Lineage

Samples were collected by 0.1 sq m box core (NIOZ design) which was then subsampled using smaller cores. These were extruded to separate the 0-5 and 5-10 cm depth horizons which were then subject to PSA analysis in 0.5 Phi size classes, using standard procedures combining wet sieving, dry sieving and laser sizing, (Malvern mastersizer). Results give PSA distribution from -5.5 Phi (45 mm) to +11 Phi (0.49 μm). Summary statistics (% gravel, sand and silt/clay) and univariate indices of distribution (Mean, Sorting, Skewness, Kurtosis) were determined using GRADISTAT (Blott, S.J. and Pye, K. (2001) GRADISTAT: a grain size distribution and statistics package for the analysis of unconsolidated sediments. *Earth Surface Processes and Landforms* 26, 1237-1248) Records include data from Defra funded project ME5301 entitled 'Mapping the structure, function and sensitivity of seabed sediment habitats to support assessment of the sea-floor status and the broadscale monitoring and management of the benthic environment' which sampled locations in the North Sea and western English Channel.
