BGS have collected environmental radioactivity data for various purposes over several decades. This is being drawn together to produce a database of baseline gamma radioactivity and radon. Data includes the relevant portions of airborne and ground gamma spectrometer surveys, mineral exploration, baseline geochemistry and environmental radiometric surveys along with lithogeochemical and borehole log data. It is predominantly a specialist subset of other existing BGS databases. Incomplete UK coverage.
Stored in Murchison House, this dataset (FAUNGRAPHLOG_ED) is the BGS UK (North) collection of paper graphic logs from boreholes and measured natural sections, particularly in the Carboniferous of Scotland and northern England. Some 18000 of these records include hand written macrofossil occurrences and assemblages from certain (often subsequently interpreted) stratigraphical levels in the borehole or section. There is at present no separate index (either analogue or digital) to FAUNGRAPHLOG_ED but a pathway to it is FOSSLOC, the index to the Survey Collection of fossils from UK (North).
The database contains an index to over 600 ground geophysical surveys carried out in the UK for a variety of projects. A large number of these surveys were done for the DTI Mineral Reconnaissance Programme in the 1970s and 80s; many others were done at the request of BGS field mapping groups. Information held describes the survey objective, location of measurements, geophysical methods and equipment used, reports and publications, storage locations of data and results (for analogue and digital data), dates and personnel.
This digital data set contains original files of seismic reflection survey location (navigation) data and dates from the late 1970s. These provide location information for the Digital Seismic Sections data set (DIGSEISECS) and some of the printed seismic sections of the Original Seismic Sections dataset (ORIGSEISECS) and Copy Seismic Sections dataset (COPYSEISECS). Most data are within the UK Onshore area; although there are some UK near-shore and offshore (North Sea, Irish Sea) and foreign data. Most data were acquired for commercial hydrocarbon exploration and subsequently provided to BGS for use on specific projects. Some data were acquired by BGS (British Geological Survey) and other public-sector bodies, e.g. BIRPS (The British Institutions Reflection Profiling Syndicate), for academic research. The data are used with the Seismic Locations and Sections Database (LOCSEC) and for workstation-based interpretation. There are approximately 20 tapes and 15 Exabyte cartridges. The data are mostly concentrated in coal, oil and gas prospecting areas.
The data set consists of the results of particle size analysis (PSA) performed on approximetaly 29,000 sea-bed sediment samples collected by BGS from the UK Continental Shelf and adjacent deep water areas, mostly using sediment grabs, but also sediment corers on occasions. Measurements were also made on approximately 8000 downhole sub-samples from shallow cores and boreholes. Data from other UK organisations have also been added to the PSA dataset. The data are stored as part of the National Geoscience Data Centre (NGDC) and the Marine Environmental Data and Information Network (MEDIN) Data Archive Centre (DAC) for Geology and Geophysics. Data are delivered via the BGS Offshore GeoIndex www.bgs.ac.uk/GeoIndex/offshore.htm Seabed Sediment Data layers.
The purpose of this digital dataset is to provide accurate mapping of the distribution of sea-bed sediment types. Sea-bed sediments can only be mapped offshore, where the most recent deposits commonly form a veneer or superficial layer of unconsolidated material on the sea-bed. The dataset is produced for use at 1:250,000 scale. The boundaries between sediment classifications or types are delineated using sample station particle size analyses and descriptions, seafloor topography derived from shallow geophysical data and where available multibeam bathymetry and backscatter and side scan sonar profiles. The sediment types present on the sea-bed are of importance to a range of groups, including marine habitat mappers, marine spatial planners, the offshore construction and development sector, and the dredging and aggregate industries. These groups require detailed information on the nature of the sea-bed, including the sediment types present. The DiGSBS250k dataset has been created as vector polygons and are available in a range of GIS formats, including ArcGIS (.shp), ArcInfo Coverages and MapInfo (.tab). More specialised formats may be available but may incur additional processing costs.
These are scanned and georeferenced raster versions of the 1400 Ministry of Housing and Local Government (MHLG) Mineral Planning Permissions Maps (see associated metadata). The 1:25000 scale maps recorded hand drawn boundaries for permitted, withdrawn and refused mineral planning permissions and worked ground for every local authority area in England. Accompanying the maps is an associated card index (see metadata for MHLG Cards). The mineral planning permission polygons recorded on the maps have been digitised to create vector GIS polygons (see associated metadata for MHLG Planning Permission Polygons).
The SEA portal is managed by the BGS on behalf of DECC and provides free access to downloadable data, information and reports which have been produced through the SEA process. The Department of Trade and Industry (now DECC) began a sequence of sectoral SEAs of the implications of further licensing of the UK Continental Shelf (UKCS) for oil and gas exploration and production in 1999. The SEA Process subdivided the UKCS into eight areas shown; beginning in 2008, integrated Offshore Energy SEAs have been undertaken that cover the whole UKCS. An integral part of the SEA programme has been a series of research and monitoring surveys commissioned to acquire new data about the offshore environment and used to help inform the relevant SEAs. Many files can be downloaded directly from portal. Those that are too large to download can be ordered via the website for postal delivery from BGS.
This document data set contains original prints, on paper, sepia or film, of seismic reflection survey location (navigation) maps. These provide the location data for the seismic sections of the Original Seismic Sections (ORIGSEISECS) and Copy Seismic Sections (COPYSEISECS) datasets. Almost all data are within the UK onshore area; although there are some UK near-shore and offshore (North Sea, Irish Sea) and foreign data. Most data were acquired for commercial hydrocarbon exploration and subsequently provided to BGS for use on specific projects. Some data were acquired by BGS and other public-sector bodies, e.g. BIRPS, for academic research. All maps are digitised upon receipt (see LOCSEC database) and then archived in this data set. (Copies used to be used for interpretation purposes but this is no longer the case.) Documents stored rolled in tubes. Approx 800 maps.
Data identifying landscape areas (shown as polygons) attributed with geological names and rock type descriptions. The scale of the data is 1:50 000 scale. Onshore coverage is provided for all of England, Wales, Scotland and the Isle of Man. Superficial deposits are the youngest geological deposits formed during the most recent period of geological time, the Quaternary, which extends back about 2.58 million years from the present. They lie on top of older deposits or rocks referred to as bedrock. Superficial deposits were laid down by various natural processes such as action by ice, water, wind and weathering. As such, the deposits are denoted by their BGS Lexicon name, which classifies them on the basis of mode of origin (lithogenesis) with names such as, 'glacial deposits', 'river terrace deposits' or 'blown sand'; or on the basis of their composition such as 'peat'. Most of these superficial deposits are unconsolidated sediments such as gravel, sand, silt and clay. The digital data includes attribution to identify each deposit type (in varying levels of detail) as described in the BGS Rock Classification Scheme (volume 4). 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.
