North Pacific Ocean Carbon and Water Chemistry Profiles from Cruise KS09-10, 2009

Discrete profile measurements of dissolved inorganic carbon, pH, temperature, salinity, oxygen, and nutrients collected during the R/V Keifu Maru II cruise KS09-10 in the North Pacific Ocean from 2009-10-20 to 2009 11-26. The dataset was contributed by the National Oceanic and Atmospheric Administration and last updated in March 2026.

Use Cases

• Modeling ocean acidification trends based on dissolved inorganic carbon and pH measurements.
• Analyzing water column biogeochemistry based on nutrient and oxygen profiles.
• Calibrating satellite or model data with in-situ temperature and salinity observations.

Strengths

• Includes multiple key oceanographic variables (DIC, pH, temperature, salinity, oxygen, nutrients) for a holistic view.
• Data is associated with a specific research cruise (KS09-10) and time period (Oct-Nov 2009), providing temporal context.

Limitations

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