RV Investigator Voyage IN2024_V05 Acoustic Doppler Current Profiler Data

Acoustic Doppler Current Profiler (ADCP) data were collected during the RV Investigator voyage IN2024_V05 from November 13 to December 12, 2024. The data were processed using the Common Ocean Data Access System (CODAS) and archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre. ADCP instruments were run in narrowband mode, though data acquisition was intermittent to avoid interference with concurrent EK80 fisheries surveys.

Use Cases

• Calibrating acoustic current profilers based on the hour of bottom tracking data mentioned
• Analyzing ocean current patterns during a specific voyage period based on the time-series nature of ADCP data
• Studying interference between acoustic survey instruments based on the description of ADCP being turned off during EK80 operations

Strengths

• Data were post-processed using the documented Common Ocean Data Access System (CODAS)
• Specific voyage dates (November 13, 2024 to December 12, 2024) and departure/return port (Hobart) are provided
• Instrument configurations (narrowband mode, internal triggering, keel depth) are documented

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• ADCP data acquisition was not continuous, as instruments were turned off during EK80 surveys
