Discrete chemical and physical oceanographic data collected from the NOAA Ship MALCOLM BALDRIGE in the Indian Ocean and Laccadive Sea from September to October 1995. The data include measurements of carbon dioxide partial pressure, dissolved inorganic carbon, alkalinity, pH, temperature, salinity, nutrients, and chlorofluorocarbons. These data were collected by researchers from the Rosenstiel School of Marine and Atmospheric Science and NOAA's Atlantic Oceanographic and Meteorological Laboratory as part of the World Ocean Circulation Experiment (WOCE).
Use Cases
- Calibrating or validating ocean carbon cycle models based on direct measurements of dissolved inorganic carbon and alkalinity.
- Analyzing historical ocean acidification trends based on pH and carbon dioxide partial pressure measurements.
- Studying ocean ventilation and water mass age using chlorofluorocarbon (CFC-11, CFC-12) tracer data.
- Investigating nutrient dynamics and primary productivity in the Indian Ocean based on nitrate, nitrite, phosphate, and silicate measurements.
Strengths
- Data includes multiple co-located chemical and physical variables relevant for carbon cycle studies, such as DIC, alkalinity, pH, and CFCs.
- Collection is part of the well-regarded World Ocean Circulation Experiment (WOCE), which aimed for high-quality, globally coordinated ocean observations.
- Specific time range (1995-09-22 to 1995-10-25) and geographic area (Indian Ocean, Laccadive Sea) are clearly defined.
Limitations
- Last updated 1995-10-25 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
