VOS_Colibri_Line_2016: Ship-Based pCO2 Measurements in the North Atlantic

2016 surface underway measurements from the MN Colibri vessel in the English Channel and North Atlantic Ocean. The dataset includes barometric pressure, partial pressure of carbon dioxide in the atmosphere and water, sea surface salinity, and sea surface temperature. Data were collected using a Carbon dioxide (CO2) gas analyzer as part of the Ships of Opportunity (SOOP) program.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure measurements.
• Analyzing seasonal variability of surface ocean pCO2 along a ship transect.
• Validating satellite-derived sea surface salinity and temperature products.
• Studying the relationship between atmospheric pressure and oceanic carbon parameters.

Strengths

• Data collected via a dedicated instrument (Carbon dioxide gas analyzer) for high-precision pCO2 measurement.
• Covers a specific geographic region (English Channel and North Atlantic Ocean) and temporal period (2016).
• Cross-platform presence on NASA Earthdata and Data.gov indicates recognized importance and curation.

Limitations

• Column names and exact data structure are not provided in any source description.
• Conflicting 'last updated' dates exist (2016-09-04 and 2026-03-05), creating uncertainty about metadata freshness.
• Key metadata such as row count, file size, and license are uniformly absent.
