May 25 to June 6, 1994, this dataset contains discrete sample and profile measurements of dissolved inorganic carbon, alkalinity, nutrients, and physical seawater properties collected from the R/V Johan Hjort in the North Greenland and Norwegian Seas. It was gathered by researchers from the Commonwealth Scientific and Industrial Research Organization and the University of Bergen as part of the CARINA data synthesis project for biogeochemical investigations.
Use Cases
- Calculate ocean acidification parameters like pCO2 or pH from DISSOLVED INORGANIC CARBON and ALKALINITY measurements.
- Analyze nutrient utilization and biological productivity using NITRATE, PHOSPHATE, SILICATE, and OXYGEN - APPARENT UTILIZATION (AOU) profiles.
- Model water mass properties and circulation using SALINITY, WATER TEMPERATURE, Potential temperature (theta), and SIGMA-T data.
- Investigate carbon system variability with depth by joining DISSOLVED INORGANIC CARBON and ALKALINITY with HYDROSTATIC PRESSURE.
Strengths
- Includes 13 key biogeochemical and physical variables per sampling event.
- Data is part of the curated, internally consistent CARINA synthesis project for the Atlantic and Arctic Oceans.
Limitations
- Temporal coverage is limited to a single 13-day cruise in 1994.
- Geographic scope is restricted to two specific sea regions in the Arctic.
- Sample size and row count are unknown, potentially limiting statistical power.
