The dissolved oxygen data for this CTD were recalibrated in three steps. The first correction was applied to data from above 1400db and to all of cast #40. The second was applied to data below 1400db from casts #15-38. The final correction was applied to all data. See 2009-03-proc.doc for details. Dissolved Oxygen data below 1400db 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 DO data should be considered: • ±0.4ml/l from 0- 200db • ±0.1ml/l below 200- 500db • ±0.04ml/l from 500-1500db • ±0.2ml/l below 1500db ********************************************************************************* 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 how the correction factor was derived see: OSD_Data_Archive:\Cruise_Data\DOCUMENTS\Transmissometer 1005DR Corrections.doc These data should be considered estimates. ********************************************************************************* *CALIBRATION $TABLE: CORRECTED CHANNELS !
