Partial pressure of carbon dioxide, temperature, salinity and other variables collected from surface underway coastal observations from the ship of opportunity (SOOP) Offshore Supply Ship Atlantic Condor in the North Atlantic Ocean, from 2018-02-02 to 2018-11-26 (NCEI Accession 0184868)

From February to November 2018, this dataset contains surface underway measurements of carbon dioxide partial pressure, temperature, salinity, and other variables collected from the Offshore Supply Ship Atlantic Condor in the North Atlantic Ocean. It includes data on sea surface temperature, salinity, mole fraction of carbon dioxide, and oxygen. The data were collected by NOAA's National Centers for Environmental Information using instruments like a flat membrane equilibrator, conductivity sensor, and oxygen optode.

Use Cases

• Analyze the relationship between sea surface temperature and the partial pressure of carbon dioxide (pCO2) to study ocean-atmosphere gas exchange.
• Model sea surface salinity variations against conductivity sensor readings for water mass characterization.
• Investigate temporal trends in the mole fraction of carbon dioxide (xCO2) from February to November 2018.
• Correlate equilibrator temperature and pressure readings with calculated pCO2 values for sensor performance validation.
• Assess coastal water properties by combining oxygen optode measurements with salinity and temperature data.

Strengths

• Data collection spans a 9-month period from 2018-02-02 to 2018-11-26.
• Includes multiple concurrent physical and chemical variables like pCO2, temperature, salinity, and oxygen.
• Collected via a ship of opportunity, providing real-world surface underway observations.

Limitations

• Limited to a single vessel's track in the North Atlantic Ocean, restricting spatial representativeness.
• The dataset covers less than one full annual cycle, limiting seasonal analysis.
• Specific sample size, row count, and data resolution are unknown.
