CTD #1091 was used for events #1-139 and the data quality looked good. CTD #1123 was used for events #149-214 and data quality was lower with unstable features that were likely due to intermittent flow rate variability. Oxygen:Dissolved, Conductivity and Fluorescence:URU:Seapoint data are nominal and unedited except that some records were removed in editing temperature and salinity. The comparison of CTD salinity with bottle samples was limited to 5m and had a lot of scatter, but median differences suggest that calibration of sensors used on both CTDs was reasonably good. The comparison of dissolved oxygen was limited to 5m where DO values were all high. No recalibration was applied due to the limitations of the comparison. This was the first use of this equipment since the sensors were serviced at the factory, so little calibration drift is expected in salinity, but dissolved oxygen is likely reading slightly low. The fluorometer used during events #149 to #214 malfunctioned, so that channel was removed.
