RV Investigator Voyage IN2017_V04 Hydrology Data

This record describes Hydrology (HYD) data collected from the Marine National Facility (MNF) RV Investigator research voyage IN2017_V04, titled "The whole enchilada: from production to predation in Tasman Sea ecosystems." The voyage took place from Brisbane (QLD) to Sydney (NSW) between August 31 and September 18, 2017.Hydrology samples were collected from Niskin bottles sampled at various depths during a Conductivity-Temperature-Depth (CTD) deployment. Parameters analysed were salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite and ammonium. Underway samples were also collected every 12 hours (or once every 24 if a CTD coincided with collection time) for nutrient analysis from the underway system which collects water from 7 m depth and is not filtered. This dataset has been archived at the CSIRO O&A Information and Data Centre (IDC) in Hobart.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.
