PACIFICA_49EW19991007 collected discrete chemical and physical measurements from the BOSEI MARU NO. 2 vessel in the North Pacific Ocean between October 7 and 26, 1999. The data include dissolved inorganic carbon, alkalinity, pH, nutrients, salinity, and temperature. Nobuo Tsurushima of the Advanced Industrial Science and Technology collected these data as part of the PACIFICA project, an international synthesis effort for Pacific Ocean interior carbon.
Use Cases
- Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing nutrient cycles and their relationship to carbon chemistry based on nitrate, phosphate, and silicate data.
- Studying the physical-chemical structure of the ocean water column based on CTD-derived temperature, salinity, and pressure profiles.
- Calibrating or validating regional carbon models using in-situ measurements from a specific cruise.
Strengths
- Data covers a specific 19-day research cruise in October 1999, providing a temporally focused snapshot.
- Includes multiple key carbon system parameters (DIC, alkalinity, pH) alongside supporting nutrients and physical variables.
- Data were collected as part of the international PACIFICA project, suggesting a standardized synthesis effort.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 1999-10-26 00:00:00; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
