The voyage took place from Hobart (TAS) to Hobart between September 11 and October 8, 2018. Data for 25 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 0.0012361 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 0.7997µM. The agreement between the CTD and bottle data was good. A Wetlabs CSTAR Transmissometer, Chelsea Aquatracka III Fluorometer, Wetlabs CDOM Fluorometer, and PAR sensor were also installed on the auxiliary A/D channels of the CTD. The collected data were subsequently processed and archived within the CSIRO Oceans and Atmosphere (O&A) 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. {"type": "Polygon", "coordinates": [[[140.754, -47.179], [154.639, -47.179], [154.639, -34.298], [140.754, -34.298], [140.754, -47.179]]]} 140.754 154.639 -47.179 -34.298 CTD Data .nc documentDigital Download the CTD Data (NetCDF format) HTML CTD Data .csv documentDigital Download the CTD Data (CSV format) HTML CTD Data .mat documentDigital Download the CTD Data (Matlab format) HTML Data Trawler documentDigital Link to Data Available for this Voyage via the Data Trawler HTML Investigator Surveys documentDigital Link to RV Investigator Survey Information, including voyage plans and summaries HTML Data Processing Report documentDigital Download the Data Processing Report (PDF format) HTML Marine National Facility documentDigital Link to the Marine National Facility Homepage HTML Data Licensing documentDigital Link to Data License / Attribution statements HTML Unnamed resource documentDigital License Graphic PNG
