  • Water weighted corer
    Patent number: 3970156
    Abstract: A water-weighted corer comprising a cylindrical tank mounted concentrically n a core barrel intermediate the coring tube and the shackle is provided. The tank has a water inlet at its bottom and an air vent at its top so that during descent water enters the tank through the bottom inlet, forcing air out the top vent. During free fall the falling speed imparts a substantial amount of kinetic energy to the water mass in the tank, providing the driving force required for the corer to penetrate deeply into a sediment bed.
