1999 Projects: Mooring improvements

Regulation of biofouling on moored optical sensors

Project lead/manager: Francisco Chavez
Project team: Peter Strutton

Biofouling is one of the most serious problems hindering the collection of unattended time-series measurements of biological and chemical oceanographic properties. This project focuses on the development of devices to mitigate biofouling on moored optical sensors. We have developed a shutter system for minimizing this problem on a moored spectroradiometer. The device proved effective on remote moorings in the equatorial Pacific, allowing us to collect reliable data there. It also has worked well enough in coastal deployments to allow the operation of a spectroradiometer for more than six months without requiring service. Prior to the use of this system, instrument servicing became necessary in less than two months. Under this project we will modify the system so it can be used on any commercially available spectroradiometer.
