Magnetics Tellus Survey 2005 - 2006 Geophysical data were collected in 2005 and 2006 by the Joint Airborne-geoscience Capability (JAC), a joint venture between the Finnish Geological Survey (GTK) and the British Geological Survey (BGS). Magnetic, electromagnetic and terrestrial gamma-radiation (radiometric) data were recorded. Data were acquired for 80,458 line km of survey. Flight lines were spaced 200 m apart in the direction 165-345 degrees. The survey was flown with a nominal ground clearance of 56 m in rural areas and 240 m in urban areas, with sample intervals of 7 m (magnetics), 17.5 m (electromagnetics) and 70 m (gamma radiation).

Records of all onshore Northern Ireland boreholes, trial pits, shafts and wells held in the Geological Survey of Northern Ireland archives. The records range from simple single page lithological logs through to hydrocarbon completion reports. They are approximately 24,000 records dating back over 200 years and ranging between one and several thousand metres deep. New records are being added to the collection each year. A small percentage of the borehole records are held commercial-in-confidence for various reasons, and cannot be released without the written permission of the originator. GSNI staff will release the data where this is possible or provide you with the information needed to contact the originator.

[This metadata record has been superseded, see http://data.bgs.ac.uk/id/dataHolding/13480158] The Geophysical Borehole Log index provides details of all digital geophysical logs available to BGS. The database provides the borehole metadata related to logging and metadata for the logging itself and log data stored in a proprietary hierarchical database system (PETRIS RECALL). Contains most digital geophysically logged bores known to BGS National Geological Records Centre. Scattered distribution of boreholes, locally dense coverage, relatively few logs from Scotland & Central Wales, increasing data density on UK continental Shelf.

We collect data from sensors located throughout the UK and beyond capturing information on properties such as groundwater temperature and levels, barometric air pressure and motion sensors. We have recently started collecting information related to the energy efficiency of buildings and have developed techniques for incorporating data from sensors operated by other institutions. Some of the data we collect is available through the sensor API and sensor dashboard which provides easy access to the API data.

Tellus Water Tellus Drainage The drainage dataset contains stream waters and stream sediment analysis and are a combination of two surveys. The first, the G-Base survey, was carried out between 1994 and 1996 in the west of Northern Ireland. In 2005 and 2006 a second survey was carried out as part of the Tellus project in the areas not covered by the original survey. Stream waters The G-Base samples (1994-1996) were analysed for the following anions and fluid parameters: Bicarbonate, Chloride, Fluoride, Nitrate, Sulphate, Dissolved Organic Carbon, Conductivity, pH. Samples were analysed for the tracer elements Ag, Al, Al, As, B, Ba, Be, Ca, Cd, Ce, Co, Cr, Cu, Fe, K, La, Li, Mg, Mn, Mo, Na, Ni, P, Pb, Rb, Sb, Se, Si, Sr, Tl, U V, Y, Zn, Zn, Zr. The Tellus samples (2005-2006) were analysed for the following anions and fluid parameters: Bicarbonate, Bromide, Chloride, Fluoride, Nitrate, Nitrite, Orthophosphate, Sulphate, Dissolved Organic Carbon, Alkalinity, Conductivity, pH. Samples were analysed for the trace elements Ag, Al, As, Au, B, Ba, Be, Bi, Ca, Cd, Co, Cr, Cs, Cu, Fe, Hg, Ho, K, La, Li, Mg, Mo, Mn, Na, Ni, P, Pb, Pd, Pt, Rb, Rh, Sb, Se, Si, Sn, Sr, Th, Tl, U, V, Y, Zn, Zr. The surveys followed the British Geological Survey's Geochemical Baseline Survey of the Environment (G-BASE) standard developed over many years that defines the specifications for mapping the regional geochemistry of the United Kingdom.

Hourly and minute means of the geomagnetic field vector components from observatories around the world from, respectively, 1883 and 1969, to the present day. At present there are about 160 observatories. These data are useful for tracking changes in the magnetic field generated inside and outside the Earth. Data are produced by a number of organisations around the world, including BGS. Data are available in plain text from www.wdc.bgs.ac.uk.

Tellus Soils For rural soils, samples were collected at an interval of approximately one site per 2 km2 (about one site every 500 acres). Samples were collected from two depths (20 cm and 50 cm) at each site to provide an insight into vertical geochemical variations. The samples were analysed by XRF for Ag, Al2O3, As, Ba, Bi, Br, CaO, Cd, Ce, Cl, Co, Cr, Cs, Cu, Fe2O3, Ga, Ge, Hf, I, In, K2O, La, MgO, MnO, Mo, Na2O, Nb, Nd, Ni, P2O5, Pb, Rb, SO3, Sb, Sc, Se, SiO2, Sm, Sn, Sr, Ta, Te, Th, Tl, TiO2, U, V, W, Y, Yb, Zn, Zr. Au, Pt and Pd were analysed by 10g Fire Assay SO4 by Aqua Regia ICP-MS pH and Loss on Ignition were also recorded. The surveys followed the British Geological Survey's Geochemical Baseline Survey of the Environment (G-BASE) standard developed over many years that defines the specifications for mapping the regional geochemistry of the United Kingdom.

This map layer shows the distribution of superficial deposits, as mapped at 1:250 000 scale, which are considered to have the potential to store and transmit significant amounts of groundwater. The areas defined are based upon a sub-set of superficial deposits as mapped by GSNI at 1:250 000 scale where the following mapped deposits are considered to have potentially significant permeability and storage properties: glacial sands and gravels, blown sand, raised beach deposits and alluvium. A regional, detailed assessment of the individual deposits in terms of their aquifer potential (aerial extent, thickness, saturated depth etc.) has not yet been undertaken. Hence formal classification of each deposit as an aquifer area is not possible at present. In some cases limited aerial extent or minimal thickness may result in the mapped geological deposit not being considered as an aquifer. Due to natural geological variability and data availability, this map cannot and is not intended to represent actual conditions on a site-specific scale. For site specific investigations more detailed geological and hydrogeological information is available from GSNI. Advice on groundwater management and protection matters is available from the GSNI hydrogeologist or by contacting the Groundwater Team at NIEA. Further information on the hydrogeology of Northern Ireland is available in Hydrogeology of Northern Ireland, Robins N S (1997) and Hydrogeological Map of Northern Ireland, BGS 1994 both of these are available from the BGS bookshop or from the GSNI office (note: the aquifer classification used on the 1994 hydrogeological published map differs from the classification shown on the GeoIndex layer). NOTE: When considering the distribution of aquifers within a certain area, reference should also be made to the bedrock aquifer layer, available on this website.

Database of palaeontological specimens, world-wide coverage, including both "Museum" and "Survey" fossil collections from Keyworth and Edinburgh. Development commenced in Autumn 2000 and is ongoing. The database currently contains over 100,000 entries, including half of the taxonomic reference collection held at BGS Keyworth. Internet search access is available on the BGS web site. Key fields in the dataset, many of which can be searched for, include, sample number, nature of sample, confidentiality, collector/donator & year, register details, locality information (including grid reference, map sheet etc.), stratigraphy, type status, identifications & authority and publication details.

Scanned images of the records of onshore Great Britain (or near shore) site investigation reports held in the BGS archives in paper, microfilm or digital format. The entire collections in BGS Edinburgh have been scanned, but in BGS Keyworth currently only new reports received since 2002. Scanning started in 2002 and is ongoing with new records being scanned and added to the collection. Images are stored in TIFF format (Tagged Image File Format). Indexed on the site investigation database and the boreholes within the report, and their images, are associated via the borehole database.
