Atlantic Ocean Carbon Chemistry Profiles from the CARINA Cruise, 1995

From April 19 to May 16, 1995, this dataset contains discrete sample and profile measurements of dissolved inorganic carbon, chlorofluorocarbons, oxygen, nutrients, and other variables from the Gulf of St. Lawrence and North Atlantic Ocean. The data were collected during cruise CARINA/18HU19950419 aboard the HUDSON using CTD and bottle instruments by researchers from BDR Research Ltd and the Bedford Institute of Oceanography. It is part of the CARINA international synthesis project for biogeochemical investigations of the carbon system.

Use Cases

• Modeling ocean carbon uptake and storage based on dissolved inorganic carbon (DIC) and chlorofluorocarbon (CFC) tracer data.
• Analyzing historical nutrient distributions (nitrate, phosphate, silicate) for biogeochemical studies.
• Investigating water mass properties and circulation using potential temperature, salinity, and dissolved oxygen profiles.
• Calibrating and validating ocean carbon system models with internally consistent, merged subsurface measurements.

Strengths

• Includes multiple key biogeochemical variables (DIC, CFCs, nutrients, oxygen) for a consistent analysis period.
• Data are part of the CARINA synthesis project, which aims to produce an internally consistent, merged dataset.
• Measurements were collected using standard oceanographic instruments (CTD and bottle) during a dedicated research cruise.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• The dataset's geographic coverage is limited to a specific cruise track in 1995.
