| Definition | A box corer for sampling of interfaces without disturbance in a range of sedimentary areas. The corer generally samples the underlying sediment to a depth of 20-60cm. The corer consists of a stainless-steel box, 30cm square and 120cm in length. The weight of the corer is 600kg, including 20 removable weights totalling 200kg. On one side the box is provided with two long Perspex windows for initial observation of the core, in the other side there are small sampling ports down the length of the box. The box corer is deployed from, and recovered to, a stand which is bolted onto the working deck. The stand keeps the corer in the upright position. The corer is deployed with the shovels in the fully open position, and at a speed determined by the type of sample and type of sediment. When the corer hits the bottom, the no-load release is activated, the warp is then hauled slowly closing the shovels and lifting the corer from the bottom. | ||
