Fundamental data concerning the occurrence and distribution of marine borers and fouling organisms at twenty five world wide locations has been assembled. Information obtained, though insufficient to establish conclusively seasonal and biogeographic trends for given species, is invaluable as a starting point for additional, more frequent panel exposures in selected foreign and domestic localities in order to more clearly define the salient parameters of borer and fouling problems. Adequate data were obtained to identify twenty two species of marine borers, the various kinds of macro-fouling present, and to demonstrate the value of considering establishing a more closely defined exposure program at foreign locations. Sufficient undamaged specimens of marine borers were removed from the wood test panels for the taxonomic studies carried out by Dr. Ruth Turner, Harvard University, Cambridge, Massachusetts. Results of her studies were published in 1966 as the monograph, A Survey and Illustrated Catalogue of the Teredinidae Mollusca Bivalvia AD-630 696. Studies to explore the thermal effects on control of fouling were conducted and soon discontinued in 1960 due to defective material. Twelve electrical conductor cables were simultaneously exposed to both water and mud at three locations Daytona Beach, Florida Duxbury, Massachusetts and Wrightsville Beach, North Carolina for four to nineteen weeks. Macro-fouling was present in the water exposure area but no damage to the cables was observed. Microbial colonization was apparent on six of the twelve cable samples subjected to the mud exposure.
