The voyage took place between June 27, 2023 and July 29, 2023 (AEST), departing from Hobart and returning to Hobart. Data for 62 CTD deployments were acquired using the Sea-Bird SBE9+V2 CTD unit #24 (S/N 1332), 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 spikesand out-of-range values.The initial configuration of the CTD for casts #1-22 is shown in table 1 below. For casts #23-62 , the CDOM sensor on channel A4 was replaced by the Chelsea Aquatracka fluorometer (as indicated in table 1 below) due to suspiciously high readings obtained using the Wetlabs FLBBRTD fluorometer near the water surface. The Chelsea unit yielded a similar response, providing confidence that theunexpectedly high chlorophyll readings near the surface were not caused by sensor issues.The final conductivity calibration was based on a single deployment grouping. The final calibration from the secondary sensor had a standard deviation (SD) of 0.0013744 PSU, well within our target of ‘better than 0.002 PSU’. The standard product of 1-decibar binned averages were produced using data from the secondary sensors.The dissolved oxygen data (primary) calibration fit had a SD of 0.7868 μM. The agreement between the CTD and bottle data was good.Additional sensors include: SUNA Nitrate, Altimeter (Tritech PA500), Transmissometer (Wetlabs CStar), CDOM (replaced by Chealsea Aquatracka after cast #22), Chlorophyll-a, Scattering (Wetlabs ECO FLCDRTD) were installed on the auxiliary A/D channels of the CTD.The collected data were processed (quality-controlled), and subsequently 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 Data Processing Report.Maintenance and Update Frequency: asNeededStatement: Original field data.

Full description

This record describes the CTD data collected on Investigator voyage IN2023_V05, titled: "Untangling the causes of change over 25 years in the southeast marine ecosystem (SEA-MES Voyage 1)." The voyage took place between June 27, 2023 and July 29, 2023 (AEST), departing from Hobart and returning to Hobart.

Data for 62 CTD deployments were acquired using the Sea-Bird SBE9+V2 CTD unit #24 (S/N 1332), 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 initial configuration of the CTD for casts #1-22 is shown in table 1 below. For casts #23-62 , the CDOM sensor on channel A4 was replaced by the Chelsea Aquatracka fluorometer (as indicated in table 1 below) due to suspiciously high readings obtained using the Wetlabs FLBBRTD fluorometer near the water surface. The Chelsea unit yielded a similar response, providing confidence that the
unexpectedly high chlorophyll readings near the surface were not caused by sensor issues.
The final conductivity calibration was based on a single deployment grouping. The final calibration from the secondary sensor had a standard deviation (SD) of 0.0013744 PSU, well within our target of ‘better than 0.002 PSU’. The standard product of 1-decibar binned averages were produced using data from the secondary sensors.
The dissolved oxygen data (primary) calibration fit had a SD of 0.7868 μM. The agreement between the CTD and bottle data was good.
Additional sensors include: SUNA Nitrate, Altimeter (Tritech PA500), Transmissometer (Wetlabs CStar), CDOM (replaced by Chealsea Aquatracka after cast #22), Chlorophyll-a, Scattering (Wetlabs ECO FLCDRTD) were installed on the auxiliary A/D channels of the CTD.

The collected data were processed (quality-controlled), and subsequently archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).
