Data for 6 CTD deployments were acquired using the Sea-Bird SBE9+V2 CTD unit #23 (S/N 1312), 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. Seven CTD casts were performed in total. Casts #1-4 were performed in the original planned survey area, while casts #5-7 were performed at the alternative opportunistic science location The collected data were processed (quality-controlled), and subsequently 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 Data Processing Report. {"type": "Polygon", "coordinates": [[[64.024, -65.893], [147.512, -65.893], [147.512, -31.942], [64.024, -31.942], [64.024, -65.893]]]} 64.024 147.512 -65.893 -31.942 Data Licensing documentDigital Link to Data License / Attribution statements HTML Processing Report (PDF) documentDigital Download the Processing Report (PDF format) HTML Data Trawler documentDigital Link to Data available for this voyage via the Data Trawler HTML Plots for Processing Report (PNG) documentDigital Download plots associated with the Processing Report HTML Download the CTD Data (NetCDF Format) documentDigital Download the CTD Data (netCDF format) HTML Download the CTD Data (csv format) documentDigital Download the CTD Data (csv format) HTML Download the CTD Data (Matlab format) documentDigital Download the CTD Data (Matlab format) HTML Investigator Survey documentDigital Link to RV Investigator Survey Information, including voyage plans and summaries HTML Marine National Facility documentDigital Link to the Marine National Facility Homepage HTML Unnamed resource documentDigital License Graphic PNG
