Summary

Results of particle size analysis (PSA) performed on approximately 29,000 seabed sediment samples collected by BGS from the UK Continental Shelf (UKCS) and adjacent deep water areas, mostly using sediment grabs, but also sediment corers on occasions. Measurements were also made on approximately 8,000 downhole sub-samples from shallow cores and boreholes. Data from other UK organisations have also been added to this PSA dataset. The data are held within the National Geoscience Data Centre (NGDC) as the Marine Environmental Data and Information Network (MEDIN) Data Archive Centre (DAC) for geology and geophysics. Data are delivered via the 'Offshore samples: particle size analysis data' layer on the BGS GeoIndex.
