February to March 2007 discrete profile measurements of dissolved inorganic carbon, total alkalinity, temperature, salinity, dissolved oxygen, nutrients, chlorofluorocarbons, dissolved organic carbon, tritium, and helium from the R/V Roger Revelle cruise in the Indian Ocean. The data were collected by researchers from NOAA PMEL, Scripps Institution of Oceanography, and RSMAS as part of the CLIVAR Global Ocean Carbon and Repeat Hydrography Program. This program aims to quantify changes in the storage and transport of heat, fresh water, and carbon dioxide.
Use Cases
- Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and total alkalinity measurements.
- Analyzing water mass age and circulation using chlorofluorocarbon (CFC-11, CFC-12) and tritium/helium tracer data.
- Studying nutrient dynamics and biological productivity in the Indian Ocean based on nitrate and nitrite profiles.
- Investigating ocean acidification trends by examining carbonate system parameters like DIC and alkalinity.
Strengths
- Data collection involved multiple authoritative institutions including NOAA PMEL, Scripps Institution of Oceanography, and RSMAS.
- The dataset includes a multi-parameter suite of measurements relevant to ocean carbon and climate studies.
- Measurements were taken during a dedicated research cruise (CLIVAR_I08S_2007) from February 4 to March 17, 2007.
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 analyses.
- The dataset's specific file format is HTML, which may not be a standard data format for scientific analysis.
