Vibracore

---

Vibracores (as the name suggests) advance a lined core barrel into the sediment using vibration. They are primarily used to sample sandy sediments that can’t be cored with gravity based coring devices. SEASAM has an Ocean Instruments RIC5500 pneumatic vibracore capable of operating in up to 100m of water, obtaining 8 mm diameter cores up to 6 m in length.

We have run a RIC5500 off of a small boat during expeditions. We maintain a generator and cabled winch for operations outside of standard ARF stern deployment.

We also have an Alpine vibracore available (great for shallow water depths), and the infrastructure to use it in the Salish Sea area.
