North Atlantic Ocean Carbon and Hydrographic Measurements from 1994

Chemical and physical profile data collected from the METEOR research vessel in the North Atlantic Ocean during October and November 1994. The dataset includes measurements for dissolved inorganic carbon, alkalinity, chlorofluorocarbons, nutrients, and hydrographic variables, collected as part of the CARINA and WOCE A02 projects. The broader CARINA project produced a merged dataset from approximately 23,000 stations across 94 WOCE cruises between 1990 and 1998.

Use Cases

• Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and alkalinity measurements.
• Analyzing historical chlorofluorocarbon (CFC) distributions as tracers for ocean circulation.
• Studying nutrient cycles (nitrate, phosphate, silicate) in relation to biological activity.
• Investigating water mass properties and circulation using hydrographic data like salinity and potential temperature.

Strengths

• Data is part of the CARINA synthesis project, an international effort to create an internally consistent dataset for biogeochemical investigations.
• Includes multiple key carbon system variables (DIC, TA, CFCs) alongside standard hydrographic and nutrient measurements.
• Associated with major oceanographic programs (WOCE and CARINA), suggesting standardized collection protocols.

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 month in 1994, representing a specific temporal snapshot.
