Summary of Field Work: |
We plan to collect 16 vibracores using Coastal Carolina University’s vibracore. The cores are 10 m in length and 4” diameter. The coring equipment will be operated by students and faculty advisors in cooperation with shipboard marine technicians, the captain, and crew. The instrument will be deployed from the A-frame and lowered to the seafloor. Once on the seafloor, the vibrating motors will be engaged, allowing the inner core-tube and liner to sink into the sediments. For recovery, the core-tube will first be pulled from the seafloor using the hydraulics built into the vibracore system (without the use of the winch). Once the core-tube has been released from the seafloor, the winch will be used to pull the entire system back to the surface and aboard the vessel. After each recovery, the core-tube liner, now filled with sediment, will be removed and divided into 1.5 m sections, labeled, capped, and stored on the vessel. A new liner will be inserted into the core-tube and the instrument will be prepared for re-deployment. |

Summary of Facility Requirements: |
The R/V Revelle is requested. We will work with the ship's crew to identify deployment and recovery options for the vibracore system. |
