Release of version 1.0 of the IBCSO
The aim of the International Bathymetric Chart of the Southern Ocean (IBSCO) programme is to gain a better understanding of the shape of the seafloor in the Southern Ocean area (south of 60°S).
To achieve this goal, the IBCSO group collects and compiles bathymetric data from hydrographic offices, scientific institutions and data centres to create a regional digital bathymetric model that covers all circum-Antarctic waters.
Version 1.0 of the IBCSO data is now available to download from the IBCSO web site.
The data set is made available in the form of digital grid and image files. It has been built from a database that currently consists of more than 4,200 million data points contributed by more than 30 institutions from 15 countries.
In order to build an authoritative global bathymetric model, the GEBCO Interim Sub-Committee on Regional Undersea Mapping (ISCRUM) aims to collaborate closely with regional expert groups, such as the IBCSO, to encourage the incorporation of their compilations into GEBCO.
It is planned to include the IBCSO data set in a future release of the GEBCO grid.
