North Pacific Ocean and Sea of Japan Seawater Chemistry Profiles from 2010

Discrete profile measurements of dissolved inorganic carbon, alkalinity, pH, temperature, salinity, oxygen, and nutrients collected during the R/V Keifu Maru II cruise ks201007. The data was gathered by the National Oceanic and Atmospheric Administration in the North Pacific Ocean and Sea of Japan from 2010-10-02 to 2010-11-04.

Use Cases

• Modeling ocean acidification trends based on dissolved inorganic carbon and pH measurements.
• Studying carbon cycling in marine ecosystems based on total alkalinity and nutrient data.
• Analyzing water mass properties and oceanographic conditions based on temperature, salinity, and oxygen profiles.

Strengths

• Data collection spans a specific cruise from 2010-10-02 to 2010 11-04, providing a temporal snapshot.
• Includes multiple co-located seawater chemistry variables (DIC, alkalinity, pH, nutrients, oxygen, temperature, salinity).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
