A 1994 cruise collected chemical and physical oceanographic data in the Davis Strait, Labrador Sea, and North Atlantic Ocean. Measurements include dissolved inorganic carbon, chlorofluorocarbons, nutrients, salinity, and temperature using CTD and bottle instruments. The data were collected by researchers from the Bedford Institute of Oceanography for the CARINA synthesis project.
Use Cases
- Analyze dissolved inorganic carbon concentration trends with depth using hydrostatic pressure and salinity data.
- Model chlorofluorocarbon (CFC-11, CFC-12, CFC-113) transport pathways using latitude, longitude, and water temperature.
- Correlate nutrient levels (nitrate, phosphate, silicate) with dissolved oxygen measurements to study marine productivity.
- Calculate potential temperature (theta) profiles to understand water mass structure and mixing processes.
Strengths
- Includes 14 measured variables including key carbon cycle and anthropogenic tracers.
- Data collected during a dedicated research cruise over a 19-day period in 1994.
- Part of the CARINA project, an international effort to produce a consistent biogeochemical dataset.
Limitations
- Sample size is limited to one cruise in 1994, providing a snapshot rather than a time series.
- Geographic coverage is restricted to specific regions of the North Atlantic and adjacent seas.
- Data freshness is low, with last measurements from 1994, limiting contemporary climate studies.
