CARINA: North Atlantic Ocean Carbon and Chemistry Profiles, March-April 1992

From March 16 to April 9, 1992, chemical and physical oceanographic data were collected from the R/V METEOR in the North Atlantic Ocean. The dataset includes measurements of dissolved inorganic carbon, alkalinity, nutrients, oxygen, temperature, and salinity from discrete bottle samples and CTD profiles. It was collected by researchers from the University of Hamburg as part of the CARINA (CARbon dioxide IN the Atlantic Ocean) international synthesis project.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and alkalinity measurements.
• Analyzing nutrient cycling and ocean productivity based on nitrate, phosphate, silicate, and ammonium data.
• Studying water mass properties and circulation based on concurrent temperature, salinity, and hydrostatic pressure profiles.
• Calibrating and validating biogeochemical ocean models using this internally consistent, quality-controlled dataset.

Strengths

• Data is part of the CARINA international synthesis project, which produced a merged, internally consistent dataset for biogeochemical investigations.
• Includes a core suite of 12 chemical and physical variables relevant to carbon system studies.
• Covers a specific research cruise (06MT19920316) with clear temporal (1992-03-16 to 1992-04-09) and spatial (North Atlantic Ocean) boundaries.

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 ML tasks.
• Data is from a single cruise in 1992, which may limit temporal generalizability.
