Pelican Vessel Carbon Dioxide Measurements from Gulf of Mexico

2006 measurements of partial pressure of carbon dioxide (PCO2) collected onboard the Pelican research vessel off the southern coast of Louisiana in the Gulf of Mexico. The dataset is hosted by the OB_DAAC organization and is available on multiple platforms, including NASA EarthData and Data.gov. It provides in-situ oceanographic data for a specific time and region.

Use Cases

• Analyzing spatial and temporal patterns of oceanic carbon dioxide partial pressure (PCO2).
• Correlating PCO2 levels with other oceanographic variables like temperature and salinity.
• Studying air-sea gas exchange and carbon cycling in the Gulf of Mexico.
• Providing ground-truth data for satellite-derived ocean chemistry models.

Strengths

• Data originates from a dedicated research vessel (Pelican), indicating controlled collection methods.
• Available on multiple authoritative platforms (NASA EarthData, Data.gov), signaling importance and validation.
• Covers a specific, focused geographic area (Gulf of Mexico off Louisiana) and year (2006).

Limitations

• Critical metadata is missing, including column names, row count, and file size across all sources.
• Sources conflict on license details, with some specifying 'other-license-specified' and others listing 'None'.
• The dataset's age (2006) may limit applicability to current climate studies without more recent companion data.
