PACIFICA_49SU19990428 includes discrete sample and profile data collected from the SHUMPU MARU in the Philippine Sea from 1999-04-28 to 1999-05-06. The data set contains measurements for alkalinity, dissolved inorganic carbon, chlorofluorocarbons, nutrients, chlorophyll, and related parameters. These data were collected by Tatsuo Nakamura and Masao Ishii as part of the PACIFICA international collaborative project for synthesizing Pacific Ocean interior carbon data.
Use Cases
- Modeling ocean acidification based on pH and dissolved inorganic carbon measurements.
- Analyzing nutrient cycling patterns based on nitrate, phosphate, and silicate concentrations.
- Studying chlorofluorocarbon distribution and ocean ventilation based on CFC-11 and CFC-12 data.
- Investigating phytoplankton biomass based on chlorophyll a and phaeopigment measurements.
- Calculating carbon export potential based on dissolved organic carbon and total phosphorus.
Strengths
- Data covers 22 distinct chemical, biological, and physical parameters, including key carbon cycle variables.
- Measurements were collected using specific instruments like CTD and Coulometer for DIC, indicating a standardized methodology.
- Data is part of the PACIFICA international synthesis project, suggesting a collaborative and curated effort.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 1999-05-06; freshness should be verified for contemporary applications.
- Row count is unknown, which may limit suitability assessment for large-scale modeling.
