Discrete sample and profile data collected from the HEALY vessel in the Arctic Ocean, Beaufort Sea, and Bering Sea from May 15 to June 23, 2004. The dataset includes measurements of dissolved inorganic carbon, alkalinity, nutrients, chlorophyll, and physical oceanographic variables. Data were collected by Louis A. Codispoti and James H. Swift as part of the CARINA international synthesis project.
Use Cases
- Modeling ocean acidification based on dissolved inorganic carbon and alkalinity measurements.
- Studying phytoplankton productivity based on chlorophyll a, phaeophytin, and photosynthetic active radiation data.
- Analyzing nutrient cycling in Arctic waters based on ammonium, nitrate, nitrite, phosphate, and silicate concentrations.
- Investigating water column structure and properties based on CTD-derived salinity, temperature, and hydrostatic pressure profiles.
Strengths
- Data covers a specific 40-day cruise period from 2004-05-15 to 2004-06-23.
- Includes 19 distinct measured variables spanning biological, chemical, optical, and physical properties.
- Part of the CARINA international synthesis project, aimed at producing an internally consistent dataset for biogeochemical investigations.
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 geographic bias inherent to the specific cruise track.
