Completeness and Data Quality:

These notes relate to the production of quality controlled, calibrated CTD data from RV Investigator voyage IN2019_V06 Leg 1, from 19 Oct 2019 – 11 Nov 2019. Data for 96 deployments were acquired using the Sea-Bird SBE911 CTD #24, fitted with 24 twelve litre bottles on the rosette sampler. Sea-Bird-supplied calibration factors were used to compute the pressures and preliminary conductivity values. CSIRO-supplied calibrations were applied to the temperature data. The data were subjected to automated QC to remove spikes and out-of-range values. The final conductivity calibration was based on multiple deployment groupings. The deployments were grouped by changes in temperature or conductivity sensor. The final calibrations from the secondary sensor had a standard deviation (SD) of 0.0030308 and 0.0035894 PSU, outside our target of ‘better than 0.002 PSU’. The standard product of 1 decibar binned averaged were produced using data from the secondary sensors. The dissolved oxygen data calibration fit had a SD of 0.89666 µM. The agreement between the CTD and bottle data was good. A Biospherical PAR, Tritech Altimeter, C-Star Transmissometer, Seapoint Nephelometer, WET Labs ECO Scattering, and WET Labs ECO Chlorophyll sensor, were also installed on the auxiliary A/D channels of the CTD. The rosette was also fitted with 3 RBRconcerto³ CTD|ODO sensors measuring temperature, conductivity and oxygen.
