RV Investigator Voyage IN2023_V07 ADCP Data

November 15 to December 20, 2023, the RV Investigator voyage IN2023_V07 collected Acoustic Doppler Current Profiler (ADCP) data south of Tasmania. The data were collected using RDI Ocean Surveyor OS150kHz and WH75kHz instruments, processed with the Common Ocean Data Access System (CODAS), and archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.

Use Cases

• Analyzing vertical current profiles based on ADCP data collected from extended drop keels.
• Studying smaller-scale ocean dynamics in a meander of the Antarctic Circumpolar Current based on the voyage's scientific objective.
• Validating ocean circulation models using quality-controlled, post-processed current velocity data.
• Investigating instrument performance and data collection methodologies for different ADCP modes (narrowband vs. broadband).

Strengths

• Data collection occurred over a defined 36-day voyage from November 15 to December 20, 2023.
• Post-processing and quality control were performed using the established Common Ocean Data Access System (CODAS).
• Transducers were located at a known, consistent depth of approximately 7.2 meters below the water line for the voyage duration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• The OS75 instrument was not operational, requiring the use of a substitute (WH75) system.
