RV Investigator ADCP Data from the Gigantic Submarine Landslide Voyage, 2023

Acoustic Doppler Current Profiler data collected during the RV Investigator voyage IN2023_V02, which investigated a gigantic submarine landslide offshore western Tasmania. The voyage took place between March 24 and April 30, 2023, departing from and returning to Hobart. Data were processed and archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.

Use Cases

• Modeling deep-water current patterns based on ADCP measurements from the research vessel.
• Assessing submarine landslide dynamics and associated tsunami risks based on the voyage's stated scientific objective.
• Calibrating oceanographic models using quality-controlled data processed with the CODAS system.

Strengths

• Data were collected over a 38-day voyage, providing a continuous time series.
• Data were post-processed using the Common Ocean Data Access System (CODAS), indicating a level of quality control.
• The transducer depth is precisely documented as approximately 8.0m below the water line.

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 OS75kHz ADCP data was noted as missing or not useful.
