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

The North Pacific Ocean is the region for this dataset of discrete profile measurements collected during the R/V Ryofu Maru III cruise rf201804 from 2018-05-01 to 2018-06 05. It includes dissolved inorganic carbon, total alkalinity, pH, temperature, salinity, oxygen, and nutrients. The data was contributed by the National Oceanic and Atmospheric Administration.

Use Cases

• Modeling ocean acidification dynamics based on dissolved inorganic carbon and pH measurements.
• Studying carbon sequestration potential based on total alkalinity and DIC profiles.
• Analyzing ocean biogeochemistry based on concurrent nutrient and oxygen measurements.
• Calibrating and validating satellite or model-derived ocean carbon data based on in-situ discrete samples.

Strengths

• Includes multiple key ocean carbon system variables (DIC, alkalinity, pH) for a holistic view.
• Data is associated with a specific research cruise (rf201804) providing a controlled collection context.
• Covers a defined temporal range from 2018-05-01 to 2018 06-05.

Limitations

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