GEBCO aims to provide the most authoritative, publicly available bathymetry data sets for the world’s oceans.
Gridded Bathymetry Data
GEBCO’s gridded bathymetric data sets are global terrain models for ocean and land, and includes the GEBCO 2014 Grid, a global 30 arc-second interval grid. The grids are available to download or access through Web Map Services.
Data & Products
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.
