RV Investigator Voyage IN2024_V05 ADCP Data

CSIRO's RV Investigator voyage IN2024_V05 collected Acoustic Doppler Current Profiler (ADCP) data between November 13 and December 12, 2024. The data, processed by CSIRO's National Collections and Marine Infrastructure Information and Data Centre, documents ocean currents using three RDI Ocean Surveyor instruments in narrowband mode. Collection was intermittent to avoid interference with concurrent fisheries surveys using an EK80 system.

Use Cases

• Modeling ocean current patterns based on ADCP measurements from a dedicated research vessel.
• Analyzing temporal changes in marine ecosystems based on data collected over a 25-year study program (SEA-MES).
• Calibrating acoustic survey equipment based on the described bottom-tracking and instrument configuration details.
• Studying the interaction between physical oceanography and fisheries based on the concurrent use of ADCP and EK80 systems mentioned in the description.

Strengths

• Data originates from a dedicated national facility research voyage (RV Investigator) over a defined 30-day period.
• Processing involved quality-controlled archival by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.
• Multiple instrument frequencies (38kHz, 75kHz, 150kHz) were used, likely providing current profiles at different depth ranges.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• ADCP data acquisition was not continuous, with long periods turned off during EK80 surveys, creating gaps.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
