Chemical, physical, and profile data were collected from the MIRAI research vessel in the North Pacific Ocean from 2004-03-27 to 2004-04-17 during cruise MR04-02. The data include dissolved inorganic carbon, alkalinity, pH, nutrients, and hydrographic parameters measured using CTD, Coulometer, and bottle samples. Makio Honda of the Japan Agency for Marine-Earth Science and Technology collected these observations as part of the PACIFICA international synthesis project.
Use Cases
- Modeling ocean carbon sequestration based on dissolved inorganic carbon and alkalinity measurements.
- Studying nutrient dynamics in the North Pacific based on nitrate, phosphate, and silicate data.
- Calibrating ocean acidification models based on concurrent pH, DIC, and alkalinity profiles.
- Analyzing water mass properties based on correlated temperature, salinity, and dissolved oxygen profiles.
Strengths
- Data includes multiple co-located chemical and physical parameters (e.g., DIC, pH, nutrients, temperature, salinity) for multivariate analysis.
- Collected during a dedicated research cruise (MR04-02) over a focused three-week period in 2004.
- Part of the international PACIFICA project for data synthesis, suggesting standardized collection protocols.
Limitations
- Row count and dataset scale are unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Data may reflect temporal and geographic bias inherent to a single cruise in the North Pacific.
