Lisa A. Miller and colleagues collected over 35 years of oceanographic data across the Arctic Ocean and adjacent seas. These data include dissolved inorganic carbon, pH, alkalinity, chlorophyll, and nutrients from 34 distinct research cruises. Measurements were taken using CTD and bottle instruments on vessels like the Amundsen and Louis S. St-Laurent.
Use Cases
- Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements.
- Studying marine primary productivity based on chlorophyll a and nutrient data.
- Analyzing water mass properties and circulation based on salinity, temperature, and dissolved oxygen profiles.
- Investigating organic matter cycling based on particulate and dissolved organic carbon and nitrogen data.
Strengths
- Data spans 35 years from 1974-08-11 to 2009-10-15.
- Includes measurements from 34 distinct research cruises across multiple Arctic seas.
- Contains over 20 specific chemical and physical variables, including key carbon cycle parameters.
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 research vessel tracks.
