This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2021_E04, titled "Trials & Calibrations." The voyage took place between December 15, 2021 and December 20, 2021 (AEST), departing from Hobart and returning to Hobart. Data was collected during IN2021_E04 for sections of the voyage. Data was collected using UHDAS and post-processed using CODAS. The RDI Ocean Surveyor 150kHz ADCP (os150) was run in broadband with 4m bins from the start of the voyage, while in relatively shallow water, from 2021-12-14 22:12Z. The OS150 was turned off at 2021-12-15 21:17Z to avoid interference with other sounders data that were being collected. From 2021-12-16 10:50Z both the os150 and the RDI Ocean Surveyor 75kHz ADCP (os75) were run in narrowband with 8m bins. The os75 was switch off at 2021-12-19 21:10Z as the vessel entered shallower water. The os150 was switched off at the end of the voyage at 2021-12-19 12:45Z. Internal triggering was used. The drop keel was ‘flush with the gondola’ at 1.19m below the waterline for the duration of the voyage. This dataset was processed (quality-controlled), and then archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).
