2. Tabulated Sunmia-rles . The tabulated summaries of PART B do 

 not convey such detailed information. They are useful, however, in 

 giving reliable, over-all data in convenient, tabulated form. The data 

 cover upward of 530 test board locations at approximately l60 different 

 harbors, mainly on the U. S. Atlantic coast, the Caribbean, and the Texas 

 coast; some South American harbors (Venezuela and Brazil); the Mediterranean; 

 the U. S. Pacific coast from Adak, Alaska, to the Canal .Zone; some Pacific 

 islands, Australia, and New Zealand. 



5. Other Comprehensive Narrative Summaries . Further suimnaries 

 of marine borer research results in many parts of the world will be found 

 in Harbor Reports on Marine Borer Activity , a publication of the Bureau 

 of Yards and Docks. 



A1.07 Applications of Continuous Eesearch Program 



Some practical applications of the marine borer research program 

 now under way exe summarized below. 



1. Test board data have proved to be extremely valuable to 

 writers of specifications for wharf construction in various Atlantic 

 and Pacific harbors. 



2. These data have been very useful in studying the fouling of 

 intake tunnels, service pipe lines on government vessels, and ships' 

 bottoms . 



5. In harbors where hydrographic conditions and associated 

 organisms are favorable for borers, test board data serve to warn the 

 builders of marine installations that structural materials must be 

 selected with great care. 



h. Continuous research data have proved to be of inestimable 

 value in the maintenance of marine structures . Thus a sudden borer 

 invasion, or the probability of an increase in their destructiveness, 

 can be quickly determined by studying recent test panels or traps. 

 Heavy losses may be averted by making thorough inspections of. marine 

 structures at intervals; test board data should be utilized as warning 

 signails between such inspections. 



5. in a given sti*ucture, the mere presence of marine borers of 

 some kind does not necessarily prove that the structure is headed for 

 complete destruction. More significant information is required, that 

 la, a complete understanding of the true relationship of the borers 

 present to borers in general. This can only be achieved by identifying 

 and classifying the borers in the structure under investigation.
