The IHO-IOC GEBCO Cook Book

Background

GEBCO, the General Bathymetric Chart of the Oceans, is a joint project of the International Hydrographic Organization (IHO) and the Intergovernmental Oceanographic Commission (IOC) which brings together, under the guidance of the GEBCO Guiding Committee (GGC), an international group of experts whose aim is to provide the most authoritative publicly available bathymetry of the world's oceans, for scientific and educational use. GEBCO welcomes and encourages new contributions of data and expertise from all over the world.

One of GEBCO's products is a global gridded bathymetry data set. It is based on seafloor depths from ship soundings, and where there are no soundings, depths are interpolated using estimates from satellite altimetry as a guide. The global grid is periodically updated by incorporating additional bathymetric survey data, new compilations, and improved data.

The Cook Book is divided into three main sections "Gridding Examples-" written for beggining users desiring to straightaway produce a grid from xyz data, "Fundamentals-" which gives a more in-depth look at topics related to preparing, processing, and gridding xyz data, and "Advanced Topics-" which contains discussions more experienced users may find useful.

With this document, "The IHO-IOC GEBCO Cook Book," we hope to enable more people to contribute data and gridded compilations to GEBCO.
