Wet Sediment Samplers
To sample wet sediments it needs to be done in one sample because the hole collapses after the sampler is removed.
The Gouge Auger, the Undisturbed Wet Soil Sampler (UWS), the Piston Sampler and the Russian D-Sampler.
- Gouge Auger
This is designed to take undisturbed samples from very soft and preferably very wet soils. It is a tapered stainless steel tube with one side cut away.
- Piston Sampler
These are available as 2 main versions, the Surface type and the Down Hole type. Both have a moving piston that creates suction inside the sample tube.
- Russian D Sampler
The Russian D-Sampler is used in very, very soft and wet conditions like swamps and can sample at any given depth. The sampler is made from a half-tube (longitudinally) of stainless steel with one pointed aluminium end, a cover flap (blade) and a connection for extension rods.
- Undisturbed Wet Soil Sampler
This sampler is for obtaining undisturbed samples in water saturated materials and retains the sample inside a removable soft clear plastic tube and uses a plastic sample retainer (split fingered one-way valve).
