North Pacific Ocean Carbon and Nutrient Profiles from R/V Keifu Maru II Cruise, April 2012

Discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH, temperature, salinity, oxygen, and nutrients collected during the R/V Keifu Maru II cruise ks201203 in the North Pacific Ocean from 2012-04-10 to 2012-04-24. The dataset is provided by the National Oceanic and Atmospheric Administration and was last updated in March 2026.

Use Cases

• Modeling ocean acidification processes based on dissolved inorganic carbon and pH measurements
• Analyzing marine biogeochemical cycles based on nutrient and oxygen profiles
• Calibrating oceanographic models based on discrete temperature and salinity measurements
• Assessing carbon sequestration potential based on total alkalinity data

Strengths

• Data covers a specific 15-day cruise in April 2012, providing a temporal snapshot.
• Includes multiple key oceanographic variables (DIC, alkalinity, pH, nutrients) for a holistic view.
• Sourced from a NOAA cruise, suggesting institutional credibility.

Limitations

• Row count and data volume are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic and temporal bias inherent to a single cruise.
