This file describes the contents of the sail directory.
There are two files for each cruise.

N*SFCCHL.TXT : contain near-surface (-3m) chlorophyll values
               determined from samples taken periodically
               during the cruise. 

N*SAIL.TXT   : contains continuous temperature, salinity, and
               relative fluorescense measurements while underway
               from the flow-through system at -3m. Chlorophyll
               measurements (see N*SFCCHL.TXT) were used to
               calibrate the fluorescense channel to produce
               a continuous chlorophyll series.  

The subdirectory "PLOTS" contains contour plots for each
parameter for each cruise. These files are in Adobe portable
document format (PDF).
