The impact of the messenger triggers the spring-loaded jaws to close. A two-way mechanism prevents accidental closure while the dredge is dropping. The dredge is placed onto the bottom sediment, then closed and pulled up to retrieve a sample. They provide samples from which the sediment profile can be described.Ī bottom sampling dredge consists of two halves of a relatively small box.
