CARINA data set includes chemical and physical measurements from the DISCOVERY research vessel in the North Atlantic Ocean. The data contain dissolved inorganic carbon, dissolved oxygen, nutrients, salinity, and temperature collected during a cruise from June 12 to July 9, 1989. Andrew Watson of Plymouth Marine Laboratory collected the data using CTD and bottle instruments.
Use Cases
- Analyze dissolved inorganic carbon concentration trends with salinity and water temperature across the North Atlantic.
- Model nitrate and phosphate relationships with hydrostatic pressure and potential temperature for nutrient cycling studies.
- Assess dissolved oxygen levels correlated with silicate and nitrite measurements for marine biogeochemical investigations.
- Study the spatial distribution of carbon system variables like dissolved inorganic carbon and salinity from discrete sample profiles.
Strengths
- Data is part of the CARINA international synthesis project, producing an internally consistent merged data set.
- Includes multiple key biogeochemical variables: dissolved inorganic carbon, dissolved oxygen, nitrate, phosphate, silicate, salinity, and temperature.
- Data collected using standard oceanographic instruments (CTD and bottle) during a defined cruise period.
Limitations
- Data is from a single cruise in 1989, providing a limited temporal snapshot rather than a long-term series.
- Geographic coverage is restricted to the North Atlantic Ocean during this specific cruise.
- Sample size and row count are unknown, potentially limiting statistical analysis.
