Subsampling systems for obtaining undisturbed samples from pristine deep-sea sediment cores containing gas hydrates

The ARS (Autoclave Rod Sub-sampler) facilitates investigations of samples taken by the MAC-A (Multi Autoclave Corer ANAXIMANDER) without demolishing the in situ conditions (temperature, pressure). Its maximal operational pressure is 250 bar.

It is coupled to the ball-valve equipped MAC-A pressure vessel and induces an investigation rod which can be furnished with different examination tips. Depending on the tip either physical parameters (e.g. shear resistance, sample length&) or sub samples (e.g. water, sediment&) can be taken. The main sample inside the pressure vessel persists almost undisturbed after the intervention.
