Transmissivity: The data are nominal and unedited. The pressure sensor is considered ±1db The CTD salinity is 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. Due to limitations in the cell thermal mass correction, there is an inclination to low salinity values just above the thermocline and salinity tends to be high by up to 0.05psu just below the thermocline. In well-mixed waters that error can be seen to gradually reduce until the CTD is about 50db below the thermocline. No editing was applied in such cases, since it would require interpolating over a large distance. Dissolved oxygen is considered: • ±1ml/L from 0db to 150db • ±0.3 from 150 to 500db • ±0.1 below 500db • unreliable below 1200db *CALIBRATION $TABLE: CORRECTED CHANNELS !
