CARINA project data includes dissolved inorganic carbon, chlorofluorocarbons, nitrate, phosphate, salinity, and water temperature measurements collected from the Hudson research vessel in the North Atlantic Ocean during October and November 1994. Scientists E. Peter Jones and R.A. Clarke of the Bedford Institute of Oceanography gathered these chemical and physical profiles using CTD and bottle instruments. This dataset is part of an international synthesis effort for biogeochemical investigations.
Use Cases
- Analyze the relationship between dissolved inorganic carbon (DIC) and potential temperature (theta) across different hydrostatic pressure levels.
- Model the co-distribution of chlorofluorocarbon-11 (CFC-11) and chlorofluorocarbon-12 (CFC-12) with salinity and dissolved oxygen measurements.
- Study nutrient cycles by correlating nitrate and phosphate concentrations with silicate levels at various sampling depths.
- Assess carbon system parameters by examining DIC alongside water temperature and salinity profiles from bottle samples.
Strengths
- Includes 13 distinct chemical and physical variables, such as multiple chlorofluorocarbon species and inorganic carbon.
- Data collected during a dedicated research cruise over a 29-day period in a defined ocean region.
- Part of the CARINA merged data set, an international project focused on internal consistency for carbon studies.
Limitations
- Data is from a single cruise in 1994, providing a snapshot rather than a long-term time series.
- Specific row count, sample size, and geographic coordinates within the North Atlantic are unknown.
- Data is over 30 years old, limiting its relevance for studying current ocean conditions.
