  • Magnetograms are used to record variations in the Earth's magnetic field. Original paper magnetograms were recorded using photographic technqiues at Kew, Greenwich, Abinger, Hartland, Eskdalemuir and Lerwick Observatories. These magnetograms start in the 1840s and end in 1986 at which time digital recording of the magnetic field took over and magnetograms can be produced by computer graphic. The plots show variation in the Earth's magnetic field, typically over a 24-hour period.

  • Registers of macrofossils in 127 volumes, covers the whole of the UK. Within each volume, data is arranged sequentially usually by collectors no. The data set began with the first Palaeontologist in the Geological Survey of Great Britain.

  • The dataset is based on a 1 hectare(ha) vector grid which covers the whole of England. It has been populated with a series of environmental and cultural assets, reflecting the presence or absence of an asset in an individual cell. The dataset has been designed to enable a single asset to be displayed in a generalised fomat; total numbers of assets within a given cell; or the opportunity to create in unique combination of the assets based on the generalised 1 ha data. The data is also available at 1km.

  • The WellMaster database holds hydrogeological information on water wells for wells and boreholes identified within the Single Onshore Borehole Index (SOBI) within England Wales and Scotland. The database contains index details supplementary to SOBI, including information on the availability of more detailed hydrogeological information. Four main categories of data are held within the database; lithostratigraphic details, well/borehole construction including casing and screens, water information including depths and pumping rates and water quality information.

  • 'Archive' collection of c.3,000 records of the former Industrial Minerals Assessment Unit (IMAU) relating to sand and gravel assessment projects in Scotland, 1978-88. Includes borehole and trial pit records, grading and resource assessment data and aggregate tests.

  • Photographic negatives of Geological map 'Standards', manuscript and published maps produced by the Survey on County Series (1:10560) and National Grid (1:10560 & 1:10000) Ordnance Survey base maps. Current holdings over 41,000 maps for Great Britain. The majority of maps were scanned in 2004, any new maps produced are scanned and added to the collection. This is essentially a back up collection for disaster recovery.

  • Index to the BGS collection of large scale or large format plans of all types including those relating to mining activity, including abandonment plans and site investigations. The Plans Database Index was set up c.1983 as a digital index to the collections of Land Survey Plans and Plans of Abandoned Mines. There are entries for all registered plans but not all the index fields are complete, as this depends on the nature of the original plan. The index covers the whole of Great Britain.

  • 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.

  • 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.

  • EPSRC grant EP/L012227/1: Development of Unified Experimental and Theoretical Approach to Predict Reactive Transport in Subsurface Porous Media. The effect of pore-scale heterogeneity on non-Darcy flow behaviour is investigated by means of direct flow simulations on 3-D images of Estaillades carbonate. The critical Reynolds number indicating the cessation of the creeping Darcy flow regime in Estaillades carbonate is two orders of magnitude smaller than in Bentheimer sandstone, and is three orders of magnitude smaller than in the beadpack. It is inferred from the examination of flow field features that the emergence of steady eddies in pore space of Estaillades at elevated fluid velocities accounts for the early transition away from the Darcy flow regime.
