CSIRO processed Acoustic Doppler Current Profiler data from a voyage investigating a gigantic submarine landslide offshore western Tasmania. The voyage took place between March 24, 2023 and April 30, 2023, departing and returning to Hobart. Data were collected using RDI Ocean Surveyor instruments and processed with the Common Ocean Data Access System.
Use Cases
- Modeling tsunami risk based on current profiles collected near a submarine landslide site.
- Analyzing ocean current patterns based on ADCP data collected over a 38-day voyage.
- Diagnosing instrument performance based on investigations into the OS75 kHz ADCP fault mentioned in the description.
- Studying water column dynamics based on data from transducers located approximately 8.0m below the water line.
Strengths
- Data were processed and quality-controlled by CSIRO National Collections and Marine Infrastructure.
- Voyage duration and specific instrument configurations are documented, including transducer depth of approximately 8.0m.
- Post-processing methodology is documented, referencing the Common Ocean Data Access System.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- The OS75nb 'part1' data were missing or not useful and excluded from downloadable links.
- Row count is unknown, which may limit suitability assessment.
