RV Investigator Voyage IN2024_V05 ADCP Data

Southeast Australian marine ecosystem data collected by the RV Investigator between November 13 and December 12, 2024. Acoustic Doppler Current Profiler (ADCP) data were gathered using three RDI Ocean Surveyor instruments and processed by CSIRO's National Collections and Marine Infrastructure Information and Data Centre. The data likely contains ocean current profiles, though collection was intermittent to avoid interference with fisheries surveys.

Use Cases

• Modeling ocean current profiles based on ADCP measurements from the voyage.
• Analyzing temporal gaps in current data based on periods when the ADCP was turned off for EK80 surveys.
• Calibrating ADCP instruments based on the one hour of bottom tracking performed.
• Studying the southeast Australian marine ecosystem change over 25 years, as referenced in the voyage title.

Strengths

• Data was collected over a defined 30-day voyage from November 13 to December 12, 2024.
• Processed and quality-controlled using the Common Ocean Data Access System (CODAS) and archived by CSIRO.
• Includes data from three specific ADCP instruments (150kHz, 75kHz, 38kHz) run in narrowband mode.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• ADCP data acquisition was not continuous, with long periods turned off during EK80 use.
