North Atlantic Ocean Carbon Chemistry Profiles from the CARINA Project, August 1998

Discrete chemical and physical oceanographic data collected from the JOHAN HJORT research vessel in the North Greenland and Norwegian Seas during August 1998. The dataset includes 19 variables such as dissolved inorganic carbon, alkalinity, pH, nutrients, chlorofluorocarbons, and dissolved oxygen, measured using CTD and bottle instruments. Data were collected by researchers from the Bjerknes Centre for Climate Research, Institute of Marine Research - Norway, and the University of Gothenburg as part of the CARINA international synthesis project.

Use Cases

• Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements.
• Studying anthropogenic tracer distribution based on chlorofluorocarbon (CFC-11, CFC-12, CFC-113) and carbon tetrachloride data.
• Investigating water mass ventilation and age using helium, tritium, and delta helium-3 isotopes.
• Analyzing nutrient cycling and primary production based on nitrate, nitrite, phosphate, and silicate concentrations.
• Calibrating biogeochemical models using internally consistent, merged data from the CARINA synthesis project.

Strengths

• Includes 19 distinct chemical and physical variables for a comprehensive biogeochemical profile.
• Data is part of the CARINA international synthesis project, which produced an internally consistent, merged dataset.
• Specific collection period from 1998-08-01 to 1998-08-23 provides a focused temporal snapshot.

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 modeling.
• Data is from a single cruise in 1998, limiting temporal and spatial generalizability.
