Radon is a natural radioactive gas, which enters buildings from the ground. The joint Public Health England (PHE) –British Geological Survey (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. Exposure to high concentrations increases the risk of lung cancer. PHE (formerly the Health Protection Agency (HPA)) recommends that radon levels should be reduced in homes where the annual average is at or above 200 becquerels per cubic metre (200 Bq m-3). This is termed the Action Level. Public Health England defines radon Affected Areas as those with 1% chance or more of a house having a radon concentration at or above the Action Level of 200 Bq m-3. The Indicative Atlas of radon in Great Britain presents a simplified version of the radon potential 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 for Great Britain provides the current definitive map of radon Affected Areas in Great Britain. The Indicative Atlas of radon in Great Britain is published in two documents. The area of England and Wales is published in MILES J.C.H, APPLETON J.D, REES D.M, GREEN B.M.R, ADLAM K.A.M and MYERS, A.H., 2007. Indicative Atlas of Radon in England and Wales. ISBN: 978-0-85951-608-2. 29 pp). The corresponding publication for Scotland is MILES J.C.H, APPLETON J.D, REES D.M, ADLAM K.A.M, GREEN B.M.R, and SCHEIB, C., 2011. Indicative Atlas of Radon in Scotland.).

The dataset describes the relative vulnerability of groundwater to contamination across Scotland, by means of five relative classes ranging from 1 (lowest vulnerability) to 5 (highest vulnerability). The dataset is a screening tool that can be used to show the relative threat to groundwater quality from contamination across Scotland. It can provide guidance on the vulnerability of groundwater at a regional scale, highlighting areas at comparatively higher risk of groundwater contamination, and can help indicate the degree of specific site investigation required for a new development or activity. It is designed to be used at a scale of 1:100,000 and should be regarded as a tool to aid groundwater risk assessment rather than a complete solution. Latest version: Groundwater Vulnerability Scotland version 2

Data identifying landscape areas (shown as polygons) attributed with geological names and rock type descriptions. The scale of the data is 1:10 000 scale providing bedrock geology. Onshore coverage is partial with approximately 30% of England, Scotland and Wales available in this version 2 data release. BGS intend to continue developing coverage at this scale; current focus is to include all large priority urban areas, along with road and rail transport corridors. Bedrock geology describes the main mass of solid rocks forming the earth's crust. Bedrock is present everywhere, whether exposed at surface in outcrops or concealed beneath superficial deposits or water bodies. The bedrock geology of Great Britain is very diverse and includes three broad classes based on their mode of origin: igneous, metamorphic and sedimentary. The data includes attribution to identify each rock type (in varying levels of detail) as described in the BGS Rock Classification Scheme (volumes 1-3). The bedrock has formed over long periods of geological time, from the Archean eon some 7500 million years ago, to the relatively young Pliocene, 58 million years ago. The age of the rocks is identified in the data through their BGS lexicon name (published for each deposit at the time of the original survey or subsequent digital data creation). For stratified rocks i.e. arranged in sequence, this will usually be of a lithostratigraphic type. Other rock types for example intrusive igneous bodies will be of a lithodemic type. More information on the formal naming of UK rocks is available in the BGS Lexicon of Named Rock Units. Geological names are based on the lithostratigraphic or lithodemic hierarchy. The lithostratigraphic scheme arranges rock bodies into units based on rock-type and geological time of formation. Where rock-types do not fit into the lithostratigraphic scheme, for example intrusive, deformed rocks subjected to heat and pressure resulting in new or changed rock types; then their classification is based on their rock-type or lithological composition. This assesses visible features such as texture, structure, mineralogy. The data are available in vector format (containing the geometry of each feature linked to a database record describing their attributes) as ESRI shapefiles and are available under BGS data licence.

LCM2007 is a parcel-based thematic classification of satellite image data covering the entire United Kingdom. The map updates and upgrades the Land Cover Map of Great Britain (LCMGB) 1990 and LCM2000. Like the earlier 1990 and 2000 products, LCM2007 is derived from a computer classification of satellite scenes obtained mainly from Landsat, IRS and SPOT sensors. It also covers Northern Ireland and incorporates information derived from other ancillary datasets. LCM2007 was classified using a nomenclature corresponding to the Joint Nature Conservation Committee (JNCC) Broad Habitats, which encompasses the entire range of UK habitats. In addition, it recorded further detail where possible, incorporating land cover classes sought by other users. LCM2007 is produced in both vector and raster formats, with a number of different versions containing varying levels of detail and at different spatial resolutions. This dataset consists of the 1km raster, percentage Aggregate Class. Northern Ireland only.

The dataset contains detrital zircon U-Pb ages from a large scale detrital provenance study of modern and recent sand and silt from the Chinese Loess Plateau (CLP) and its proposed sources in the Yellow River, its Tibetan headwaters, and the Taklamakan Desert, which lies upwind from the CLP.

The BGS 3D scans store holds digital 3-dimensional scans of BGS palaeontological and petrological specimens. The data include 3-dimensional meshes and 2-dimensional images exported by the scanning hardware and software. Data are stored in software-independent 3D modelling formats such as .OBJ and .PLY. These scans are useful for research purposes, for example allowing members of the broader geoscience community to interactively view a particular specimen, and for publicising BGS specimen holdings.

Data from the British Geological Survey's GeoIndex Map products 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.

This dataset contains data from a marine multibeam and geophysical survey which took place in June 2011 in the Ardmucknish Bay area on board the BGS survey vessel RV White Ribbon. The survey was carried out by the British Geological Survey (BGS) in collaboration with Scottish Association for Marine Science (SAMS) and National Oceanography Centre (SAMS). QICS (Quantifying and monitoring potential ecosystem impacts of geological carbon storage) was a scientific research project funded by NERC. The purpose was to collect the data necessary to identify a potential directional drilling route from shore to a submerged gas release point. Sea floor bathymetry data were collected using an EM3002D. Sub bottom seismic profiling data were collected using a surface tow boomer. Technical details of the survey are contained in the BGS Report of Survey. Webpage www.bgs.ac.uk/QICS/. NERC Grant. NE/H013962/1.

Note: This dataset is designed for the 1:50000 scale but can be viewed in this WMS between 1:100000 and 1:25000 (Only). The 1:50 000 DiGMapGB data covering the whole of the United Kingdom is available in this OGC WMS service for your personal, non-commercial use only. Separate bedrock geology, superficial deposits, artificial ground, mass movement deposits and geological linear features layers are available in this service.
