Dataset: Bio-optical spar
Deployment: OC404-01

Please refer to descriptions for each cruise (deployment).

Calibration of instruments:
SBE-39s and SBE-37 were calibrated by SeaBird.

ECO-FLNTU Chl a and Optical Backscatter sensors were compared to the Oceanus CTD fluorometer during
comparison casts for each cruise.

Details of the UCSB Spar buoy deployed during EDDIES 2004 Survey 1.
    Due to the cancellation of the EDDIES Tracer 1 cruise, 
    the mooring was recovered at the end of Survey 1.

Calibration of instruments:
    SBE-39s and SBE-37 were calibrated by SeaBird.

    ECO-FLNTU Chl a and Optical Backscatter sensors were compared to the Oceanus 
CTD fluorometer during a comparison cast (oc404-4 053) during EDDIES 2004 
Survey 2.  Using the factory Chl a slope values, yielded Chl a values that 
were about twice that of the CTD fluorometer.  The comparison of the  
extracted Chl a and Phae a samples to the CTD fluorometer also showed the 
CTD fluorometer to be reading too low.  Therefore, the ECO-FLNTU readings
of all 3 profiles were matched with corrected CTD fluorometer values rather 
than factory calibrated CTD fluorometer values for oc404-4 053. There was 
significant differences in the Chl offset count for all 3 ECO-FLNTU sensors.  
The ECO-FL sensor failed to log during the comparison cast, so no adjustment 
to the factory calibration factors could be determined for this sensor.

    The Optical Backscatter channel of the ECO-FLNTU was too insensitive for 
optimal use in these clean waters.  

Therefore these data are not reported in the final report.
