Hamon Grab samples were collected at 21 sites within Dover to Folkestone Marine Conservation site on survey SVGL0712. A Mini-Hamon Grab with a sampling area of 0.1 m <sup>...</sup> , was deployed from the stern gantry of the vessel to collect sediment from the seabed On recovery, the grab was emptied into a large plastic bin and a representative sub-sample of sediment (approx. 0.5 litres) taken for Particle Size Analysis (PSA). The sample was stored in a labelled plastic container and frozen ready for transfer to a laboratory ashore. The remaining sample was photographed and the volume of sediment measured and recorded. Benthic fauna were collected by washing the sample with sea water over a 1 mm sieve. The retained >1 mm fraction was transferred to a labelled container and preserved in 8% buffered formaldehyde for later analysis ashore. Four grab samples were collected for infauna analysis from stations DovF01, 13, 18 and 23 within the Dover to Folkestone rMCZ . The sediment was found to vary across the rMCZ area, with sand, mud, mixed and coarse habitat types represented. Eight stations surveyed with the Mini-Hamon grab produced samples with a volume less than the minimum required (<5 litres). The small volume of material collected could indicate the presence of rock covered with a thin layer of sublittoral sediment.
