IN2021_V02: Southern Ocean Current Profiler Data from RV Investigator Voyage

Acoustic Doppler Current Profiler (ADCP) data collected during the RV Investigator voyage IN2021_V02 between April 14 and April 28, 2021. The voyage, titled 'SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies', departed from and returned to Hobart, Tasmania. CSIRO National Collections and Marine Infrastructure processed and archived this quality-controlled dataset.

Use Cases

• Modeling ocean current patterns based on acoustic Doppler profiling data.
• Studying temporal variability in water column currents during the April 2021 voyage period.
• Integrating current data with other Southern Ocean Time Series (SOTS) mooring observations for climate studies.
• Assessing potential data gaps due to instrument outages mentioned during multibeam or acoustic release operations.

Strengths

• Data was processed using the University of Hawaii's CODAS software (codas_focal_20.04_vbox64.ova), indicating a standardized quality-control procedure.
• The voyage had a defined temporal coverage from April 14 to April 28, 2021, and a known geographic focus southwest of Tasmania.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal and geographic bias inherent to the specific two-week voyage.
