Standard seabird processing steps were used. 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 78 out of 95 with a standard deviation of 0.02 in the residuals. Coefficients used: Slope: 1.3392, Bias 0.0035. Alignment of -3 seconds was used. Frequent single dropouts in fluorescence to 0 have been fixed by setting to neighbor value. Oxygen Calibration: A lag of -6 seconds was applied to oxygen voltage in Seabird data processing step Align. The oxygen sensor membrane had attachment problems during cruise due to factory issues. Numerous calibrations were necessary. For the 50 casts, 19 calibrations were applied. A remaining pressure dependent shape in the residual between water sample and CTD oxygen was removed by subtracting a mean curve. Parts of the mean curve were found by fitting sections of data from discreet pressure ranges. The parts were then stitched together via spline interpolation to create a full profile mean curve. See Table 3., page 21 in report "Physical, chemical and zooplankton data from the Canada Basin and Canadian Arctic Archipelago, July 29 to September 1, 2005." cited below. Problems with data: - Spikes were more frequent than usual perhaps due to a problem in the electrical connection. Spikes in temperature, conductivity and oxygen have been linearly interpolated over. - In addition to drift, the oxygen voltage very frequently dropped to zero, although only for short periods. The zero voltage was linearly interpolated over. References: 1.
