Over 10 chemical and physical variables, including dissolved inorganic carbon, alkalinity, and chlorofluorocarbon-11, were collected from discrete water samples and profiles. The data were gathered by researchers from the University of Bergen and the Bjerknes Center for Climate Research during a 1989 expedition aboard the STENA ARCTICA. This dataset is part of the CARINA synthesis project for biogeochemical investigations.
Use Cases
- Calculate ocean acidification parameters like pCO2 and pH using DISSOLVED INORGANIC CARBON and TOTAL ALKALINITY measurements.
- Study water mass age and circulation using CHLOROFLUOROCARBON-11 (CFC-11) as a tracer alongside SALINITY and Potential temperature.
- Model nutrient cycles by analyzing correlations between NITRATE, phosphate, and silicate concentrations.
- Investigate ocean ventilation and biological activity using DISSOLVED OXYGEN profiles with HYDROSTATIC PRESSURE.
- Calibrate or validate regional ocean models with in-situ profiles of WATER TEMPERATURE, SALINITY, and biogeochemical variables.
Strengths
- Includes over 10 key variables for carbon system and nutrient studies per observation.
- Data collected as part of the CARINA project, ensuring internal consistency for synthesis work.
- Provides discrete sample and profile data from a targeted Southern Ocean expedition.
Limitations
- Temporal coverage is limited to a single cruise over one month in 1989.
- Geographic coverage is restricted to the South Atlantic and Southern Oceans (>60°S) from that cruise.
- Sample size and row count are unknown, potentially limiting statistical power.
