NCEI Accession 0157261: Arctic Ocean Surface Carbon and Physical Data

NCEI Accession 0157261 contains surface underway data collected aboard the R/V Sikuliaq during a 2015 research cruise in the Arctic Ocean, Beaufort Sea, and Bering Sea. The dataset includes measurements of the partial pressure of carbon dioxide in seawater, sea surface temperature, salinity, and barometric pressure, collected using a carbon dioxide gas analyzer. It was produced by researchers from Columbia University's Lamont-Doherty Earth Observatory, the University of Colorado, and NOAA's Earth System Research Laboratory.

Use Cases

• Analyzing air-sea CO2 flux based on partial pressure measurements.
• Studying ocean acidification trends in the Arctic using carbon dioxide and salinity data.
• Correlating sea surface temperature with carbon dioxide concentrations in polar seas.
• Validating regional carbon cycle models with in-situ surface underway observations.

Strengths

• Data originates from a recognized research cruise (33BI20150813) conducted by major oceanographic institutions.
• Covers a specific three-week time range (2015-08-13 to 2015-09-02) in a critical polar region.
• Includes direct measurements of key carbon cycle variables (pCO2) using a dedicated gas analyzer.

Limitations

• The exact column structure, row count, and data format are unknown from the provided metadata.
• Metadata update dates conflict between sources (2015-09-02 vs. 2026-03-05), creating uncertainty about versioning.
• License information is not provided, restricting clarity on reuse permissions.
