This record describes Hydrology (HYD) data collected from the Marine National Facility (MNF) RV Investigator voyage: in2016_v03, titled "Monitoring Ocean Change and Variability along 170 W from the ice edge to the equator." The voyage consisted of two legs: Leg-1 from Hobart (TAS) to Wellington (NZ) between April 27 and May 26 and Leg-2 from Wellington (NZ) to Lautoka (Fiji) from May 27 to June 28, 2016.
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This dataset has been archived at the CSIRO O&A Information and Data Centre (IDC) in Hobart.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.
