Aquisition

In addition to the pore water squeezers, a pore-water sampling with the new generation of “Rhizone pore water samplers” will be also used on this cruise for the less indurated sediments of the record. This might be a good technique that could save core sample material that would be totally destructed and consumed otherwise (whole round sample). Rhizone samplers are 2.5 mm in diameter and 5 cm in length; they can be inserted into the sediment from the cut face of core segments, or alternatively through tiny holes drilled into the liner like those for temperature measurement. The samples are collected in either 10 mL vacuum tubes designed for medical use or disposable syringes requiring a minimum of experience and maintenance.
