Atlantic Ocean Carbon and Temperature Profiles from the EGEE-5 Cruise, 2007

Nathalie Lefèvre of Sorbonne University collected this dataset during cruise 35A820070606 from June to July 2007. It includes discrete sample and profile observations of dissolved inorganic carbon, alkalinity, salinity, and sea surface temperature from the Gulf of Guinea and North and South Atlantic Oceans. The data were gathered as part of the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program to quantify changes in ocean carbon storage and transport.

Use Cases

• Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and alkalinity measurements.
• Analyzing sea surface temperature variability in the Atlantic Ocean for climate studies.
• Calibrating satellite-derived salinity data with in-situ discrete sample measurements.
• Studying biogeochemical processes in the Gulf of Guinea using profile and chemical data.

Strengths

• Data collected as part of the systematic International CLIVAR Global Ocean Carbon and Repeat Hydrography Program.
• Includes four key oceanographic parameters: alkalinity, dissolved inorganic carbon, salinity, and sea surface temperature.
• Specific temporal coverage from 2007-06-06 to 2007-07-03.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to a single cruise in 2007.
