Discrete chemical and physical measurements collected from the Soyo Maru in the North Pacific Ocean from August 20 to 27, 1997. The data includes alkalinity, dissolved inorganic carbon, dissolved oxygen, nitrate, phosphate, silicate, salinity, and water temperature. These observations were collected by researchers from the National Research Institute of Fisheries Science as part of the PACIFICA international collaborative project.
Use Cases
- Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and alkalinity measurements
- Analyzing nutrient distributions and biogeochemical cycles based on nitrate, phosphate, and silicate data
- Studying physical oceanographic properties based on concurrent salinity and water temperature profiles
- Investigating dissolved oxygen levels and their relationship to other chemical parameters
Strengths
- Data covers a specific 8-day cruise in the North Pacific Ocean from 1997-08-20 to 1997-08-27
- Includes multiple key oceanographic variables: alkalinity, DIC, oxygen, nutrients, salinity, and temperature
- Data originates from a recognized international collaborative project (PACIFICA) supported by PICES
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Last updated 1997-08-27 00:00:00; freshness should be verified
- Row count is unknown, which may limit suitability assessment
