North Pacific Ocean chemical and physical data collected from discrete samples and profiles aboard the Soyo Maru from May 9 to May 29, 1997. The data include alkalinity, dissolved inorganic carbon, dissolved oxygen, nitrate, phosphate, silicate, salinity, and water temperature. Tsuneo Ono and Katsuyuki Sasaki of the National Research Institute of Fisheries Science collected these measurements as part of the PACIFICA international synthesis project.
Use Cases
- Analyzing ocean acidification trends based on alkalinity and dissolved inorganic carbon measurements.
- Studying nutrient cycling and marine productivity based on nitrate, phosphate, and silicate data.
- Modeling carbon sequestration in the ocean interior based on dissolved inorganic carbon and related parameters.
- Investigating physical-chemical relationships in seawater based on concurrent temperature, salinity, and hydrostatic pressure measurements.
Strengths
- Data covers a specific 20-day cruise in the North Pacific Ocean in May 1997.
- Includes multiple key oceanographic parameters: alkalinity, dissolved inorganic carbon, dissolved oxygen, and nutrients.
- Data were collected as part of the international PACIFICA project, suggesting standardized protocols.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 1997-05-29; freshness should be verified.
