North Atlantic Ocean data includes dissolved inorganic carbon, dissolved oxygen, nitrate, phosphate, silicate, salinity, and water temperature. Measurements were collected from discrete samples and profiles during a July 1990 cruise by researchers from the Commonwealth Scientific and Industrial Research Organization. This dataset is part of the CARINA synthesis project for biogeochemical investigations.
Use Cases
- Analyze dissolved inorganic carbon concentrations alongside salinity and temperature to study carbon sequestration.
- Model nitrate, phosphate, and silicate distributions to assess nutrient cycling in the North Atlantic.
- Correlate dissolved oxygen levels with hydrostatic pressure and temperature to examine ocean ventilation.
- Use tritium measurements as a tracer for water mass age and mixing processes.
- Calculate potential temperature (theta) from water temperature and salinity for thermodynamic analysis.
Strengths
- Data includes 11 key chemical and physical variables for biogeochemical analysis.
- Part of the CARINA project, an international effort producing a merged, internally consistent data set.
Limitations
- Temporal coverage is limited to a single 12-day cruise in July 1990.
- Geographic scope is restricted to the North Atlantic Ocean during this specific cruise.
- Affiliation of one contributor (H.M. van Aken) is unknown, affecting provenance clarity.
