BGS MEDIN data archive centre

MEDIN logo

The Marine Environment Data and Information Network (MEDIN) is a partnership of UK organisations committed to improving access to marine data and easier data sharing. BGS is the accredited data archive centre (DAC) for geology, geophysics and backscatter.

If you would like to deposit data in the DAC, see our submission guidance.

MEDIN aims

The Sea
  • secure long-term management of marine datasets through a network of data archive centres (DACs)
  • improved access to marine data through a central discovery metadata portal
  • an agreed set of standards for metadata, data format and content
  • guidelines, contractual clauses and software tools to support standards and best practice data management

MEDIN data discovery portal

The MEDIN portal is a metadata discovery service providing users with a single point of access to a well-balanced, authoritative marine metadata catalogue.

Through initial discovery on the portal, users should be able to find out where the underlying data are available from. BGS-held data listed on the portal provide links to BGS's Offshore GeoIndex viewer service.

Data access

Offshore GeoIndex

The coverage of available data may be viewed and searched online via the Offshore GeoIndex. The Offshore GeoIndex is also available as a web map service (WMS) so that the layers can be added to desktop GIS.

Geological maps are displayed on the MAREMAP website.

A portal is also available for searching strategic environmental assessment (SEA) data (available for download depending on file size).

BGS is working towards providing access to more data online. However, the current method to request data is to contact the BGS's enquiries team ( with a list of the data required (sample and geophysical line numbers) or a specific enquiry.

Most data held by BGS are publicly available although some datasets may require approval from the data owner before they can be released. A handling fee may apply for data not available online to cover costs and additional work required. See the BGS policy on IPR.

MEDIN data archived in the DAC

Data archived at the BGS DAC include 18 Marine Aggregate Sustainability Levy Fund (MALSF) surveys 1.5 MB pdf, Joint Nature Conservation Committee (JNCC) surveys and seven Wessex Archaeology surveys.

BGS also collates information on oil and gas industry site surveys. Information on these data is available in the MEDIN data discovery portal though BGS doesn't hold these data.

Future archiving includes Marine Conservation Zone (MCZ) data.

How to archive data with the BGS MEDIN DAC

Data are submitted by prior mutual agreement between BGS and the submitting party.

The first stage is to provide a catalogue of the data being offered for archiving. BGS will then assess the contents of the catalogue and, if necessary, enter into discussion to clarify the information in it.

Depending on the volume, type, media and quality of the data, BGS may quote a cost for archiving the data. The agreement will include a schedule for delivery to BGS.
