South Pacific Ocean Carbon Chemistry Profiles from 1997

From 1997-10-20 to 1997-11-24, the ROGER REVELLE research vessel collected discrete and profile data in the South Pacific Ocean. The dataset includes measurements of dissolved inorganic carbon, pH, alkalinity, nutrients, oxygen, temperature, and salinity using CTD and bottle instruments. Timothy J. Cowles of Oregon State University and Frank J. Millero of the Rosenstiel School collected this data as part of the CLIVAR Global Ocean Carbon and Repeat Hydrography Program.

Use Cases

• Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and alkalinity measurements.
• Analyzing nutrient dynamics and biogeochemical cycles based on nitrate, phosphate, and silicate data.
• Studying water mass properties and ocean circulation based on temperature, salinity, and hydrostatic pressure profiles.
• Investigating particulate organic matter fluxes based on particulate organic carbon and nitrogen data.

Strengths

• Data covers a specific 35-day research cruise in the South Pacific Ocean from October to November 1997.
• Includes 15 distinct chemical and physical variables relevant to carbon cycle and ocean acidification studies.
• Collected as part of the systematic CLIVAR Global Ocean Carbon and Repeat Hydrography Program.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic and temporal bias inherent to a single, localized cruise.
