Griffith Corer


The single-drive Griffith corer consists of a simple but robust core head that connects standard polycarbonate tube to Livingstone drive rods. Cores are pushed into the sediment with the rods, and a piston provides the suction needed for recovery. The length of tube and the character of the sediments limit core length, and operation becomes difficult in water deeper than 30m or with core tubes longer than ~3m.
