RV Investigator IN2021_V03: East Australian Current ADCP Measurements, May-June 2021

May 8 to June 3, 2021, Acoustic Doppler Current Profiler (ADCP) data collected from the RV Investigator voyage IN2021_V03, monitoring the East Australian Current at 27 degrees South. The data were collected using OS75 and OS150 ADCPs in narrowband mode, processed with CODAS, and archived by CSIRO's National Collections and Marine Infrastructure. Transducers were located approximately 8.0 meters below the water line for the voyage's duration.

Use Cases

• Modeling ocean current velocity and direction based on ADCP transect data
• Analyzing temporal variability of the East Australian Current based on multi-year monitoring mentioned in the description
• Calibrating regional ocean circulation models based on quality-controlled, ship-collected current profiles
• Studying vertical current structure based on data from two different frequency ADCPs (75kHz and 150kHz)

Strengths

• Data collected over a defined voyage period from May 8 to June 3, 2021
• Uses two instrument types (OS75 and OS150 ADCPs) for all transects, with transducers at a known depth of approximately 8.0 meters
• Post-processed and quality-controlled using the Common Ocean Data Access System (CODAS)
• Archived by the authoritative CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre

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 ship voyage
