MN COLIBRI Cruise 2009: Surface Ocean Carbon and Meteorological Data

Surface underway data from the MN COLIBRI vessel tracks carbon dioxide exchange and ocean conditions across the Mediterranean Sea, North Atlantic Ocean, and North Sea from June to September 2009. The dataset includes measurements of atmospheric and aquatic partial pressure of carbon dioxide, sea surface temperature, salinity, and barometric pressure. It was collected by researchers from the French National Research Institute for Sustainable Development and Sorbonne University as part of the VOS_Colibri_Line_2009 project.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure measurements in water and atmosphere.
• Analyzing regional variability in sea surface temperature and salinity across multiple basins.
• Validating satellite-derived ocean surface data with in-situ underway measurements.
• Studying seasonal carbon cycle dynamics in the Mediterranean Sea during summer.

Strengths

• Data collected over a wide geographic area covering eight distinct sea regions.
• Time series spans 85 days in 2009, providing continuous summer observations.
• Includes direct measurements from specialized instruments like CO2 gas analyzers and thermosalinographs.

Limitations

• Column names and row counts are not provided by any source, limiting data structure transparency.
• Conflicting last-update timestamps exist between platforms (2009-09-07 vs. 2026-03-05).
• License information is not specified, restricting clarity on reuse permissions.
