Fouling Characteristics: A variety of marine life inhabits the structure 

 including seaweed, barnacles, sea-squirts, starfish, crabs, seagulls, 

 ducks, and terns. 



Project Analysis: The New Tern Harbor log boom is rapidly reaching the end of 

 its operational life. The structure is waterlogged, eaten out, and 

 literally, falling apart. With the operator's attention, the log boom may 

 continue to survive for several more years, though its performance will 

 increasingly deteriorate. If the structure actually has as high a 

 transmission coefficient as the operator noted, the log boom has served 

 well. However, observing that the operator rated this FB as providing but 

 moderate performance in suppressing waves, it is assumed that its actual 

 effect on waves is much less than that reported.
