GEBCO Grid Global terrain model for oceans and land at 30 arc-second intervals produced by General Bathymetric Chart of the Oceans (GEBCO)
The GEBCO Grid is a global terrain model for oceans and land at 30 arc-second intervals which was developed and first released in 2009 by the General Bathymetric Chart of the Oceans (GEBCO) as GEBCO 08. The current release is GEBCO 2014, released in December 2014 and updated in March 2015. GEBCO is an international group of experts who work on the development of a range of bathymetric (accurate mapping of the sea floor) data sets and data products. The bathymetric portion of the grid is largely based on a database of ship-track soundings with interpolation between soundings guided by satellite-derived gravity data. Data sets developed by other methods are also included where they improve the grid. The land portion of the grid is largely based on the US Geological Survey's SRMT30 data set, developed with data from the US National Aeronautics and Space Administration (NASA) Shuttle Radar Topographic Mission (SRTM). For the area around Antarctica, the land data are taken from the Bedmap2 data set. The grid is accompanied by a Source Identifier (SID) Grid which identifies which cells in the GEBCO Grid are based on soundings or existing grids and which have been interpolated. The data sets are updated as new bathymetric compilations are made available. Both grids are freely available to download, in netCDF; data GeoTiff and Esri ASCII raster formats, from the web. Free software is available for viewing and accessing data from the grids in netCDF and ASCII data formats. The grids are also included as part of the GEBCO Digital Atlas DVD.

BODC protocols are based on the Open Archival Information System (OAIS) model enabling BODC to iterate towards compliance with the on-going evolution and development of community requirements including FAIR (Findable,Accessible,Interoperable,Reusable), TRUST (Transparency, Responsibility, User community, Sustainability, Technology) and CARE (Collective Benefit, Authority to Control, Responsibility, Ethics). Data managers quality assure submissions and assemble the metadata necessary for curation. Submissions (as received) are placed in a long-term accession and stored in triplicate across multiple sites. Appropriate data are transferred into a standard internal format with source variable names mapped to controlled vocabularies, documentation assembled, and metadata loaded into BODC databases. Access to these data is through direct request, the BODC website and through partner repositories such as SeaDataNet. Access control is attained by assigning a data policy to each set of data and this policy is used to administer access when data are requested. Discovery metadata is aligned with EU INSPIRE (through MEDIN) and SeaDataNet community standards. Data are converted to open community formats including Ocean Data View ASCII and SeaDataNet NetCDF, with data described using terms from the NERC vocabulary server. BODC submission agreements are documented on the BODC website and customer service is assured with a dedicated requests team that serve data following local regulations including General Data Protection Regulation (GDPR) 2018 and Environmental Information Regulations (EIR) 2004.

The GEBCO_08 Grid has been developed by the General Bathymetric Chart of the Oceans (GEBCO) community. The bathymetric portion of the grid has largely been generated from a database of ship-track soundings with interpolation between soundings guided by satellite-derived gravity data. However, in areas where they improve on the existing GEBCO_08 grid, data sets generated by other methods have been included. The grid is maintained and made available by BODC on behalf of GEBCO. Further details about the development of the grid and its update history can be found in the data set documentation: http://www.gebco.net/data_and_products/gridded_bathymetry_data/documents/gebco_08.pdf
