Bowers and Connelly Mega Corer
|Within Vocab||SeaVoX Device Catalogue|
|Preferred Label||Bowers and Connelly Mega Corer|
|Definition||A sediment corer which collects relatively undisturbed sea-floor sediment samples including an intact sediment-water interface and overlying supernatant water. The Mega Corer holds 12 tubes, each 600 mm in length, allowing collection of sediment cores up to 400 mm long. It has a hydrostatic damping system which is used to slow down the penetration rate and to remove the typical bow wave. Corer deployment rates are in the region of 1 metre per second on the descent, and at any speed on retrieval as the samples are sealed top and bottom. The core tubing can be manufactured from acrylic, poly carbonate or stainless steel. The instrument was designed by Bowers and Connelly and is now manufactured by OSIL.|
