CARINA project data from the Hudson cruise in May-June 1992 includes measurements of dissolved inorganic carbon, chlorofluorocarbons, nitrate, phosphate, silicate, dissolved oxygen, salinity, and water temperature. The data were collected by researchers from the Bedford Institute of Oceanography using CTD and bottle instruments in the Labrador Sea and North Atlantic Ocean. This dataset is part of an international synthesis effort for biogeochemical investigations.
Use Cases
- Analyze correlations between dissolved inorganic carbon and salinity or water temperature to study carbon system dynamics.
- Model the distribution of chlorofluorocarbons (CFC-11, CFC-12, CFC-113, CCL4) as tracers for ocean circulation and ventilation.
- Investigate nutrient ratios (nitrate, phosphate, silicate) relative to dissolved oxygen levels to assess biological productivity.
- Use hydrostatic pressure and potential temperature (theta) data to construct vertical profiles of ocean properties.
Strengths
- Includes 13 measured variables covering key ocean carbon and nutrient cycles.
- Data is part of the CARINA merged synthesis project, ensuring internal consistency for biogeochemical studies.
- Provides discrete sample and profile observations from a specific research cruise, offering a coherent snapshot.
Limitations
- Temporal coverage is limited to a single cruise over 19 days in 1992, offering no longitudinal perspective.
- Geographic coverage is restricted to stations in the Labrador Sea and North Atlantic Ocean during this cruise.
- Sample size (row count) and data resolution (vertical/horizontal) are unknown, which may limit statistical power.
