RV Investigator Voyage IN2023_V02: Acoustic Doppler Current Profiler Data

Marine National Facility RV Investigator voyage IN2023_V02 collected Acoustic Doppler Current Profiler (ADCP) data offshore western Tasmania between March 24 and April 30, 2023. The data were collected using RDI Ocean Surveyor 150kHz and 75kHz ADCPs in narrowband mode, processed with CODAS, and archived by CSIRO. The voyage aimed to investigate a gigantic submarine landslide for tsunami risk mitigation.

Use Cases

• Modeling ocean current profiles based on acoustic Doppler measurements.
• Investigating water column dynamics for tsunami risk assessment based on the voyage's stated purpose.
• Analyzing instrument performance in narrowband mode based on the described data collection method.
• Studying subsurface landslide impacts on hydrography based on the voyage's research focus.

Strengths

• Data were quality-controlled and archived by CSIRO National Collections and Marine Infrastructure.
• Specific voyage dates (March 24 to April 30, 2023) and departure/return location (Hobart) are provided.
• Instrument deployment details are specified, including transducer depth at approximately 8.0m below the water line.

Limitations

• 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.
• Row count and dataset size are unknown, which may limit suitability assessment.
