 (5) BRIEF DESCRIPTION of DATA FILE:  1m vertical bin averages of 7 CTD casts,
     including uncalibrated OBS and uncalibrated chlorophyll a fluorescence, 
     taken aboard the R/V Blue Fin on the Ogeechee River on 02 February 1999.

 (6) KEYWORDS:  Ogeechee, CTD

 (7) RESEARCH LOCATION:  The Ogeechee River from OG+24.1 to OG+00.0 
     (2-character river code + 3-digit code for upstream distance from 
     river mouth in km).

 (8) EXPERIMENTAL DESIGNS AND METHODS: Casts were taken with a Sea-Bird 
     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 then raised to the surface.  The downcasts were processed 
     using standard Sea-Bird 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 (degrees and minutes N), and longitude 
     (degrees and minutes W).  Predicted tidal height at ~OG+05:  High Water 
     at 0912 EST, Low Water at 1545 EST.

(11) CALCULATIONS:
                   Salinity=PSS-78
                   Sigma-t=p(s,t,0)-1000
     Both salinity and sigma-t were computed by the Sea-Bird 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.
