A triple corer has been designed, based on a modification of the Benthos corer. Satisfactory cores have been taken in clay muds, silty clay muds, silts, and glacio‐lacustrine clays at depths up to 250 m. The sediment is extruded layer by layer on a simple screw thread piston device. Results show that extrusion of each tube separately is reproducible, and that it is possible to subsample the cores at close intervals. Bottom water for analysis is also collected by the corer.
