RV Investigator Voyage IN2021_V03: ADCP Ocean Current Data from East Australian Coast

Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2021_V03, titled 'Integrated Marine Observing System: monitoring of East Australian Current property transports at 27 degrees South (multi-year).' The voyage took place from Hobart to Brisbane between May 8 and June 3, 2021. Data were collected using University of Hawaii and CODAS systems, processed by CSIRO NCMI IDC.

Use Cases

• Modeling ocean current transport properties based on the multi-year monitoring mission described.
• Calibrating ADCP instrument readings based on the documented use of OS75 and OS150 ADCPs in narrowband mode.
• Analyzing vertical current profiles based on the known transducer depth of approximately 8.0 meters below the water line.
• Studying temporal changes in coastal currents based on the time-series data collected during the May-June 2021 voyage.

Strengths

• Data is quality-controlled and archived by CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).
• Specific instrument configuration details are provided, including the use of both OS75 and OS150 ADCPs and a known transducer depth of ~8.0m.
• Voyage has precise temporal coverage from May 8 to June 3, 2021, and a defined route from Hobart to Brisbane.

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 a single voyage along the East Australian coast.
