International Bathymetric Chart of the Southern Ocean (IBCSO)

The International Bathymetric Chart of the Southern Ocean aims to design and implement an enhanced digital database that contains bathymetric data available south of 50°S latitude, leading to the production of a consistent bathymetric chart of the Southern Ocean.

In 2017, the International Bathymetric Chart of the Southern Ocean (IBCSO) became part of the Nippon Foundation – GEBCO Seabed 2030 project and is chaired by the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) in Bremerhaven, Germany, as the Southern Ocean Regional Center.

The IBCSO version 1.0 grid was made available to the public in 2013, available south of 60°S with a 500m x 500m resolution in a Polar Stereographic projection, and was incorporated into the General Bathymetric Chart of the Ocean (GEBCO). The IBCSO version 2.0 grid is enlarged to south of 50°S and is currently underway with its expected release soon.
