Welcome to the IBCSO website

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

The digital bathymetric model of IBCSO Version 1.0 has a 500 m x 500m resolution based on a Polar Stereographic projection with true scale at 65 S and covers the area south of 60 S. It is publicly available together with a digital chart for printing in via the Data tab.

We are encouraging holders of bathymetric data in the Southern Ocean to e-mail logo.png contact us if your data has not been contributed yet.
