  • The British Geological Survey has collected over 50000 offshore samples using grabs, dredges and shallow coring devices (to a maximum depth of 6m below the sea bed). The collection also includes additional third party data and has assisted in the creation of BGS Marine Geology Maps. The distribution is variable, but in general there are sample stations spaced about every 5 - 10km across the entire UK Continental Shelf (UKCS). In some localised areas the sampling density is much higher. The data held includes digital data and analogue records (sample data sheets), plus associated physical sample material. Sample data sheets which have been scanned contain index information and geological descriptions and are more detailed from 1983 onwards. Coded geological descriptions were entered on sheets which were subsequently digitised, and this information is available for about 10,000 samples. The data also includes results of analyses such as micropalaeontological examination or age dating. Particle Size Analysis, geochemistry and geotechnical data are described in separate metadata entries. Sample material are managed as part of the BGS Materials collection and are available for examination and subsampling. The data are stored within the National Geoscience Data Centre (NGDC) and Marine Environmental Data and Information Network (MEDIN) Data Archive Centre (DAC) for Geology and Geophysics. Data are delivered via the BGS Offshore GeoIndex www.bgs.ac.uk/GeoIndex/offshore.htm.The activity and scan layers contains location information, metadata and links to scanned sample datasheets/core logs, and the geological, geotechnical, geochemical and sea-bed sediment data layers contain observations and/or measurements as digital values. The data are applicable to a wide range of uses including environmental, geotechnical and geological studies. Reference: Fannin, NGT. (1989) Offshore Investigations 1966-87.

  • The Intergovernmental Panel on Climate Change (IPCC) Data Distribution Centre provides four main types of data and guidance: 1. Observed Climate Data Sets; 2. Global Climate Model Data; 3. Socio-economic data and scenarios; 4. Data and scenarios for other environmental changes.

  • Old card index of quarries in England, Wales and Scotland dating mostly from 1939 to 1963: about 7000 cards, each referring to one quarry. England & Wales cards are arranged by BGS 1-inch (now 50k scale) geological sheet, Scottish cards by county. At best, cards indicate county, geol-sheet, rock type, name, grid reference, locality, owner, date of record and cross references to BGS samples.

  • This mineral resource data was produced as part of the Mineral Resource Map of Northern Ireland via a commission from the Northern Ireland Department of the Environment. The work resulted in a series of 21 data layers which were used to generate a series of six digitally generated maps. This work was completed in 2012 with one map for each of the six counties (including county boroughs) of Northern Ireland at a scale of 1:100 000. This data and the accompanying maps are intended to assist strategic decision making in respect of mineral extraction and the protection of important mineral resources against sterilisation. They bring together a wide range of information, much of which is scattered and not always available in a convenient form. The data has been produced by the collation and interpretation of mineral resource data principally held by the Geological Survey of Northern Ireland and was funded via a commission from the Northern Ireland Department of the Environment. These layers display the spatial data of the mineral resources of Northern Ireland. There are a series of layers which consist of: Bedrock: Clay, Coal & Lignite, Coal – lignite proven, Conglomerate, Dolomite, Igneous and meta-igneous rock, Limestone, a 100m buffer layer on the Ulster White Limestone, Meta-sedimentary rocks, Perlite, Salt, sandstone and Silica Sand. Superficial (unconsolidated recent sediments) : Sand & gravel and Peat. The data except for the salt and proven lignite resource layers was derived from the 1:50 00 and 1:250 000 scale DigMap NI dataset. A user guide 'The Mineral Resources of Northern Ireland digital dataset (version 1)' OR/12/039 describing the creation and use of the data is available. A companion set of data with the internal boundaries retained is also available.
