April 19 to May 16, 1995 data from the Hudson research vessel in the Gulf of St. Lawrence and North Atlantic Ocean. It contains discrete sample and profile measurements of dissolved inorganic carbon, chlorofluorocarbons, dissolved oxygen, nutrients, temperature, and salinity. The data were collected by researchers from the Bedford Institute of Oceanography and CSIRO as part of the CARINA synthesis project.
Use Cases
- Analyze dissolved inorganic carbon (DIC) concentration trends relative to salinity and water temperature across depth profiles.
- Model chlorofluorocarbon (CFC-11, CFC-12, CFC-113) distributions as tracers for ocean ventilation and mixing processes.
- Correlate nutrient levels (nitrate, phosphate, silicate) with dissolved oxygen measurements to assess biological activity.
- Calculate potential temperature (theta) from hydrostatic pressure and water temperature data for thermodynamic analyses.
Strengths
- Data covers a specific 28-day research cruise providing a coherent temporal snapshot.
- Includes 14 distinct measured variables per sample/profile, enabling multi-variable analysis.
- Part of the CARINA international synthesis project, implying quality control and consistency checks.
Limitations
- Sample size is unknown, potentially limiting statistical power for regional analyses.
- Data is from a single cruise in 1995, representing a narrow temporal window and may not reflect current conditions.
- Geographic coverage is limited to specific tracks in the Gulf of St. Lawrence and North Atlantic Ocean.
