Arctic Ocean Surface Carbon Dioxide Measurements from 2014

Surface underway observations from the HEALY research vessel in the Arctic Ocean and North Pacific from May to August 2014. The dataset includes measurements of partial pressure of carbon dioxide in water, salinity, sea surface temperature, and barometric pressure, collected by researchers from Lamont-Doherty Earth Observatory and NOAA ESRL.

Use Cases

• Analyze the relationship between partial pressure of carbon dioxide in water and sea surface temperature across Arctic and Pacific waters.
• Study spatial and temporal variations in salinity and barometric pressure from surface underway observations.
• Model carbon flux using partial pressure of carbon dioxide data alongside sea surface temperature and salinity measurements.
• Investigate correlations between barometric pressure and other oceanographic variables in coastal and open ocean regions.

Strengths

• Data collected over a defined 4-month period from May to August 2014.
• Includes key ocean carbon cycle variables: partial pressure of CO2, salinity, and sea surface temperature.
• Spatial coverage spans multiple regions including the Arctic Ocean, Beaufort Sea, Bering Sea, and Gulf of Alaska.
• Data originates from established research institutions (Lamont-Doherty Earth Observatory, NOAA ESRL).

Limitations

• Unknown sample size or row count prevents assessment of statistical power.
• Limited temporal scope to a single summer season, missing annual cycles.
• Geographic coverage is specific to the HEALY vessel's 2014 cruise track, not a global survey.
