RV Investigator IN2024_V02: Southern Ocean Current Profiles from ADCP

Acoustic Doppler Current Profiler (ADCP) data from the RV Investigator voyage IN2024_V02, focused on the Southern Ocean Time Series. The voyage occurred between March 31 and April 19, 2024, departing from and returning to Hobart. Data were collected using the University of Hawaii Data Acquisition System (UHDAS) and post-processed using CODAS, then archived by CSIRO's National Collections and Marine Infrastructure.

Use Cases

• Modeling ocean current velocities based on ADCP measurements.
• Analyzing temporal variability in water column dynamics during the voyage period.
• Studying instrument performance and data gaps based on described logging issues with the WH75.
• Investigating the impact of keel depth configuration on acoustic data collection.

Strengths

• Data is quality-controlled and post-processed using the established CODAS system.
• Specific voyage time range is provided: March 31 to April 19, 2024.
• Instrument configurations and operational details are documented, including keel depths and triggering modes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data includes described gaps and instrument errors, such as the WH75 checksum issues.
