NODC Accession 0112308 includes biological, chemical, and physical profile data collected from the SHUMPU MARU in the Philippine Sea from 1999-07-09 to 1999-07-17. The data were collected by Shunta Naito and Masao Ishii as part of the PACIFICA project, an international synthesis effort for Pacific Ocean interior carbon data. Measurements include dissolved inorganic carbon, pH, alkalinity, nutrients, chlorophyll, and chlorofluorocarbons.
Use Cases
- Modeling ocean acidification dynamics based on dissolved inorganic carbon, pH, and alkalinity measurements.
- Studying nutrient cycling and primary productivity based on nitrate, phosphate, silicate, and chlorophyll a data.
- Analyzing anthropogenic tracer distribution based on chlorofluorocarbon-11 and -12 measurements.
- Investigating water mass properties and ocean circulation based on temperature, salinity, and potential temperature profiles.
Strengths
- Includes over 20 measured variables covering carbon chemistry, nutrients, and physical oceanography.
- Data were collected as part of the international PACIFICA synthesis project, suggesting standardized protocols.
- Provides discrete sample and profile observations from a specific cruise, offering vertical context.
Limitations
- Last updated 1999-07-17 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
