Shallow-Water Test Site 



The shallow-water test site is located about 4 miles southwest of 

 Port Hueneme, California, in 120 feet of water. A Submersible Test Unit 

 (STU) was emplaced on the seafloor at this depth in December 1967 for 

 study of fouling and biodeterioration of material [9]. The concrete 

 test specimens were secured to the frame of the STU by Navy divers. 

 Periodically, test specimens were recovered by divers for inspection by 

 the project scientist. 



SEACON Test Site 



The SEACON Test Site [10] is located about 25 miles from Port 

 Hueneme, in the Santa Barbara Channel in 600 feet of water. The concrete 

 test specimens were lowered to the ocean floor at the SEACON site. 



Guantanamo Bay, Cuba 



Test specimens were exposed from a pier and also in a pump pit of a 

 desalinization plant located at Guantanamo Bay to determine what effect 

 toxic chemicals have on the attachment of fouling organisms to concrete 

 exposed in tropical waters.
