Surface Underway Ocean Carbon and Meteorological Measurements

NCEI Accession 0157277 contains surface underway observations of carbon dioxide fugacity and related variables from the vessel Cap San Lorenzo. The data were collected in the North Atlantic Ocean, South Atlantic Ocean, Mediterranean Sea, English Channel, and Strait of Gibraltar from November 15 to 19, 2014. Measurements include barometric pressure, sea surface temperature, salinity, and the partial pressure of carbon dioxide in both the atmosphere and surface water.

Use Cases

• Calculating air-sea CO2 flux based on measured fugacity gradients.
• Analyzing spatial variability of surface ocean pCO2 across multiple ocean basins.
• Validating satellite-derived sea surface temperature and salinity products with in-situ data.
• Studying short-term meteorological influences on surface ocean carbon chemistry.

Strengths

• Data collection is attributed to specific researchers from recognized institutions (IRD, Sorbonne University).
• The dataset includes direct, concurrent measurements of atmospheric and aquatic carbon dioxide fugacity, a key pair for flux calculations.
• It covers a transect through five distinct marine regions over a five-day period.

Limitations

• The exact number of rows and data file size are unknown, preventing an assessment of dataset scale.
• Column names are not provided, limiting understanding of the data structure.
• The license under which the data is available is unspecified.
