IN2024_V02: Southern Ocean Current Profiles from RV Investigator Voyage

Acoustic Doppler Current Profiler (ADCP) data from the RV Investigator's Southern Ocean Time Series voyage between March 31 and April 19, 2024. The dataset was collected using UHDAS and post-processed with CODAS, then archived by CSIRO's National Collections and Marine Infrastructure. Data collection was interrupted for specific instruments due to suspected water ingress and to reduce acoustic interference during other scientific operations.

Use Cases

• Modeling ocean current dynamics based on ADCP profiles collected from drop keels.
• Analyzing temporal variability in the Southern Ocean based on a dedicated time-series voyage.
• Studying instrument performance and data gaps based on described logging interruptions and checksum errors.
• Correlating acoustic survey data with current measurements based on described operational interference protocols.

Strengths

• Data was collected during a dedicated 20-day research voyage (March 31 to April 19, 2024) for climate studies.
• Post-processed using the established Common Ocean Data Access System (CODAS) with referenced documentation.
• Instrument deployment details are specified, including keel depths of approximately 6m and 8m 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.
• Data collection experienced interruptions for the WH75 instrument due to checksum errors and suspected water ingress.
