North Atlantic Ocean Carbon System Measurements from CARINA Cruise, 1992

CARINA/58JH19920712 data includes chemical, physical, and profile measurements collected from the JOHAN HJORT research vessel in the North Atlantic Ocean, North Greenland Sea, and Norwegian Sea from July 12 to July 28, 1992. The dataset contains variables such as partial pressure of carbon dioxide, dissolved inorganic carbon, oxygen, nutrients, salinity, and temperature, collected using CTD and bottle instruments. Jón Ólafsson of the Icelandic Marine Research Institute and Johan Blindheim of the Institute of Marine Research - Norway collected these data as part of the CARINA and WOCE AR18b projects.

Use Cases

• Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and pCO2 measurements.
• Analyzing nutrient cycles in polar seas based on nitrate, phosphate, and silicate data.
• Studying water mass properties and circulation based on salinity, temperature, and oxygen profiles.
• Calibrating and validating global carbon cycle models based on the CARINA project's internally consistent dataset.

Strengths

• Data is part of the CARINA international synthesis project, which produced a merged internally consistent dataset for biogeochemical investigations.
• Includes multiple key carbon system and physical oceanography variables (13 are listed) from a single research cruise.
• Specific temporal coverage from 1992-07-12 to 1992-07-28 and geographic coverage in the North Atlantic, North Greenland Sea, and Norwegian Sea are documented.

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.
• Data may reflect temporal bias inherent to a single cruise in July 1992.
