The fluorescence data have been removed because of instrumental problems. Based on comparison with bottle samples from around 10m during the upcast of well-mixed casts, the primary salinity appears to be within +/-0.002. Dissolved Oxygen data were recalibrated based on the results of cruise 2009-09 because there was no calibration sampling during this cruise. Since it is likely that some drift had occurred, these data must be considered less reliable than usual. The precision of the SBE Dissolved Oxygen channel for 2009-09 was considered to be, roughly: • ±0.4ml/l from 0- 150db • ±0.08ml/l from 150- 450db • ±0.04ml/l from 450-2000db ************************************************************************************* *CALIBRATION $TABLE: CORRECTED CHANNELS !
