Arctic Ocean and Beaufort Sea data collected during a 1997 research cruise aboard the LOUIS S. ST. LAURENT. The dataset contains discrete measurements of dissolved inorganic carbon, alkalinity, chlorofluorocarbons, nutrients, dissolved oxygen, salinity, and temperature. It was collected by researchers from the Bedford Institute of Oceanography and Scripps Institution of Oceanography as part of the CARINA synthesis project.
Use Cases
- Calculate ocean acidification parameters like pCO2 and pH from DISSOLVED INORGANIC CARBON and ALKALINITY measurements paired with SALINITY and WATER TEMPERATURE.
- Trace water mass age and circulation patterns using CHLOROFLUOROCARBON-11 (CFC-11) and CHLOROFLUOROCARBON-12 (CFC-12) concentrations versus HYDROSTATIC PRESSURE (depth).
- Analyze nutrient stoichiometry and biological consumption by correlating NITRATE, PHOSPHATE, and SILICATE levels with DISSOLVED OXYGEN across profiles.
- Study Arctic water column structure by examining Potential temperature (theta) and SALINITY relationships from CTD profiles.
Strengths
- Data is part of the curated, internally consistent CARINA international synthesis project for biogeochemical investigations.
- Includes multiple co-located carbon system variables (ALKALINITY, DISSOLVED INORGANIC CARBON) and transient tracers (CFCs) for robust analysis.
Limitations
- Temporal coverage is limited to a single cruise from September to October 1997, lacking seasonal or long-term time-series context.
- Geographic scope is restricted to specific stations in the Arctic Ocean and Beaufort Sea during that cruise.
