There was no calibration sampling. There was only one previous cruise with calibration sampling (2024-006) that used CTD #0550 since those sensors were last serviced. Preliminary calibration sampling data from that cruise were available at the time this cruise was processed. The sensors were only used for part of 2024-006, so sampling was limited. Primary salinity was found to be low by about 0.0035psu, but some of that difference was likely due to incomplete flushing of Niskin bottles. No recalibration was applied to salinity since the evidence is weak, but the results suggest that salinity is within +/- 0.002psu. Dissolved oxygen values from 2024-006 looked consistently low by about 5.5%, so recalibration was applied to Oxygen:Dissolved:SBE. The temperature channels were in excellent agreement so both are likely well calibrated. The 2 salinity channels were within 0.002psu of each other.
