Abstract

A design is presented for a pressure equalization conduit to eliminate suction at the lower end of seafloor coring devices during extraction from the bottom. Tests performed in 1967 indicated that the conduit can minimize core disturbance that is otherwise induced by the suction created during removal of the corer from the seabed.
