Surface underway data from the CCGS Amundsen cruise in the Canadian Arctic Archipelago collected between July and September 2013 includes partial pressure of carbon dioxide (pCO2), barometric pressure, sea surface salinity, and sea surface temperature. The data were gathered using a CO2 gas analyzer and shower head chamber equilibrator for autonomous CO2 measurement. NOAA_NCEI provides this dataset through the nasa_earthdata platform.
Use Cases
- Modeling oceanic carbon uptake based on continuous pCO2 measurements.
- Analyzing Arctic sea surface temperature and salinity relationships.
- Studying atmospheric-sea surface interactions based on barometric pressure data.
Strengths
- Data covers a specific Arctic research cruise from 2013-07-26 to 2013-09-13.
- Includes key parameters for carbon cycle studies: pCO2, salinity, temperature, and barometric pressure.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2013-09-13 00:00:00; freshness should be verified.
- Row count is unknown, which may limit suitability assessment.
