Paper Abstract

Biofouling has been a serious question in the stability of optical measurements in the ocean, particularly in moored and drifting buoy applications. Many investigators coat optical surfaces with various compounds to reduce the amount of fouling; to our knowledge, however, there are no objective, in-situ comparative testing of these compounds to evaluate their effectiveness with respect to optical stability relative to untreated controls. We have tested a wide range of compounds at in-situ locations in Halifax Harbor and in the Adriatic Sea on passive optical sensors. Compounds tested include a variety of TBT formulations, antifungal agents. and low-friction silicone-based compounds; time-scales of up to four months were evaluated. The results of these experiments are discussed.
