Exposure Site 



A site was desired where the test specimens would be exposed to 

 biological growth and subjected to the strong tidal currents, high waves, 

 and rough sea conditions encountered during storms. Such a test site was 

 provided near the end of the 400-foot-long Point Mugu pier, which is located 

 at the head of the Mugu Submarine Canyon (Figure 3). 



The test panels were placed in a metal rack. The individual panels 

 were held separately and securely in place by four ceramic insulators (see 

 Figures 1 and 2). The ceramic insulators also served to prevent galvanic 

 corrosion, which is caused by the presence of an electrical circuit between 

 two dissimilar metals. The racks with the test specimens were lowered from 

 the pier and submerged approximately 15 feet below high tide level. At high 

 tide the water depth is about 20 feet at the exposure site.
