CLIVAR P14 2007: Ocean Carbon and Hydrography Measurements from the Pacific

From October to December 2007, the MIRAI research vessel collected surface, profile, and discrete sample data in the Bering Sea, North Pacific, and South Pacific Oceans. The dataset includes measurements of dissolved inorganic carbon, alkalinity, pH, CFCs, nutrients, and other oceanographic parameters. Data were collected by researchers from JAMSTEC and the Meteorological Research Institute as part of the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program.

Use Cases

• Modeling ocean carbon storage and transport based on dissolved inorganic carbon and alkalinity measurements.
• Studying ocean acidification trends based on pH and carbonate system parameters.
• Tracing water mass age and circulation using chlorofluorocarbon (CFC-11, CFC-12, CFC-113) concentrations.
• Analyzing nutrient cycles and primary productivity based on nitrate, phosphate, and silicate data.

Strengths

• Data collection spanned a specific cruise from 2007-10-08 to 2007-12-26, providing a focused temporal snapshot.
• Includes over 15 measured variables, such as DIC, alkalinity, CFCs, nutrients, and stable isotopes.
• Data were collected using multiple instrument types, including CTD, alkalinity titrator, and CO2 analyzers, suggesting methodological rigor.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the specific CLIVAR P14 2007 cruise track.
