Surface underway measurements of fugacity of carbon dioxide (fCO2), sea surface salinity, temperature, and other parameters were collected during six NOAA Ship Oscar Dyson cruises. The cruises occurred in the North Pacific Ocean, Gulf of Alaska, Bering Sea, Chukchi Sea, and Arctic Ocean from February to October 2020. This effort was conducted in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program.
Use Cases
- Modeling ocean carbon uptake based on fugacity of carbon dioxide (fCO2) measurements.
- Analyzing seasonal variability in sea surface temperature and salinity across northern ocean basins.
- Studying spatial gradients of ocean acidification parameters from coastal to open ocean regions.
- Calibrating satellite-derived sea surface temperature products with in-situ underway observations.
- Investigating the impact of Arctic Ocean conditions on surface carbon dioxide fugacity.
Strengths
- Data covers six distinct research cruises spanning from February to October 2020.
- Geographic coverage includes multiple northern ocean basins: North Pacific, Gulf of Alaska, Bering Sea, Chukchi Sea, and Arctic Ocean.
- Measurements are surface underway, likely providing continuous spatial coverage along cruise tracks.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified; the last metadata update is listed as 2026-03-05.
