The increased penetration depth of the Piston Corer has made it one of the basic tools used in the study of marine sediments.  Piston core samples are usually longer, less disturbed and more complete than those from gravity corers. 

The main advantage of a Piston Corer over the Gravity Corer is the greater length of core obtained.  The action of the piston reduces internal friction and prevents plugging.  Cores over 18m are possible in soft sediments and muds.

For further information on OSIL's range of Sediment Corers please read our Sediment Sampling Brochure.
