RV Investigator Voyage IN2021_V03: Acoustic Doppler Current Profiler Data

Acoustic Doppler Current Profiler (ADCP) data collected during the RV Investigator voyage IN2021_V03 from Hobart to Brisbane between May 8 and June 3, 2021. The data were collected using RDI Ocean Surveyor 75kHz and 150kHz instruments operating in narrowband mode and processed using the Common Ocean Data Access System (CODAS). This quality-controlled dataset was archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.

Use Cases

• Analyzing ocean current velocity profiles based on ADCP transect data.
• Monitoring multi-year property transports of the East Australian Current based on the voyage's scientific objective.
• Calibrating or validating ocean circulation models based on in-situ ADCP measurements.
• Studying the vertical structure of currents based on data from instruments located approximately 8.0m below the water line.

Strengths

• Data was collected over a specific voyage period from May 8 to June 3, 2021.
• Two ADCP instruments (OS75 and OS150) were used and reportedly operated well without issues.
• Data was post-processed and quality-controlled using established systems (UHDAS, CODAS) and archived by CSIRO NCMI IDC.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• File formats listed are PNG and HTML, suggesting the primary download may be visualizations or reports rather than raw numerical data.
