Coastal Carbon Dioxide Flux Measurements from CEFAS Endeavour Cruises

Surface underway measurements from the CEFAS ENDEAVOUR research vessel track carbon dioxide exchange between the ocean and atmosphere in the coastal waters of the Bristol Channel, English Channel, Irish Sea, St. George's Channel, and the North Sea. The dataset includes partial pressure (fugacity) of CO2 in air and water, sea surface temperature, salinity, and barometric pressure, collected using specialized gas analyzers and equilibrators. These observations support research on ocean acidification and carbon cycling in dynamic, temperate shelf seas.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure differences.
• Assessing seasonal and spatial variability in coastal ocean acidification using pCO2 and salinity data.
• Validating regional carbon cycle models with in-situ sea surface temperature and CO2 measurements.
• Studying the relationship between meteorological conditions and gas exchange using barometric pressure data.

Strengths

• Data collected by named principal investigators (Dr. Naomi Greenwood, Dr. David J. Pearce) from a recognized research institution (Cefas).
• Covers multiple distinct research cruises across several years, providing temporal and spatial coverage.
• Measurements obtained using standardized instruments (CO2 gas analyzer, shower head chamber equilibrator).

Limitations

• Key metadata such as row counts, file size, and specific column names are unavailable across all sources.
• Conflicting last-update dates exist for the same NCEI accession (0157267) between platforms.
• License information is not provided, restricting clarity on reuse terms.
