Data Processing Notes: ---------------------- Transmissivity and fluorescence are nominal and unedited except that some records were removed in editing temperature and salinity. Transmissometer #1005DR was calibrated in March 2008, and drifted significantly but steadily until July 2009; then a sudden shift occurred, so that maximum values between September 2009 and July 2010 were very low, ~25%/m. In August 2010 a study was made of transmissivity that led to a decision to apply post-processing corrections to all cruises between March 2008 and June 2010. Transmissivity data from this cruise were corrected by multiplying the original values by a correction factor, which was based on assumptions that deep offshore transmissivity from a June 2009 cruise should be about 62%/m and that drift was linear with time between March 2008 and July 2009. The corrections produced reasonable results for all cruises in that time period. For details on the transmissometer post-processing see: Transmissometer_1005DR_Corrections.pdf These data should still be considered estimates. The dissolved oxygen data for this CTD were recalibrated in three steps. The first correction was applied to data from above 1400 dbar and to all of cast 0040. The second was applied to data below 1400 dbar from casts 0015 to 0038. The final correction was applied to all data. See 2009-003-proc.pdf for details. Dissolved Oxygen data below 1400 dbar are very noisy and are considered less reliable because of the noisy signal, the limitations in the calibration, and because it was impossible to fine-tune the configuration parameters to get the best possible deep data, so there may be some hysteresis. The Oxygen:Dissolved:CTD data should be considered: ± 0.4 ml/l from 0 to 200 dbar. ± 0.1 ml/l from 200 to 500 dbar. ±0.04 ml/l from 500 to 1500 dbar. ±0.2 ml/l below 1500 dbar.
