RV Investigator Voyage IN2024_V02: Acoustic Doppler Current Profiler Data

Acoustic Doppler Current Profiler (ADCP) data was collected during the RV Investigator voyage IN2024_V02, titled 'SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania.' The voyage occurred between March 31, 2024 and April 19, 2024, departing from and returning to Hobart. Data were processed by CSIRO National Collections and Marine Infrastructure.

Use Cases

• Modeling ocean current dynamics based on ADCP measurements from the Southern Ocean.
• Analyzing temporal variability in water column currents for climate studies based on the time-series mooring mission.
• Investigating instrument performance and data quality issues based on the described checksum errors and suspected water ingress.

Strengths

• Data was collected during a dedicated 20-day research voyage focused on climate and carbon cycle studies.
• Post-processing was performed using established systems (UHDAS and CODAS) with referenced documentation.
• Specific instrument configurations and deployment depths (e.g., port keel transducer at ~8.0m) are documented.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data collection was interrupted for specific instruments (WH75) due to technical issues.
