NODC Accession 0113562 contains discrete chemical and physical oceanographic measurements from the North Greenland and Norwegian Seas. The dataset includes 18 variables such as dissolved inorganic carbon, alkalinity, chlorofluorocarbons, and nutrients, collected via CTD and bottle sampling during the CARINA/58JH19951108 cruise from November 8 to 26, 1995. Data were collected by researchers from the Commonwealth Scientific and Industrial Research Organization and the University of Bergen.
Use Cases
- Calculate ocean acidification parameters like pCO2 and pH using dissolved inorganic carbon and alkalinity measurements.
- Trace water mass age and circulation patterns by analyzing Chlorofluorocarbon-11 (CFC-11), CFC-12, and Helium isotope data.
- Model nutrient cycles and primary production constraints from Nitrate, Phosphate, and Silicate concentration profiles.
- Calibrate ocean carbon models by correlating potential temperature (theta) and salinity with dissolved inorganic carbon observations.
- Study anthropogenic tracer penetration using time-series of Carbon tetrachloride (CCL4) and methyl chloroform (MC) measurements.
Strengths
- Includes 18 distinct chemical and physical variables per sampling location.
- Data collected over a 19-day cruise in November 1995, providing a temporal snapshot.
- Part of the CARINA international synthesis project for internally consistent biogeochemical data.
Limitations
- Single cruise dataset from 1995, limiting temporal analysis and modern comparisons.
- Geographic coverage is restricted to the North Greenland Sea and Norwegian Sea.
- Sample size is unknown, potentially limiting statistical power for some analyses.
