DATA PROCESSING AND PRESENTATION 



3. 1 



Survey Trackline Reco ns t ruction 



Survey tracklines vie re reconstructed from the "Autotape" 

 ranyes and transit angles logged at each position "fix." 

 These values, together with the grid coordinates of the 

 responder and theodolite locations, were input into OSI's DEC 

 PDP 11/44 computer system which calculated the X and Y 

 coordinates for each recorded position. During calculation 

 of the vessel positions, geometric consideration of responder 

 elevations, interrogator antenna height, X and Y corrections 

 for sensor layback and offset (relative to the "Autotape" 

 antenna), and range calibration data were also input to yield 

 the most precise computation possible.

Tide Level Data 



Half-hour water elevations taken from the continuous tide 

 level chart recordings collected during the survey were 

 referenced to the MLW datum and are presented graphically in 

 Figure 3 and in tabular form in Appendix II. 



3.3 



In Situ Current, Temperature, and Salinity Data 



The recorded current, temperature, and salinity data were 

 translated employing an Endeco Type 250 data translator and 

 input into OSI's in-house computer system for processing. 

 Each data set was then corrected for the individual 

 instruiTient calibration and computer plotted as time series 

 plots. Data from the 24 and 25 August deployments at Station
