  • Elevation contour lines within the Severn catchment at 10 metre intervals. Digitised from the scanned topographic maps.

  • This dataset provides the results of a water quality survey undertaken in mid-May 1985 of streams, springs and boreholes associated with the ophiolite rocks of the Troodos Massif in Cyprus. Determinands measured include: Na, K, Ca, Mg, Cl, SO4, Sulphide, Si, Alk, pH, Al, Ba, B, Br, Cr, I, Li, Sr, Fe

  • Chemical analysis of stream, river and rainfall samples for lowland rivers in the UK. The data are uncensored and provide a basis for research purposes, and must be viewed in this light. Information on analytical methodologies is available, including detection limits, from which the user can choose how the data might be interpreted. The basins studied were the Tweed, Wear, Humber, Great Ouse and Thames. One tributary (the Teviot) and two main-stem sites were monitored in the Tweed Catchment. One site around two-thirds down the catchment of the River Wear was monitored. Humber Basin Monitoring was undertaken for all the tributaries especially near their downstream limits. The Great Ouse was monitored around half way down the catchment. The Thames catchment was monitored upstream and downstream of sewage inputs to the river, prior and post effluent stripping of phosphorus. This work formed part of a major UK initiative introduced in the early 1990s, the Land Ocean Interaction Study, LOIS, to examine water, chemical and sediment fluxes from the eastern UK rivers to the North Sea. The entire LOIS core monitoring data, including a wider range of determinands, is available from EIDC. As part of this and subsequent work, the initiative was extended to examine a range of catchment basins, from rural to agricultural and industrial/urban impacted ones.

  • Distribution of soil parent materials in the Severn and Wye catchments. These were mapped during the Soil Hydrology Study conducted by JP Bell in 1968-1969: Bell, J.P. (1969). The Soil Hydrology of the Plynlimon Catchments. Institute of Hydrology Report No. 8, Institute of Hydrology, Wallingford, UK.

  • Elevation contour lines within the Wye catchment at 10 and 20 metre intervals. The contour lines have been digitised from a scanned topographic map.

  • Digital river network of the natural and artificial streams and rivers within the Plynlimon catchments.

  • Trace metal mobilisation data (pH, ALK, Na, K, Ca, Mg, Li, SO4, Si, Be, Mn, Fe, Zn, Cu, Al,Sr, Be, Ba, Y,Co, Ni, B, Rb, Y, Cd, Sb, Cs, Ba, La, Ce, Nd, Pb, Th, U) for the River Carnon, the River Fal (downstream) and its estuary in Cornwall following discharge of highly polluted water from the Wheal Jane mine. In January 1992, there was a major pollution incident involving highly acidic wastes. CEH, in conjunction with the University of Reading monitored the River Carnon between September 1992 and April 1994, to examine the water quality.

  • This document data set contains original prints, on paper, sepia or film, of seismic reflection survey location (navigation) maps. These provide the location data for the seismic sections of the Original Seismic Sections (ORIGSEISECS) and Copy Seismic Sections (COPYSEISECS) datasets. Almost all 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, for academic research. All maps are digitised upon receipt (see LOCSEC database) and then archived in this data set. (Copies used to be used for interpretation purposes but this is no longer the case.) Documents stored rolled in tubes. Approx 800 maps.

  • A collection of regional geochemical data, mainly from stream sediment surveys, gathered from many BGS overseas projects since 1960s. Some areas are well covered and well documented with data available digitally on CD-ROM. Projects from 1960s and 1970s generally have no digital data and information exists only in paper form.

  • All type and figured calcareous microfossils and palynmorphs held in the BGS collections are registered using the prefix 'MPK'. To date MPK1 to 13400 have been used. Information includes name, locality, geological details and journal details.
