Atlantic Ocean Carbon Chemistry and Hydrographic Profiles from 1997

CARINA/06MT19970707 cruise data includes dissolved inorganic carbon, alkalinity, and chlorofluorocarbons measured in the Davis Strait, Labrador Sea, and North Atlantic Ocean. Arne Körtzinger of GEOMAR and collaborators collected these discrete sample and profile observations using CTD and bottle instruments from July to August 1997. The dataset is part of the CARINA synthesis project for creating an internally consistent Atlantic Ocean biogeochemical dataset.

Use Cases

• Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and alkalinity measurements.
• Investigating water mass age and circulation using chlorofluorocarbon (CFC-11, CFC-12) tracers.
• Analyzing nutrient distributions and biogeochemical processes based on nitrate, phosphate, and silicate data.
• Studying ocean hydrography and water column structure using CTD-derived temperature, salinity, and pressure profiles.

Strengths

• Data is part of the CARINA international synthesis project, aimed at producing an internally consistent dataset for biogeochemical investigations.
• Includes 13 key chemical and physical variables, such as dissolved inorganic carbon, alkalinity, CFCs, and nutrients.
• Covers a specific transect in the North Atlantic Ocean, Davis Strait, and Labrador Sea during a defined cruise from July 7 to August 9, 1997.

Limitations

• Column-level documentation and sample data are unavailable, making field semantics and data structure uncertain before download.
• Row count and file size are unknown, which limits suitability assessment for large-scale analysis.
• The dataset's age means it represents a historical snapshot; contemporary conditions may differ.
