From the above discussion on data processing and analysis, it is 

 apparent that in most cases the data gathered from site surveys should be 

 processed and analyzed by computer techniques. These techniques are more 

 rapid, accurate, convenient, and economical than manual techniques. Unfor- 

 tunately, since the requirements of each site survey differ, a step-by-step 

 procedure cannot be established for data processing and analysis that would 

 be applicable to all situations. The many computer programs written for 

 particular problems by the various researchers in the oceanographic field, 

 however, could be used in numerous cases, if they were available. Such pro- 

 grams can best be retrieved through the NODC (National Oceanographic Data 

 Center). The programs available from NODC are usually referenced in their 

 publications on summaries of computer programs, for example C-5. 54 



PRESENTATION OF RESULTS 



There are a number of forms in which data from site surveys can be 

 reported, such as, photographs, charts, graphs, tables, and logs. The choice 

 of which form to use depends on the quantity and parameter being reported. 

 In general, the selection should be governed by the question: "Which form 

 is most explicit in conveying the information?" A mosaic of photographs is 

 sometimes more useful than separate single shots. Charts, graphs, and tables 

 are constructed easily by computer methods from field data. Since each 

 problem may be unique, it is difficult to prescribe rules for presenting data 

 for all site survey parameters. The method of presenting data is thus dependent 

 mainly on one's own judgement. 



CONCLUSIONS 



The requirements for a given structure will govern the extent and 

 type of parameters to be assessed in the site survey. In general, however, 

 those parameters significant to the stability of the structure will have to be 

 assessed for all structures. A definite set of rules cannot be established that 

 would be applicable to site surveys for all structures. The data reduction and 

 analysis of parameters measured in these site surveys, however, are in general 

 best accomplished by computer techniques.
