The Indian Ocean section P06S was surveyed by the R/V Marion Dufresne from January to March 1993. This dataset includes dissolved inorganic carbon, alkalinity, temperature, salinity, nutrients, chlorofluorocarbons, and delta C14 measurements from discrete samples and profiles. The data were collected by Alain Poisson of Universite Pierre et Marie Curie as part of the World Ocean Circulation Experiment.
Use Cases
- Modeling ocean carbon uptake based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing ocean circulation patterns based on hydrographic temperature and salinity profiles.
- Studying anthropogenic tracer distribution based on chlorofluorocarbon (CFC) data.
- Investigating nutrient cycling and biological processes based on nutrient concentration data.
- Calibrating or validating climate models using the comprehensive suite of physical and chemical variables.
Strengths
- Data is part of the major World Ocean Circulation Experiment (WOCE) program, which aimed to better understand the ocean's role in climate.
- Includes a multi-variable suite covering carbon chemistry (DIC, alkalinity), physical properties (temperature, salinity), and tracers (CFCs, delta C14).
- Collection period is precisely defined from 1993-01-23 to 1993-03-09.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 1993-03-09; freshness should be verified for contemporary applications.
- Row count is unknown, which may limit suitability assessment.
