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) MEDIN 3.1.1
