This record describes Hydrology (HYD) data collected from the Marine National Facility RV Investigator voyage IN2021_V01, titled: "Quantifying krill abundance for krill monitoring and management off the Australian Antarctic Territory." The voyage took place between January 29 and March 25, 2021 departing from Hobart (TAS) and arriving in Hobart. .
Water samples collected during the voyage were analysed in the ship’s hydrochemistry laboratory for nutrients, dissolved oxygen, and salinity.
Five nutrients were determined: silicate, phosphate, nitrate + nitrite, nitrite and ammonium. Certified reference materials for nutrients in seawater (RMNS) were within 3% of their certified values. CTD deployment versus measured RMNS values are listed in Appendix 8.2
Missing and suspect hydrology data are listed in Appendix 8
Final hydrology data, analytical methods, related log sheets and processing notes can be obtained from the CSIRO data centre.
This dataset has been archived at the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC) in Hobart.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.
