A piston‐type coring device for unconsolidated bottom deposits is described. The apparatus is a modification of the lightweight Livingstone corer. The coring tube is clear plastic, allowing visual examination of the core before extrusion, and the piston contains a vacuum release tube to prevent expansion of the cored material during removal of the piston. It is easily constructed, requiring no special machining, and is therefore relatively inexpensive compared with other similar coring devices.
