| Definition | The SMBA (Scottish Marine Biological Association) box corer is designed to take an undisturbed sediment sample of 600mm square, up to a maximum depth of around 450mm. The corer consists of a sample box mounted on gimbals, and a spade assembly. The box corer is lowered onto the seabed on a wire at a controlled rate until its frame rests on the bottom. The sample bucket is forced into the sediment by the weight of the corer. As the corer is slowly pulled out of the sediment, a mechanism allows the spade to swing below the sample box sealing in the sediment. Simultaneously, spring loaded flaps above the sample box are closed to prevent the sample being disturbed during recovery. The use of this equipment is very dependent on the type of sediment to be sampled and the current sea state. | ||
