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

Discrete profile measurements of dissolved inorganic carbon, alkalinity, pH, temperature, salinity, oxygen, and nutrients collected during the R/V Keifu Maru II cruise ks201701 from 2017-01-10 to 2017-02-23. The dataset covers Repeat Hydrographic Sections P09 and P10 in the North Pacific Ocean and is provided by the National Oceanic and Atmospheric Administration.

Use Cases

• Modeling ocean acidification trends based on dissolved inorganic carbon and pH measurements.
• Analyzing water mass properties and circulation based on temperature and salinity profiles.
• Studying marine biogeochemistry and nutrient cycling based on oxygen and nutrient measurements.

Strengths

• Measurements cover a specific 45-day research cruise in 2017.
• Includes multiple core oceanographic variables (DIC, alkalinity, pH, temperature, salinity, oxygen, nutrients).
• Data is associated with defined repeat hydrographic sections (P09, P10).

Limitations

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