For the BACI study, a mini Hamon grab fitted with a video camera and lighting was available to collect sediment samples for infauna community analysis when the Day grab was unsuccessful. A Shipek grab was also available to collect sediment samples in conjunction with the mini Hamon or Day grab. For the fishing pressure gradient study, the 0.1 m2 Day grab was the only gear deployed to collect sediment samples. All grab systems were deployed from the side gantry. Samples were collected from within a 50m radius ‘bull ring’ around the target sampling location. On recovery of the grab, a photograph of the sample was taken (in situ for the Day and Shipek grabs and following transfer to a large container for the mini Hamon grab). The sampling depth (Day and Shipek grab) or volume (mini Hamon grab) was estimated before a sediment subsample was collected for particle size distribution analysis (PSA) using either a 3cm diameter core (Day and Shipek grab) or a 125ml scoop (mini Hamon grab). Sediment sub samples for PSA were placed in labelled containers and frozen immediately. The remaining sample was decanted into a plastic box and transferred to the sample processing area on board the vessel if an infaunal sample was required. Benthic fauna were collected by washing the sample with sea-water over a 5mm and 1mm sieve. The retained >1mm fraction was transferred to a labelled container and preserved in 4% buffered formaldehyde for later analysis ashore. A visual assessment was made of the sediment type sampled by the grab and noted on the field records, assigning the sample to a Broad Scale Habitat (BSH) as per the MCZ Project Ecological Network Guidance document (Ashworth et al 2010).
