Brief description
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This dataset has been archived at the CSIRO O&A Information and Data Centre (IDC) in Hobart.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.
Lineage
Statement: Data source: original field data. (1) 140 CTD Stations were completed with a 24-bottle rosette (12L). (2) Salinity was analyzed with the Guildline Autosal Laboratory Salinometer 8400(B). (3) Dissolved oxygen was analyzed using Automated Photometric Oxygen system (SCRIPPS software). (4) Nutrients were analysed using Seal AACE 6.10 software: for Silicate, Phosphate, Nitrate and Nitrite and Ammonia, in units of uM/L. The data produced was processed through a proprietary Matlab application, Hypro (4.12). Note that nutrient data is now provided to 3 decimal places in the CSV file due to new instrumentation and improved detection limit. Previously values below the detection limit were set to zero or <0.02; these values are now displayed as the measured value. For more information please refer to the Data Processing Report.Notes
