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. Seven CTD casts were performed in total.

The data were acquired with the CSIRO CTD unit #23 (S/N 1312), a Sea-Bird SBE911 with dual conductivity and temperature sensors. The CTD was additionally fitted with SBE43 dissolved oxygen sensors including Altimeter, Nepthelometer, Transmissometer, CDOM, chlorophyll-a, and Scattering. Water samples were collected using a Sea-Bird SBE32, 12-litre 36-bottle rosette sampler which was fitted to the frame. The raw CTD data were collected in SBE Seasave version 7.26.7.110, converted to scientific units using SBE Data Processing version 7.26.7.129 and written to NetCDF files with CNV_to_Scan (cnv_to_scan_ui2.py, from the CSIRO MNF Data Acquisition and Processing “marinetech” git repository) for processing using the MATLAB-based CapPro software. The CapPro software version 2.12 was used to apply automated QC and preliminary processing to the data. This included spike removal, identification of water entry and exit times, conductivity sensor lag corrections, conductivity cell thermal inertia corrections, and the determination of the pressure offsets. It also loaded the hydrology data and computed the matching CTD sample burst data (i.e., averaged sensor data) for water-sample-to-sensor data comparisons.The automatically determined pressure offsets and in-water points were inspected and verified during data processing. The bottle sample data were used to compute final conductivity and dissolved oxygen calibrations. These were applied to the data, after which files of binned 1-decibar averaged data were produced.

Full description

This record describes the CTD data collected on Investigator voyage IN2023_V01, titled: "Antarctic Bottom Water Production in the past: Records from marine sediments, Cape Darnley, East Antarctica" The voyage took place between January 25 and March 2, 2023, departing from Henderson (WA) and returning to Hobart (TAS).

Data for 6 CTD deployments were acquired using the Sea-Bird SBE9+V2 CTD unit #23 (S/N 1312), 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. Seven CTD casts were performed in total. Casts #1-4 were performed in the original planned survey area, while casts #5-7 were performed at the alternative opportunistic science location

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