The Geological Survey of Northern Ireland (GSNI) and the British Geological Survey (BGS) completed a regional geochemical survey of Northern Ireland's soils between 2004 and 2006. Sampling and quality control were undertaken according to the G-BASE protocol of BGS. 6,862 sites were sampled (at depths of 20 cms and 50 cms) an average of one site per 2 km2. This dataset are the results of Trace Element Analysis by ICP-OES and ICP-MS following Aqua Regia Digest of deep soils (50 cms) presented as a point shapefile.
