North Pacific Ocean Carbon and Water Chemistry Profiles from 2009

Discrete profile measurements of dissolved inorganic carbon, alkalinity, pH, temperature, salinity, oxygen, and nutrients collected during the R/V Ryofu Maru III cruise RF09 -09. The data was gathered in the North Pacific Ocean from 2009-09-16 to 2009-11 11 by the National Oceanic and Atmospheric Administration.

Use Cases

• Modeling ocean acidification dynamics based on dissolved inorganic carbon and pH measurements
• Studying marine carbon cycling based on total alkalinity and nutrient data
• Analyzing water mass properties based on concurrent temperature and salinity profiles
• Investigating biological productivity based on oxygen and nutrient concentrations

Strengths

• Data covers a specific research cruise from 2009-09-16 to 2009-11-11, providing a temporal snapshot.
• Includes multiple co-located chemical and physical parameters for water column analysis.

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 and temporal bias inherent to a single cruise.
