RV Investigator Voyage IN2024_V05 ADCP Data

November 13 to December 12, 2024, the RV Investigator collected Acoustic Doppler Current Profiler (ADCP) data during the SEA-MES Voyage 3 in the southeast marine ecosystem. Data were processed using the Common Ocean Data Access System (CODAS) and archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre. The dataset includes measurements from RDI Ocean Surveyor 150kHz, 75kHz, and 38kHz ADCPs run in narrowband mode.

Use Cases

• Analyzing ocean current profiles and variability based on ADCP measurements from three different frequencies.
• Calibrating acoustic survey instruments using the bottom-tracking data collected for an hour on the OS150nb.
• Studying the interaction between physical oceanography and fisheries ecosystems during the SEA-MES research voyage.
• Investigating the impact of instrument interference by comparing ADCP operational periods with EK80 survey times.

Strengths

• Data collected over a defined 30-day voyage period from November 13 to December 12, 2024.
• Post-processed using the documented Common Ocean Data Access System (CODAS) methodology.
• Includes measurements from three specific ADCP instruments (150kHz, 75kHz, 38kHz) providing multi-frequency current profiles.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• ADCP data acquisition was intermittent, as the instruments were turned off during extensive EK80 surveys to avoid interference.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
