NCEI Accession 0166631 contains underway measurements from the CGC Healy collected between June 30 and August 16, 2016. The data include barometric pressure, partial pressure of carbon dioxide in water, salinity, and sea surface temperature from the North Pacific Ocean, Bering Sea, Chukchi Sea, and Arctic Ocean. Instruments used include a CO2 gas analyzer and a shower head chamber equilibrator.
Use Cases
- Analyzing air-sea carbon dioxide flux based on partial pressure measurements.
- Studying ocean acidification trends using surface water pCO2 and salinity data.
- Modeling regional carbon budgets for the Bering and Chukchi Seas.
- Correlating sea surface temperature with carbon dioxide fugacity in underway data.
Strengths
- Data covers a specific 48-day expedition with a clear time range (2016-06-30 to 2016-08-16).
- Instruments are explicitly named (CO2 gas analyzer, shower head chamber equilibrator).
- Dataset is hosted on multiple authoritative platforms (Data.gov, NASA Earthdata).
Limitations
- Column names and exact row count are unknown from all sources.
- License information is not provided.
- The 'last updated' metadata conflicts between platforms (2026 vs. 2016).
