CARINA: North Atlantic Ocean Carbon and Water Chemistry Profiles from July-August 1998

From July 30 to August 21, 1998, this dataset contains discrete sample and profile observations of dissolved inorganic carbon, pH, alkalinity, and related water chemistry variables collected from the R/V HESPERIDES in the North Atlantic Ocean. The data were gathered using CTD and bottle instruments during cruise CARINA/29HE19980730 by researchers from CSIRO, IIM Vigo, and the Spanish Institute of Oceanography. It is part of the CARINA project, an international synthesis effort for biogeochemical investigations of the carbon system across the Atlantic, Arctic, and Southern Oceans.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and pH measurements.
• Analyzing nutrient cycles in marine ecosystems based on nitrate, phosphate, silicate, and ammonium data.
• Studying water mass properties and ocean circulation using potential temperature, salinity, and hydrostatic pressure profiles.
• Calibrating and validating biogeochemical ocean models using the internally consistent CARINA synthesis data.

Strengths

• Data collection occurred over a focused 23-day period in a specific region, providing a temporally and spatially coherent snapshot.
• Includes 12 key chemical and physical variables relevant to ocean carbon and nutrient studies, as listed in the description.
• Part of the CARINA international synthesis project, which aims to produce an internally consistent dataset for biogeochemical investigations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Description metadata is limited; actual data quality requires manual inspection after download.
