RV Investigator Voyage IN2024_V05: Acoustic Doppler Current Profiler Data

November 13 to December 12, 2024, Acoustic Doppler Current Profiler (ADCP) data collected during the RV Investigator voyage IN2024_V05, titled 'Multi-year: Untangling the causes of change over 25 years in the southeast marine ecosystem (SEA-MES Voyage 3)'. The data were collected using three RDI Ocean Surveyor ADCPs in narrowband mode, processed with the Common Ocean Data Access System (CODAS), and archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.

Use Cases

• Modeling ocean current profiles based on acoustic Doppler measurements.
• Analyzing temporal changes in marine ecosystems based on data collected over a multi-year research program.
• Calibrating acoustic survey instruments using bottom-tracking data collected for an hour on the OS150nb.
• Studying the interaction between fisheries acoustics (EK80) and current profiler operations based on described interference management.

Strengths

• Data collected over a defined voyage period from November 13 to December 12, 2024.
• Processed and quality-controlled using the established Common Ocean Data Access System (CODAS).
• Includes data from three specific ADCP instruments: RDI Ocean Surveyor 150kHz, 75kHz, and 38kHz.
• Archived by the authoritative CSIRO National Collections and Marine Infrastructure Information and Data Centre.

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.
