North Greenland Sea and Norwegian Sea chemical and physical oceanographic data collected during August 1998 aboard the JOHAN HJORT. The dataset includes dissolved inorganic carbon, alkalinity, chlorofluorocarbons, nutrients, and temperature profiles from discrete bottle and CTD samples. It was collected by researchers from Gothenburg University and the University of Bergen as part of the CARINA (CARbon dioxide IN the Atlantic Ocean) international synthesis project.
Use Cases
- Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing chlorofluorocarbon (CFC) distributions as tracers for ocean circulation and ventilation.
- Studying nutrient (nitrate, phosphate, silicate) cycles in relation to primary productivity.
- Investigating the relationship between hydrostatic pressure, temperature, salinity, and chemical properties.
Strengths
- Data covers a specific cruise from 1998-08-01 to 1998-08-23, providing a focused temporal snapshot.
- Includes 18 distinct chemical and physical variables, such as ALKALINITY, CFCs, DISSOLVED OXYGEN, and NITRATE.
- Part of the CARINA international synthesis project aimed at producing an internally consistent data set for biogeochemical investigations.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Last updated 1998-08-23; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
