Maintenance and Update Frequency: asNeeded Statement: Original field data. NOTE: on 08/02/2022 the linked data were updated with reprocessed data that corrected an error in the sample-to-sensor lag time. For more details please refer to the Processing Report. Data processing and quality control by the Marine National Facility Data Acquisition and Processing Group (DAP). Data were processed using the new CapPro system (version 2.11). Data archived by the CSIRO NCMI Information and Data Centre. Credit CTD data processed by Stephanie Zeliadt (CSIRO NCMI). This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2020_V08, titled: "SOLACE - Southern Ocean Large Areal Carbon Export: quantifying carbon sequestration in subpolar and polar waters". The voyage took place between 4th December 2020 and 15th January 2021, departing from Hobart (TAS) and arriving in Hobart (TAS). Data for 86 deployments were acquired using the Sea-Bird SBE911 CTD 24, fitted with 36 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 a single deployment grouping. The final calibration from the primary sensor had a standard deviation (SD) of 0.0014177 PSU, well within our target of ‘better than 0.002 PSU’. The standard product of 1 decibar binned averaged were produced using data from the primary sensors. The dissolved oxygen data calibration fit had a SD of 0.65769μM. The agreement between the CTD and bottle data was good. An Altimeter, PAR, Transmissometer, Fluorometer and two UVPs were also installed on the auxiliary A/D channels of the CTD. There were 86 deployments and of these, deployment 1 was a shallow water test run. Deployment 75 was aborted due to ...
