A unique database detailing the underwater terrain for waters around the UK has been made available.

A unique database detailing the underwater terrain for waters around the UK has been made available. SeaZone, a subsidiary of the UK Hydrographic Office, has spent 2 years capturing and processing hydrographic survey data for the project.

SeaZone’s Digital Survey Bathymetry extends across the majority of the UK continental shelf and represents the most detailed information of water depth available. It is much more accurate and detailed than depth soundings marked on traditional navigational charts.

Digital bathymetry data sources are either single-beam or multi-beam surveys, the majority of which were captured by the Royal Navy and the Civil Hydrography Programme. Other data is sourced from harbour authorities and private companies in the engineering, utilities, dredging, and the offshore oil and gas sectors.
