This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2018_V01, titled: "Detecting Southern Ocean change from repeat hydrography, deep Argo and trace element biogeochemistry & CAPRICORN." The voyage took place between the January 11 and February 22, 2018 departing Hobart (TAS) and returning to Hobart. Only the RDI Ocean Surveyor 75kHz ADCP was operational during this voyage. The RDI Ocean Surveyor 150kHz ADCP was not operated due to a hardware fault, so all data was collected with the RDI Ocean Surveyor 75kHz ADCP, which was run in narrow band mode only. The first four days of the voyage had a degraded seapath data feed to UHDAS. It appeared that the seapath D-GPS had been working in GNSS mode and not DGNSS. These issues were addressed by a reconfiguration of UHDAS to get a better heading calibration for the first part of the voyage and a subsequent part2 of the voyage was created. Internal triggering was used as the focus of this voyage was to collect current data and external triggering was found to be unstable on previous voyages. Port drop keel was flush with gondola for the majority of the voyage at 2m in the period between 2018-01-11T21:00:20Z and 2018-02-21T20:55:30Z. This dataset was processed and then archived within the CSIRO Oceans and Atmosphere (O&A) Information and Data Centre (IDC) in Hobart.
