The collection includes colour microfilm aperture card copies of 7,170 plans of mine workings for coal and oil shale dating from 1872 onwards deposited on abandonment of a mine in compliance with the Coal Mines Regulation Act. An additional c.5,000 coal 'working' plans, mostly pre-dating 1872, formerly belonging to British Coal, have been added to the abandonment plan collection. The latter are held as black & white microfilm aperture cards. The collection includes plans of workings for other minerals, notably ironstone, where worked with coal. The microfilms are held on behalf of the Coal Authority who hold the original plans on behalf of the Health & Safety Executive (HSE). Original plans are held by the Coal Authority, Mansfield. No complete digital index held by BGS. An up to date finding aid is provided by the Coal Authority's paper 'Catalogue of Plans of Abandoned Mines'. The collection is believed to be fairly complete for mines abandoned since the 1872 Act. Plans were added from the British Coal plan collections to fill gaps in holdings, particularly for mines abandoned prior to 1872. Relates to coalfield areas of Central Scotland.

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.

This dataset includes stream and rainfall hydrochemistry of the Plynlimon research catchments in Mid Wales. The data cover the period from March 2016 to March 2019. Sampling was carried out fortnightly from March 2016 to July 2017. From August 2017 to November 2018 stream samples were collected every four weeks and the rain sample every two weeks. From December 2018 onwards all samples were collected every four weeks. Data are presented for major anions and cations, pH, conductivity, alkalinity, in-situ measurements of water temperature and stream flow for the six stream locations, and air temperature and volume for the rainfall sites. Stream samples were taken using a grab technique and filtered in the field. Rain samples were collected using bulk precipitation collectors. Fieldwork was carried out by CEH members of staff trained in the fieldwork techniques required. Chemical analysis was carried out by qualified CEH chemists at laboratories at CEH Lancaster and CEH Bangor. The Plynlimon research catchments lie within the headwaters of the River Severn and the River Wye in the uplands of mid-Wales. Intensive and long-term monitoring within the catchments underpins a wealth of hydrological and hydro-chemical research. Monitoring is funded by the Centre for Ecology & Hydrology, and is ongoing since 1968. Full details about this dataset can be found at https://doi.org/10.5285/54fe47f3-778e-4e0b-8cf5-b2fda2473b7f

This dataset contains daily automated weather station (AWS) data from the Climoor field site in Clocaenog forest, North East Wales. The data are air temperature (mean, minimum and maximum), rainfall, net radiation, solar radiation, photosynthetically active radiation (PAR), wind speed and direction. The dataset has been quality checked, and incorrect or missing values removed, data has not been infilled. Data runs from 12/6/1999 until 30/06/2015, no data was collected March 2006 and June 2008. Air temperature, rainfall and wind speed and direction were recorded since June 1999. Measurements of relative humidity, air pressure, net and solar radiation and PAR started in June 2008. Since June 2008, data are recorded in minute intervals, averaged to hourly, then to daily means that are reported here. The Climoor field experiment intends to answer questions regarding the effects of warming and drought on ecosystem processes. The reported data are collected to monitor site specific environmental conditions and their development with time. These data are important to interpret results that are collected from the climate change manipulations imposed in the field.

This dataset includes rainfall, cloud and stream hydrochemistry of the Plynlimon research catchments in Mid Wales. The data cover the period from June 2011 to March 2016. Sampling was weekly from June 2011 to December 2011 and then fortnightly from January 2012. Data for the whole period are presented for major anions and cations, pH, conductivity, alkalinity and in-situ measurements such as water temperature and stream flow. From June 2011 to March 2013 data are also presented for a range of metals. Data are presented for the whole period for six stream locations and one rainfall site. Data are also for presented for two streams, Nant Iago and Tanllwyth and one cloud site for the period from June 2011 to July 2012. Stream samples were taken using a grab technique. Rain samples were collected using bulk precipitation collectors. Cloud samples were collected using a Centre of Ecology and Hydrology (CEH) Edinburgh pattern lidded harp type passive collector. This data presented follow on from the hydrochemical data presented in the dataset Plynlimon research catchment hydrochemistry (44095e17-43b0-45d4-a781-aab4f72da025) Fieldwork was carried out by CEH members of staff trained in the fieldwork techniques required.

This service displays a series of datasets consisting of mean estimate distribution maps of ash trees (Fraxinus excelsior) across Great Britain. It includes ash trees in areas less than half a hectare, ash trees in woody linear features and individual ash trees. The data are derived from Countryside Survey 2007. Trees were mapped in 569 1km sample squares across Britain using a stratified random sampling system based on the ITE Land Classification. Mean national estimates were produced by scaling up from the sample data.

Mean daily flow and water chemistry data collected from the Tarland Burn, recorded between 2000-2010. Water chemistry determinands measured include: total dissolved phosphorus (TDP), soluble reactive phosphorus (SRP), total phosphorous (TP), particulate phosphorus (PP), nitrate (NO3-N), ammonium (NH4-N) and suspended sediments (SS); water chemistry measurements are in units of mg l-1 for all determinands. Sampling for water chemistry took place at a weekly frequency between 2000 and the end of 2003, with some daily sampling during rainfall events. Daily samples were then collected between February 2004 and June 2005. After June 2005, infrequent irregular sampling took place, with fewer determinands. Mean daily flow, in m3s-1, was also recorded. The Tarland Burn is a tributary of the River Dee (northeast Scotland). The samples were collected at Coull (WGS84 57.111, -2.810; OSGB 351050, 802540).

This database stores down-hole stratigraphic data to complement the seismic surface picks stored in the Seismic Locations And Sections Database (LOCSEC). Because these surfaces are chosen for their visibility on seismic data, they may not be directly equivalent to established BGS lithostratigraphic and/or choronstratigraphic divisions. However, the local coding system is based on and can relate to the BGS stratigraphic LEXICON. Stratigraphic picks are stored in terms of depth and seismic one-way travel time. Local borehole summary information (location, elevation, etc.) is used because both onshore and offshore boreholes are stored in this database. These data can be related to the BGS onshore borehole database by borehole registration, and to the offshore well database by DTI well-id. Additional tables (under development) provide information on hydrocarbon tests and their results. Almost all data are within the UK Onshore area; although there are some UK near-shore and offshore (North Sea, Irish Sea).

Rocks, thin sections and paper registers: samples from past BGS surveys and projects overseas. Though neglected for several years, the collection has been re-opened for addition of new material from overseas projects and donations. Paper registers are arranged by accession order on a country by country basis. The records have not been placed in electronic format and are not currently machine readable.

Records of some 3500 waste sites in England and Wales identified by BGS as part of a survey carried out on behalf of the Department of the Environment in 1973. Information is included on the extent of the site, geology, wastes and risks to aquifers It should be noted that the assessments were carried out when the data was collected and may not reflect current interpretation. There are not records for all of the sites listed.
