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. .. _`https://www.eea.europa.eu/themes/water/interactive/by-category/wfd`: https://www.eea.europa.eu/themes/water/interactive/by-category/wfd MEDIN 3.1.1
