Dataset: Niskin bottle and CTD data; nutrients, oxygen, DIC, POC, PON from R/V Weatherbird II WB0409, WB0413, WB0506, WB0508 cruises in the Sargasso Sea, 2004-2005 (EDDIES project)

 PI:              Nick Bates
 of:              Bermuda Biological Station for Research (BBSR)
 dataset:         Niskin bottle and CTD data; nutrients, oxygen, DIC, POC, PON
 platform:        R/V Weatherbird II
 
 Methodology: see Chapter 3: CTD & Related Measurements in U.S. JGOFS BATS

 OCB DMO Note: Longitude changed to negative values indicating West;
    depth_n estimated, surface at 1 meter;  Niskin_id (90409##nn) split 
    into sta '##' and Nis bottle number 'nn'.  HPLC from original datafile 
    not included because newer HPLC pigment data are already in database; 
    all data are from primary sensors; event number is taken from cruise 
    event log, and DMO added bot numbers to support data integration
 
 PI note: All bottle fires included; most include sampling data. Level 
    of Detection (LOD) not imposed for nutrient data. Typical methodology 
    suggests LOD's of ~ 0.03 umol/kg for NO3+NO2 and SRP. No sample, 
    Missing or bad data set to nd. Fluometric analysis for chl_a and 
    Phaeo using 500ml sample were performed by BIOS BBOP lab.
    
    Analysis Note: files listing SiO4 data from the sample rerun:
    WB Silicate reruns

 
 Caution:  this data set is considered final, but it is unknown whether 
    the CTD data have had any post-cruise calibrations applied.
