North Atlantic Ocean Carbon and Hydrographic Profiles from 1997

North Atlantic Ocean chemical and physical data collected from the METEOR research vessel between May 15 and June 6, 1997. The dataset includes dissolved inorganic carbon, alkalinity, nutrients, chlorofluorocarbons, and hydrographic variables from discrete bottle and CTD profile samples. It was collected by researchers from GEOMAR and other German institutions as part of the CARINA and WOCE AR12/AR24 projects.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and alkalinity measurements.
• Studying ocean circulation and water mass age using chlorofluorocarbon (CFC-11, CFC-12) tracer data.
• Analyzing nutrient distributions and biogeochemical cycles based on nitrate, phosphate, and silicate concentrations.
• Calibrating or validating oceanographic models with hydrographic profile data including salinity, temperature, and pressure.

Strengths

• Data is part of the CARINA international synthesis project, which produced a merged, internally consistent dataset for biogeochemical investigations.
• Includes multiple key variables for carbon system studies, specifically dissolved inorganic carbon and alkalinity.
• Covers a specific transect in the North Atlantic Ocean during a defined period (1997-05 15 to 1997-06-06).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data is from a single cruise in 1997; temporal and geographic scope is limited.
