can be seen in the source identification map below.
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:
If you are holding bathymetric data that is not yet included in the IBCSO database, we encourage you to contribute this data to improve the IBCSO digital bathymetric model for the benefit of all. Contributed data will be acknowledged and will only be used to generate the IBCSO digital bathymetric model. To contribute data please contact us .
To enable users to visualize their own data on a map with the IBCSO look and feel, we are offering the base data of the IBCSO printable chart as a georeferenced image.
The 'Background' maps contain RGB rasterfiles in GeoTiff format, which is compatible with most GIS programs. In addition, we offer the contours of the IBCSO Version 1.0 bed elevation digital bathymetric model in 500 m intervals as Shape files.
