Gulf of Maine Coastal Carbon Dioxide and Surface Conditions, 2017

North Atlantic Ocean and Gulf of Maine surface underway and coastal time series data from the R/V Gulf Challenger in 2017. The dataset includes measurements of air and sea surface temperature, barometric pressure, sea surface salinity, and the partial pressure of carbon dioxide in both the atmosphere and water. Data were collected using a carbon dioxide gas analyzer and a shower head chamber equilibrator.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure (pCO2) measurements in atmosphere and water.
• Analyzing seasonal variability of surface ocean chemistry from time series coastal observations.
• Correlating sea surface temperature and salinity with carbon dioxide fugacity in the Gulf of Maine.
• Validating regional ocean carbon models using underway meteorological and chemical data.

Strengths

• Provides a continuous time series from March to November 2017, capturing seasonal changes.
• Includes directly measured fugacity of CO2 in both air and water, a key variable for flux calculations.
• Data is hosted on multiple authoritative platforms (NASA EarthData, Data.gov), indicating curation and importance.

Limitations

• Column names and dataset size (row count, file size) are not provided in any source, limiting immediate usability.
• Conflicting 'last updated' dates (2026-03-06 vs. 2017-11 13) create uncertainty about post-collection processing.
• Documentation is sparse, with no explicit license, author, or detailed instrument metadata listed.
