Indian Ocean data collected from the Hakuho Maru vessel between December 1994 and January 1995. The dataset contains discrete sample and profile observations for dissolved inorganic carbon, alkalinity, pH, nutrients, chlorophyll A, and physical variables. Data were collected by researchers from the Meteorological Research Institute and others as part of the CARINA synthesis project.
Use Cases
- Model ocean acidification by analyzing pH, dissolved inorganic carbon, and alkalinity measurements across the cruise track.
- Study nutrient dynamics and primary production by correlating nitrate, phosphate, silicate, and chlorophyll A concentrations.
- Analyze water column structure using CTD profile data for potential temperature, salinity, hydrostatic pressure, and dissolved oxygen.
- Validate regional carbon cycle models using internally consistent CARINA data for dissolved inorganic carbon and related variables.
Strengths
- Includes 13 key biogeochemical and physical variables for carbon system studies.
- Data is part of the CARINA merged synthesis project, ensuring internal consistency for analysis.
Limitations
- Limited temporal coverage to a single 47-day cruise in 1994-1995.
- Geographic scope is restricted to the specific track of the Hakuho Maru in the Indian Ocean.
- Sample size and row count are unknown, limiting assessment of statistical power.
