CARINA: North Atlantic Ocean Carbon and Hydrographic Profiles from 1993

CARINA/18HU19930405 is a dataset of chemical and physical oceanographic measurements collected from the RV Hudson in the North Atlantic Ocean between April 5 and May 14, 1993. The data include dissolved inorganic carbon, oxygen, nutrients, temperature, and salinity, collected using CTD and bottle instruments by researchers from the Bedford Institute of Oceanography. This dataset is part of the international CARINA synthesis project for biogeochemical investigations of the carbon system.

Use Cases

• Modeling ocean carbon uptake based on dissolved inorganic carbon measurements.
• Analyzing water mass properties and circulation using temperature, salinity, and pressure profiles.
• Studying nutrient distributions and ocean productivity based on nitrate, phosphate, and silicate data.
• Calibrating or validating biogeochemical ocean models using the internally consistent CARINA synthesis.

Strengths

• Data is part of the CARINA international synthesis project, which produced an internally consistent dataset for carbon system studies.
• Includes multiple key biogeochemical variables (DIC, oxygen, nutrients) alongside core physical parameters.
• Covers a specific 40-day research cruise in the North Atlantic Ocean, providing 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.
• Data is from a single cruise in 1993; temporal and geographic scope is limited.
