Altimeter added on Cast 15. Temperature was calibrated with the pre-cruise calibrations. Conductivity, Oxygen and Fluorescence were calibrated to water samples. Salinity was recalculated using the corrected conductivity. Transmissometer and Altimeter are not calibrated. Fluorometer notes: Calibration with bottle data performed using bottle chlorophyll values between 0.025 and 0.6 mg/m3. The number of observations used were 75 out of 93 with a standard deviation of 0.02 in the residuals. Coefficients used: Slope: 1.4585, Bias -0.0026. Downcast CTD Fluorometer with bad values replaced with good upcast values for casts 19, 20 30, 34, 37 and 40. Remaining bad data replaced with -99. Oxygen Calibration: Casts 1 to 50 (full cruise) oxygen was calculated from oxygen voltage using the Seabird Owens-Millard algorithm using coefficients: boc: 0, tau: 0, tcor: 0.0015, pcor: 1.3500e-004, voffset: -0.4716, soc: 0.3753. A lag of -6 seconds was applied to oxygen voltage in Seabird data processing step Align. References: 1. McLaughlin, F., Carmack, E.C., Zimmermann.
