Surface Ocean Carbon Dioxide and Meteorological Measurements from RV Polarstern, 2016

Surface underway data collected from the RV Polarstern in the North Atlantic Ocean, South Atlantic Ocean, South Pacific Ocean, and Southern Oceans from 2016-02-20 to 2016-05-08. The data include barometric pressure, partial pressure of carbon dioxide in air and water, wind direction, and wind speed. These data were collected by researchers from the Alfred Wegener Institute for Polar and Marine Research and Groningen University.

Use Cases

• Calculate air-sea carbon dioxide flux based on partial pressure measurements in air and water.
• Analyze correlations between wind speed and carbon dioxide exchange rates.
• Validate or calibrate ocean carbon cycle models using in-situ surface observations.
• Study regional variability of surface ocean carbon dioxide across multiple ocean basins.

Strengths

• Data spans a 79-day period from February to May 2016.
• Covers four distinct ocean regions, including the Southern Oceans south of 60 degrees.
• Includes directly measured chemical and meteorological variables relevant for carbon flux studies.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2016-05-08 00:00:00; freshness should be verified.
• Row count is unknown, which may limit suitability assessment.
