Abstract : The report presents partial results of a study of biofouling conducted offshore at Panama City, Florida. The data presented here were derived from a fouling station established 2 miles offshore in a water depth of 18 m. Two arrays of plastic floats were installed at this station, at depths of 4, 10, and 17 m. One array was unprotected; the test floats of the other were protected with an organotin compound. Floats were photographed, harvested, and new ones installed at intervals ranging from two weeks to one year. Data are presented on the nature of the accumulations on both arrays after field observation, and photographic and laboratory analyses. Differences in the accumulations are accounted for through the influences of temperature, salinity, and organotin. The influences of distance from shore, depth, and season upon temperature and salinity are also evaluated. The results from this station are only partially compared with results from the 25-mile station, on which a report has already been issued, and with the 11-mile station on which a report will be issued in the near future.
