Transmissivity: The data are nominal and unedited. The pressure sensor is considered ±1db The CTD salinity is generally considered ±0.001psu when stopped. In motion the salinity is considered ±0.005psu except in areas of rapid temperature change where the salinity has been edited heavily and should be considered ±0.1psu. Further errors due to calibration drift may also be present. Salinity has not been recalibrated because of doubts about the analysis, but the drift appears to be < ±0.003. Based on bottles from just 6 casts, the SBE dissolved oxygen data in the CTD files appear to be within: • ±0.3ml/l from 0 - 200m • ±0.05ml/l below 200m *CALIBRATION $TABLE: CORRECTED CHANNELS !
