RV Investigator Voyage IN2023_V04 (INIV) Data Products

This record describes the quality-controlled data products from the Marine National Facility (MNF) RV Investigator voyage IN2023_V04, titled "International nutrient inter-comparison study in the Southern Ocean: quantifying and identifying the causes of differences in dissolved inorganic nutrient datasets between global seagoing laboratories - Phase 2" (INIV). The voyage took place between June 5, 2023 and June 18, 2023 (AEST), departing from Hobart and returning to Hobart.\n\nFor further information please refer to the voyage documentation links.\n\nThe INIV data products have been created by the following teams:\n\n- CSIRO Data Acquisition and Processing: Acoustic Doppler Current Profiler (ADCP; 75, 150 KHz ), CTD, Lowered ADCP (LADCP), Underway (UWY), Infrared Sea Surface Temperature Autonomous Radiometer (ISAR)\n\n- CSIRO Hydrochemistry: Hydrochemistry (HYD)\n\n- CSIRO Geophysical Systems and Mapping: Fisheries Echosounder (EK80), Multibeam Echosounders (EM710, EM122), Sub-bottom Profiler (SBP120)\n\n- CSIRO Multiphase Atmospheric Chemistry: Scanning Mobility Particle Sizers (SMPS)\n\n- CSIRO Ocean Carbon Observations: pCO2\n\n- CSIRO Ocean Dynamics: Expendable Bathythermographs (XBTs)\n\n- ANSTO Atmospheric Research: Radon sensor\n\n- Voyage Science Participant Data: CRM nutrients, CTD nutrients\n\nThe datasets are curated by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC) in Hobart, with a permanent public archive at the CSIRO Data Access Portal (https://data.csiro.au/). All processed data from this voyage are also made publicly available through the MNF Data Trawler (in the related links).\n\nAll voyage documentation is available electronically to MNF support via the local network.
