From May 26 to June 18, 2006, this dataset contains chemical and physical measurements from the North Pacific Ocean collected during cruise MR06-03. It includes dissolved inorganic carbon, alkalinity, pH, nutrients, and temperature data from discrete samples and CTD profiles. The data were collected by researchers from the Japan Agency for Marine-Earth Science and Technology as part of the PACIFICA project.
Use Cases
- Modeling ocean carbon uptake based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing nutrient distributions and ocean productivity based on nitrate, phosphate, and silicate data.
- Studying ocean acidification trends based on pH and alkalinity profiles.
- Calibrating ocean carbon models based on hydrostatic pressure, salinity, and temperature data.
Strengths
- Data includes 12 measured variables, including key carbon system parameters like DIC and alkalinity.
- Samples were collected using specific instruments like CTD and Coulometer, suggesting methodological consistency.
- Data is part of the international PACIFICA project, indicating a collaborative synthesis effort.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified; the metadata was last updated in 2026.
