Marine Sediment Particle Size Data from around the UK (1966 Onwards)
The data set consists of the results of particle size analysis (PSA) performed on approximetaly 29,000 sea-bed sediment samples collected by BGS from the UK Continental Shelf and adjacent deep water areas, mostly using sediment grabs, but also sediment corers on occasions. Measurements were also made on approximately 8000 downhole sub-samples from shallow cores and boreholes. Data from other UK organisations have also been added to the PSA dataset. The data are stored as part of the National Geoscience Data Centre (NGDC) and the Marine Environmental Data and Information Network (MEDIN) Data Archive Centre (DAC) for Geology and Geophysics. Data are delivered via the BGS Offshore GeoIndex www.bgs.ac.uk/GeoIndex/offshore.htm Seabed Sediment Data layers.

Seabed sediment samples were collected by BGS during offshore surveys mainly using grabs, but also sediment corers on occasions (vibrocores, gravity cores). Particle size analysis was performed on approximately 29,000 samples. The dried samples were split into gravel, sand and mud fractions using seives and the weights recorded. The carbonate content of each fraction was then measured. The grain size of the sand fractions from a subset of the samples has been analysed in more detail at either whole or half phi intervals. For some locations more detailed measurements were made for both the gravel and sand fractions also. Measurements were also made on approximately 8000 downhole sub-samples from shallow cores and boreholes. Most test results are available digitally, although there is still a significant amount of legacy results stored on paper. Data are stored as part of the National Geoscience Data Centre (NGDC). Core material are managed as part of the BGS Materials collection and are available for examination, testing or subsampling.
