CARINA data synthesis project includes chemical and physical oceanographic data collected from the R/V DISCOVERY in the North Atlantic Ocean between June 12 and 24, 1990. The dataset contains discrete sample and profile observations for variables including partial pressure of carbon dioxide, dissolved inorganic carbon, pH, alkalinity, nutrients, temperature, and salinity. Data were collected by researchers from the Commonwealth Scientific and Industrial Research Organization and Plymouth Marine Laboratory using CTD and bottle instruments.
Use Cases
- Modeling ocean carbon uptake based on partial pressure of carbon dioxide and dissolved inorganic carbon measurements.
- Analyzing marine biogeochemical cycles using nitrate, nitrite, phosphate, and silicate data.
- Studying ocean acidification trends based on pH and alkalinity observations.
- Calibrating satellite-derived oceanographic parameters with in-situ temperature and salinity profiles.
Strengths
- Data is part of the CARINA international synthesis project, which aims to produce an internally consistent merged dataset.
- Includes multiple key carbon system variables (pCO2, DIC, pH, alkalinity) and supporting physical/chemical measurements.
- Collected by named principal investigators from recognized research organizations (CSIRO, Plymouth Marine Laboratory).
Limitations
- Last updated 1990-06-24 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.
