RV Investigator Voyage IN2024_V02 Acoustic Doppler Current Profiler Data

Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2024_V02 between March 31, 2024 and April 19, 2024. The voyage, titled 'SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania,' departed from and returned to Hobart. Data were collected using the University of Hawaii Data Acquisition System (UHDAS) and post-processed using CODAS, then archived by CSIRO NCMI IDC.

Use Cases

• Modeling ocean current profiles based on ADCP measurements from the voyage.
• Analyzing temporal changes in water column dynamics during the 20-day voyage period.
• Studying instrument performance and interference patterns based on described operational events with the WH75 and EK80.
• Investigating the impact of keel depth (6m to 8m below water line) on acoustic data collection.

Strengths

• Data collected during a defined 20-day research voyage with specific departure and return dates.
• Post-processed using the documented Common Ocean Data Access System (CODAS).
• Includes detailed operational notes on instrument status and configuration (e.g., narrowband vs. broadband mode, keel depths).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description notes specific instrument issues (WH75 checksum errors, suspected water ingress) affecting data continuity.
