Dataset: RV Investigator Voyage IN2016_V06 CTD Data


Description

This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2016_V06 titled: "Sustained monitoring of the EAC: mass, heat and freshwater". The voyage took place between 29 October and 13 November, 2016 departing from Brisbane (QLD) and arriving in Brisbane.

Data for 12 deployments were acquired using the Seabird SBE911 CTD unit 20, fitted with 24 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 primary sensor had a standard deviation (S.D) of 0. 0013601 PSU, within our target of ‘better than 0.002 PSU’. The standard product of 1dbar binned averaged were produced using data from the primary sensors. The dissolved oxygen data calibration fit had a S.D. of 0. 84677 uM. The agreement between the CTD and bottle data was good. The Biospherical photosynthetically active radiation (PAR), C-Star transmissometer and the Wetlabs ECO chlorophyll and CDOM sensors were also installed on the auxiliary A/D channels of the CTD

The collected data were subsequently processed and archived within the CSIRO Oceans and Atmosphere (O&A) 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.
