[ENTER INFORMATION FROM DAP DATA SUBMISSION FORM, SECTION DATA ACQUISITION -> DATA PROCESSING AND ANALYSES; EXAMPLE:] Nutrient samples were analysed using segmented flow SEAL AA3 and results are in µmol/L. In-house methods M1 V01, M2 V01, M3 V01, M4 V03 were used to analyse nutrients. Salinities were analysed using Guildline 8400B Autosal Lab salinometer and OSIL software, units are salinity units. Dissolved Oxygen concentrations were analysed using Scripps UV titrator and software, measured in ml/L and converted to µmol/L. Dissolved oxygen was analysed using in-house method M5 V02. All data were processed with HyPro 4.12 on the ship and re-processed on shore with HyPro 4.16. Note that nutrient data decimal places have changed within the CSV file: silicate is now 1 decimal place, nitrite is 3 decimal places and NOx (nitrate + nitrite), phosphate and ammonium are 2 decimal places. Previously values below the detection limit were set to zero; these values are now displayed as measured, even if that is a negative value. Salinity and Oxygen Data are displayed to 3 decimal places.

Full description

This record describes Hydrology (HYD) data collected from the Marine National Facility (MNF) RV Investigator voyage IN2025_V06, titled: "The Coral Sea frontier: Deep-sea biodiversity assessment of the Coral Sea Marine Park." The voyage took place between October 10, 2025 and November 14, 2025 (AEST), departing from Brisbane and returning to Brisbane.

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.
