There were 15 sponges ottoched to this tube. Water 

 absorption: 0.31%, 



There were 20 sponges ottoched to this tube. Water 

 absorption: 0.27%. 



There were 7 sponges ottoched to this tube. Water 

 obsorption: 0.02%. 



There were 5 sponges attached to the surface of the pipe. 

 Woter absorption: 0.26%. 



Remoined In excellent condition. A 3 ft long, I/8-In.- 

 diometer stainless steel welding rod wos inserted inside 

 the tubing to maintain rigidity in bio-rock. Water 

 obsorption: 2,24%, 



The wooden bolt piece exposed neor the sediment was 

 severely domoged, and the bolt piece exposed about 3 ft 

 above the sediment wos lightly domoged by borers. 



No surface crocking, remained flexible. Slight etch mark 

 coused by borer under wooden bait piece.

Shallow scrotch-like holes on the surface of insulation. 



Shallow scrotch-like holes on the surfoce of insulotlon. 



The entire surfoce of the insulation (except area under 

 coble clomp) is very irregulor. The thickness of the 

 insulotlon hos been reduced considerably. 



The surface oreo of the insulotlon wos roughened os o 

 result of marine onimols chewing ond nibbling on the 

 insulotlon. 



Very shallow borer holes on the surface of Insulation in 

 on oreo under the bait piece.
