Dissolved inorganic carbon (DIC), total alkalinity, pH on total scale, temperature, salini

North Pacific Ocean data collected from discrete samples and profiles during the R/V Keifu Maru II cruise ks201804 from 2018-04-06 to 2018-05 12. The dataset includes dissolved inorganic carbon, total alkalinity, pH, temperature, salinity, oxygen, and nutrient measurements. It was contributed by the National Oceanic and Atmospheric Administration, Department of Commerce.

Use Cases

• Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements.
• Analyzing water column biogeochemistry based on profile observations of nutrients and oxygen.
• Studying carbon system parameters based on total alkalinity and DIC data.
• Investigating physical oceanographic conditions based on temperature and salinity profiles.

Strengths

• Contains multiple key ocean carbon system variables (DIC, alkalinity, pH) for a single research cruise.
• Data collection occurred over a defined period from 2018-04-06 to 2018-05-12.
• Includes both discrete samples and profile observations, likely providing depth-resolved data.

Limitations

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