Indian Ocean and Savu Sea data from a 1989 cruise includes dissolved inorganic carbon, alkalinity, temperature, salinity, and nutrient measurements. The dataset was collected by researchers from Universite Pierre et Marie Curie using CTD and bottle instruments aboard the MARION DUFRESNE. Observations span from July 30 to September 9, 1989.
Use Cases
- Analyze the relationship between DISSOLVED INORGANIC CARBON (DIC) and TOTAL ALKALINITY (TA) to study ocean carbonate chemistry.
- Model water mass properties using vertical profiles of SALINITY, Potential temperature (theta), and HYDROSTATIC PRESSURE.
- Investigate nutrient distributions by correlating NITRATE, PHOSPHATE, and SILICATE measurements with location and depth.
- Study ocean ventilation and tracer ages using CHLOROFLUOROCARBON-11 (CFC-11), DELTA HELIUM-3, and Tritium data.
- Calibrate ocean models by comparing in-situ DISSOLVED OXYGEN and WATER TEMPERATURE data with simulated outputs.
Strengths
- Includes 14 measured variables for a multi-faceted oceanographic analysis.
- Data collected over a 41-day research cruise provides temporal context.
- Profile and discrete sample data from CTD and bottle instruments offer depth-resolved measurements.
Limitations
- Dataset is from a single cruise in 1989, limiting spatial and temporal representativeness.
- Sample size and row count are unknown, potentially restricting statistical power.
- Data is over 30 years old and may not reflect current ocean conditions.
