Bathymetry of the Pacific Ocean from the GEBCO One Minute GridGEBCO overview

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 Intergovernmental Oceanographic Commission (IOC) (of UNESCO) and the International Hydrographic Organization (IHO).

Organisational structure

We are a non-profit making organisation which relies largely on the voluntary contributions of an enthusiastic international team of geoscientists and hydrographers. GEBCO's work is directed by a Guiding Committee and supported by sub-committees on ocean mapping and undersea feature names plus ad hoc working groups.

These committees meet on a regular basis. Find out more about the people involved in GEBCO and upcoming and previous meetings.

GEBCO has its origins at the beginning of the 20th century. Find out more about GEBCO's history from the initiation of the chart series in 1903 to the present day.

Outputs from our work

We produce a range of bathymetric data sets and products. This includes global gridded bathymetric data sets a global set of digital bathymetric contours; the GEBCO Gazetteer of Undersea Feature Names; the GEBCO Digital Atlas; the GEBCO world map and the IHO-IOC GEBCO Cook Book— a reference manual on how to build bathymetric grids.

Contributing data

GEBCO is continually working to improve its gridded data sets with the aim of providing the most authoritative publicly-available bathymetric grids for the world’s oceans.

We are grateful for contributions of single-beam and/or multibeam survey data, individual soundings or existing grids to help update our gridded data sets and products. We acknowledge the source of contributed data in the documentation which accompanies GEBCO's data sets.

Find out how to contribute data to help update GEBCO's grids.

Training a new generation of scientists

The Nippon Foundation of Japan has provided funding for GEBCO to train a new generation of scientists and hydrographers in ocean bathymetry. The 12-month course, leading to a Postgraduate Certificate in Ocean Bathymetry (PCOB), has been held at the University of New Hampshire, USA since 2004.
