Full description

This record describes the Conductivity-Temperature-Depth (CTD) 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.

Data for 66 deployments were acquired using the Sea-Bird SBE911 CTD 24, fitted with 31 twelve litre bottles on the rosette sampler. Sea-Bird-supplied calibration factors were used to compute the pressures and preliminary conductivity values. CSIRO -supplied calibrations were applied to the temperature data. The data were subjected to automated QC to remove spikes and out-of-range values.

The final conductivity calibration was based on a single deployment grouping. The final calibration from the secondary sensor had a standard deviation (SD) of 0.0013390 PSU, well within our target of ‘better than 0.002 PSU’. The standard product of 1 decibar binned averaged were produced using data from the secondary sensors.

The dissolved oxygen data calibration fit had a SD of 0.83871 μM. The agreement between the CTD and bottle data was good. Transmissometer, Wetlabs FLBBRTD, Altimeter and Wetlabs FLCDRTD were also installed on the auxiliary A/D channels of the CTD.

The collected data were subsequently processed and archived within the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC) in Hobart. Additional information regarding this dataset may be contained in the Voyage Summary and the CTD Data Processing Report.
