Brief description
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 technical difficulties and the data was not processed. During deployment 33, a significant blockage was visible in the primary sensor downcast data and it is recommended to use the secondary sensor data for this cast.
The collected data were subsequently processed and archived within the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC) in Hobart. Additional information regarding this dataset may be contained in the Voyage Summary and the CTD Data Processing Report.
