The M2M Thematic Programme funded 17 scientific investigation projects leading to more unified physical understanding of fluid flow distributions in heterogeneous rock. The programme focused on developing an understanding of the relationships between measured and modelled subsurface fluid flows spanning the range of spatial and temporal scales relevant to fluid resource management. The programme was motivated by the growing recognition that assumptions of uniformity at certain scales are inadequate for extrapolating fluid behaviour both in time and space. Research spanning a wide spectrum of observation and simulation scales was undertaken by the programme which can be divided into four themes: (1) understanding the natural processes which lead to scaling relationships between size and magnitude of rock and flow heterogeneity; (2) quantification of essential fluid flow properties and their spatial pattern from measurements;(3) identification of appropriate statistical models and scaling laws describing rock property heterogeneity and fluid-rock interactions in geological media;(4) understanding the relationships between rock property distributions and flow model parameter distributions.
Paper records and photos used to create the Nottingham Caves digital register and maps. Includes archival material of the caves known to BGS, around northern and central Nottingham. Data mainly captured in 1989, infrequent since then approximately 1 per year.

The Britrocks database provides an index to the BGS mineralogical & petrological collection. The computer database covers samples in the UK onshore mapping collection together with world wide reference minerals and the Museum Reserve collection. Currently circa 200k out of circa 300k samples are recorded in the computer database. A collection audit is ongoing, so availability of any particular sample is not guaranteed. The first England and Wales collection sample is from circa 1877, Threshthwaite Comb, Cumbria (collected by the Reverend Clifton Ward). The addition of new samples, transfer of records from registers and updates of existing records is ongoing on a regular basis. Internet access to the database is provided on the BGS web site.
Annual means of the geomagnetic field vector components from observatories around the world, from 1840 to the present day. At present there are about 160 observatories. These data are useful for tracking changes in the magnetic field generated inside the Earth. Data are produced by a number of organisations around the world, including BGS. Data are available in plain text from www.geomag.bgs.ac.uk. This data is connected to other geomagnetic data sets, but can be used without reference to them.
The database contains a range of geochemical data for metamorphosed limestones from the Dalradian of Scotland and Northern Ireland. The data include a) whole-rock geochemical analyses by XRF (X-Ray Fluorescence) for major oxides and a range of trace elements for several hundred samples, b) a number of whole-carbonate O (oxygen) and C (carbon) stable isotope and Sr (strontium) data, c) electron microprobe mineral data on carbonates and calc-silicate minerals and d) ion-probe O stable isotope and mineral trace element data for calcites in a small number of samples. The samples from which the data have been derived were collected from a wide range of outcrops within the Scottish and Irish Dalradian, mainly concentrated in the North East Grampian Highlands of Scotland. The data have been collected mainly to support the mapping and scientific work being undertaken in the Grampian Highlands by BGS since the early 1980s. The database includes some data from the literature. All samples are located by British National Grid coordinates to the nearest 10m or better. The isotope data were acquired as part of a PhD study by C W Thomas in the late 1990s. The database is not currently being added to, but is still being used in various studies. The combined data provide wide-ranging insights into marine chemistry contemporary with deposition of the limestones and the way in which this chemistry changed with time during the Neoproterozoic, and they elucidate subsequent effects of diagenesis and metamorphism and the outcrop and grain-scale. The data set is largely complete with regard to geochemical data, but still requires some editing to bring all fields up to date, particularly with regard to lithostratigraphical assignation. The data are currently held in MS Access tables and can conveniently be displayed via GIS or abstracted in tabular form and used in spreadsheets, statistical analysis and graphing software.
Data on the physical properties (transmissivity, storage coefficient, porosity and permeability) of aquifers in England and Wales. Compiled by BGS staff from paper records of field and laboratory testing held by BGS, the Environment Agency and other organisations. Contains summary data on approximately 20,000 pump tests at over 2000 discrete locations. Raw data may be available on request. The majority of BGS and EA pump test data is included for both major and minor aquifers, but in minor aquifers this is complemented by data on specific yield. Laboratory determinations of porosity and permeability are limited to open file BGS data only. All data subject to similar processing and interpretation, but raw data highly variable.
The National Seismological Archive (NSA) is the United Kingdom national repository for seismological material. It was created principally to preserve data from seismological observatories in the UK that have now closed. In many cases in the past records have been lost or destroyed when there is no longer anyone to look after them; the NSA provides a permanent home for these historical scientific documents, to preserve them for posterity. The principal collection consists of the seismograms stores from defunct observatories; also bulletins and reports from all over the world dating from the 1890s onwards, held in a variety of media, including earthquake-related newspaper cuttings, glass slides, microfilm, and comprehensive UK earthquake research material collected over a 30 year period. The archive has a public access room available for researchers and welcomes visiting scientists who wish to study material held in it. If it is impractical to visit, we may be able to supply data from it, subject to staff availability. One of the major projects of the archive has been the presentation of current knowledge of UK historical earthquake seismology material in a short series of reports, easily accessible to researchers. These are available for download as Adobe Acrobat Portable Document Format files (.pdf) from the NSA download page.
This is a collection of extracts from British newspapers describing earthquakes, mostly British. It contains original clippings, photocopies, and in a few cases manual transcriptions.
The collection comprises plans of mine workings for ironstone, fireclay, limestone, baryte and metalliferous minerals for Scotland dating from 1872 onwards deposited on abandonment of a mine in compliance with the coal and metalliferous mines regulation acts. The plans are held on behalf of the Health & Safety Executive (HSE) and total about 610 plans. Indexed in the BGS Plans Database Index. As the collection relates to plans of mines abandoned after the 1872 Act, the holdings are fairly complete after this date. The Metalliferous Mines Act originally applied only to mines employing more than 12 men, (eg. some limestone mines). Where non-coal minerals were worked with coal, the abandonment plans are retained by the Coal Authority. Coal Authority also holds exclusively non-coal mine plans not covered by Mine Abandonment Plan collection. All non-confidential data held by NGRC Edinburgh (National Geological Records Centre). Mainly coalfield areas of Central Scotland with large collection relating to the Leadhills-Wanlockhead mining district.
