From July 18 to August 20, 1993, this dataset contains discrete sample and profile observations of carbon dioxide partial pressure, dissolved inorganic carbon, and related biogeochemical variables collected aboard the USCGC POLAR SEA in the North Greenland Sea. It was gathered by researchers from the Commonwealth Scientific and Industrial Research Organization, Universitat Kiel, and others using CTD and bottle instruments as part of the CARINA data synthesis project. The project aimed to produce an internally consistent data set for biogeochemical investigations, originally focused on the North Atlantic.
Use Cases
- Modeling ocean carbon uptake based on partial pressure of carbon dioxide and dissolved inorganic carbon measurements.
- Studying nutrient cycling in Arctic waters based on nitrate, nitrite, phosphate, and silicate data.
- Investigating marine biological productivity based on chlorophyll a, phaeopigments, and bacterial density.
- Analyzing water mass properties and circulation using potential temperature, salinity, and dissolved oxygen profiles.
- Tracing water masses and dating using tracer data like delta carbon-14, tritium, and helium isotopes.
Strengths
- Includes over 20 measured variables covering biological, chemical, and physical oceanographic properties.
- Data collection was part of the international CARINA synthesis project, which aimed for internal consistency.
- Covers a specific Arctic region (North Greenland Sea) during a defined summer period in 1993.
Limitations
- Last updated 1993-08-20 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
