RV Investigator Voyage IN2024_V05 Acoustic Doppler Current Profiler Data

Acoustic Doppler Current Profiler (ADCP) data was collected by the CSIRO Marine National Facility RV Investigator during voyage IN2024_V05 from November 13 to December 12, 2024. The data covers the southeast marine ecosystem and was processed using the University of Hawaii Data Acquisition System (UHDAS) and Common Ocean Data Access System (CODAS). It was archived by the CSIRO National Collections and Marine Infrastructure Information and Data Centre.

Use Cases

• Analyze ocean current velocity profiles based on ADCP measurements.
• Study temporal changes in marine ecosystems based on data collected over a multi-year project.
• Calibrate acoustic survey equipment based on the described bottom tracking and interference mitigation procedures.
• Model physical oceanographic processes in the southeast marine region based on the voyage's geographic focus.

Strengths

• Data was collected over a defined voyage period from November 13 to December 12, 2024.
• Post-processed using documented systems (UHDAS and CODAS) with a linked processing report.
• Includes data from three specific ADCP instruments (RDI Ocean Surveyor 150kHz, 75kHz, 38kHz) operated in narrowband mode.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The ADCP was not acquiring data for long periods due to interference with concurrent EK80 fisheries surveys.
• Row count is unknown, which may limit suitability assessment.
