CARINA: North Atlantic Ocean Carbon and Hydrographic Profiles from 1989

CARINA/74DI19890612 includes chemical, physical, and profile data collected from the R/V DISCOVERY in the North Atlantic Ocean between June 12 and July 9, 1989. The dataset contains measurements of dissolved inorganic carbon, oxygen, nutrients, salinity, and temperature obtained using CTD and bottle instruments. Andrew J. Watson of the Plymouth Marine Laboratory collected these data as part of the CARINA synthesis project for biogeochemical investigations.

Use Cases

• Modeling ocean carbon uptake based on dissolved inorganic carbon and nutrient measurements.
• Analyzing water column structure and oceanographic conditions using CTD-derived temperature, salinity, and pressure profiles.
• Investigating nutrient cycling and primary production based on nitrate, phosphate, and silicate data.
• Calibrating and validating biogeochemical models using internally consistent, merged subsurface measurements.

Strengths

• Data is part of the CARINA international synthesis project, which produced a merged, internally consistent dataset for biogeochemical studies.
• Includes multiple key oceanographic variables: dissolved inorganic carbon, oxygen, nutrients, temperature, and salinity.
• Covers a specific cruise in the North Atlantic Ocean with a clear temporal range from 1989-06-12 to 1989-07-09.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to a single research cruise in 1989.
