These catchment boundaries define upland catchments and subcatchments at the headwaters of rivers Upper Hafren (Severn) and Upper Gwy (Wye). They identify the area of study of the Plynlimon research catchment project.
Collection of c.5,000 items relating to economic mineral exploration and exploitation in Scotland (with some records for Northern England) pre c.1960. Incorporates Non-Ferrous Metallic Ores Committee and Mineral Development Committee records. Collection originally arranged by mineral commodity, but new data is added in accession order.
This index is a list of specimens and slides taken from the John Smith Collection and placed in the Type and Stratigraphical (T&S) Collection of Scotland and Northern England. To some extent it is the digital equivalent to part of the T&S analogue card index which is held in BGS Edinburgh. The data, however, appears to have been derived from the 5 leather bound volumes of the T&S register. The latter are held in BGS Keyworth, but equivalent information (microfilm and paper records) is held in BGS Edinburgh. The MS Access database (BGS_SMITH_GSE) contains 1123 records, it links the T&S register with that of the John Smith Collection (8 bound volumes held at BGS Edinburgh) and provides limited information on taxonomy, nomenclatural status and chronostratigraphy. It also has provision for stating where the specimen is housed. The repository of BGS John Smith specimens is the Edinburgh office.
The dataset comprises plans of various types relating to mining activity, including abandonment plans, gathered since the 1800s. Most were collected as part of the BGS mapping programme and the type and amount of data available will vary considerably. The coverage for Northern England and Scotland is more comprehensive than for the rest of the country. The plans include working copies, compilations and interpretations which may be copyright or confidential. The general nature of some of the plans means that they may not be applicable to a specific site. Current holdings over 60,000.
The object of the scoping study was to assess the feasibility of creating a BGS International Minerals Data Library by first reviewing the nature and extent of minerals-related data holdings accumulated by BGS overseas projects in the last 35 years. Other important considerations such as data quality, utility and ownership are also addressed. Minerals-related information is regarded as geological, geochemical and geophysical data which have relevance in mineral exploration, prospect assessment, resource evaluation and ore deposit exploitation. This includes surveys and multidisciplinary studies on all scales and covering a wide range of disciplines/methodologies. The only aspects that are specifically excluded from the inventory are those projects that deal solely with hydrogeological investigations, development of hardware, software and laboratory techniques, training, institutional restructuring and management. This report lists the information holdings and their various formats summarised on a geographical basis and puts forward a proposal for the development of a digital BGS International Minerals Data Library for Industry and Government.
Microfossil samples submitted to the BGS biostratigraphy laboratory are currently registered using the prefix 'MPA'. Samples include rock, residues from sample preparations, and slides of mounted specimens. Rock, residues and slides from the same sample all bear the same unique identifying sample number. The numbers MPA 1 to 54400 have been used, but this grows steadily. There are currently 21 volumes of registered samples. The value added dataset comprises data for each sample held in the sample register, including collectors' symbols and numbers, 1:10k (or 6") OS quarter sheet, NGR, 1:50k (or 1") geological sheet, borehole name and depth (if relevant), locality, geological formation and report numbers. The value added dataset also includes identifications of specimens on each slide, which are listed on logging sheets and are held separately.
This document data set contains paper copies of many of the seismic reflection survey sections from the original seismic sections data set (ORIGSEISECS) . These have been made for interpretation. Most 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 (British Institutes Reflection Profiling Syndicate ), for academic research. The documents are dyeline prints or plain-paper photocopies. They are stored folded in boxes, approx 40 sections per box, approx 530 boxes. There are a lot of duplicates, there being an interpreted and uninterpreted copy of many profiles. Mostly concentrated in areas prospective for coal, oil and gas.
New acquisitions of all forms of geological data received from external organisations are recorded in the accessions database and the digital or analogue data itself is then available to users. Data is in the form of reports, plans and digital information. This information comes from a wide variety of sources, including public bodies and agencies and commercial organisations. The data itself will be incorporated into existing corporate collections or may form a new collection in its own right. The rate of transfer will depend on priorities and requirements of both internal and external users. Data is continuously removed from the collection, all except recently received material will have been processed.
Collection of individually registered specimens and cuttings from onshore boreholes drilled in England and Wales by BGS, commercial and public bodies since the establishment of BGS in 1835. The collection has been developed as part of the BGS responsibility to establish and maintain a National Borehole Collection. The collection is updated on a daily basis by the addition of new data and by the modification of existing data. The collection contains all registered borehole samples for England and Wales, Scottish borehole samples are excluded. Details of the collection are held on the 'Borehole Materials Database', and may be accessed over the internet from the BGS web site.
The spreadsheet gathers the data collected during two experiments conducted on a synthetic sandstone core sample to assess geophysical monitoring techniques, storage capacity evaluation and the geomechanical integrity of shallow CO2 storage reservoirs. The tests were conducted in the rock physics laboratory at the National Oceanography Centre, Southampton, during 2016, as part of the DiSECCS project with funding from the United Kingdom's Engineering and Physical Sciences Research Council (EPSRC grant EP/K035878/1) and the Natural Environment Research Council (NERC). One experiment was a steady state brine-CO2 flow-through test (so called BTFT in the spreadsheet) to simultaneously evaluate storage capacity and identify pore fluid distribution and mechanical indicators during CO2 geosequestration. The confining and pore pressure conditions were similar to those estimated for shallow North Sea - like storage reservoirs, but simulating inflation/depletion cyclic scenarios for increasing brine:CO2 fractional flow rates. The second experiment focused on the assessment of geomechanical changes (the so called GAT in the spreadsheet) during and after CO2 storage activities under the same stress conditions. The data include ultrasonic P- and S-wave velocities and their respective attenuation factors and axial and radial strains in both tests, and electrical resistivity in the case of the flow-through test.
