The voyage took place between June 5 and June 18, 2023 departing from Hobart (TAS) and returning to Hobart.\nData for 10 CTD deployments were acquired using the Sea\u2010Bird SBE9+V2 CTD unit #24 (S/N 1332), fitted with 36 twelve\u2010litre bottles on the rosette sampler. Sea\u2010Bird\u2010supplied calibration factors were used to compute the pressures and preliminary conductivity values. CSIRO\u2010supplied calibrations were applied to the temperature data. The data were subjected to automated QC to remove spikes and out\u2010of\u2010range values. \nThe final conductivity calibration was based on a single deployment grouping. The final calibration from the secondary sensor had a standard deviation (SD) of 0.0010067 PSU, well within our target of \u2018better than 0.002 PSU\u2019. The standard product of 1\u2010decibar binned averages were produced using data from the secondary sensors.\nThe dissolved oxygen data calibration fit had a SD of 0.92376 \u03bcM. The agreement between the CTD and bottle data was good.\nThe 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.", "num_resources": 10, "num_tags": 0, "organization": {"id":
