CARINA: North Atlantic Ocean Carbon Chemistry Profiles from May-June 2001

Discrete chemical and physical measurements from the HAAKON MOSBY research vessel during cruise TRACTOR 13 from 2001-05-27 to 2001-06 19. The data include dissolved inorganic carbon, alkalinity, chlorofluorocarbons, sulfur hexafluoride, dissolved oxygen, temperature, and salinity, collected using CTD and bottle instruments. Abdirahman M. Omar, Truls Johannessen, and Are Olsen collected these data as part of the international CARINA synthesis project for biogeochemical investigations.

Use Cases

• Calibrating ocean carbon cycle models based on dissolved inorganic carbon and alkalinity measurements.
• Tracing water mass age and circulation based on chlorofluorocarbon (CFC-11, CFC-12) and sulfur hexafluoride (SF6) data.
• Assessing ocean acidification trends based on carbonate system parameters.
• Validating regional hydrographic models based on CTD-derived temperature, salinity, and pressure profiles.

Strengths

• Data is part of the CARINA international synthesis project, which produced a merged, internally consistent dataset for the Atlantic and Arctic Oceans.
• Includes multiple key carbon system and tracer variables (DIC, Alkalinity, CFCs, SF6, Oxygen) for a single research cruise.
• Collection period is precisely defined from 2001-05-27 to 2001-06-19.

Limitations

• Row count and file size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic and temporal bias inherent to a single cruise in the North Atlantic.
