This dataset contains the Voyage Data from Voyage 2 2021-22 collected during RSV Nuyina’s maiden voyage to Antarctica. This purpose of this voyage was a combination of commissioning trials, ice trials and a resupply voyage. The voyage departed Hobart and visited Davis station, Casey station, and the Vanderford Glacier before returning to Hobart. Throughout the voyage, operations related to ice trials and commissioning the science systems were conducted. As the instruments were commissioned, the data produced was included in the Voyage Dataset. It should be noted that many of the instruments were uncalibrated and, therefore, data recorded from these instruments may be erroneous. Oceanographic instruments that recorded data continuously throughout RSV Nuyina voyages include the Eco fluorometer, LISST-200X particle size analyser, Phytoflash flurometer, SeaFET pH sensor, SBE38 thermometer, SBE45 thermosalinograph and the SBE63 oxygen sensor. Oceanographic and mapping instruments that recorded data intermittently throughout the voyage include the ADCP38, ADCP150, EK80 hull system, EK80 dropkeel system, hydrophones dropkeel system, MS70 fisheries sonar, multibeam EM712, multibeam EM122, TOPAS sub-bottom profiler and the sound velocity sensor drop keel system. Meteorological instruments that record data continuously throughout the voyage include the WMT700 ultrasonic anemometers, UVB radiometer, CGR3 pyrgeometer, CMP3 global solar radiometer, CUV5 broadband UV radiometer, PQS1 photosynthetically active radiometer, CL31 Ceilometer, HMP155 air temperature and humidity sensor, PWD22 present weather and visibility sensor, PTB330 digital barometer and the all sky imager. Deployable instruments that recorded data throughout the voyage include the XBT, RBR concerto CTD, sound velocity profiler, NUTTS instruments and CTD instruments. Operational and positioning instruments that recorded data continuously through the voyage include the gyro compass, IPMS alarm system and webcams. Operational and positioning instruments that recorded data intermittently throughout the voyage include the winches, USBL, hydrophones hull system, draught sensor, speedlog, echosounder 50 kHz, echosounder 200 kHz and seapath380 systems. A list of the instruments used on the voyage is available in the file, "instrument_coverage_202122020.pdf" at the top level of the dataset.

This dataset contains the Voyage Data from voyage 202122050 undertaken by the RSV Nuyina between February 12th and March 27th 2022. The principal objectives of the voyage were to retrieve equipment and exchange personnel from Davis Station, and resupply Macquarie Island Station. The EK80 acoustic instruments, underway oceanographic instruments in the OceanPack system, the ice and wave radar, and meteorological instruments were all run during this voyage. Whole of voyage data from the RSV Nuyina underway instruments. Includes uncontaminated seawater, meteorological, and wave radar data interpolated to 1 minute measurements. Wherever possible, each parameter and its associated unit of measurement complies with the NetCDF Climate and Forecast (CF) Metadata Convention Standard Name Table (Version 29) - “voyage_202122050\underway_merger\netcdf\202122050_1min_all.nc
