RV Investigator Voyage IN2023_V02 Acoustic Doppler Current Profiler Data

Acoustic Doppler Current Profiler (ADCP) data collected during the RV Investigator voyage IN2023_V02, which investigated a submarine landslide offshore western Tasmania. The voyage took place between March 24, 2023 and April 30, 2023, departing from and returning to Hobart. Data were collected using RDI Ocean Surveyor instruments, processed with CODAS, and archived by CSIRO's National Collections and Marine Infrastructure.

Use Cases

• Modeling deep-water current profiles based on ADCP measurements from the voyage.
• Analyzing oceanographic conditions during a submarine landslide investigation based on the voyage's purpose.
• Calibrating or validating acoustic current profiler data processing pipelines based on the described UHDAS and CODAS systems.

Strengths

• Data is quality-controlled and archived by CSIRO's National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).
• Specific voyage time range (March 24 to April 30, 2023) and departure/return location (Hobart) are documented.
• Instrument deployment details are provided, including transducer depth (approximately 8.0m below water line) and operational mode (narrowband).

Limitations

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