November 15 to December 19, 1994, this dataset contains chemical, physical, and profile measurements from the Atlantic Ocean and adjacent seas. It includes data on dissolved inorganic carbon, chlorofluorocarbons, nutrients, and water properties collected during the CARINA/06MT303 and WOCE_A01EW cruises. The data were gathered by researchers from Dalhousie University and Universitat Kiel using CTD and bottle instruments.
Use Cases
- Analyzing dissolved inorganic carbon concentration trends with salinity and water temperature to study ocean acidification.
- Correlating chlorofluorocarbon (CFC-11, CFC-12) levels with tritium and helium-3 to trace ocean ventilation and anthropogenic impact.
- Modeling nutrient cycles by examining nitrate+nitrite, phosphate, and silicate concentrations across ocean profiles.
- Studying water column structure using potential temperature (theta) and hydrostatic pressure data from CTD profiles.
- Investigating dissolved oxygen levels in relation to other chemical variables for biogeochemical process studies.
Strengths
- Data covers a specific, well-documented cruise period from 1994-11-15 to 1994-12-19.
- Includes 15 distinct chemical and physical variables, such as CFCs, carbon isotopes, and nutrients.
- Part of the international CARINA synthesis project, aimed at producing an internally consistent data set.
Limitations
- Data is from a single, short cruise in 1994, providing a snapshot rather than a long-term time series.
- Geographic coverage is limited to specific transects in the Atlantic and Arctic, not a global survey.
- The dataset's age (1994) means it represents historical conditions and may not reflect current ocean states.
