Sea-Bird-supplied calibration factors were used to compute the pressures, temperatures, and preliminary conductivity values. The data were subjected to automated QC to remove spikes and out-of-range values. The first CTD cast was a test and calibration cast to 1000 metres with all bottles fired at the bottom depth. Cast numbers 2 and 5 were shallow casts to perform SOTS mooring instrument calibrations. Cast number 3 was a deep cast to 4500 metres. Cast number 4 was a shallow cast to collect samples for the Petrou piggyback project. The final cast, number 6, was performed as a calibration for the new winch wire spooling and no samples were collected. The final conductivity calibration was based on a single deployment grouping. The final calibration from the secondary sensor had a standard deviation (SD) of 0.0012067 PSU, well within our target of ‘better than 0.002 PSU’. The standard product of 1-decibar binned averages were produced using data from the secondary sensors. The dissolved oxygen data calibration fit had a SD of 0.97891 μM. The agreement between the CTD and bottle data was good. A Wetlabs ECO FLBBRTD Chlorophyll-a and scattering sensor and a Chelsea AQUAtracka Chlorophyll-a sensor were also installed on the auxiliary A/D channels of the CTD. These data were logged in Seasave with calibration values applied. The only processing by CapPro was NaN filtering, and the resulting data are present in the average file. Standard data processing pipeline used: - SBEDataProcessing - Data Conversion to *.cnv - CNV to Scan file, conversion to *Ctd.nc - CapPro data processing to QC data, adjust T/C Lag, calibrate data with Hypro (bottle salinity and dissolved oxygen data), and bin calibrated data into profiles 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).

Full description

This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2023_V03, titled: "SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania" The voyage took place between May 11 and May 25, 2023 departing from Hobart (TAS) and returning to Hobart.

Data for 6 CTD deployments were acquired using the Sea-Bird SBE911 CTD unit #24, fitted with 36 twelve-litre bottles on the rosette sampler. Sea-Bird-supplied calibration factors were used to compute the pressures, temperatures, and preliminary conductivity values. The data were subjected to automated QC to remove spikes and out-of-range values.

The collected data were subsequently processed (quality-controlled), and archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC). Additional information regarding this dataset may be contained in the Voyage Summary and the CTD Data Processing Report.
