IN2024_V05: Acoustic Doppler Current Profiler Data from Southeast Australian Waters

Southeast Australian marine ecosystem data collected by the RV Investigator between November 13 and December 12, 2024. Acoustic Doppler Current Profiler (ADCP) data were gathered using 150kHz, 75kHz, and 38kHz instruments in narrowband mode, processed with the CODAS system. The dataset was archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.

Use Cases

• Modeling ocean current profiles based on multi-frequency ADCP measurements
• Analyzing temporal changes in water column structure during a fisheries survey voyage
• Calibrating acoustic instruments using the documented bottom-tracking data
• Studying vessel interference patterns between ADCP and EK80 echosounder systems

Strengths

• Data collected over a 30-day voyage in a defined marine ecosystem study area
• Processed using the documented Common Ocean Data Access System (CODAS)
• Includes data from three ADCP instruments (150kHz, 75kHz, 38kHz) for potential cross-validation

Limitations

• ADCP acquisition was interrupted for long periods to avoid interference with EK80 surveys
• Column-level documentation is absent; field semantics must be inferred after download
• Row count and data volume are unknown, which may limit suitability assessment
