Title

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

Abstract

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.

Lineage

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.
