RV Investigator Voyage IN2022_V03 ADCP Data

This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2022_V03 titled: "SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania". The voyage took place between May 4 and May 15, 2022 departing from Hobart (TAS) and returning to Hobart (TAS). .

The ADCP was run for most of the voyage, it was switched to passive mode during PLAOS (Profiling Lagrangian Acoustic Optical System) deployments due to interference with the USBL. The 75 kHz ADCP was turned off in shallow water reducing interference with the EM710.

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. Internal triggering was used. The drop keel was set at 7m below the waterline for the duration of the voyage.

Please refer to the voyage Computing and Instrumentation reports for further 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).
