The GEBCO_2024 global bathymetric grid

A new release of the global GEBCO bathymetric grid is now available to download.

The GEBCO grid is global data set of elevation values, in metres, on a 15 arc-second interval grid.

An additional 4.34 million square kilometres of bathymetric data has been added to the global grid since the last release  in 2023, with 26.1% of the seabed now mapped.

This is the Sixth GEBCO grid developed through the Nippon Foundation-GEBCO Seabed 2030 Project.This is a collaborative project between the Nippon Foundation of Japan and GEBCO. The aim of the project is to map the global sea floor by 2030.

GEBCO's grids can be downloaded as a global file in netCDF format or for user-defined areas, through our download app, in netCDF, data GeoTiff and ESRI ASCII raster formats. The data set can also be downloaded in the form of imagery.

This release of the GEBCO grid includes data from version 5.0 of the International Bathymetric Chart of the Arctic Ocean (IBCAO) .

Find out how to contribute bathymetric data sets to help update the global GEBCO grid.

GEBCO's aim is to provide the most authoritative publicly-available bathymetry of the world's oceans. It operates under the joint auspices of the International Hydrographic Organization (IHO) and the Intergovernmental Oceanographic Commission (IOC) (of UNESCO).
