The voyage took place between January 25 and March 2, 2023, departing from Henderson (WA) and returning to 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 processed (quality-controlled), and archived at the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC) in Hobart. Additional information regarding this dataset is contained in the Voyage Report and Data Processing Report.Maintenance and Update Frequency: asNeededStatement: Data source: original field data. Water column and underway samples collected during the voyage were analysed in the ship’s hydrochemistry laboratory for dissolved oxygen (DO), salinity and, nutrients (silicate, phosphate, nitrate + nitrite (NOx), nitrite and ammonium). Overall, the quality of IN2023_V01 hydrology data is good. The measured nutrient reference materials (RMNS) were within 2% of their values. The bottle salinities and dissolved oxygen results were mostly within 0.004 PSU and 12 μmol L-1 respectively of the unprocessed CTD measurements. Nutrient samples were analysed using segmented flow SEAL AA3 and results are in µmol/L. In-house methods M1 V01, M2 V01, M3 V01, M4 V03 were used to analyse nutrients. Salinities were analysed using Guildline 8400B Autosal Lab salinometer and OSIL software, units are salinity units. Dissolved Oxygen concentrations were analysed using Scripps UV titrator and software, measured in ml/L and converted to µmol/L. Dissolved oxygen was analysed using in-house method M5 V02. All data were processed with HyPro 4.12 on the ship and re-processed on shore with HyPro 4.16. Note that nutrient data decimal places have changed within the CSV file: silicate is now 1 decimal place, nitrite is 3 decimal places and NOx (nitrate + nitrite), phosphate and ammonium are 2 decimal places. Previously values below the detection limit were set to zero; these values are now displayed as measured, even if that is a negative value. Salinity and Oxygen Data are displayed to 3 decimal places. Data processing notes are in the processing report (in2023_v01_HYD_ProcessingReport.pdf). The compressed file IN2023_V01_HYD_UWY_CSV.zip had NOX results swapped with PO4 results (sample 41 on).It was updated on 28/04/2023.&rft.creator=Anonymous&rft.date=2023&rft.coverage=westlimit=64.024; southlimit=-65.893; eastlimit=147.512; northlimit=-31.942; projection=WGS 84 (EPSG:4326)&rft.coverage=westlimit=64.024; southlimit=-65.893; eastlimit=147.512; northlimit=-31.942; projection=WGS 84 (EPSG:4326)&rft_rights=Attribution 4.0 https://creativecommons.org/licenses/by/4.0/&rft_rights=&rft_rights=Data is made available under a Creative Commons Attribution 4.0 International Licence, please see link.

Full description

This record describes Hydrology (HYD) data collected from the Marine National Facility (MNF) RV Investigator voyage IN2023_V01, titled: "Canyons: Antarctic Bottom Water Production in the past: Records from marine sediments, Cape Darnley, East Antarctica." The voyage took place between January 25 and March 2, 2023, departing from Henderson (WA) and returning to 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 processed (quality-controlled), and archived at the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC) in Hobart. Additional information regarding this dataset is contained in the Voyage Report and Data Processing Report.
