Dissolved and Particulate Calcium Measurements from RV Investigator Voyage IN2020_V08 (SOL

Dissolved and particulate calcium measurements were collected during the RV Investigator voyage IN2020_V08 (SOLACE) from 4 December 2020 to 15 January 2021. The dataset includes total alkalinity and supporting hydrographic and nutrient data from the Australian sector of the Southern Ocean. It was created by the CSIRO Marlin Data Catalogue to investigate calcium carbonate cycling.

Use Cases

• Quantify calcium carbonate production and dissolution rates based on dissolved and particulate calcium concentrations.
• Evaluate dissolved calcium as a tracer for carbon sequestration based on the dataset's stated purpose.
• Analyze spatial patterns in marine chemistry at the Southern Ocean Time Series site and polar bloom sites.
• Model ocean alkalinity and carbon cycling using paired measurements of total alkalinity and hydrographic data.

Strengths

• Data collection occurred during a defined research voyage from 4 December 2020 to 15 January 2021.
• Measurements target specific, scientifically significant sites including the Southern Ocean Time Series (SOTS) and two polar bloom sites.
• Dataset integrates multiple measurement types including calcium concentrations, total alkalinity, and hydrographic data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal bias inherent to data_gov_au.
