A new sediment trap system

Abstract

A new sedment trap system intended for use in lakes and marine coastal and shelf areas is presented. The system is designed to (1) keep the sediment collection tubes in a steady vertical position, (2) avoid contamination of the samples by material detached from overhead rigging, (3) fachtate quick exchange of collection tubes at sea, and (4) provide duplicate samples. In situ experimental studes, SCUBA &ving observations, and several years of field use support the reliability of the sedment trap system developed.
