Imagery based on bathymetry data derived from the GEBCO_08 Grid shall not to be used for navigation or for any other purpose relating to safety at sea. The IHO, IOC, NERC and BODC are not able to warrant the accuracy of the data and accept no responsibility whatsoever for determining the fitness of the data for their intended use or for any consequential loss, damage or expense arising from such use. Users should be aware that most areas of the world's oceans have not been fully surveyed and that the GEBCO bathymetry is an interpretation based on random tracklines of data from many sources. The quality and coverage of data from these sources is highly variable. The GEBCO_08 Grid does not contain detailed bathymetry in shallow water areas.
