 PI:              Cindy Lee
 of:              Stony Brook University, Stony Brook, NY (SUNY-SB)
 dataset:         CTD profiles; pres, temp, salinity, etc.
 dates:           8 April 2006 to 13 April 2006  (20060408-20060413) 
 location:        N: 43.418  S: 43.248  W: 7.779  E: 7.995 
 project/cruise:  Medflux/EN416
 platform:        R/V Endeavor
 
 
 Methodology
 
 Change history: YYMMDD
    060724: original CTD data files via email from Joan Fabres (SUNY SB); 
    070213: data prepared by Terry McKee (PO Dept., WHOI) 
            and added to database by Cyndy Chandler, OCB DMO
 
 PI-notes:
    sta  1: First cast of EN416, water for traps
    sta  3: First FGP Pressure cast of EN416, First day of cruise.
    sta 12: morning FGP cast 
 
 DMO Notes: Data were recovered from Seabird-processed .asc data files and are
    reported as 0.5 dbar pressure sorted profiles. CTD sensors corrected using 
    pre-cruise calibrations; only preliminary comparison has been done with 
    in-situ data, e.g. no post-cruise calibration work has been done. Station 19 
    data is from the uptrace portion of the cast.  Use with caution.
