1992 data from the South Pacific Ocean contains discrete measurements of dissolved inorganic carbon, chlorofluorocarbons, nutrients, and physical properties like temperature and salinity. The dataset was collected during a 15-day cruise aboard the R/V Knorr by researchers from multiple U.S. institutions. It supports the PACIFICA and WOCE P14C projects for studying ocean interior carbon cycles.
Use Cases
- Estimate anthropogenic carbon storage using DISSOLVED INORGANIC CARBON and CFC-11/CFC-12 tracer data.
- Analyze water mass age and circulation pathways with DELTA HELIUM-3, Tritium, and HELIUM measurements.
- Model nutrient cycles and biological productivity using NITRATE, PHOSPHATE, and SILICATE concentrations.
- Calibrate ocean models by comparing in-situ POTENTIAL TEMPERATURE, SALINITY, and WATER DENSITY profiles.
- Study carbon isotope systematics and ocean-atmosphere exchange using DELTA CARBON-13 and DELTA CARBON-14 data.
Strengths
- Includes 19 distinct chemical, physical, and isotopic variables per observation.
- Data collected during a focused 15-day research cruise ensuring temporal consistency.
- Supports two major international oceanographic programs: WOCE and PACIFICA.
Limitations
- Temporal coverage is limited to a single cruise in September 1992.
- Geographic scope is confined to the specific track of the R/V Knorr in the South Pacific.
- Sample size and spatial resolution are constrained by discrete bottle sampling methods.
