Lineage

The grab system comprised a 0.1 m ^... mini Hamon grab fitted with a video camera, the combined gear being known as a HamCam. This allowed an image of the undisturbed seabed surface to be obtained for each grab sample Hamon Grab samples were collected at 44 sites within Holderness Inshore Marine Conservation Zone during survey CEND0812. But only 40 sample were sufficient for analysis. 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.
