North Atlantic Ocean Carbon Chemistry Profiles from the CARINA Project, 1995

From April 27 to May 23, 1995, chemical and physical oceanographic data were collected from the North Greenland Sea and Norwegian Sea during cruise CARINA/58JH19950427. The dataset includes measurements of dissolved inorganic carbon, alkalinity, dissolved oxygen, nutrients, salinity, and temperature from discrete bottle samples and CTD profiles. Data were collected by researchers from the Bjerknes Centre for Climate Research, Institute of Marine Research - Norway, and the University of Bergen as part of the CARINA data synthesis project.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and alkalinity measurements.
• Analyzing nutrient distributions and their relationship to biological activity based on nitrate, phosphate, and silicate data.
• Studying water mass properties and circulation using salinity, temperature, and hydrostatic pressure profiles.
• Investigating dissolved oxygen variability and its link to biological and physical processes.

Strengths

• Data is part of the CARINA project, an international effort to produce a merged, internally consistent dataset for biogeochemical investigations.
• Includes multiple core variables for carbon system studies, such as dissolved inorganic carbon, alkalinity, and nutrients.
• Covers a specific temporal and geographic scope: a 27-day cruise in the North Greenland and Norwegian Seas.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single cruise in 1995; temporal and spatial coverage is limited.
