Surface Ocean Carbon Dioxide Measurements from the Southern Ocean, 2002

LAURENCE M. GOULD collected surface underway measurements of atmospheric and aquatic carbon dioxide partial pressure in the Southern Oceans from March to December 2002. The dataset includes barometric pressure, salinity, and sea surface temperature alongside the CO2 readings. Taro Takahashi of Lamont-Doherty Earth Observatory, Colm Sweeney and Tim Newberger of NOAA ESRL, and David R. Munro of University of Colorado - Boulder contributed to this data collection under cruise ID 33LG20020323.

Use Cases

• Modeling ocean-atmosphere CO2 flux based on partial pressure measurements in water and air.
• Analyzing the relationship between sea surface temperature and carbon dioxide solubility in the Southern Ocean.
• Studying seasonal carbon cycle variations in high-latitude oceans based on the 2002 time series.
• Calibrating or validating autonomous carbon dioxide measurement instruments using the described equilibrator and analyzer data.

Strengths

• Data collected over a 9-month period in 2002, providing a seasonal time series.
• Includes simultaneous measurements of CO2 in both the atmosphere and seawater, enabling flux calculations.
• Associated with a specific research cruise (33LG20020323) and collected by recognized institutions (LDEO, NOAA ESRL, CU-B).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single year and vessel, which may limit generalizability.
