VOS_LMG_Lines_2004: Surface Ocean Carbon and Temperature Measurements

NCEI Accession 0144538 and 0148768 contain surface underway data collected from the RV Laurence M. Gould during 2004. The dataset includes measurements of the partial pressure of carbon dioxide in air and water, sea surface temperature, salinity, and barometric pressure across the Caribbean Sea, North and South Pacific, South Atlantic, and Southern Oceans. Data were collected by researchers from Columbia University's Lamont-Doherty Earth Observatory, NOAA ESRL, and the University of Colorado using CO2 gas analyzers and equilibrators.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure differentials.
• Monitoring ocean acidification trends in the Southern Ocean.
• Validating satellite-derived sea surface temperature and salinity products.
• Studying seasonal carbon cycle dynamics in polar and sub-polar regions.

Strengths

• Data collected across a wide geographic range, including the Southern Ocean (>60°S).
• Includes co-located atmospheric and aquatic CO2 partial pressure measurements.
• Associated with a specific research cruise (ID: 33LG20040101/33LG20040102).

Limitations

• Column names and exact row counts are not provided in any source.
• Sources conflict on the exact start date (2004-01-01 vs. 2004-01-02) and principal investigators.
• Metadata on license, data size, and detailed provenance is sparse.
