CalCOFI 9707JD CTD Data Processing Notes 2021

This cruise looks pretty clean with only a single set of T, C, & O2 sensor set.
Transmissometer, fluorometer, PAR, Altimeter were also deployed. No sensor failures
or changes were noted. 
Note: these raw ctd files were processed in a WindowsXP-DOS virtual pc under Windows
using DOS-based Seasoft Data Processing Software. Once the cnvs were generated one-by-one,
these files were processed using the Windows SBE Data Processing modules v7.23. An .xmlcon
file was created from the .con by transferring the coefficients into the newer version.
Since there were no obvious changes to the .con files from cast 001 to 066. A single
.xmlcon file was used in Derive to generate the module-corrected sensor data.


There were a few corrections:

Cast 001: Line.Sta was changed from 93.26.7 to 93.3 26.7 for proper parsing
Cast 050: Line.Sta was changed from 83.40.6 to 83.3 40.6 for proper parsing
Cast 011U: salinity data from 49-51m was nulled since there was a spike. Use
  downcast data if needed since they are clean.
