High Resolution, Airborne Magnetic, Radiometric, VLF Survey over north Midlands of GB. Survey flying for the collaborative BGS and World Geoscience Corporation Ltd (WGC) high resolution geophysical and environmental survey was completed in early September 1998. The data comprise multi-channel gamma ray spectrometer, magnetometer and dual frequency VLF-EM. Flight line spacing was 400 m with tie lines at 1200 m and the total area surveyed is some 14 000 km2. Flight-line orientations are W–E over the western survey area, SW–NE over the eastern area. Ground clearance was maintained at 90 m in rural areas, increasing to about 240 m in built-up zones.

The BGS has been commissioned by Defra to provide guidance on what are 'normal' levels of contaminant concentrations in English soils in support of the revision of the Part 2A Contaminated Land Statutory Guidance. The domain polygons and other data produced by this work are served as WMS here.

This dataset represents a project-based collection of seismic interpretations of 2D and 3D commercial seismic reflection data. These data are integrated in a relational database in ORACLE in a data model called OpenWorks. Well log data, stratigraphic, velocity and well and seismic location data are also held in the database. Data interpretations are held within project indices by interpreter. Interpretations include faults and lithostratigraphic horizons. All data are commercial-in-confidence and cannot be supplied to any third party without the explicit permission of the customer or supplier.

The hydrogeological map indicates aquifer potential in generalised terms using a threefold division of geological formations: those in which intergranular flow in the saturated zone is dominant, those in which flow is controlled by fissures or discontinuities and less permeable formations including aquifers concealed at depth beneath covering layers. Highly productive aquifers are distinguished from those that are only of local importance or have no significant groundwater. Within each of these classes the strata are grouped together according to age or lithology. The 1:625 000 scale data may be used as a guide to the aquifers at a regional or national level, but should not be relied on for local information.

The TellusSW project acquired airborne geophysical data for the counties of Cornwall and parts of Devon and Somerset during the second half of 2013. The maps of the geophysical data and their derivatives are provided to facilitate spatial comparison with, and modelling of, the soil, geological and environmental aspects of the data. The survey comprised a high resolution magnetic/magnetic gradient survey combined with a multichannel (256 channel) radiometric survey. The survey was carried out using 200 m (N-S) line separations at a mean elevation of 91 m. The survey provided 60,323 line-km of data.

The joint PHE-BGS digital Indicative Atlas of Radon in Great Britain presents an overview of the results of detailed mapping of radon potential, defined as the estimated percentage of homes in an area above the radon Action Level. The Indicative Atlas of Radon in Great Britain presents a simplified version of the Radon Potential Dataset for Great Britain with each 1-km grid square being classed according to the highest radon potential found within it, so is indicative rather than definitive. The joint PHE-BGS digital Radon Potential Dataset for Great Britain provides the current definitive map of radon Affected Areas in Great Britain.

Data from the British Geological Survey's GeoIndex Geophysics theme are made available for viewing here. GeoIndex is a website that allows users to search for information about BGS data collections covering the UK and other areas world wide. Access is free, the interface is easy to use, and it has been developed to enable users to check coverage of different types of data and find out some background information about the data. More detailed information can be obtained by further enquiry via the web site: www.bgs.ac.uk/geoindex.

Miscellaneous geological records for Scotland and Northern England of current or semi-current interest filed in order of accession. Some 65 accessions held which will be subject to review for permanent retention/destruction. Dataset created c.1970 and Indexed on Land Survey Record Index Database.

The Land Survey Archives consists of records of the Geological Survey in Scotland for permanent retention dating from 1860s onwards. The collection comprises geologists' field notebooks, miscellaneous field observations and reports, historical and biographical material, correspondence files, photographs, etc. Includes archival material deposited by outside individuals and organisations, eg. NCB (National Coal Board) Bore Book Collection. Survey archival material for Northern England will be incorporated. Some 380 accessions held amounting to over 7,000 items. Indexed at collection level in Land Survey Record Index (LSRI). Plans abstracted and held separately in Land Survey Plans Collection.
