Discrete chemical and physical measurements were collected from the METEOR research vessel during a 1994 cruise in the Davis Strait, Labrador Sea, and North Atlantic Ocean. The dataset includes dissolved inorganic carbon, chlorofluorocarbons, nutrients, temperature, salinity, and dissolved oxygen, gathered using CTD and bottle instruments. Data were collected by H. Thomas of CSIRO and J. Meincke as part of the CARINA/WOCE A01 project.
Use Cases
- Analyze dissolved inorganic carbon concentration trends with salinity and water temperature to study ocean acidification.
- Model chlorofluorocarbon (CFC-11, CFC-12) distributions using hydrostatic pressure and potential temperature to trace anthropogenic inputs.
- Correlate nutrient levels (nitrate, phosphate, silicate) with dissolved oxygen measurements to assess marine productivity.
- Calculate carbon system parameters using delta carbon-14 and helium isotopes (delta helium-3, tritium) for biogeochemical investigations.
Strengths
- Includes 15 distinct chemical and physical variables per measurement profile.
- Data is part of the CARINA synthesis project, ensuring internal consistency for biogeochemical studies.
- Provides specific temporal coverage from November 15 to December 19, 1994.
Limitations
- Sample size is unknown, potentially limiting statistical analysis.
- Data is from a single cruise in 1994, offering a snapshot rather than long-term trends.
- Geographic coverage is limited to specific regions (Davis Strait, Labrador Sea, North Atlantic) within the cruise track.
