| Summary: | Progress Code: completed Maintenance and Update Frequency: asNeeded Statement: Original field data. Data processing performed by the CSIRO O&A Data Acquisition and Processing group. Credit Underway data processing by the MNF Data Acquisition and Processing personnel. Credit This data was collected on the Marine National Facility (MNF) RV Investigator voyage IN2017_C01 Data processed by V. Dirita (CSIRO O&A) This record describes the Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator Voyage IN2017_C01, titled: "Great Australian Bight deep water geological and benthic ecology ". The voyage took place between 11 to 27 April 2017 departing from Hobart (TAS) and returning to Hobart (TAS). 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, Optode temperature and 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). Data are recorded at 5 second intervals. Near real-time data are available via the link "Visualisation tool for Underway Data." This dataset has been processed and archived within the CSIRO Oceans & Atmosphere (O&A) Information and Data Centre (IDC) in Hobart (TAS). Data are available at time intervals of 5 sec (NetCDF format), 10 sec and 5 min (ASCII format). Additional information regarding this dataset is contained in the Voyage Summary and/or the Data Processing Report for this voyage.
