A number of datasets are available either in digital or analogue versions.
BGS offshore geochemical data, consisting of a set of 38 elements, are available from seabed samples collected from a variety of sediment types occurring in a wide range of environments. Samples have been collected offshore off the eastern shores of the UK, where heavily populated and industrialised catchment areas are drained by major rivers such as the Thames, Humber and Tyne, flowing into the North Sea. In contrast, samples are also available from the continental shelf west of Scotland, where man's activities have had considerably less impact. The data provide a baseline for chemical element concentrations in seabed sediments, against which samples collected in the future may be assessed. It should therefore be of significance to a diverse range of interests including pollution control, fishing, natural resources, nature conservation, shipping, tourism, recreation, and waste disposal management. In addition, the information derived from the data will be of use to geologists in identifying the source of seabed sediments and any underlying deposits.
The surveys include:
Unadjusted ship gravity, magnetic and bathymetry data acquired by BGS as part of its Offshore Reconnaisance Mapping Programme. This programme commenced in 1967, and was funded mainly by the Department of Energy. Unadjusted ship gravity and bathymetry data from various commercial and academic surveys between 1965 and 1994. Confidential MOD Hydrographic Office integrated ship gravity and magnetics surveys of North West Europe marine areas for which BGS acts as agent. Network adjusted gravity and magnetic compilations of data from BGS and non-BGS sources.

MEDIN is a partnership of UK organisations committed to improving access to marine data. It is an open partnership and its partners represent government departments, research institutions and private companies. MEDIN sits alongside its sibling working group the Underwater Sound Forum (USF). Both groups report directly to the Marine Science Coordination Committee (MSCC).
More information is available at the MEDIN website.
MEDIN promotes sharing of, and improved access to, marine data and aims to provide:
The MEDIN portal is a metadata discovery service providing users with a single point of access to a well-balanced, authoritative marine metadata catalogue. Search the MEDIN Data Archive Centres.
BGS operates as the Data Archive Centre (DAC) for seabed and sub-seabed geology and geophysics, provides input to the above portal and further information via the BGS website and the Offshore GeoIndex.
The BGS Marine Survey Data Management Handbook describes the management of BGS marine survey data.
BGS has created a Survey Folder Structure 150 KB pdf for geological and geophysical survey data which can be used offshore and for submitting data to BGS. This folder structure may be adopted by external organisations and can be used for submission of data to the BGS MEDIN DAC.
BGS MEDIN DAC: Oil and gas industry site surveys
As part of the BGS MEDIN DAC, we hold information about oil and gas industry site surveys. The Offshore GeoIndex layer shows the geographic location of the underlying data together with the contact details of the data holders. For further information contact the custodian of the data.
More details at the MEDIN Oil and Gas Industry Site Survey Project.
BGS are showing selected DECC offshore data so they can be viewed in context against data and information available from BGS. The source data is from the DECC Offshore maps and GIS shapefiles. These are DECC owned data.
The primary location for comprehensive UK Oil and Gas Industry information and data access is the UK DEAL website.
The DECC website also makes available a range of offshore data and information. For more details, see DECC Data & maps.
The Strategic Environmental Assessment (SEA) data portal is managed by BGS on behalf of DECC and contains free access to available information and reports which have been produced through the SEA process. Many files can be downloaded directly and those that are too large to download can be ordered via the website.
DEAL is the gateway to information on the UK Offshore Oil & Gas Industry and provides quick and easy access to catalogues of data available from release agents, geophysical companies and licence operators alike. DEAL is:
Registration allows users to carry out both map and form based searches on catalogues of released well and seismic data, subscription provides access to advanced facilities.
Agreed boundaries between international offshore designated areas.
A quadrant is a means of dividing offshore areas in to identifiable parts. Blocks are a subdivision of a quadrant.
