 (5) BRIEF DESCRIPTION of DATA FILE:  1m vertical bin averages of 9 CTD casts, including
     uncalibrated OBS and uncalibrated chlorophyll a fluorescence, taken aboard the
     R/V El Mar on the Altamaha River during a spring tide on April 17, 1995.

 (6) KEYWORDS:  Altamaha, CTD, Spring

 (7) RESEARCH LOCATION:  The Altamaha river from AL+013.0 to AL+032.3 (2 digit river
     code + 4 digit code for distance from river mouth in km).

 (8) EXPERIMENTAL DESIGNS AND METHODS: Casts were taken with a SeaBird Electronics CTD25
     (S/N 94).  The collected data's downcasts were processed using standard SeaBird
     software to produce the 1m vertical bin averages.

 (9) NOTES AND COMMENTS:  Each cast has a header that contains information in the  
     following order: cast number,station location, date, time (EST), max water 
     depth (M), latitude (N in degrees and minutes), and 
     longitude (W in degrees and minutes).  Estimated predicted tidal height at 
     station AL+010: High Water at 1050 EST, Low Water at 1755 EST.

                  Salinity=PSS-78
                  Sigma-t=p(s,t,O)-1000
     Both salinity and sigma-t were computed by the SeaBird software program.  The 
     formulas used were obtained from "Algorithms for Computation of Fundamental    
     Properties of Seawater" by N.P. Fofonoff and R.C. Millard Jr.; Unesco technical
     papers in marine science #44, 1983.
