Three specimens of the horse mussel. Mod i o lus 

 fornicatus, were found On the hull. Approximately 2 

 tests of barnacles, Balanus t int innabulum cal if o rnicus , 

 were cemented to the bulkheads of the rear ballast tank 

 inside the hull. These were the only barnacles observed 

 in this zone. 



MOORING TACKLE 



Portions of the tackle used in the deep mooring of the 



hull, consisting of a pile of l^-inch chain (fig. 6) and some 



heavy polypropylene line (fig. 7) were also available for 



inspection. The chain was almost entirely covered with 



a foliaceous red algae. One large jingle, Pododesmus 



mac roschi sma was observed. Also present were colonies 



of the small tube worms, Phyl lochaetopt e rus prolifica.

 A loose scab of rust, perhaps i^ -inch thick, covered the 



links . 



The line, which seemed to be in excellent condition 

 externally was also fouled by red algae, but not as heavily 

 as the chain. The tube worms, P- prolifica, present 

 on the line seem to have taken hold in the creases of the 

 lays. This is, in fact, where most of the fouling had 

 settled. Many small horse mussels, M. f o rnicatus , 

 were also found in the lays of the line (fig. 7). Scattered 

 colonies of unidentified bryozoans and the base plates of 

 barnacles were observed. There was no evidence of 

 marine borers on the line. With the exception of the algae, 

 the line was more heavily fouled than the chain.
