MN COLIBRI 2015-2016: Surface Ocean CO2, Salinity, and Meteorological Measurements

From February 26, 2015, to January 5, 2016, the vessel MN COLIBRI collected surface underway observations in the Mediterranean Sea, North Atlantic Ocean, and adjacent waters. The dataset includes measurements of the partial pressure of carbon dioxide in both the atmosphere and surface water, alongside sea surface temperature, salinity, and barometric pressure, collected using a CO2 gas analyzer. These data were contributed by researchers from the French National Research Institute for Sustainable Development and Sorbonne University as part of the VOS_Colibri_Line_2015 project.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure measurements in water and atmosphere.
• Analyzing seasonal variability of surface ocean carbon parameters across multiple sea basins.
• Correlating sea surface temperature and salinity with carbon dioxide fugacity.
• Validating regional ocean carbon cycle models with in-situ underway data.

Strengths

• Provides continuous surface measurements over a nearly 11-month time range (2015-02 26 to 2016-01-05).
• Data covers multiple, specific geographic regions including the Alboran Sea, Balearic Sea, and Strait of Gibraltar.
• Collected as part of a defined research project (VOS_Colibri_Line_2015) with identified principal investigators.

Limitations

• Column names and precise data structure are not provided in the available metadata.
• Conflicting 'last updated' dates (2026-03-06 vs. 2016-01-05) create uncertainty about metadata maintenance.
• No information on data volume (rows, size) or licensing terms is available.
