November 1993 to December 1993 data includes dissolved inorganic carbon, chlorofluorocarbons, dissolved oxygen, nitrate, phosphate, silicate, salinity, and water temperature. The dataset was collected by E. Peter Jones and R.A. Clarke during the CARINA/18HU19931105 cruise in the North Atlantic Ocean.
Use Cases
- Analyze dissolved inorganic carbon concentration trends with salinity and water temperature to study ocean acidification.
- Use chlorofluorocarbon-11 and chlorofluorocarbon-12 measurements as tracers for ocean circulation and ventilation age calculations.
- Correlate nitrate, phosphate, and silicate levels with dissolved oxygen to investigate marine nutrient cycles and biogeochemical processes.
- Model potential temperature (theta) against hydrostatic pressure to understand the water column's thermal structure.
- Study the relationship between carbon tetrachloride and other chlorofluorocarbon species for tracing anthropogenic pollutant dispersion.
Strengths
- Data spans a specific 42-day cruise from 1993-11-05 to 1993-12-16.
- Includes 13 distinct chemical and physical variables, including multiple chlorofluorocarbon species.
- Part of the CARINA international synthesis project for internally consistent biogeochemical data.
Limitations
- Dataset is from a single cruise in 1993, providing only a snapshot with no longitudinal time series.
- Geographic coverage is limited to the specific track of the HUDSON vessel in the North Atlantic Ocean.
- Row count and sample density per variable are unknown, limiting statistical power assessments.
