CLIVAR P16S 2005: South Pacific Ocean Hydrographic and Carbon Chemistry Profiles

January 9 to February 19, 2005, discrete profile measurements of dissolved inorganic carbon, alkalinity, chlorofluorocarbons, and other hydrographic variables collected during the R/V Roger Revelle cruise CLIVAR_P16S_2005 in the South Pacific Ocean. The data were gathered as part of the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program to quantify changes in ocean heat, freshwater, and carbon dioxide storage. The dataset is provided by the National Oceanic and Atmospheric Administration.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and total alkalinity measurements
• Studying ocean ventilation and circulation timescales based on chlorofluorocarbon (CFC) and tracer data
• Analyzing water mass properties and biogeochemical processes based on concurrent temperature, salinity, oxygen, and nutrient profiles

Strengths

• Includes multiple core carbon system variables (DIC, alkalinity, DOC) measured concurrently.
• Data collection is part of a systematic global re-occupation program (CLIVAR) for change detection.
• Covers a specific 41-day cruise in the South Pacific Ocean with a known time range.

Limitations

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