Chemical and physical data collected from the POLARSTERN research vessel in the Arctic Ocean from July to September 1996. The dataset includes measurements for dissolved inorganic carbon, alkalinity, pH, chlorofluorocarbons, and nutrients. It was collected by researchers from the Alfred Wegener Institute and University of Gothenburg as part of the CARINA data synthesis project.
Use Cases
- Modeling ocean carbon uptake based on dissolved inorganic carbon and alkalinity measurements
- Analyzing historical chlorofluorocarbon (CFC-11, CFC-12) concentrations as ocean tracers
- Studying nutrient dynamics (nitrate, phosphate, silicate) in Arctic waters
- Investigating relationships between water temperature, salinity, and pH profiles
Strengths
- Data collected during a specific cruise (06ARKXII/AQN12) over a defined period (1996-07-12 to 1996-09-06)
- Includes multiple key variables for carbon system studies (DIC, alkalinity, pH, CFCs)
- Part of the CARINA international synthesis project, suggesting quality control and integration efforts
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data may reflect temporal bias inherent to a single cruise in 1996
