SAMPLING TECHNIQUE OF PISTON GRAVITY CORER
Abstract:
The piston gravity corer is a fine instrument to sample sedimental core at sea. It’s penetrating depth depends on the weight and shape of the instrument, the distal velocity of the instrument during its free falling in sea water and the sedimental resistance. A good sampling core can be obtained by knowing both the performance of the instrument and the during existing conditions of the sea and the sediment.
