Marcus G. Langseth Lines: Ocean Carbon and Sea Surface Measurements

Surface underway data from the R/V Marcus G. Langseth spans the Arctic Ocean, Beaufort Sea, Bering Sea, Caribbean Sea, and multiple U.S. National Marine Sanctuaries from 2010-05-07 to 2013-06-25. The dataset includes measurements of the partial pressure (or fugacity) of carbon dioxide in water, salinity, and sea surface temperature. It was collected by researchers from Columbia University's Lamont-Doherty Earth Observatory and the University of Colorado using carbon dioxide gas analyzers and equilibrators.

Use Cases

• Modeling ocean carbon uptake based on partial pressure of CO2 measurements.
• Analyzing sea surface temperature variability across diverse marine regions.
• Studying salinity gradients in coastal sanctuaries versus open ocean.
• Calibrating autonomous carbon dioxide measurement systems with field data.

Strengths

• Covers a wide geographic scope including the Arctic Ocean, Pacific, Atlantic, and seven U.S. National Marine Sanctuaries.
• Provides a multi-year time series from 2010 to 2013.
• Data collected using standardized instruments (CO2 gas analyzer, shower head chamber equilibrator).

Limitations

• Column names and row counts are not provided in any source, limiting immediate usability.
• Conflicting last updated timestamps (2013-06-25 vs. 2026-03-05) create uncertainty about data currency.
• License information is absent from all platform entries.
