Processing description

  
 Change history: YYMMDD
    061228: original data received from Susan Brown (UH Manoa);
    070130: added to OCB database by Cyndy Chandler, OCB DMO, (cchandler@whoi.edu) 
            event, date, time and position data are from cruise event log
    070328: modify data set after QC review by Susan Brown (UH Manoa)
            see detailed list in DMO processing notes file
    070503: data is now considered final following PI review
    080213: added event_SFX from multi-ship event log
    
 PI note: 
    all pigment concentrations reported in nanograms per liter
