Processing description

 
 Change history: YYMMDD
   061215: original data received from Susan Brown (UH Manoa);
   070129: added to OCB database by Cyndy Chandler, OCB DMO, (cchandler@whoi.edu)
   070328: update metadata from new version of cruise event log
   070503: data is now considered final following PI review
 
 OCB DMO Note: event, date, time, lon, lat and ev_type taken from event logs
 
 PI note: 
    all biomass reported in micrograms of Carbon per liter
