North Atlantic Ocean data from a 1993 research cruise includes measurements for alkalinity, dissolved oxygen, nitrate, nitrite, phosphate, silicate, salinity, water temperature, pH, and hydrostatic pressure. The dataset was collected by researchers F. Pérez and J.M. Cabanas during the CARINA/29CS19930510 expedition from May 10 to June 1, 1993. Instruments used were CTD and bottle samplers aboard the vessel CORNIDE DE SAAVEDRA.
Use Cases
- Modeling ocean acidification by analyzing correlations between pH, alkalinity, and dissolved oxygen measurements.
- Studying nutrient cycles through time-series analysis of nitrate, nitrite, phosphate, and silicate concentrations.
- Calibrating oceanographic models using concurrent profiles of salinity, water temperature, and hydrostatic pressure.
- Investigating carbon system dynamics by using alkalinity data as part of the CARINA synthesis project.
Strengths
- Includes 11 key chemical and physical variables for ocean biogeochemistry studies.
- Data is part of the CARINA international synthesis project, aimed at producing an internally consistent dataset.
- Provides discrete sample and profile data from a specific research cruise over a 23-day period.
Limitations
- Single cruise from 1993 provides limited temporal coverage for long-term trend analysis.
- Geographic scope is restricted to the specific cruise track in the North Atlantic Ocean.
- Sample size and row count are unknown, limiting assessment of statistical robustness.
