Bottom Dredge

AMS bottom dredges are primarily designed for sampling sand and silt, but can be made to sample most types of non-cohesive material, except hard-packed clay. They provide samples from which the sediment profile can be described.


A bottom sampling dredge consists of two halves of a relatively small box. The dredge is placed onto the bottom sediment, then closed and pulled up to retrieve a sample. A two-way mechanism prevents accidental closure while the dredge is dropping. The impact of the dredge on the bottom surface triggers the spring-loaded release mechanism.
