Chemical and physical oceanographic data were collected from the POLARSTERN research vessel during a cruise in the Arctic Ocean and North Greenland Sea from July to September 1987. The dataset includes measurements of dissolved inorganic carbon, chlorofluorocarbons, nutrients, oxygen isotopes, salinity, and temperature. Data were gathered by researchers from Gothenburg University and others as part of the CARINA synthesis project.
Use Cases
- Analyze dissolved inorganic carbon concentration trends against salinity and water temperature to study Arctic Ocean acidification.
- Model chlorofluorocarbon (CFC-11, CFC-12) distributions using hydrostatic pressure and potential temperature to trace ocean ventilation.
- Correlate nutrient levels (nitrate, phosphate, silicate) with dissolved oxygen measurements to assess biological productivity.
- Use tritium and delta oxygen-18 isotope data alongside salinity profiles to trace freshwater inputs and water mass origins.
Strengths
- Includes 15 distinct chemical and physical variables per sampling event.
- Data collected over a focused 2-month cruise period in 1987.
- Part of the CARINA international synthesis project for internal consistency.
Limitations
- Data is from a single cruise, limiting temporal and spatial generalization.
- Sample size and row count are unknown, potentially small for statistical modeling.
- Data is historical (1987) and may not reflect current ocean conditions.
