March 24 to April 30, 2023, acoustic Doppler current profiler (ADCP) data collected by the CSIRO Marine National Facility RV Investigator during a voyage investigating submarine landslide risks off western Tasmania. Data were processed using the Common Ocean Data Access System (CODAS) and archived by the CSIRO National Collections and Marine Infrastructure Information and Data Centre.
Use Cases
- Analyze ocean current velocity profiles based on acoustic Doppler measurements.
- Study water column dynamics for tsunami risk modeling based on the voyage's landslide investigation focus.
- Validate or calibrate hydrodynamic models using quality-controlled, post-processed current data.
- Investigate instrument performance and fault diagnosis based on the description of OS75 kHz ADCP investigations.
Strengths
- Data collected over a 38-day voyage from March 24 to April 30, 2023.
- Post-processed and quality-controlled using the Common Ocean Data Access System (CODAS).
- Transducer depth is documented as approximately 8.0m below the water line.
Limitations
- Row count and column-level documentation are unknown, limiting suitability assessment.
- A portion of the OS75nb 'part1' data is noted as missing or not useful.
- Description metadata is limited; actual data quality requires manual inspection after download.
