Samples were collected at 8 sites within the Selsey Bill and The Hounds Marine
Conservation Zone on survey 2EYX70914
A Day grab, with a surface sampling area of 0.1 m2 was deployed from the
stern gantry of the survey vessel to recover sediment from the seabed.
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.
