This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2020_V09, titled: "SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania." The voyage took place between August 26, 2020 and September 12, 21020, departing from Hobart and returning to Hobart. This was the first science voyage recommencing the science program for the RV Investigator post-COVID, operating with a reduced ship occupancy. The objective of this voyage primarily was to turn around the SAZ (21 to 22) and SOFS (8 to 9) moorings as part of the Southern Ocean Time Series. ADCP data was collected for the duration of the in2020_v09 voyage. Data was collected using UHDAS and post-processed using CODAS. Both the RDI Ocean Surveyor 150kHz ADCP and the RDI Ocean Surveyor 75kHz ADCP were run in narrowband mode. The drop keel extension was set at 1.19m from the start of the voyage until 29-Aug-2020 00:56:10 when it was changed to 2 m for the rest of the voyage, giving an initial transducer depth of 7.39m and then 8.2m below the waterline for the duration of the voyage respectively. Both units were switched on and off a few times to reduce interference with other acoustic systems utilised during mooring operations. Both units operated in narrow band with some bottom tracking. See the voyage computing and electronics report for more details regarding data acquisition. This dataset was processed (quality-controlled), and then archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).
