Abstract
Lacustrine sediment sampling equipment, such as lightweight gravity corers, are limited in operation to relatively shallow water environments (less than 50 m). This is because the ability to control such equipment becomes difficult with increasing water depth. In addition, adverse weather conditions, wind and waves etc. can further limit the success of such operations. The deep water equipment is designed to attach to gravity corers of the Kajak Brinkhurst type, and extend the operating depth by eliminating the need for direct control from the surface. The equipment stabilizes the corer on entry into the sediment and automatically closes the top of the core tube after driving is completed. No changes are required to be made to the corer whose mechanical operation remains the same.
