occurrence of a value that differed from the previous value by more than 

 0.3 fps was attributed to an electronically induced spike and was edited to 

 the average of the previous and succeeding values . 

 Output 



70. The output files, CM*S , CM*M, and CM*B represent current meter sta- 

 tion * at surface, middepth, and bottom, respectively, where * indicates 

 the station number. They are unformatted, sequential access files of record 

 length 5. Each record contains five data words: time, velocity, direction, 

 temperature, and conductivity. The first 21 records are character strings 

 that are to be concatenated into seven 60-character information strings. A 

 typical open statement for a current file is as follows: 



OPEN (UNIT=1,FILE=CM1S. DAT' , F0RM=UNF0RMATTED ' , STATUS= ' OLD ' , REC0RDLENGTH=5 ) 



71. Various plots of the current velocity and direction time series 

 were produced. Shaded rose plots of entire time series (Appendix E) show mean 

 velocity and percent occurrence in each of 20 degree sectors. These plots are 

 useful in displaying dominant directions and velocities associated with each 

 site. Separate velocity and direction time series illustrate the trends of 

 each data set and allow quick verification of data quality (Appendixes F 



and G) . 



Current Profile Data 



72. The current profile data required no analysis since they were read 

 directly in engineering units and entered as such into a file. Direction and 

 velocity were subjectively averaged during observation of the analog output 

 meters . 



73. The entire profile data set is listed in tabular form in 

 Appendix B. A sample plot of profile data from Range 5 is provided in 

 Figure 8 as a vector time series for each depth. Figure 9 is a sample of di- 

 rection and velocity time series of Station 5A for all three depths.
