Surface Ocean CO2 Partial Pressure and Temperature Measurements from 2006

Surface underway observations of barometric pressure, partial pressure of carbon dioxide in water, salinity, and sea surface temperature were collected from the LAURENCE M. GOULD research vessel in the South Atlantic, South Pacific, and Southern Oceans. The data were gathered between January 1 and December 27, 2006, using carbon dioxide gas analyzers and equilibrators. Stewart C. Sutherland, Taro Takahashi of Lamont-Doherty Earth Observatory, and Colm Sweeney of NOAA ESRL collected these data as part of the VOS_LMG_Lines_2006 dataset.

Use Cases

• Modeling ocean-atmosphere carbon dioxide flux based on partial pressure measurements.
• Analyzing sea surface temperature and salinity relationships in the Southern Ocean.
• Studying seasonal carbon dynamics in polar oceans based on the 2006 time series.
• Calibrating autonomous carbon dioxide measurement instruments using the described methodology.

Strengths

• Data collection spans nearly a full year, from 2006-01-01 to 2006-12-27.
• Measurements include four key oceanographic variables: BAROMETRIC PRESSURE, Partial pressure of CO2, SALINITY, and SEA SURFACE TEMPERATURE.
• Data provenance is clearly stated, citing specific researchers from 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 single vessel's track in the Southern Ocean.
