Title

North Sea Sediment Particle Size Analysis

Abstract

Particle Size Analysis (PSA) for seabed sediment samples collected in the North Sea during three Cefas cruises on RV Corystes (Cruise Codes CORY 10/2001, CORY 09/2002 and CORY 8x/2003) as part of a study on sediment biogeochemistry under Defra project A1224 in the period 2001 - 2003.

Quality and validity

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, freeze drying 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)
