Over 20 chemical and physical variables, including dissolved inorganic carbon, alkalinity, and chlorophyll A, were collected from the North Greenland Sea during a 1992 summer cruise. The data was gathered by J. Deming of the University of Washington using CTD and bottle instruments aboard the USCGC POLAR SEA. This dataset is part of the CARINA international synthesis project for biogeochemical investigations.
Use Cases
- Modeling ocean acidification by analyzing trends between dissolved inorganic carbon, alkalinity, salinity, and potential temperature.
- Studying nutrient dynamics and primary productivity using nitrate, phosphate, silicate, and chlorophyll A measurements.
- Investigating water mass age and circulation with tracer data like tritium, helium, and delta helium-3.
- Assessing particulate organic matter flux through particulate organic carbon and particulate organic nitrogen columns.
Strengths
- Data includes over 20 distinct biogeochemical variables per observation.
- Measurements are part of the curated, internally consistent CARINA synthesis project.
Limitations
- Dataset is temporally limited to a single 31-day cruise in July-August 1992.
- Geographic scope is confined to the North Greenland Sea, limiting broader regional analysis.
- Sample size and row count are unknown, which may affect statistical power.
