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

NOAA collected discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH, temperature, salinity, oxygen, and nutrients during the R/V Keifu Maru II cruise ks201703 in the North Pacific Ocean. The data covers a specific cruise from 2017-04-08 to 2017-04-26. It is part of the Ocean Carbon and Acidification Data System (OCADS).

Use Cases

• Modeling ocean acidification trends based on dissolved inorganic carbon and pH measurements.
• Studying marine biogeochemical cycles based on nutrient and oxygen profile data.
• Calibrating ocean carbon sensors based on discrete, co-located measurements of temperature, salinity, and alkalinity.

Strengths

• Data is from a specific, well-documented research cruise (ks201703) with a known time range (2017-04-08 to 2017-04-26).
• Includes a suite of co-located variables critical for ocean carbon system calculations (DIC, alkalinity, pH, temperature, salinity).
• Sourced from the authoritative NOAA Ocean Carbon and Acidification Data System (OCADS).

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.
