Full description

This record describes the CTD data collected on Investigator voyage IN2024_V05, titled: "Multi-year: Untangling the causes of change over 25 years in the southeast marine ecosystem (SEA-MES Voyage 3)." The voyage took place between November 13, 2024 and December 12, 2024 (AEST), departing from Hobart and returning to Hobart.

Data for 94 CTD deployments were acquired using the Sea-Bird SBE911 CTD unit #24 (Serial Number 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.

Calibration for Active Heave Compensation (AHC) appears to have changed post dry dock, resulting in loops on SeaSave plots after AHC is turned on. This also caused the CTD wire to become slack due to the compensation sending out too much wire. Rapp McGregor assisted the Chief Engineer to dial down the maximum winch speed to prevent wire slack from occurring on up heave, in the event the winch compensation was in phase with the actual heave. The issue was observed to cause an additive effect instead of the intended effect of keeping the CTD steady. The issue was further investigated and resolved following the voyage.

The final conductivity calibration was based on a single deployment grouping. The final calibration from the primary sensor had a standard deviation (SD) of 0.0015089 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 primary sensors.

The dissolved oxygen data calibration fit had a SD of 0.83742 μM. The agreement between the CTD and bottle data was good.
Fluorometer, transmissometer, PAR, CDOM and turbidity sensors were also 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).
