The precision of the SBE dissolved oxygen channel is difficult to estimate because the comparison with bottles was very noisy, but roughly, the DO should be considered: • ±0.6ml/l from 0-100db • ±0.2ml/l from 100-500db • ±0.08ml/l below 400db ********************************************************************************** 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 correction factor 2.44, which was based on the assumption that deep offshore transmissivity should be about 62%/m. For details on the transmissometer post-processing see: OSD_Data_Archive:\Cruise_Data\DOCUMENTS\Transmissometer 1005DR Corrections.doc These data should still be considered nominal. ********************************************************************************** For details on the processing see processing report: 2010-12-proc.doc. *CALIBRATION $TABLE: CORRECTED CHANNELS !
