Discrete sample and profile data from the North Atlantic Ocean collected aboard the DARVIN during cruise CARINA/74AB19900528 from May 28 to June 15, 1990. Andrew Watson of the Plymouth Marine Laboratory gathered measurements using CTD and bottle instruments. The data includes dissolved inorganic carbon, dissolved oxygen, nitrate, phosphate, silicate, salinity, and water temperature.
Use Cases
- Analyze dissolved inorganic carbon concentration alongside salinity and temperature to study carbon system variability.
- Model relationships between nitrate, phosphate, silicate, and dissolved oxygen for nutrient cycling investigations.
- Use hydrostatic pressure and potential temperature (theta) profiles to validate oceanographic models.
- Compare nitrite and nitrate levels to assess nitrogen transformation processes.
Strengths
- Includes 10 specific chemical and physical variables: dissolved inorganic carbon, oxygen, nitrate, nitrite, phosphate, silicate, salinity, temperature, potential temperature, and hydrostatic pressure.
- Data collected during a defined 19-day research cruise, providing temporal consistency.
- Part of the CARINA synthesis project, aimed at producing an internally consistent data set for biogeochemical studies.
Limitations
- Limited temporal coverage (single cruise in 1990), not suitable for long-term trend analysis.
- Geographic scope is restricted to a specific North Atlantic Ocean region during the cruise.
- Sample size and row count are unknown, potentially limiting statistical power.
