Box-shaped sediment sampler with spring-loaded jaws
The Bottom Sampler acc. to Ekman-Birge is a quantitative sampler with precise sampling area to achieve nearly undisturbed samples in soft grounds. It consists of a sturdy-walled metal cabinet equipped with two spring-loaded jaws which are released by a messenger. Two light plates cover the top opening of the sampler to prevent the sample from being washed out during ascent.
