WebAt the bottom of the corer tube a piston (pos. 8) with a leather seal is positioned. The piston is connected to the releaser (pos. 1) by a ø8 mm AISI 316 stainless steel wire. During operation the corer tube (pos. 9) is released 1.7 meter above the sediment as the releaser weight reaches the sediment surface. WebAug 1, 2003 · It is suggested that heavier piston corers, deployed on longer, lighter cables, are prone to greater over-sampling ratios over longer stratigraphic intervals, due to the increased likelihood and extent of cable rebound. Cable rebound may also give rise to double penetration of gravity corers, resulting in repeated stratigraphic intervals.
