CARINA Iceland Sea: Ocean Carbon and Biogeochemical Time Series

NCEI Accession 0157294 contains chemical, physical, and profile data from the North Greenland Sea collected between 1985-02-22 and 2013-11-26. The dataset includes measurements of dissolved inorganic carbon, dissolved oxygen, nitrate, phosphate, silicate, salinity, water temperature, and carbon dioxide partial pressure. It is part of the CARINA synthesis project for biogeochemical investigations, particularly studies of the ocean carbon system.

Use Cases

• Analyzing long-term trends in ocean acidification based on dissolved inorganic carbon and pCO2 measurements.
• Modeling carbon system dynamics using concurrent measurements of DIC, temperature, and salinity.
• Investigating nutrient cycles and their relationship to carbon uptake using nitrate, phosphate, and silicate data.
• Calibrating and validating ocean biogeochemical models with internally consistent, merged profile data.

Strengths

• Provides a 28-year time series of ocean measurements from 1985 to 2013.
• Includes a merged, internally consistent dataset synthesized by the international CARINA project.
• Contains concurrent measurements of multiple key biogeochemical variables (DIC, nutrients, oxygen, pCO2).

Limitations

• Column names and exact data structure are not specified in the available metadata.
• The dataset size and row count are unknown.
• There is a conflict in the 'last updated' date between platforms (2013-11-26 vs. 2026-03-05).
