This record describes Underway (UWY) data collected from the Marine National Facility RV Investigator Charter Voyage IN2015_C02 titled: Great Australian Bight (GAB) Deep water pelagic and benthic ecosystem study. The voyage took place between the 30th November to 22nd December 2015 departing Port Lincoln (SA) and arriving in Fremantle (WA). Standard Underway data is continuously recorded consisting of: (1) NAV: Navigation data: (dual GPS) Latitude, Longitude, Speed, Heading, course over ground, Gyros, and Doppler Log. (2) TSG: Thermosalinograph: Water Salinity, flow-rate, Temperature, Fluorescence, and pCO2. (3) MET: Atmospheric (port and starboard): Humidity, Wind speed and direction (vane and ultrasonic), Radiometer, Pyranometer, PAR, Air temperature, Air pressure, Rain, Ozone and Trace gases. Data are recorded at 5 second intervals. Near real-time data is available via the link below. This dataset has been processed and archived within the CSIRO Oceans & Atmosphere Data Centre in Hobart. Data is available in 5sec intervals in NetCDF, 10 sec and 5 min intervals in ascii csv format. Additional information regarding this dataset is contained in the cruise report for this voyage and/or the data processing report.

This record describes the End of Voyage (EOV) archive from the Marine National Facility (MNF) RV Investigator research voyage in2017_v01, titled "Interactions of the Totten Glacier with the Southern Ocean through multiple glacial cycles." The voyage took place from Hobart (TAS) to Hobart between January 14 and March 5, 2017. NOTE: the raw USBL data files lag 3 minutes behind the ship’s time due to an error with the NTP client. This only applies to the raw files directly logged by the USBL in the /usbl folder; and does not affect the TECHSAS recorded data, which is synchronized to the ship’s clock. For further information refer to the Voyage documentation links below. Instruments used and data collected include: Regular measurements: Acoustic Doppler Current Profiler (ADCP; 75, 150 KHz ), Fisheries echosounder (EK60, ME70), Multibeam Echosounder (EM710, EM122), Sub-bottom Profiler (SBP120), Gravimeter, GPS Positioning System, Doppler Velocity Log, Ultra Short BaseLine Underwater Positioning System (USBL), Starboard and Portside Radiometers, Nephelometer, Radon, Ozone and Oxygen sensors, Weather Radar, Greenhouse Gas Analysers (Aerodyne, Picarro), Air Pressure sensor, Wind Speed and Direction sensors, Thermosalinographs, CTD, Hydrochemistry, Expendable Bathythermographs (XBTs). Voyage-specific measurements: Aerosol Aerodynamic Particle sizer (APS), Aerosol Chemical Speciation Monitor (ACSM), ASD Field Spectroradiometer, Condensation Particle Counters (CPC), Cloud Condensation Nuclei counter (CCN, ccnc), Disdrometer, PAM Fluorometer, Light Detection and Ranging (LIDAR), Mercury Vapor Analyzer, Microtops, Multiangle Absorption Photometer (MAAP), Multi-Sensor Core Logger, pCO2, Proton-Transfer-Reaction mass spectrometry (PTR-MS), Scanning Mobility Particle Sizers (long SMPS, nano SMPS), Sea-ice, Seismic profiling, Sound Velocity Profiles (SVP), Ultra-Short Base Line (USBL; see NOTE below), Video, Volatile Organic Compounds (VOC) Gas Chromatograph (SEQ), Whale Observations. The archive for the IN2017_V01 EOV raw data is curated by the CSIRO Oceans and Atmosphere (O&A) Information and Data Centre (IDC) in Hobart, with a permanent archive at the CSIRO Data Access Portal (DAP, https://data.csiro.au/dap/), providing access to participants and processors of the data collected in the voyage. All voyage documentation is available electronically to MNF support via the local network. Access to voyage documentation for non-CSIRO participants can be made via DataLibrariansOAMNF@csiro.au.

This record describes the End of Voyage (EOV) archive from the Marine National Facility (MNF) RV Investigator Transit voyage in2016_t02, titled "Natural iron fertilisation of oceans around Australia: linking terrestrial dust and bushfires to marine biogeochemistry." The voyage took place from Hobart (TAS) to Sydney (NSW) between August 25 and August 29, 2016. Data collected during the voyage includes: (1) Acoustic Systems and Navigation: Acoustic Doppler Current Profiler (ADCP; 75, 150 KHz ), Fisheries echosounder EK60, Multibeam Echosounder - EM710, EM122, Sub-bottom Profiler - SBP120, GPS Positioning system, Doppler Velocity Log. (2) Underway: Starboard and portside Radiometers, Pyranometers, Radon, Oxygen, CTD, XBTs (Expendable Bathythermographs), Weather Radar, Greenhouse gas analysers - Aerodyne and Picarro, air pressure, wind speed and direction, PAR (Photosynthetically Active Radiation), Ozone, Thermosalinographs, (3) Voyage Specific: CPC: Condensation Particle Counters; CCN: Cloud Condensation Nuclei Counter; Gravity Meter; MAAP: Multiangle Absorption Photometer; SMPS: Scanning Mobility Particle Sizers; ISAR: Infrared Sea Surface Temperature Autonomous Radiometer. The EOV, XBT and Bridge logs were supplied and archived in pdf. ELOG files were generated as .csv and archived. All voyage documentation is available electronically to MNF support via the local network "global_docs." Access to voyage documentation for non-CSIRO participants can be made via DataLibrariansOAMNF@csiro.au. The archive for the IN2016_T02 EOV data is curated by the CSIRO Oceans and Atmosphere (O&A) Information and Data Centre (IDC) in Hobart, with a permanent archive at the CSIRO Data Access Portal (DAP, https://data.csiro.au/dap/), providing access to participants and processors of the data collected in the MNF RV Investigator IN2016_T02 voyage.
