Chemical and physical oceanographic data collected from the DISCOVERY research vessel in the Indian Ocean during December 2004 and January 2005. The dataset includes measurements of dissolved inorganic carbon, alkalinity, dissolved oxygen, nutrients, salinity, and temperature from discrete bottle samples and CTD profiles. Data were collected by researchers from the National Oceanography Centre, Southampton and the University of East Anglia as part of the CARINA (CARbon dioxide IN the Atlantic Ocean) international synthesis project.
Use Cases
- Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and alkalinity measurements
- Analyzing nutrient distributions and ocean productivity based on nitrate, phosphate, and silicate data
- Studying water column structure and ocean circulation based on CTD-derived salinity, temperature, and pressure profiles
- Calibrating and validating biogeochemical ocean models based on the internally consistent CARINA synthesis data
Strengths
- Data collected during a specific research cruise (CARINA/74DI20041213) providing a coherent snapshot
- Includes multiple key biogeochemical variables (alkalinity, DIC, oxygen, nutrients) for integrated analysis
- Part of the CARINA international synthesis project, which aimed to produce an internally consistent dataset
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Geographic coverage is limited to a single cruise track in the Indian Ocean over a specific time period
