Full description

This record describes Hydrology (HYD) data collected from the Marine National Facility (MNF) RV Investigator voyage IN2025_V04, titled:"Untangling the causes of change over 25 years in the southeast marine ecosystem - Voyage IV ." The voyage took place between May 27, 2025 and June 28, 2025 (AEST), departing from Hobart and returning to Hobart.

Water samples collected during CTD deployments were processed in the ship’s hydrochemistry laboratory and analysed for key parameters, including nutrients, dissolved oxygen, and salinity. Dissolved inorganic carbon and total alkalinity samples were also collected at selected stations to continue the time series established during previous voyages, with these samples to be analysed on shore by the CSIRO carbon team. Additionally, Thermosalinograph (TSG) samples were continuously collected throughout the voyage, with on-board measurements of their salinity used to calibrate the ship's underway system.
