Abstract : Cooperative biofouling studies are being conducted off Maizuru, Yokosuka, and Sasebo, Japan, by the Japanese Maritime Self Defense Forces and the U.S. Naval Oceanographic Office. These studies will provide data which relate to the performance of underwater weapons systems of various kinds. Sampling is accomplished by exposing test panels for various periods of time from racks on the bottom in 9 to 10 meters of water. From the data collected during the first year of the program, June-July 1966 to June-July 1967, it appears that all three sites can be assigned to the same temperature faunal province. Biofouling on test panels at the three sites had a generally similar appearance, dominated by barnacles, erect bryozoans, and tubeworms. Organisms known to cause problems attach in great numbers and grow rapidly throughout most of the year. After 4 months, wooden panels were completely destroyed by Teredo navalis. The sampling program will continue at these and other sites. (Author)
