Components
The multi corer comprises of an array of 12 transparent polycarbonate core tubes with a diameter of 66 mm that are fixed to core holders and the coring head with double lock-clamps. The coring head is attached with a cardanic suspension to a rack consisting of inclined legs that are held together by horizontal steel bars. This enables vertical penetration of the sample tube into the sediment. The coring head is hydraulically damped to ensure undisturbed samples. Penetration into sediment is controlled by detachable lead weights at the top of the coring head. If required, a video camera and light sources may be attached (see also: TV-guided Multiple Corer (TV-MUC) https://spaces.awi.de/confluence/pages/viewpage.action?pageId=183566359
