RV Investigator Voyage IN2024_V02 ADCP Data

Acoustic Doppler Current Profiler (ADCP) data were collected by the Marine National Facility RV Investigator during voyage IN2024_V02, titled 'SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania.' The voyage occurred between March 31, 2024 and April 19, 2024, departing from and returning to Hobart. Data were processed and archived by CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).

Use Cases

• Analyzing ocean current velocity profiles based on ADCP measurements mentioned in the description
• Studying temporal variability of currents during the SOTS mooring deployment and maintenance voyage
• Investigating instrument performance and data gaps based on the reported WH75 logging issues and EK80 survey interference
• Modeling water column dynamics southwest of Tasmania using data from instruments located on drop keels 6-8 meters below the water line

Strengths

• Data were collected during a dedicated 20-day research voyage (March 31 to April 19, 2024) for climate and carbon cycle studies.
• Post-processed using the Common Ocean Data Access System (CODAS), suggesting a standardized quality control workflow.
• Instrument deployment details are specified, including transducer depths of approximately 6m and 8m below the water line.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data collection experienced interruptions; the WH75 instrument stopped logging due to suspected water ingress, creating potential gaps.
