This record describes the Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator Voyage IN2021_V01, titled "Quantifying krill abundance for krill monitoring and management off the Australian Antarctic Territory." The voyage took place between January 29 and March 24, 2021 departing from Hobart (TAS) and arriving in Hobart. Standard Underway data was 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). Near real-time data are available via the link "Visualisation tool for Underway Data." Except for gear trial voyages (or "event" voyages, identified by the survey name suffix "_eNN"), after each voyage the MNF will process (quality-control) the underway datasets. The processed data is archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC). Data is available at time intervals of 5 sec (NetCDF format), 5 sec, 10 sec, 1 min and 5 min (ASCII format). Additional information regarding processed datasets can be found in the Voyage Summary and/or the Data Processing Reports for this voyage.
