December 1997 to February 1998 data collection includes dissolved inorganic carbon, alkalinity, pH, chlorofluorocarbons, sulfur hexafluoride, dissolved oxygen, temperature, and salinity. Measurements were taken by researchers from the Commonwealth Scientific and Industrial Research Organization during the CARINA/91AA19971204 cruise aboard the S. A. AGULHAS in the South Atlantic Ocean.
Use Cases
- Estimate anthropogenic carbon inventory using DISSOLVED INORGANIC CARBON, ALKALINITY, and transient tracer data like CFC-11, CFC-12, and SF6.
- Calculate ocean acidification parameters like carbonate saturation state from DISSOLVED INORGANIC CARBON, pH, ALKALINITY, SALINITY, and WATER TEMPERATURE.
- Track water mass age and ventilation rates by analyzing CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-12 (CFC-12), and SULFUR HEXAFLUORIDE (SF6) concentrations.
- Investigate physical oceanographic properties using vertical profiles of Potential temperature (theta), SALINITY, DISSOLVED OXYGEN, and HYDROSTATIC PRESSURE from CTD casts.
Strengths
- Includes 14 distinct chemical and physical variables for comprehensive carbon system analysis.
- Data is part of the CARINA synthesis project, ensuring internal consistency for biogeochemical investigations.
Limitations
- Temporal coverage is limited to a single two-month cruise from late 1997 to early 1998.
- Geographic coverage is restricted to the specific cruise track of the S. A. AGULHAS in the South Atlantic Ocean.
- Sample size and row count are unknown, limiting assessment of statistical robustness.
