From February 20 to March 30, 2003, chemical and physical data were collected from discrete samples and profiles aboard the MIRAI research vessel in the North Pacific Ocean. The data include dissolved inorganic carbon, pH, alkalinity, temperature, salinity, nutrients, and dissolved oxygen, measured using CTD, Coulometer, and bottle instruments. These observations were collected by researchers from JAMSTEC and the Meteorological Research Institute as part of the PACIFICA international collaborative project.
Use Cases
- Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements.
- Analyzing nutrient cycling in the North Pacific based on nitrate, nitrite, phosphate, and silicate data.
- Studying the relationship between physical and chemical ocean properties based on concurrent temperature, salinity, and hydrostatic pressure profiles.
- Calibrating or validating ocean carbon models based on discrete sample alkalinity and DIC data.
Strengths
- Data covers a specific cruise period from February 20 to March 30, 2003.
- Includes multiple key ocean carbon and nutrient parameters such as DIC, pH, alkalinity, and ammonium.
- Data were collected as part of an international collaborative project (PACIFICA) supported by PICES.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic and temporal bias inherent to a single cruise in the North Pacific Ocean.
