Arctic Ocean Carbon and Hydrographic Data from the CARINA Project, 1994

Chemical and physical oceanographic data collected from the LOUIS S. ST. LAURENT in the Arctic Ocean, Chukchi Sea, and North Greenland Sea from 1994-07-24 to 1994 09-01. The dataset includes measurements of dissolved inorganic carbon, alkalinity, chlorofluorocarbons, nutrients, dissolved oxygen, temperature, and salinity. Data were collected by researchers from the Bedford Institute of Oceanography, Fisheries and Oceans Canada, Scripps Institution of Oceanography, and the University of Washington as part of the CARINA synthesis project.

Use Cases

• Modeling ocean acidification and carbon uptake based on dissolved inorganic carbon and alkalinity measurements.
• Studying Arctic water mass circulation and ventilation using chlorofluorocarbon (CFC-11, CFC-12, CFC-113) tracer data.
• Analyzing nutrient dynamics and biological productivity based on nitrate, nitrite, phosphate, and silicate concentrations.
• Investigating hydrographic properties and water column structure using CTD-derived temperature, salinity, and pressure profiles.

Strengths

• Data collected by multiple authoritative institutions including Bedford Institute of Oceanography and Scripps Institution of Oceanography.
• Includes 15+ measured variables relevant for carbon system and biogeochemical studies.
• Part of the CARINA project, an international effort to produce a merged, internally consistent dataset for biogeochemical investigations.

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 1994; temporal coverage is limited.
