There were problems with the calibration of the salinity. The salinometer malfunctioned and data run before and after repair look notably different. The later data has been used for recalibration, but there remain some doubts about it. The SBE dissolved oxygen sensor data were recalibrated differently for the earlier casts. Anoxic conditions during cast #1 may have affected the sensor up to cast #15. All casts from #15 onward were treated the same. The DO comparison with bottles had more scatter than usual. The SBE dissolved oxygen data in the CTD files should be considered • ±0.6ml/l from 0 - 200m • ±0.4ml/l from 200 – 400m • ±0.1ml/l from 400 - 1300m • data was removed from 1300m down since it is considered unreliable there *CALIBRATION $TABLE: CORRECTED CHANNELS !
