North Pacific and East China Sea Ocean Carbon and Acidification Measurements from 2010

A 2010 cruise (RF10-02) collected discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH, temperature, salinity, oxygen, and nutrients in the North Pacific Ocean and East China Sea. The data was gathered by the National Oceanic and Atmospheric Administration from April 14 to May 7, 2010.

Use Cases

• Modeling ocean acidification trends based on dissolved inorganic carbon and pH measurements
• Studying marine biogeochemical cycles based on nutrient and oxygen profile data
• Analyzing water mass properties based on concurrent temperature and salinity profiles
• Calibrating and validating ocean carbon system models based on discrete alkalinity and DIC observations

Strengths

• Includes multiple key ocean carbon system variables (DIC, alkalinity, pH) measured concurrently
• Data collected during a dedicated research cruise (RF10-02) over a defined period in 2010
• Profile measurements provide vertical structure information for the water column

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Description metadata is limited; actual data quality requires manual inspection after download
