Surface Carbon Dioxide Measurements from the North Atlantic, 2013

CEFAS ENDEAVOUR collected these surface underway chemical and physical measurements in the North Atlantic Ocean and adjacent seas during a 23-day cruise from September to October 2013. Data include partial pressure of carbon dioxide in both air and water, salinity, sea surface temperature, and barometric pressure. David J. Pearce and Naomi Greenwood of the Centre for Environment, Fisheries and Aquaculture Science gathered this data using CO2 gas analyzers and equilibrators.

Use Cases

• Modeling air-sea CO2 flux based on the partial pressure difference between water and atmosphere.
• Analyzing regional carbon dynamics based on surface CO2, salinity, and temperature measurements.
• Calibrating or validating satellite-derived sea surface temperature or salinity products.
• Studying seasonal or spatial variability in marine carbonate chemistry within the North Atlantic region.

Strengths

• Data includes simultaneous measurements of CO2 in both air and water, enabling flux calculations.
• Coverage spans multiple bodies of water including the North Sea, Irish Sea, and English Channel over a defined 23-day period.
• Specific instruments (CO2 gas analyzer, shower head equilibrator) are documented in the metadata.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic and temporal bias inherent to a single research cruise in autumn 2013.
