CONCLUSIONS 



The computer program discussed here pre- 

 sents one approach to the data processing of 

 STD digital data logger tapes. There are un- 

 doubtedly many alternative techniques which 

 may do just as well. The system described above, 

 however, has the virtue of having been used 

 for nearly 2 years, and it is felt that this pro- 

 gram produces a set of data which most nearly 

 represents the signals generated by the STD 

 sensor package, in a form easily interpreted by 

 most of those who need to work with the data. 



The additional problems of relating these 

 data with independent measurements and of 

 eliminating random and systemic errors are 

 peculiar to individual instruments, cruises, per- 

 sonnel, and techniques, and almost always must 



be determined by the experimentor. The method 

 used on the EASTROPAC data was to take the 

 output of the program described here, compare 

 these data with the independent calibrations, 

 and then correct on the computer for any drift 

 or offset noted during the cruise. In addition, 

 the salinity trace is filtered to produce a profile 

 similar to that shown in figure 6.
