Map the Gaps Symposium
Map the Gaps has convened a global event on bathymetry on behalf of GEBCO. Find out how to register and apply to present.
GEBCO’s gridded bathymetric data sets are global terrain models for ocean and land. The grids are available to download or access through Web Map Services.
GEBCO produces and makes available a range of bathymetric data sets and products. This includes a global bathymetric grid; gazetteer of undersea feature names, a Web Map Service and printable maps of ocean bathymetry.
Seabed 2030 is a collaborative project between the Nippon Foundation and GEBCO. It aims to bring together all available bathymetric data to produce the definitive map of the world ocean floor by 2030 and make it available to all.
The deepest depth measured so far in the oceans is around 10,920m in the Challenger Deep, part of the Mariana Trench, in the Northwest Pacific Ocean. For comparison, Mount Everest is around 8,850m high.
The GEBCO Gazetteer of Undersea Feature Names includes names for over 1,300 seamounts, (elevations on the seafloor over 1,000m high).
Since 2004, the Nippon Foundation/GEBCO Training Program has trained students from around the world in seafloor mapping through a one-year postgraduate course held at the University of New Hampshire, USA.
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).
