Pressure values are considered +/-0.2db. There was insufficient information to estimate salinity accuracy, but based on very limited sampling during other 2021 cruises using this equipment, it is estimated to be within +/-0.005psu. Larger errors will be present due to minor misalignment of temperature and conductivity when vertical salinity gradients are high. No recalibration was applied to the CTD salinity. Oxygen:Dissolved:SBE values cannot be confirmed as there was no calibration sampling for dissolved oxygen. There was no 10m soak. Soaks at about 1m lasted long enough for the pump to come on, but the conductivity cell may not have had sufficient time to equilibrate and bubbles being released from the plumbing may lead to increased dissolved oxygen values in the top 10 to 15m.
