 (5) BRIEF DESCRIPTION of DATA FILE:  1m vertical bin averages of 18 CTD casts,
     including OBS and uncalibrated chlorophyll a fluorescence, taken aboard the
     R/V Blue Fin on the Ogeechee River during a neap tide at both high and
     low water on October 15, 1995.

 (6) KEYWORDS:  Ogeechee, CTD, Neap

 (7) RESEARCH LOCATION:  The Ogeechee river from OG+000.3 to OG+032.4 (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 64).  After soaking at the surface for approximately 45 seconds, the CTD was  
     lowered to the bottom by a power winch and held there for approximately 45
     additional seconds before being raised to the surface.  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 OG+020: Low Water at 0730 EST, High Water at 1315 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.
