North Atlantic Ocean Carbon Chemistry Profiles from the CARINA Project, 1997

CARINA/74D19970807 data includes dissolved inorganic carbon, pH, alkalinity, temperature, salinity, and other variables collected from discrete sample and profile observations using CTD and bottle instruments aboard the DISCOVERY in the North Atlantic Ocean from 1997-08-07 to 1997-09 17. The dataset was collected by Iris S. Aristegui, Sheldon Bacon, and Marta Álvarez as part of the CARINA and WOCE A25 projects. CARINA is an international synthesis project producing a merged, internally consistent dataset for biogeochemical investigations, originally focused on the North Atlantic.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and pH measurements.
• Studying biogeochemical cycles and nutrient distributions based on nitrate, phosphate, and silicate data.
• Analyzing water mass properties and circulation based on salinity, temperature, and chlorofluorocarbon (CFC) tracers.
• Investigating phytoplankton biomass dynamics based on chlorophyll a and phaeophytin concentrations.

Strengths

• Data is part of the CARINA synthesis project, which aims to produce an internally consistent, merged dataset for biogeochemical investigations.
• Includes 15 measured variables such as alkalinity, dissolved oxygen, and multiple nutrients, providing a multi-parameter view.
• Collected during a dedicated research cruise (CARINA/74D19970807) with specified instruments (CTD, bottle).

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 is from a single cruise in 1997, which may limit temporal generalizability.
