EGEE Cruises: Atlantic Ocean Carbon and Hydrographic Measurements

Gulf of Guinea, North Atlantic, and South Atlantic Ocean data from the EGEE research cruises aboard the ANTEA and L'ATALANTE vessels. The dataset contains surface underway, discrete sample, and profile measurements of carbon dioxide partial pressure, dissolved inorganic carbon, total alkalinity, salinity, and temperature from 2005 to 2007. It was collected using CTD, CO2 gas analyzer, and bottle instruments to study ocean carbon chemistry.

Use Cases

• Modeling air-sea CO2 fluxes based on partial pressure measurements in water and atmosphere.
• Analyzing ocean acidification trends using dissolved inorganic carbon and total alkalinity data.
• Calibrating satellite-derived sea surface temperature and salinity products with in-situ profile data.
• Studying spatial variability of hydrographic properties in the Gulf of Guinea from CTD profiles.

Strengths

• Multi-year temporal coverage from June 2005 to September 2007.
• Includes data from six distinct research cruises (EGEE-1 through EGEE-6).
• Combines multiple measurement types: surface underway, discrete samples, and vertical profiles.

Limitations

• Key metadata such as row count, file size, and specific license are unknown across all sources.
• Column names are not provided, limiting precise understanding of data structure.
• Conflicting author affiliation details: 'Universite Pierre et Marie Curie' vs. 'Sorbonne University (SU)'.
