Stream sediment geochemistry (500m Grid) dataset

This dataset represents the first publication of complete national maps from the Geochemical Baseline Survey of the Environment (G-BASE) and TellusNI projects, whose aim was to conduct a national geochemical survey of the United Kingdom in order to improve understanding of our geology and environment and provide quantitative evidence against which to gauge future environmental change. This dataset consists of a series of interpolated raster (ASCII grid) maps displaying the concentrations of a suite of chemical elements (and oxides) in the stream sediments of the United Kingdom. The chemical elements are as follows: Arsenic, Barium, Calcium (CaO), Chromium, Cobalt, Copper, Iron (Fe2O3), Lanthanum, Lead, Magnesium (MgO), Manganese (MnO), Nickel, Potassium (K2O), Rubidium, Uranium, Vanadium, Zinc and Zirconium.

Statement

The source data for the product is; -Stream sediment analytical data generated by the G-BASE Project (and its predecessors) of the British Geological Survey between 1968 and 2013. -Stream sediment analytical data generated by the Tellus NI Project of the Geological Survey of Northern Ireland between 1994 and 2006. Throughout the lifetime of the G-BASE and Tellus NI projects, strict quality control procedures have been in place at all stages from sample collection to analytical data reporting. Analytical data have been closely monitored to ensure continuity during numerous field campaigns and between different analytical methods. All data have been conditioned with respect to primary reference materials in order to provide both accurate and precise element concentrations with a high degree of confidence. The data in the BGS_SedGC_500m dataset has been interpolated from the original stream sediment geochemistry point sample data using ordinary kriging. Each chemical element is presented as a national model of elemental concentration and includes a model of uncertainty (derived by the kriging process). The sample site data for G-BASE and TellusNI are available on request from BGS, and are provided in British National Grid or Irish National Grid coordinates as relevant. Further details can be found on the BGS website ( http://www.bgs.ac.uk/gbase/sampling.html).
