Samples were collected from within a 100 m radius around the target location. For station CGT2 the sample was collected away from the planned station due to an oil and gas installation exclusion zone. The sample depth in the day grab was taken to estimate the volume of the sample. A sediment core was then taken from the sample and stored in a plastic tub for Particle Size Analysis (PSA) in the laboratory. The remaining sample was emptied in a plastic box and transferred to the sample processing area onboard the vessel. Benthic fauna were collected by washing the sample with sea-water over a 5mm and 1 mm sieve. The retained >1 mm fraction was transferred to a labelled container and preserved in 4% buffered formaldehyde for later analysis ashore. For two stations Deep2 and Deep5 the Hamon Grab with a surface sampling area of 0.1 m2, was deployed 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 4% buffered formaldehyde for later analysis ashore. MEDIN 3.1.1
