RV Investigator Voyage IN2023_V01 CTD Data

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 locationThe 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.
