This record describes some Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator, which are not part of research datasets and have not been processed or quality-controlled. This includes data from most "Gear trials" voyages (identified by the survey name suffix "_eNN"). Underway data from these voyages are usually not processed unless requested. While RV Investigator is at sea, standard Underway data are 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). During the voyage, near real-time data are available from the MNF tool NRUD (Near Real-Time Underway Data) via the link "Visualisation tool for Underway Data" below. To request access after the voyage please contact the data custodian. The Underway data collected during research voyages (identified by the survey name suffix "_vNN") are processed and quality-controlled by the Marine National Facility (MNF). The processed datasets from these voyages are made available at time intervals of 5 sec (NetCDF format), 5 sec, 10 sec, 1 min and 5 min (ASCII/CSV format) through a voyage-specific metadata record. Additional information regarding processed datasets is available in the Voyage Summary and/or the Data Processing Reports linked to the relevant metadata records.
