Brief description
This record describes Hydrology (HYD) data collected from the Marine National Facility (MNF) RV Investigator voyage IN2019_T01, titled: "Collaborative Australian Postgraduate Sea Training Alliance (CAPSTAN)". The voyage took place from Hobart (TAS) to Freemantle (WA) between April 29 and May 9, 2019.The main objective of the voyage was to provide post-graduate students hands-on training experiences with standard modern sampling equipment used in marine research, encompassing geological, biological, chemical, physical oceanographic and atmospheric equipment.
Water samples collected during the voyage were assayed in the ship’s hydrochemistry laboratory for nutrients, dissolved oxygen, and their salinity measured. The samples came from deployments of the conductivity, temperature and depth (CTD) rosette.
Five nutrients were analysed; silicate, phosphate, nitrate + nitrite, nitrite and ammonium. Certified reference materials for nutrients in seawater were within the specified limits of the certified value.
This dataset has been archived at the CSIRO O&A Information and Data Centre (IDC) in Hobart. Additional information regarding this dataset is contained in the Voyage Report and Data Processing Report.
Lineage
Progress Code: completedNutrient samples were analysed using segmented flow SEAL AA3 and results are in µmol/L. In-house methods SOP 001, SOP 002, SOP 003 and SOP 004 were used to analyse nutrients.
Salinities were analysed using Guildline 8400B Autosal Lab Salinometer and OSIL software. The salinometer was calibrated with IAPSO standard seawater P162. In-house method SOP 006 was used to analyse salinity, units are Practical Salinity Unit (PSU).
Dissolved Oxygens were analysed using Scripps UV titrator and software, units measured in ml/L and converted to µmol/L. Dissolved oxygen was analysed using in-house method SOP 005.
All data was processed with HyPro 4.17.
Data processing notes are in the processing report (in2019_t01_HYD_ProcessingReport.pdf).
