Over 10 chemical and physical variables, including dissolved inorganic carbon and alkalinity, were measured from discrete water samples and CTD profiles. Data was collected by researchers from the University of Bergen during the CARINA/58AA19980308 cruise in March 1998. This dataset supports the CARINA synthesis project for creating an internally consistent ocean carbon data set.
Use Cases
- Calculate ocean acidification parameters like pCO2 and pH from the dissolved_inorganic_carbon and alkalinity measurements.
- Analyze nutrient distributions (nitrate, phosphate, silicate) relative to water_temperature and salinity to study biological productivity.
- Model carbon system dynamics by correlating dissolved_inorganic_carbon with potential_temperature and dissolved_oxygen across hydrostatic_pressure depths.
- Validate regional ocean carbon models using this discrete profile data as a ground truth reference for the 1998 period.
Strengths
- Includes over 10 key biogeochemical variables per observation, enabling multi-parameter analysis.
- Data is part of the curated CARINA international synthesis project, ensuring internal consistency.
- Provides discrete sample and high-resolution CTD profile data from a specific Arctic research cruise.
Limitations
- Temporal coverage is limited to a single 17-day cruise in March 1998, offering only a seasonal snapshot.
- Geographic scope is restricted to stations in the North Greenland Sea and Norwegian Sea.
- Sample size and total row count are unknown, potentially limiting statistical power.
