MICROBIOLOGICAL FOULING AND ITS CONTROL IN COASTAL WATER AND THE DEEP OCEAN
The rates of microfouling film formation on various toxic and nontoxic substrates exposed to natural sea water have been measured using scanning electron microscopy. Exposure conditions for the test samples ranged from four days in shallow coastal water at Woods Hole to over 400 days at depths to 5000 meters in the Sargasso Sea. The results are discussed in terms of the surface energy of the substrate, and are applied to the problem of preventing the Savonius rotor speed sensor of oceanographic current meters from loss of calibration due to fouling. The conditions in terms of time and depth of exposure under which fouling preventative measures need to be undertaken are defined. Materials selection is discussed for a current meter to make near surface measurements under severe fouling conditions.
