Marine sediment particle size analysis (PSA) data from around the UK (1966 onwards)

Seabed sediment samples were collected by BGS during offshore surveys mainly using grabs, but also sediment corers on occasions (vibrocorers, gravity corers). Particle size analysis (PSA) was performed on approximately 29,000 samples. The dried samples were split into gravel, sand and mud fractions using sieves and the weights were 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. Measurements were also made on approximately 8,000 downhole sub-samples from shallow cores and boreholes. Most test results are available digitally, although there are a significant number of legacy results stored on paper. Data are held within the National Geoscience Data Centre (NGDC). Core material are managed as part of the BGS materials collection and are available for examination, testing or sub-sampling.
