Sampling positions were recorded (fixed) using Hydropro data acquisition software when the gear made contact with the seabed, and the mid-point of the vessel’s stern gantry was used as the default offset for position fixing. On recovery, a photograph was taken of the undisturbed surface and the depth of material within the grab was measured using a probe. A sample depth of 5 cm was required to qualify as a valid sample. The sample was inspected to measure the depth of the apparent Redox Potential Discontinuity (aRPD) or ‘black layer’, if present. A 100 ml sub-sample was then removed for Particle Size Analysis (PSA), using a 3 cm diameter core driven to the full depth of the grab. The remaining faunal sample was then processed by washing over a 1.0 mm sieve. The retained material was photographed and preserved in a buffered 8% formaldehyde solution for transfer ashore to a specialist laboratory for analysis. A minimum of three attempts was made at each station to obtain a valid grab sample before the station was abandoned. Samples were considered invalid where loss of sample occurred during recovery of the grab, due to large sediment particles preventing closure of the bucket. Samples of < 5 cm depth were ordinarily discarded. However, when it was found to be difficult to obtain a valid sample, then a sample with < 5 cm material was retained, at the discretion of the lead scientist. MEDIN 3.1.1
