RV Investigator ADCP Current Data from Tasmanian Landslide Voyage, 2023

March 24 to April 30, 2023, Acoustic Doppler Current Profiler (ADCP) data were collected from the RV Investigator voyage IN2023_V02, investigating a submarine landslide off western Tasmania for tsunami risk. The data were processed using the Common Ocean Data Access System (CODAS) and archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre. Instruments included RDI Ocean Surveyor 150kHz and 75kHz ADCPs run in narrowband mode, with transducers located approximately 8.0m below the water line.

Use Cases

• Modeling deep-water current patterns based on acoustic Doppler profiling data.
• Assessing tsunami generation risk from submarine landslides based on voyage investigation focus.
• Calibrating or validating oceanographic instruments using the documented UHDAS and CODAS processing systems.
• Analyzing temporal changes in ocean currents during the 38-day voyage period.

Strengths

• Data collection spanned a specific 38-day voyage from March 24 to April 30, 2023.
• Post-processed using the documented Common Ocean Data Access System (CODAS).
• Instrument deployment details are specified, including transducer depth of approximately 8.0m below the water line.

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• A portion of the OS75nb data was noted as missing or not useful and excluded.
