March to April 2016 discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH, temperature, salinity, oxygen, nutrients, and chlorofluorocarbons collected during the R/V Roger Revelle cruise along GO-SHIP Section I09N in the Indian Ocean. Data were gathered using CTD and Niskin bottle instruments and are provided by the National Oceanic and Atmospheric Administration.
Use Cases
- Modeling ocean acidification based on pH and dissolved inorganic carbon measurements
- Analyzing nutrient cycling in the Indian Ocean based on nitrate and nitrite data
- Studying ocean ventilation and circulation based on chlorofluorocarbon (CFC-11, CFC-12) concentrations
- Investigating biogeochemical relationships based on co-located temperature, salinity, oxygen, and alkalinity profiles
Strengths
- Data includes multiple co-located chemical and physical variables (DIC, alkalinity, pH, nutrients, CFCs, temperature, salinity, oxygen)
- Measurements were collected during a dedicated repeat hydrography cruise (GO-SHIP) using standardized instruments (CTD, Niskin bottle)
- Specific temporal coverage from March 21 to April 28, 2016
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 bias inherent to the single cruise track in the Indian Ocean
