See in2018_v02_HYD_ProcessingReport.pdf document for method details. (1) 7 CTD stations were sampled with a 36 bottle rosette, (12L). (2) Nutrient samples were analysed using segmented flow SEAL AA3HR and results are in µmol/L. (3) Salinities were analysed using Guildline 8400B Autosal Lab Salinometer and OSIL software. The salinometer was calibrated with IAPSO standard seawater P161. (4) 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.

Full description

This record describes Hydrology (HYD) data collected collected from the Marine National Facility RV Investigator Voyage IN2018_V02, titled: "SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies south west Tasmania; Subantarctic Biogeochemistry of Carbon and Iron." The voyage took place between March 3 and March 21, 2018 departing from Hobart (TAS) and arriving in Hobart.

Water samples collected during the voyage were assayed in the ship’s hydrochemistry laboratory for nutrients, dissolved oxygen, and their salinity measured. The samples came from deployments of the CTD rosette and trace metal rosette as well as from experiments run by the science party.

Results for nutrient samples from experiments issued to the science parties during the voyage.

Final hydrology data, analytical methods, and related log sheets and processing notes can be obtained from the CSIRO data centre.


This dataset has been archived at the CSIRO O&A Information and Data Centre (IDC) in Hobart.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.
