July 26 to September 3, 1991 data collection from the Arctic Ocean aboard the ODEN research vessel. The dataset contains discrete sample and profile measurements of dissolved inorganic carbon, alkalinity, chlorofluorocarbons, nutrients, oxygen isotopes, temperature, and salinity. It was collected by researchers from Gothenburg University as part of the CARINA synthesis project for biogeochemical investigations.
Use Cases
- Calculate ocean acidification parameters like pH and pCO2 from DISSOLVED INORGANIC CARBON and TOTAL ALKALINITY measurements.
- Study Arctic Ocean ventilation rates and water mass age using CHLOROFLUOROCARBON-11 and CHLOROFLUOROCARBON-12 tracer concentrations.
- Model nutrient dynamics and biological productivity from NITRATE, phosphate, and silicate profiles.
- Analyze water mass properties and stratification using concurrent SALINITY, WATER TEMPERATURE, and Potential temperature (theta) data.
- Investigate oxygen cycling and processes using DISSOLVED OXYGEN and Delta Oxygen-18 isotope measurements.
Strengths
- Multivariate dataset includes 15+ chemical and physical parameters per observation.
- Data collected over a focused 40-day cruise in the Arctic Ocean during summer 1991.
- Part of the curated, internally consistent CARINA international data synthesis project.
Limitations
- Single cruise from 1991 provides a snapshot but lacks temporal continuity for trend analysis.
- Geographic coverage is limited to the specific cruise track of the ODEN vessel.
- Sample size and spatial resolution are constrained by discrete bottle sampling methods.
