RV Investigator Voyage IN2021_V03 ADCP Data

Acoustic Doppler Current Profiler data from a 27-day voyage monitoring the East Australian Current. The CSIRO National Collections and Marine Infrastructure processed the data collected by the RV Investigator between Hobart and Brisbane in May-June 2021. Both OS75 and OS150 ADCPs operated in narrowband mode, with transducers located approximately 8.0m below the water line.

Use Cases

• Modeling the East Australian Current's transport properties based on the voyage's monitoring objective
• Analyzing vertical current profiles based on data from dual-frequency (75kHz and 150kHz) ADCPs
• Studying temporal variability of ocean currents along a transect based on the time-series nature of the voyage data
• Calibrating or validating regional ocean circulation models based on quality-controlled, in-situ ADCP measurements

Strengths

• Data is quality-controlled and archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre
• Uses two calibrated instruments (RDI Ocean Surveyor 75kHz and 150kHz ADCPs) for cross-verification
• Voyage duration of 27 days (May 8 to June 3, 2021) provides a continuous time series
• Specific transducer depth is documented as approximately 8.0m below the water line

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic/temporal bias inherent to the single voyage and transect
