The voyage took place between January 25 and March 2, 2023, departing from Henderson (WA) and returning to Hobart. Standard Underway data is continuously recorded, consisting of: (1) Navigation data (NAV): Latitude, Longitude, Speed, Heading, Course Over Ground, Gyros, and Doppler Log (dual GPS instrument). (2) Thermosalinograph (TSG): Water Salinity, Flow-Rate, Temperature, Fluorescence, pCO2 and Optode/Oxygen. (3) Atmospheric (MET): Humidity, Wind Speed and Direction (vane and ultrasonic), Radiometer/Sea Surface Temperature, Pyranometer/Solar Radiation, Photosynthetically Active Radiation (PAR), Air Temperature, Air Pressure, Rain, Ozone and Trace Gases (port and starboard instruments). The quality-controlled RV Investigator underway meteorological and SST data are supplied to the IMOS AODN and other global data repositories and distributors, and made available for satellite SST validation by the Australian Bureau of Meteorology (BoM). Near real-time, unprocessed data are available via the link "Visualisation tool for Underway Data." This dataset has been processed (quality-controlled), and archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC). Data are available at time intervals of 5 sec (NetCDF format), 5 sec, 10 sec, 1 min and 5 min (ASCII format). Note: not all variables are quality controlled; please check for existing QC flags in the datasets. Additional information regarding this dataset is contained in the Voyage Summary and/or the Data Processing Reports for this voyage. {"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 10-second Underway data (CSV) documentDigital Download the 10-second Underway data (CSV format) HTML 5 minute Underway data (CSV) documentDigital Download the 5 minute Underway data (CSV format) HTML 5 second Underway data (netCDF) documentDigital Download the 5 second Underway data (netCDF format) 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 1 minute Underway data (CSV) documentDigital Download the 1 minute Underway data (CSV format) HTML 5 second Underway data (CSV) documentDigital Download the 5 second Underway data (CSV format) HTML TSG Calibration Data (CSV) documentDigital Download the TSG Calibration Data (CSV format) HTML Investigator Survey documentDigital Link to RV Investigator Survey Information, including voyage plans and summaries HTML Underway Visualisation Tool documentDigital Link to visualisation tool for Near Real-Time Underway Data HTML Marine National Facility documentDigital Link to the Marine National Facility Homepage HTML Unnamed resource documentDigital License Graphic PNG
