Discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH, temperature, salinity, oxygen, and nutrients collected during the R/V Keifu Maru II cruise KS12-02 in the North Pacific Ocean. The cruise occurred from 2012-02-04 to 2012-03-24, and the dataset is managed by the National Oceanic and Atmospheric Administration.
Use Cases
- Modeling ocean acidification trends based on dissolved inorganic carbon and pH measurements
- Analyzing marine biogeochemical cycles based on nutrient and oxygen profiles
- Studying carbonate system dynamics based on total alkalinity and dissolved inorganic carbon
- Calibrating oceanographic models based on concurrent temperature and salinity measurements
Strengths
- Data covers a specific research cruise (KS12-02) with a known EXPOCODE (49UF20120204)
- Includes multiple concurrent chemical and physical measurements (DIC, alkalinity, pH, temperature, salinity, oxygen, nutrients)
- Temporal coverage is precisely defined from 2012-02-04 to 2012-03-24
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 bias inherent to a single cruise track in the North Pacific Ocean
