Southern Ocean Carbon and Water Chemistry Profiles from 1989

Discrete water sample and profile data collected aboard the STENA ARCTICA in the South Atlantic and Southern Oceans from February 14 to March 17, 1989. The dataset includes measurements of dissolved inorganic carbon, alkalinity, chlorofluorocarbons, oxygen, nutrients, temperature, and salinity. Data were collected by Leif G. Anderson of the University of Gothenburg as part of the CARINA synthesis project for biogeochemical investigations.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and alkalinity measurements.
• Studying deep water formation and circulation patterns based on chlorofluorocarbon (CFC-11) tracer data.
• Analyzing nutrient distributions and their relationship to biological productivity based on nitrate, phosphate, and silicate data.
• Calibrating and validating biogeochemical ocean models using a consistent, quality-controlled profile dataset.

Strengths

• Data is part of the CARINA synthesis project, which produced a merged, internally consistent dataset for biogeochemical investigations.
• Includes multiple core variables for carbon cycle studies: dissolved inorganic carbon, total alkalinity, oxygen, and CFC-11.
• Covers a specific cruise in the Southern Ocean (>60 degrees South) during a defined period in 1989.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect temporal bias, being from a single cruise over one month in 1989.
