This dataset has been processed and is archived within the CSIRO Marine and Atmospheric Research Data Centre in Hobart. Additional information regarding this dataset is contained in the voyage plan and voyage summary. The standard Underway (=continuously recorded) dataset from a research voyage includes Navigation (NAV), Sounder (PDR), Thermosalinograph (TSG) and Meteorological (MET) data. NAV data includes GPS (Global Positioning System) measurements of latitude, longitude, ship's direction and speed. MET data may include atmospheric temperature, humidity and pressure, wind speed and direction, and incident radiation intensity. Data are recorded at 10 second intervals.
