RV Investigator Voyage IN2024_V05: Acoustic Doppler Current Profiler Data

Southeast Australian marine ecosystem data collected from the RV Investigator voyage IN2024_V05 between November 13 and December 12, 2024. Acoustic Doppler Current Profiler (ADCP) data were gathered using three RDI Ocean Surveyor instruments and processed with the CODAS system. The dataset was quality-controlled and archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.

Use Cases

• Modeling ocean current profiles based on ADCP measurements from three frequency instruments.
• Analyzing temporal changes in marine ecosystems based on data from a dedicated month-long research voyage.
• Calibrating acoustic survey equipment using bottom-tracking data collected for one hour.
• Studying vessel interference patterns in acoustic data based on described ADCP and EK80 usage protocols.

Strengths

• Data collected over a dedicated 30-day research voyage (November 13 to December 12, 2024).
• Processed using the documented Common Ocean Data Access System (CODAS).
• Includes measurements from three specific ADCP instruments (38kHz, 75kHz, 150kHz) in narrowband mode.
• Quality-controlled and archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.

Limitations

• ADCP data collection was intermittent, with instruments turned off during extensive EK80 fisheries surveys.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
