CARINA project data from a December 1983 cruise captured 11 key oceanographic variables, including dissolved oxygen, nitrate, salinity, pH, and total alkalinity. Researchers from the Commonwealth Scientific and Industrial Research Organization and Instituto de Investigaciones Marinas de Vigo collected these discrete sample and profile observations. Measurements were taken in the North Atlantic Ocean over a 12-day period using CTD and bottle instruments.
Use Cases
- Calculate ocean acidification metrics by correlating pH and total alkalinity (TA) with water temperature and salinity.
- Model nutrient distributions by analyzing nitrate, nitrite, phosphate, and silicate concentrations across sampling depths.
- Study water mass characteristics by examining profiles of potential temperature (theta), salinity, and hydrostatic pressure.
- Assess marine biogeochemical processes by investigating relationships between dissolved oxygen and nutrient variables.
Strengths
- Includes 11 distinct biogeochemical and physical variables per observation.
- Data is part of the CARINA synthesis project, designed for internal consistency in carbon system studies.
- Temporal coverage is precisely defined for a 12-day cruise in December 1983.
Limitations
- Sample size and row count are unknown, potentially representing a limited geographic snapshot.
- Data is from 1983 and may not reflect current ocean conditions.
- The affiliation for one contributor (F. Fraga) is listed as unknown, affecting provenance clarity.
