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. Dissolved oxygen is considered: • ±1ml/L from 0db to 100db, • ±0.3 from 100 to the bottom PAR data are heavily corrupted but contains some useful data; they have not been edited. *CALIBRATION $TABLE: CORRECTED CHANNELS !
