RV Investigator Voyage IN2024_V05 Acoustic Doppler Current Profiler Data

Acoustic Doppler Current Profiler (ADCP) data collected from the RV Investigator voyage IN2024_V05 between November 13 and December 12, 2024. The 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. Three RDI Ocean Surveyor ADCPs (150kHz, 75kHz, 38kHz) were run in narrowband mode, though acquisition was interrupted during concurrent EK80 fisheries surveys.

Use Cases

• Calibrating ocean current models based on ADCP measurements
• Analyzing water column velocity profiles for the southeast marine ecosystem
• Studying interference patterns between acoustic survey instruments (ADCP and EK80)
• Investigating multi-year changes in marine ecosystems using time-series current data

Strengths

• Data were post-processed using the Common Ocean Data Access System (CODAS)
• Three distinct ADCP instruments (150kHz, 75kHz, 38kHz) were deployed
• The voyage spanned a defined period from November 13 to December 12, 2024

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• ADCP acquisition was not continuous due to interference with EK80 fisheries surveys
