Overview

OBIC’s ocean-bottom instruments are based on the Scripps Institution of Oceanography LC2000 system, but have been, and are continuously being developed to perform more efficiently. The design allows the instrument to be broken down into components that are easily handled by two people, allowing for quick construction on deck prior to deployment.

The instruments are configured prior to deployment with the desired sample rate, gain and start time for recording. They are then sealed, mounted and secured in their chassis ready for deployment. Deployment is usually carried out by the ships’ crew, and involves using a pelican hook to release the instrument when the ship is in the correct location.

When the instrument is due to be recovered, an acoustic signal is sent to the seabed which instructs the instrument to jettison its anchor, allowing it to float to the surface. The untreated metal or concrete anchor is left on the seabed to degrade naturally.

OBIC’s current pool of equipment consists of over 50 instruments, and is constantly developing and evolving.
