IN2024_V02: Acoustic Doppler Current Profiler Data from Southern Ocean Voyage

Southern Ocean southwest of Tasmania is the region for this Acoustic Doppler Current Profiler (ADCP) dataset from the RV Investigator voyage IN2024_V02. The data, collected between March 31 and April 19, 2024, measures ocean currents using RDI Ocean Surveyor instruments in narrowband and broadband modes. It was processed with the UHDAS and CODAS systems and archived by CSIRO's National Collections and Marine Infrastructure.

Use Cases

• Analyzing current velocity profiles based on ADCP measurements from drop keels.
• Studying signal interference patterns during concurrent EK80 surveying operations.
• Investigating instrument performance and error logging, such as the WH75 checksum errors.
• Calibrating or validating ocean circulation models with quality-controlled voyage data.
• Assessing mooring site conditions for the Southern Ocean Time Series (SOTS) program.

Strengths

• Data is quality-controlled and archived by a national research institution (CSIRO NCMI IDC).
• Specific instrument configurations and deployment depths (approx. 6m and 8m) are documented.
• Cross-platform presence on a government data portal indicates formal curation and importance.

Limitations

• Column names, row counts, and file sizes are unknown, limiting immediate analytical utility.
• Metadata completeness is low; license, author, and precise data structure are not provided.
• A specific instrument (WH75) experienced repeated failures, potentially creating data gaps.
