RV Investigator Voyage IN2023_V02: Acoustic Doppler Current Profiler Data from Tasmania

Acoustic Doppler Current Profiler data collected during a 38-day voyage investigating a submarine landslide for tsunami risk mitigation off western Tasmania. The voyage, conducted by the Marine National Facility RV Investigator, departed and returned to Hobart between March 24 and April 30, 2023. Data were processed by CSIRO's National Collections and Marine Infrastructure Information and Data Centre using the University of Hawaii Data Acquisition System and Common Ocean Data Access System.

Use Cases

• Modeling ocean current profiles based on ADCP measurements from a research vessel.
• Analyzing water column dynamics for tsunami risk studies based on the voyage's stated purpose.
• Calibrating or diagnosing ADCP instrument performance based on the description of fault investigations.
• Studying the impact of keel depth on acoustic measurements based on the described 8.0m transducer location.

Strengths

• Data is quality-controlled and archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.
• Specific voyage duration and geographic focus are provided: March 24 to April 30, 2023, offshore western Tasmania.
• Instrument configuration details are noted, including narrowband mode and keel depth of approximately 8.0m.

Limitations

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