Full description
This record describes Hydrology (HYD) data collected from the Marine National Facility (MNF) RV Investigator research voyage in2017_c01, titled "GAB deep water geological and benthic ecology program." The voyage took place from Hobart (TAS) to Hobart between April 11 and April 28, 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This dataset has been archived at the CSIRO O&A Information and Data Centre (IDC) in Hobart.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.
Lineage
Statement: Data source: original field data. See in2017_c01_HYD_ProcessReport document for method details. (1) 6 CTD stations were sampled with a 36 bottle rosette (12 L). (2) Salinity was analyzed with the Guildline Autosal Laboratory Salinometer 8400(B) – SN 71611 (3) Dissolved oxygen was analyzed using Automated Photometric Oxygen system (SCRIPPS software) (4) Nutrients were analysed using Seal AA3 using AACE 6.10 software: for Silicate, Phosphate, Nitrate and Nitrite, Ammonia in units of uM/L using HyPro Version 4.17 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 detection limit were set to zero or <0.02, these values are now displayed as the measured value. Please refer to the processing report. On 15/06/2021 the data were updated because of wrong spatial coordinates.Notes
