Oden_77DNOSO_2006: Surface Ocean Carbon and Temperature Measurements

Surface underway data from the research vessel ODEN covers a 13-day period from December 14 to 26, 2006, in the South Atlantic, South Pacific, and Southern Oceans. The dataset includes measurements of the partial pressure of carbon dioxide in seawater, salinity, and sea surface temperature. These observations were collected using a CO2 gas analyzer and a shower head equilibrator by researchers from the Norwegian Polar Institute.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure measurements.
• Analyzing correlations between sea surface temperature and carbon dioxide fugacity.
• Studying oceanographic conditions in the Southern Ocean during the austral summer.
• Validating biogeochemical models of the carbon cycle in high-latitude oceans.

Strengths

• Data collection uses specific, named instruments (CO2 gas analyzer, shower head chamber equilibrator).
• Clear provenance with identified principal investigators (Agneta Fransson, Melissa Chierici) and institution (Norwegian Polar Institute).
• Well-defined spatial coverage across three major ocean basins south of 60 degrees South.

Limitations

• Critical metadata is missing, including row count, file size, specific column names, and data license.
• Conflicting 'last updated' dates (2006-12-26 vs. 2026-03-06) create uncertainty about metadata maintenance.
• Dataset documentation is sparse, lacking details on data processing, quality flags, or measurement uncertainty.
