Marcus G. Langseth Ship Surface Carbon and Oceanographic Data

Multiple research cruises aboard the R/V Marcus G. Langseth collected surface underway measurements of carbon dioxide partial pressure, salinity, and sea surface temperature across global oceans from 2011 to 2015. Data from four distinct voyages cover the Arctic, Pacific, Atlantic, and Mediterranean seas, including several U.S. National Marine Sanctuaries. This dataset supports the study of ocean carbon uptake, acidification, and air-sea gas exchange dynamics.

Use Cases

• Tracking ocean carbon uptake and acidification trends based on partial pressure of carbon dioxide measurements.
• Analyzing air-sea gas exchange dynamics using concurrent barometric pressure and sea surface temperature data.
• Calibrating and validating satellite-derived sea surface salinity and temperature products.
• Studying regional carbon flux variability in protected marine sanctuaries and major ocean basins.

Strengths

• Data collection spans multiple years (2011-2015) and distinct global ocean voyages.
• Measurements are taken from a dedicated research vessel using standardized instruments like CO2 gas analyzers and equilibrators.
• Geographic coverage is broad, including the Arctic, Pacific, Atlantic, and Mediterranean seas.

Limitations

• Key metadata such as row counts, file size, specific column names, and license information are missing from all platform entries.
• Conflicting 'last updated' timestamps exist for the same dataset (e.g., 2013-06-25 vs. 2026-03-05).
• Documentation appears sparse, with no detailed data dictionary or instrument calibration notes provided.
