Jumbo (Giant) Piston Corer (18m-60m)



The increased penetration depth of the Jumbo (or Giant) Piston Corer has made it an important tool in the study of marine sediments. Piston core samples are usually longer, less disturbed and more complete than those from gravity corers.

The main advantages of a Giant/Jumbo Piston Corer over a Gravity Corer are the longer and less disturbed samples. The action of the piston reduces internal friction and prevents plugging. Cores up to 60m are possible in soft sediments and muds.

The system is lowered to the seabed, where the acoustic release mechanism triggers the final free fall penetration to obtain a core sample.
