Credit The data were processed by Peter Hughes, Julie Janssens and Harris Anderson (CSIRO NCMI). Credit The MNF must be acknowledged in all outputs derived from Data and/or Samples collected by, or with support from, the MNF. Acknowledge the MNF in outputs with the statement: “We acknowledge the use of the CSIRO Marine National Facility (https://ror.org/01mae9353 ) in undertaking this research.” Acknowledgment and citations should be in all forms of publication including presentations (where the acknowledgement should be on the closing slide), journals, books, reports and related research outputs. This record describes Hydrology (HYD) data collected 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." The voyage took place between June 5, 2023 and June 18, 2023 (AEST), departing from Hobart and returning to Hobart. Hydrology samples were collected from Niskin bottles sampled at various depths during Conductivity-Temperature-Depth (CTD) deployments. Parameters analysed were salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite and ammonium. 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.
