Kasten Corer (Long Box Corer)

During the SO106 cruise a kasten corer was used once in each of the different working areas (see DISCOL/ATESEPP) to provide sampling material, especially for the pore water and geochemical analyses of the FEMILIEU subproject. The kasten corer consists of a 5 m long box corer, which is attached to a 3.0 t lead weight. The recovered core covers an area of 30 x 30 centimeters. The kasten corer in principal is operated like a gravity corer.
