International Bathymetric Chart of the Southern Ocean (IBCSO)

The objective of the IBCSO program is to gain better knowledge of the sea floor topography in the Southern Ocean. To achieve this, the IBCSO group collects and compiles bathymetric data from hydrographic offices, scientific institutions and data centres to create the first regional digital bathymetric model that covers all circum-Antarctic waters.
