MN COLIBRI Cruise: Ocean and Atmospheric CO2 Measurements

Surface underway data from the MN COLIBRI vessel includes measurements of barometric pressure, partial pressure of carbon dioxide in air and water, salinity, and sea surface temperature. The data were collected in the English Channel and North Atlantic Ocean over a 10-day period from January 7 to 17, 2011. Researchers Denis Diverrès and Nathalie Lefèvre gathered these observations as part of the VOS_Colibri_Line_2011 dataset.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure measurements in the atmosphere and water.
• Analyzing the relationship between sea surface temperature and carbon dioxide solubility.
• Validating regional ocean carbon cycle models using in-situ salinity and temperature data.
• Monitoring temporal variability of surface ocean carbon parameters along a ship transect.

Strengths

• Data includes simultaneous measurements of atmospheric and aquatic carbon dioxide partial pressure, enabling flux calculations.
• Collection period is precisely defined as a 10-day cruise from 2011-01-07 to 2011-01-17.
• Instruments are explicitly listed, including a barometric pressure sensor, CO2 gas analyzer, equilibrator, and thermosalinographs.

Limitations

• The exact column names and the total number of rows are not provided by any source.
• Metadata conflicts exist: one source lists a last updated date in 2026, while another lists 2011.
• Dataset size and license information are uniformly reported as unknown or null across all platforms.
