Southern Ocean Carbon Dioxide and Sea Surface Measurements from 1999-2000

Surface underway measurements of carbon dioxide partial pressure, salinity, and sea temperature collected aboard the R/V Nathaniel B. Palmer across the Southern Oceans from March 1999 to February 2000. Stewart C. Sutherland, Taro Takahashi of Lamont-Doherty Earth Observatory, and Colm Sweeney of NOAA ESRL gathered these chemical, meteorological, and physical data. The dataset includes barometric pressure, sea surface temperature, and salinity alongside CO2 measurements.

Use Cases

• Modeling air-sea carbon dioxide exchange based on partial pressure (fugacity) measurements.
• Analyzing correlations between sea surface temperature and carbon dioxide concentrations.
• Studying seasonal or spatial variability in Southern Ocean salinity and barometric pressure.
• Validating global carbon cycle models with in-situ underway observation data.

Strengths

• Data collection spans nearly a full year from 1999-03-06 to 2000-02-10.
• Includes simultaneous measurements of CO2 fugacity, salinity, temperature, and barometric pressure.
• Collected by recognized institutions (Lamont-Doherty Earth Observatory and NOAA ESRL).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific cruise track of the R/V Nathaniel B. Palmer.
