Marine data at the BGS

The RRS James Clark Ross in heavy seas

BGS manages marine data, information and material as part of the National Geoscience Data Centre (NGDC) and the Marine Environment Data and Information Network (MEDIN) geology data archive centre (DAC).

Geological, geophysical and environmental data on the seabed and sub-seabed are used to underpin the marine geoscience undertaken by the BGS and the wider user community in the UK and beyond. The data are used for a range of purposes, including the creation of BGS products.

Data are freely available online where possible under OpenGeoscience and the Open Government Licence. However, some data are not yet processed for online delivery and in these cases there may be a charge to cover data preparation. You can also deposit data with us.

Offshore GeoIndex samples Offshore GeoIndex

Use the Offshore GeoIndex to view and download data. Also available as a web map service (WMS).


The BGS is the MEDIN data archive centre (DAC) for geology. MEDIN, or the Marine Environment Data and Information Network, is a partnership of UK organisations committed to improving access to marine data. More information and summary of datasets held.

SEA logo SEA data portal

The Strategic Environmental Assessment (SEA) portal is run by the BGS on behalf of the Department for Business, Energy & Industrial Strategy (BEIS) and provides free access to data, information and reports produced through the SEA process.


The Marine Environmental Mapping Programme UK (MAREMAP) is a coordinated network of UK sea floor and shallow geological mapping. Maps are available to view via the Offshore GeoIndex.

EMODnet logo EMODnet geology

The BGS is part of the European Marine Observation and Data Network (EMODnet), working with partner geological surveys (Euro-Geosurveys) and others to improve access to marine data, products and metadata.


EGDI is the EuroGeoSurveys' European Geological Data Infrastructure. It provides access to pan-European and national geological datasets and services from the Geological Surveys of Europe.

Geo-Seas logo Geo-Seas

Geo-Seas was an EU FP7 project to expand the SeaDataNet infrastructure to marine geological and geophysical data.

NHDA logo National Hydrocarbons Data Archive

The National Hydrocarbons Data Archive (NHDA) is a long–term data archive of geoscientific legacy resulting from UK offshore oil and gas exploration and production activity. The NHDA was operated by the BGS under agreement with Department of Energy and Climate Change (now BEIS).

Vibrocore The BGS marine geoscience collection

This data is from geoscience surveys undertaken by BGS and other organisations collected using drilling, sampling and geophysical techniques. It includes digital data, paper records, and physical material.

Calm sea Deposit data

Deposit your marine geoscience data with us for long-term archival and online delivery.

DigSBS BGS marine products

A range of licensable products, including marine sediments 250k, marine bedrock 250k and magnetic and gravity compilations. Marine sediments and bedrock and other maps are also available to view via the Offshore GeoIndex or WMS.

Calm sea BGS marine geoscience

BGS Marine Geoscience has been undertaking an integrated program of research since 1966.

EMODnet ingestion portal EMODnet ingestion

The BGS is a partner in the EMODnet Ingestion project aiming to streamline the data ingestion process and connect marine data holders not yet connected to existing infrastructures. Deposit data via the EMODnet ingestion portal.

ECORD logo ECORD and IODP data

The BGS is the co-ordinator of the European Consortium for Ocean Research Drilling (ECORD) Science Operator (ESO) consortium that implements mission-specific platform (MSP) expeditions on behalf of the International Ocean Discovery Program (IODP). Access data from previous expeditions.

OneGeology logo OneGeology

OneGeology is an international initiative of the geological surveys of the world to 'make web-accessible the best available geological map data worldwide at a scale of about 1: 1 million'. The results can be seen on the OneGeology portal.
