  • This dataset consists of invertebrate species records, sampled from headwater streams during a survey in 1998. Macro-invertebrates were sampled using standard protocols. The sample area in each stream was a single area of stream-bed whose major habitat types can be sampled within the recommended sampling period of three minutes of active sampling, supplemented by a one minute hand search. The length of river surveyed would normally vary from 5 to 15m. Samples were collected using a standard 1mm mesh pond net and returned to the Centre for Ecology & Hydrology (formerly Institute of Freshwater Ecology) for later sorting and identification. Supplemental physical measurements (width, depth, substrate composition) required to run RIVPACS (River Invertebrate Prediction and Classification System) were taken. Data were collected under the Countryside Survey long term monitoring project managed by the Centre for Ecology & Hydrology. The Countryside Survey is a unique study or 'audit' of the natural resources of the UK's countryside. The sample sites are chosen from a stratified random sample, based on a 15 by 15 km grid of GB. Headwater stream surveys have been carried out in 1990, 1998 and 2007 with repeated visits to the majority of sites. The countryside is sampled and surveyed using rigorous scientific methods, allowing us to compare new results with those from previous surveys. In this way we can detect the gradual and subtle changes that occur in the UK's countryside over time. In addition to headwater stream data, soil data, habitat areas, vegetation species data and linear habitat data are also gathered by Countryside Survey.

  • This dataset consists of macrophyte species records, sampled from headwater streams during a survey in 1998. Stream macrophytes in Countryside Survey are surveyed using the standard MTR (Mean Trophic Rank) protocol, which records the presence and extent (on a categorical scale) of macrophytes in a 100m reach. Data were collected under the Countryside Survey long term monitoring project managed by the Centre for Ecology & Hydrology.

  • River Habitat Survey (RHS) data from rivers and streams surveyed in 1998 as part of the Countryside Survey project. River Habitat Survey (RHS) is an assessment of the physical structure of freshwater streams and rivers based on a standard 500m length sample unit. It does not require specialist geomorphological or botanical expertise but consistent recognition of features included on the form is essential. To ensure consistency of recording all surveyors must be accredited, and recording follows standard protocols. Data were collected under the Countryside Survey long term monitoring project managed by the Centre for Ecology & Hydrology.

  • This dataset consists of results of chemical analyses of single water chemistry samples, taken from headwater streams during a survey in 1998. Water samples were analysed at the Centre for Ecology & Hydrology for chemical analysis of alkalinity (at pH 8.3) and soluble reactive phosphorus. Conductivity and pH were measured in the field using a regularly calibrated field meter. Data were collected under the Countryside Survey long term monitoring project managed by the Centre for Ecology & Hydrology.

  • The SACS Best Practice Manual consists of two parts. The first part outlines the operational experiences gained during the Sleipner CO2 injection operation. The second part consists of recommendations based on the monitoring the Sleipner CO2 injection operation during the SACS project. The report can be downloaded from http://www.ieaghg.org/docs/General_Docs/Reports/SACS%20Best%20Practise%20Manual.pdf.

  • Several coal resource maps for the whole of the UK have been produced by the British Geological Survey as a result of joint work with Department of Trade and Industry and the Coal Authority. The UK Coal Resource for new exploitation technologies map is a map of Britain depicting the spatial extent of the principal coal resources overlayed with existing workings and potential new technologies for accessing the resource. The map also shows the areas where coal and lignite are present at the surface and also where coal is buried at depth beneath younger rocks. The project covers all onshore coalfields in the UK, including Northern Ireland. It includes coal under estuaries and near-shore areas that can practically be reached by land-based directional drilling. No data more than 5 km offshore were considered. The maps are intended to be used for resource development, energy policy, strategic planning, land-use planning, the indication of hazard in mined areas, environment assessment and as a teaching aid. In addition to a summary map at 1:750000 scale for Britain data also exists for each technology of 21 individual regions or coal fields at a scale of 1:100000. The data was published in printed map form for the summary map, inkjet plots for the 42 individual maps and as PDF documents on CD. The maps were accompanied by BGS report CR/04/015N, "UK Coal Resource for New Technologies, Final Report". The work was initiated in April 2002 and completed in October 2003. The data was also simplified for inclusion in the Britain Beneath your Feet atlas 2005.

  • During the interpretation of the geological structure of the Sellafield site, a series of 3-D models were created using EarthVision and Vulcan software. These models have been imported into the computer systems operated by British Geological Survey. Geological investigations of the Sellafield and Dounreay areas were undertaken between 1989 and 1997 as part of its programme to determine whether one of the areas might be a suitable location of a deep repository for the disposal of radioactive waste. The Nirex (Nuclear Industry Radioactive Waste Executive) Geological Archive was deposited with BGS in 2000 and BGS have undertaken to retain the records for a minimum of 50 years as part of its national geological archive. The archive has been moved to permanent storage locations and normal BGS arrangements will apply for non-commercial (academic) access to the material. The ownership of NIREX (Nuclear Industry Radioactive Waste Executive) was transferred from the nuclear industry to the UK Government departments DEFRA and DTI in April 2005, and then to the UK's Nuclear Decommissioning Authority (NDA) in November 2006.

  • The SACS and SACS2 projects ran sequentially from 1998 to 2002, with the aim of developing research into the potential for large-scale storage of CO2 in underground saline aquifer formations. SACS and SACS2, focussed specifically on scientific aspects of the Sleipner CO2 injection operation. As well as establishing protocols for conventional geological, geochemical and geophysical characterisation and monitoring, significant effort was put into evaluating requirements for the more holistic discipline of site risk assessment.

  • The BGS collection of downhole CCTV (Closed Circuit Television) recordings and backup tapes for worldwide SKYLAB satellite imagery. CCTV recordings carried out down boreholes, mainly drilled for water, were undertaken by BGS for specific commercial contracts in Great Britain, and may also have associated geophysical data. The collection started in 1997, and the present holdings are 138 videos, with infrequent additions. Video recordings on other topics may be added.

  • Coal resource maps for the whole of the UK have been produced by the British Geological Survey as a result of joint work with Department of Trade and Industry and the Coal Authority. The Coal Resources Map is a Map of Britain depicting the spatial extent of the principal coal resources. The map shows the areas where coal and lignite are present at the surface and also where coal is buried at depth beneath younger rocks. The maps are intended to be used for resource development, energy policy, strategic planning, land-use planning, the indication of hazard in mined areas, environment assessment and as a teaching aid. In addition to a general map of coal resources for Britain data also exists for the six inset maps: Scotland; North-East; North-West; East Pennines; Lancashire, North Wales and the West Midlands; South Wales, Forest of Dean and Bristol. Available as a paper map, flat or folded, from BGS Sales or as a pdf on a CD if requested.
