 dates:           2004 - 2005
 location:        Sargasso Sea 
 project/cruise:  EDDIES/WB0409 2004 Transect 1 (EDT1)
                  EDDIES/WB0413 2004 Transect 2 (EDT2)
                  EDDIES/WB0506 2005 Transect 1 (EDT3)
                  EDDIES/WB0508 2005 Transect 2 (EDT4)

 Change history: YYMMDD
    070308: downloaded original data from EDDIES data Web site 
            (200609 DM FINAL_corrected.xls);
            prepared for OCB database by Nancy Copley, OCB DMO
    070313: added to OCB database by Cyndy Chandler, OCB DMO
            event number is from cruise event log
    070405: per Jason Perl, units for all pigment concentrations  
            changed from microgram/kilogram to microgram/liter 
 
 PI note: 080317: Recalibrated data are expected from NASA during the second half of 2008.
