Barnett-Watson multiple corer
|Within Vocab||SeaVoX Device Catalogue|
|Alternative Labels||SMBA multicorer|
|Definition||A corer designed at SMBA (current name Scottish Association for Marine Science) that collects multiple undisturbed samples of the upper sediment, flocculent material and overlying water. This is achieved by a hydraulically-damped controlled descent of the open core liners once the frame has landed on the seabed. Rubber seals at the top and bottom of the core liner prevent sample loss during recovery. The outer framework supports weighted arrays of polycarbonate liners (4 split liners of 10cm internal diameter and 8 split liners of 6 cm internal diameter) hanging from a water-filled dashpot.|
