Discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH on total

National Oceanic and Atmospheric Administration data from the R/V Mirai cruise provides discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH, chlorofluorocarbons, and other hydrographic variables. The data was collected in the North Pacific Ocean, East China Sea, and Japan Sea during the GO-SHIP/CLIVAR Repeat Hydrography Section P03 Leg 3 from January 20 to 30, 2006.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and pH measurements.
• Analyzing ocean circulation and water mass age based on chlorofluorocarbon (CFC) tracers.
• Studying marine biogeochemical cycles based on nutrient and oxygen profile data.
• Calibrating and validating ocean carbon system models based on co-located DIC, alkalinity, and hydrographic variables.

Strengths

• Includes multiple co-located carbon system variables (DIC, alkalinity, pH) for robust analysis.
• Data collected on a standardized GO-SHIP/CLIVAR repeat hydrography section, ensuring methodological consistency.
• Covers a specific transect in the North Pacific, East China Sea, and Japan Sea during a defined 10-day period in 2006.

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 ML tasks.
