This dataset contains the processed Conductivity-Temperature-Depth (CTD) data collected on Maritime Image voyage NA200410, processed by SRFME staff and is archived within the CSIRO Marine and Atmospheric Research Data Centre in Floreat. This dataset is part of the SRFME research program.

This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2016_V04, titled: "Influence of temperature and nutrient supply on the biogeochemical function and diversity of ocean microbes." The voyage took place between August 31 and September 22, 2016 departing from Sydney(NSW) and arriving in Brisbane (QLD). Data for 56 deployments were acquired using the Seabird SBE911 CTD 20, fitted with 24 ten-litre bottles on the rosette sampler. The Seabird SBE911 has dual conductivity and temperature sensors. The CTD was additionally fitted with SBE43 dissolved oxygen sensors, fluorometer, transmissometer, PAR sensor and LADCP sensors. These sensors are described in the processing report. The collected data was subsequently processed and archived within the CSIRO Oceans and Atmosphere (O&A) in Hobart. Additional information regarding this dataset may be contained in the Voyage Summary and the CTD Data Processing Report.

This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2022_V07, titled "HALO - Halimeda bioherm Origins, function and fate in the northern Great Barrier Reef." The voyage took place between August 15, 2022 and September 7, 2022 (AEST), departing from Brisbane and returning to Cairns. Data for 21 deployments were acquired using the Sea-Bird SBE911 CTD Report, fitted with 36 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 for the primary channel and two deployment groupings for the secondary channel. The final calibration from the secondary sensor had a standard deviation (SD) of 0.0012964 PSU for casts 1-19 and 0.0011836 for casts 20-21, 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 was based on two groupings which had a SD of 0.77590 μM for casts 1-16 and 0.90173 μM for casts 17-21 on the secondary channel. The agreement between the CTD and bottle data was good. An altimeter, PAR, transmissometer, CDOM, chlorophyll and scattering sensors were also installed on the auxiliary A/D channels of the CTD. The collected data were subsequently processed (quality-controlled), and archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC). Additional information regarding this dataset may be contained in the Voyage Summary and the CTD Data Processing Report.

This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2020_V10, titled: "MNF Trials, Storm Bay Modelling and Information System Data Collection, and Bathymetric and Benthic Habitat mapping of the Huon AMP." The voyage took place between November 13 and November 22, 2020 departing from Hobart (TAS) and returning to Hobart. Data for 9 deployments were acquired using the Sea-Bird SBE911 CTD 24, fitted with 36 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 0.0011549 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 primary sensor data calibration fit had a SD of 0.38919μM. The agreement between the CTD and bottle data was good. A PAR, Transmissometer, Chelsea Fluorometer, and Wetlabs Fluorometer 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.
