RV Investigator Voyage IN2023_V07 ADCP Data

Acoustic Doppler Current Profiler (ADCP) data collected from the RV Investigator voyage IN2023_V07 between November 15, 2023 and December 20, 2023. The data were collected using University of Hawaii Data Acquisition System (UHDAS) and post-processed using the Common Ocean Data Access System (CODAS), then archived by CSIRO National Collections and Marine Infrastructure. The voyage focused on the smaller scales of the Antarctic Circumpolar Current in a meander south of Tasmania.

Use Cases

• Analyze ocean current velocity profiles based on ADCP measurements.
• Study the structure of the Antarctic Circumpolar Current based on data collected south of Tasmania.
• Validate or calibrate ocean circulation models based on in-situ current data.
• Investigate the performance of different ADCP instruments (OS150kHz, WH75kHz) based on the voyage's technical setup.

Strengths

• Data collected over a 35-day voyage, providing continuous temporal coverage.
• Post-processed using the Common Ocean Data Access System (CODAS), suggesting standardized quality control.
• Transducers were located approximately 7.2m below the water line, a known and consistent measurement depth.

Limitations

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