  • This data was produced to support a project looking at low permeability rocks in sub-Saharan Africa. Multiple boreholes were drilled for the project with geology identified from chippings. Groundwater chemistry was analysed from the resulting boreholes. The data contained within this record is from the CD that accompanies the report: J Davies and B É Ó Dochartaigh. 2002. Low Permeability Rocks In Sub-Saharan Africa. Groundwater development in the Tabora Region, Tanzania. British Geological Survey Internal Report, CR/02/191N. 71pp http://nora.nerc.ac.uk/id/eprint/505608/1/CR_02_191N.pdf The CD has not been uploaded in full elsewhere.

  • The composition of the air present over the Weybourne Atmospheric Observatory (WAO), situated on the north Norfolk coast, depends on its origins. Plots showing the footprints of 10 day back trajectories arriving at WAO have been calculated using the UK Met Office's NAME Lagrangian atmospheric dispersion model.

  • Derived from data collated from the 2005 Aggregate Minerals Survey, carried out by BGS for the Department for Communities and Local Government (CLG) which provide an in-depth and up-to-date understanding of regional and national sales, inter-regional flows, transportation, consumption and permitted reserves of primary aggregates for England and Wales. The information is used to monitor and develop policies for the supply of aggregates. This data set depicts the flow of crushed rock aggregate between the regions of England and Wales. The data originator also has similar data for sand and gravel and also the same data derived from the 1997 and 2001 Aggregate Minerals Surveys.

  • Longterm Meteorological observations (temperature, relative humidity, pressure, wind speed and direction, solar irradiance) at the Weybourne Atmospheric Observatory (WAO). WAO, situated on the north Norfolk coast, is part of the School of Environmental Sciences at the University of East Anglia (UEA) and is a world class facility for fundemental research, background atmospheric monitoring and teaching purposes. WAO operates a range of instruments in its measurement programme - the data from which is archived at the BADC.

  • The University of Wales, Aberystwyth, 1290mhz mobile wind profiler - now referred to as the University of Manchester mobile wind profiler - was operated at the Mace Head Research Facility in County Galway, Ireland, as part of the North Atlantic Marine Boundary Layer EXperiment (NAMBLEX) field campaign in August 2002. During this period the mobile wind profiler obtained vertical profiles of the horizontal and vertical wind components. For each signal beam profiles of the signal to noise (SNR) ratio and spectral widths were also taken.

  • This data was produced to support a project looking at low permeability rocks in sub-Saharan Africa. Multiple boreholes were drilled for the project with geology identified from chippings. Groundwater chemistry was analysed from the resulting boreholes. The data contained within this record is from the CD that accompanies the report: J Davies and J Cobbing, 2002. An assessment of the hydrogeology of the Afram Plains, Eastern Region, Ghana.

  • Regional property grids of the Utsira Sand based on mapping from 2D regional seismic lines and geophysical logs. Grids include: Top Utsira depth, Base Utsira depth, Utsira isopach, Utsira porosity, Utsira porosity effective thickness, Utsira proportion clean sand. 2 km grid spacing. SACS/SACS2 EU project.

  • The BGS Geoscience Thesaurus contains approximately 6000 descriptor terms for concepts in the geoscience and related subjects. Some entries have scope notes to further explain the term. The original source of the data was the Australian Mineral Foundation thesaurus of geoscience; some terms have been added or updated to suit BGS needs and the content will continue to be updated as required. The thesaurus includes synonyms to descriptor terms, hierarchical relationships, symmetric (see also) relationships and lapsed (deprecated) term replacements.

  • This data set details soil pH values and soil moisture values from experimental plots at a field site at Sourhope, Scotland, between 1998 and 2002. Data were collected as part of the NERC Soil Biodiversity Thematic Programme, which was established in 1999 and was centred upon the intensive study of a large field experiment located at the Macaulay Land Use Research Institute (now the James Hutton Institute) farm at Sourhope in the Scottish Borders (Grid reference: NT8545019630). During the experiment, the site was monitored to assess changes in above-ground biomass production (productivity), species composition and relative abundance (diversity).

  • The data set comprises biomass values and mineral nutrient values from experimental plots located at Sourhope, Scotland. On 5 occasions throughout each of the 1999, 2000, 2001 and 2002 growing seasons, grass cuttings were collected from a 50 x 50 cm cell area from each of the 4 main sub-plots within each of a set of experimental main-plots, and biomass values calculated. In addition, mineral nutrient analysis was carried out for the July 1999 grass cuttings. The work was part of the NERC Soil Biodiversity Thematic Programme, which was established in 1999 and was centred upon the intensive study of a large field experiment located at the Macaulay Land Use Research Institute (now the James Hutton Institute) farm at Sourhope in the Scottish Borders (Grid reference: NT 8545 1963). During the experiment, the site was monitored to assess changes in above-ground biomass production (productivity), species composition and relative abundance (diversity). The primary aims of the Programme were to achieve simultaneously an understanding of the biological diversity of the soil biota and the functional roles played by soil organisms in key ecological processes. In seeking to achieve these aims, 24 separate research projects were funded to study soil structure, soil processes (such as the carbon and nitrogen cycles) and the roles of micro-fauna and flora (Bacteria, Nematoda, Protozoa and Fungi), microarthropods (including Collembola and Acari), invertebrate root feeders (Tipulid, Bidionid and Scarabeid larvae), meso-fauna (such as Enchytraeidae) and macro-fauna (including Megadrili, Mollusca and Coleoptera).
