PACIFICA (PACIFic ocean Interior CArbon) project data includes ALKALINITY, DISSOLVED INORGANIC CARBON, pH, and other chemical and physical variables. The data were collected from the Hokusei Maru in the North Pacific Ocean from June 22 to July 6, 1999 using CTD, Coulometer, and bottle instruments. Shuichi Watanabe of JAMSTEC; Mutsu Institute for Oceanography (MIO) collected these data as part of cruise HO99-2.
Use Cases
- Modeling ocean carbon sequestration based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing nutrient cycling patterns based on nitrate, nitrite, phosphate, and silicate concentrations.
- Studying ocean acidification trends based on pH and carbonate system parameters.
- Correlating physical oceanographic conditions with chemical profiles based on temperature, salinity, and hydrostatic pressure.
Strengths
- Data covers a specific 15-day cruise in the North Pacific Ocean from 1999-06-22 to 1999-07-06.
- Includes 12 distinct chemical and physical variables, such as ALKALINITY, DISSOLVED INORGANIC CARBON, pH, and DISSOLVED OXYGEN.
- Part of the international PACIFICA project for data synthesis of ocean interior carbon.
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 temporal bias inherent to a single cruise in 1999.
