RV Investigator Voyage IN2026_V03 Hydrology Data

Oxygen Nutrients Sea Surface Salinity Sea Surface Temperature

This record describes Hydrology (HYD) data collected from the Marine National Facility (MNF) RV Investigator voyage IN2026_V03, titled: "SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania." The voyage took place between May 14, 2026 and May 22, 2026 (AEST), departing from Hobart and returning to Hobart.

For this voyage, CTD samples were collected and analysed for nutrients, dissolved oxygen, and salinity by the on-board Hydrochemistry team. Please refer to Hydrochemistry output section for more detail on sample types and analyses. Carbon and alkalinity samples were also collected at selected station by chief scientist, Dr. Elizabeth Shadwick to continue the time series established during previous voyage series, with these samples to be analysed on shore by the carbon team once the voyage concludes. 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.

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.
