compare_oxy

 COMPARE_OXY -  Diagnostics plots to compare CTD and samples dissolved oxygen values.

 CTD Calibration toolbox.

 USAGE:
 compare_cond(cruiseid);

INPUT: cruiseid: Cruise identification name.
   
 OUTPUT: A series of plots to compare CTD and bottle samples dissolved oxygen values 
          
 DESCRIPTION: This function uses the summary conductivity calibration file created by  
 make_oxy_sum and do a series of diagnostics plots to compare CTD and
 bottle samples dissolved oxygen values to evaluate the quality of the data
 that we are coleecting, as well, any potential problems with
 niskin/sample bottles or sensors.
