RV Investigator Voyage IN2023_V07 ADCP Data

Acoustic Doppler Current Profiler data from the RV Investigator voyage IN2023_V07, focused on smaller scales of the Antarctic Circumpolar Current south of Tasmania. The data were collected between November 15 and December 20, 2023, using RDI Ocean Surveyor instruments and processed by CSIRO's National Collections and Marine Infrastructure. One instrument was run in narrowband mode and another in broadband mode, with transducers located approximately 7.2 meters below the water line.

Use Cases

• Analyzing vertical current profiles based on ADCP data collected from drop keels.
• Studying the Antarctic Circumpolar Current's smaller-scale variability based on the voyage's scientific focus.
• Validating ocean circulation models using quality-controlled current measurements processed with CODAS.
• Investigating instrument performance by comparing data from the WH75kHz broadband and OS150kHz narrowband systems.

Strengths

• Data were collected over a 36-day voyage from November 15 to December 20, 2023.
• Post-processed using the Common Ocean Data Access System (CODAS), indicating a standardized quality control procedure.
• Transducer depth is precisely documented as approximately 7.2 meters below the water line.
• Archived by CSIRO National Collections and Marine Infrastructure, suggesting institutional stewardship.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analyses.
• The OS75 instrument was not operational, reducing the potential multi-frequency observational suite.
