Bottom Sampling Dredge
Stainless steel dredge is used to collect benthic organisms or sediment on soft bottoms (sand or silt). A simple trigger holds the sampler open while lowering to cover a uniform area of approximately 7-1/2 x 5-1/2″ (19 x 14 cm). Scissor design closes the sampler, retrieving a volume of sediment to the surface for analysis. When closed, the sample remains undisturbed as it is raised to the surface. Careful release into a pan distributes sediment approximately as it was on the bottom.
A sturdy harness line is provided with the dredge, which weighs 6 lbs.
