CARINA: North Atlantic Ocean Carbon and Hydrographic Profiles from 1994

Chemical and physical profile data collected from the R/V Hudson in the North Atlantic Ocean from October 12 to November 10, 1994. E. Peter Jones and R. Allyn Clarke of the Bedford Institute of Oceanography gathered these measurements using CTD and bottle instruments for the CARINA data synthesis project. The dataset includes dissolved inorganic carbon, chlorofluorocarbons, dissolved oxygen, nutrients, temperature, and salinity.

Use Cases

• Modeling ocean carbon uptake and storage based on dissolved inorganic carbon (DIC) measurements
• Studying historical ocean ventilation and water mass age using chlorofluorocarbon (CFC-11, CFC-12, CFC-113) tracers
• Analyzing nutrient distributions and biogeochemical cycles based on nitrate, phosphate, and silicate data
• Investigating physical oceanographic properties and water column structure using CTD-derived temperature, salinity, and pressure profiles

Strengths

• Data collected during a dedicated 30-day oceanographic cruise in the North Atlantic Ocean
• Includes 13 distinct chemical and physical variables relevant to carbon cycle studies
• Part of the international CARINA synthesis project, which aims for internal consistency

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, limiting temporal and spatial generalizability
