A new release of the GEBCO world map is now available, showing global bathymetry in the form of shaded relief for the world’s oceans.
The map, which is based on the 2022 release of the GEBCO grid and is supplied as very high-resolution downloadable files, has been released on the occasion of the 120th anniversary of the initiation of the GEBCO chart series.
Three versions are available: in standard projection centred on 90 degrees west or 150 degrees east, and a Spilhaus projection. The two main versions are suitable for printing at A0 size.
Also available are downloadable versions of the International Bathymetric Chart of the Arctic Ocean (IBCAO) and International Bathymetric Chart of the Southern Ocean (IBCSO) V2.
The IBCAO initiative aims to develop a digital database containing all available bathymetric data north of 64° north, while the aim of IBCSO is to gain better knowledge of the sea floor topography in the Southern Ocean by collecting and compiling bathymetric data from hydrographic offices, scientific institutions and data centres to produce the first regional digital bathymetric model that covers all circum-Antarctic waters.
