CARINA: Ocean Carbon and Hydrographic Data from the North Atlantic and Arctic, 1997

Discrete sample and profile data collected from the JOHAN HJORT research vessel in the North Greenland Sea and Norwegian Sea from 1997-04-14 to 1997-05-22. The data include dissolved inorganic carbon, pH, alkalinity, CFCs, nutrients, and hydrographic variables, collected using CTD and bottle instruments. It was collected by Francisco Rey of the Institute of Marine Research - Norway and Leif G. Anderson of the University of Gothenburg as part of the CARINA data synthesis project.

Use Cases

• Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and alkalinity measurements.
• Studying ocean ventilation and water mass age using chlorofluorocarbon (CFC-11, CFC-12, CFC-113) and tracer (Helium, Tritium) data.
• Investigating nutrient cycling and primary production limitations based on nitrate, phosphate, and silicate concentrations.
• Calibrating and validating regional ocean biogeochemical models using internally consistent hydrographic and chemical profiles.

Strengths

• Data is part of the CARINA synthesis project, which produced a merged internally consistent dataset for biogeochemical investigations.
• Includes over 15 measured variables relevant to carbon system and ocean circulation studies.
• Covers a specific cruise in the North Greenland and Norwegian Seas during April-May 1997.

Limitations

• Column-level documentation and sample data are unavailable, requiring manual inspection after download.
• Row count and dataset size are unknown, which may limit suitability assessment for large-scale analyses.
• Data reflects a specific geographic and temporal snapshot, which may limit generalizability.
