The voyage took place between January 14 and March 5, 2017 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. Note that the underway samples (dataset: in2017_v01uwyHydro_csv.zip) time extents range from 16/01/2017 to 01/03/2017 and the spatial extents are slightly greater than those specified in the Geographic Bounding Box below. This dataset has been archived at the CSIRO O&A Information and Data Centre (IDC) in Hobart.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.Progress Code: completedStatement: Data source: original field data. 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 Automated Photometric Oxygen system. All data were processed with HyPro 4.16 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.

Brief description

This record describes Hydrology (HYD) data collected from the Marine National Facility (MNF) RV Investigator voyage IN2017_V01 titled: "Interactions of the Totten Glacier with the Southern Ocean through multiple glacial cycles." The voyage took place between January 14 and March 5, 2017 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.

Note that the underway samples (dataset: in2017_v01uwyHydro_csv.zip) time extents range from 16/01/2017 to 01/03/2017 and the spatial extents are slightly greater than those specified in the Geographic Bounding Box below.


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.

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 Automated Photometric Oxygen system.

All data were processed with HyPro 4.16 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.
