Partial pressure (or fugacity) of carbon dioxide, salinity and other variables collected f

Lamont-Doherty Earth Observatory and NOAA ESRL collected surface underway chemical, meteorological, and physical data from the RV Nathaniel B. Palmer in the South Atlantic, South Pacific, and Southern Oceans. The dataset includes barometric pressure, partial pressure of carbon dioxide in water, salinity, and sea surface temperature from January 2010 to January 2011. Instruments used include a carbon dioxide gas analyzer and a shower head chamber equilibrator.

Use Cases

• Modeling 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 based on underway salinity and temperature data.
• Validating satellite-derived sea surface temperature products with in-situ measurements.

Strengths

• Data collected over a continuous 12-month period from 2010-01-02 to 2011-01-16.
• Includes multiple variable types: chemical (CO2), physical (SST, salinity), and meteorological (barometric pressure).
• Associated with a specific, documented research cruise (ID: 320620100102).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic bias inherent to the ship's track in the Southern Ocean.
