Hongve Corer

Description

The Hongve corer (Hongve, 1972) is a lightweight, mini gravity corer, easily carried by hand and deployed in remote field locations for recovering an undisturbed sample of the uppermost sediments. Its core barrel is ~2cm wide and 15cm long, and is stored inside the core head during transport. The corer is deployed with a rope, and lowered into the sediment under its own weight, or if more weight is needed, pebbles or other materials found at the field site can be placed in the core head. A one-way ball valve at the top of the core barrel provides the suction needed for recovering cores.
