Full description
This record describes Hydrology (HYD) data collected from the Marine National Facility (MNF) RV Investigator voyage IN2020_V08, titled: "SOLACE - Southern Ocean Large Areal Carbon Export: quantifying carbon sequestration in subpolar and polar waters." The voyage took place between December 4, 2020 and January 15, 2021 departing from Hobart (TAS) and arriving in Hobart.Hydrology samples were collected from Niskin bottles sampled at various depths during Conductivity-Temperature-Depth (CTD) deployments. Parameters analysed were salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite and ammonium.
This dataset has been archived at the CSIRO O&A Information and Data Centre (IDC) in Hobart.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. Nutrient 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 (in2020_v08_HYD_ProcessingReport.pdf). NOTE ON TMR CSV FILE (12/03/2021): The metadata for the TMR data had been kept on logsheets for each deployment which were later collated into one master logsheet. The ship's main eLog (assumed to be more accurate than the log sheets referred to above) was used to populated the Lat, Lon and Time Deployed for the TMR csv file. The Pressure column was populated from logs of other samples taken; the numbers appear to add up correctly. The discrepancies are on cast #2 (only 6 samples ran, 12 on log sheet), #11 (only 3 samples ran, 12 on log sheet) and #12 (only 10 samples ran).Notes
