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

Discrete profile measurements of dissolved inorganic carbon, alkalinity, pH, and other oceanographic variables were collected during the R/V Keifu Maru II cruise ks201110 in the North Pacific Ocean. The dataset, originating from the National Oceanic and Atmospheric Administration, covers a specific expedition from December 5 to December 21, 2011. It is part of the Ocean Carbon and Acidification Data System (OCADS).

Use Cases

• Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements.
• Analyzing marine biogeochemistry based on nutrient and oxygen profile data.
• Calibrating satellite-derived ocean data based on in-situ salinity and temperature profiles.
• Studying carbon sequestration potential based on total alkalinity and DIC measurements.

Strengths

• Data is associated with a specific, documented research cruise (EXPOCODE 49UF20111205).
• Includes multiple co-located variables (DIC, alkalinity, pH, nutrients) for multivariate analysis.
• Originates from the authoritative NOAA organization and the Ocean Carbon and Acidification Data System.

Limitations

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