From August 4 to October 13, 1999, this dataset contains discrete sample and profile observations of dissolved inorganic carbon, pH, alkalinity, temperature, salinity, and related variables collected aboard the HAKUREI MARU in the North Pacific Ocean and Philippine Sea. It was collected by Fumiyasu Nishibori and Yutaka W. Watanabe as part of the PACIFICA project, an international synthesis effort for Pacific Ocean interior carbon data.
Use Cases
- Modeling ocean acidification trends based on pH and alkalinity measurements.
- Analyzing carbon sequestration potential based on dissolved inorganic carbon (DIC) and total alkalinity (TA) data.
- Studying biogeochemical cycles based on nitrate, phosphate, silicate, and chlorophyll A concentrations.
- Investigating ocean circulation and mixing using temperature, salinity, and hydrostatic pressure profiles.
- Tracking anthropogenic tracer distribution based on chlorofluorocarbon (CFC) and sulfur hexafluoride (SF6) levels.
Strengths
- Includes a wide range of interrelated chemical, biological, and physical parameters for holistic analysis.
- Data collected over a specific 2-month cruise period, providing a coherent temporal snapshot.
- Part of the PACIFICA international synthesis project, suggesting standardized collection methods.
Limitations
- Last updated 1999-10-13 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.
