Dissolved Inorganic Carbon and CFC Measurements from Hudson Cruise in Davis Strait

June 1993 data includes chemical, physical, and profile measurements collected from the Hudson vessel in the Davis Strait and Labrador Sea. The dataset contains 13 variables, including dissolved inorganic carbon, chlorofluorocarbons, nutrients, salinity, and temperature. It was gathered by researchers from the Bedford Institute of Oceanography during the CARINA/18HU19930617 cruise.

Use Cases

• Analyze correlations between DISSOLVED INORGANIC CARBON and WATER TEMPERATURE or SALINITY to model carbon system dynamics.
• Study the distribution of CHLOROFLUOROCARBON-11 (CFC-11) and CHLOROFLUOROCARBON-12 (CFC-12) as tracers of ocean ventilation and anthropogenic impact.
• Model NITRATE, PHOSPHATE, and SILICATE concentrations against HYDROSTATIC PRESSURE (depth) to understand nutrient profiles.
• Calculate Potential temperature (theta) from WATER TEMPERATURE and SALINITY for thermodynamic analysis of water masses.
• Use DISSOLVED OXYGEN data alongside carbon tetrachloride (CCL4) measurements for investigations into ocean biogeochemical processes.

Strengths

• Contains 13 distinct chemical and physical variables per observation.
• Data collected during a dedicated scientific cruise (CARINA/18HU19930617) using CTD and bottle instruments.
• Part of the CARINA synthesis project, aimed at producing an internally consistent data set for biogeochemical investigations.

Limitations

• Temporal coverage is limited to a single cruise over 13 days in June 1993.
• Geographic coverage is restricted to two specific regions: the Davis Strait and Labrador Sea.
• Key metadata such as row count, sample size, and data completeness are unknown.
