This record describes Hydrology (HYD) data collected from the Marine National Facility (MNF) RV Investigator voyage IN2025_V02, titled: "Multiyear: Integrated Marine Observing System (IMOS) Southern Ocean Time Series (SOTS) Strategic Partnership." The voyage took place between March 26, 2025 and April 14, 2025 (AEST), departing from Hobart and returning to Hobart. Water samples collected during the voyage were analysed in the ship’s hydrochemistry laboratory for nutrients, dissolved oxygen, and salinity. No significant sample collection, analysis, or data processing issues were encountered for reporting. Five nutrients were determined: silicate, phosphate, nitrate + nitrite, nitrite and ammonium using a Seal AA3 autoanalyser. Certified reference materials for nutrients in seawater (RMNS) were within certified expanded uncertainty. Missing and suspect hydrology samples are listed in Appendix, Missing or Suspect Nutrient Data. For more information please refer to the Data Processing Report linked below. This dataset has been processed (quality-controlled), and archived at the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC) in Hobart. Additional information regarding this dataset is contained in the Voyage Report and Data Processing Report.
