NCEI Accession 0157293: Surface Underway Carbon Dioxide Measurements

NCEI Accession 0157293 contains surface underway data collected from the R/V EXPLORER OF THE SEAS across the North Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and other coastal regions from March 29, 2014, to January 4, 2015. The dataset includes measurements of the partial pressure of carbon dioxide in air and water, salinity, sea surface temperature, and barometric pressure, collected using a Carbon dioxide (CO2) gas analyzer. These data were collected by Rik Wanninkhof of NOAA's Atlantic Oceanographic and Meteorological Laboratory as part of the Volunteer Observing Ship (VOS) program.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure difference measurements.
• Analyzing spatial and temporal variability of surface ocean carbonate chemistry.
• Validating and calibrating regional ocean carbon models using in-situ salinity and temperature data.
• Studying the relationship between sea surface temperature and CO2 partial pressure in coastal waters.

Strengths

• Data covers a wide geographic area including six distinct ocean regions.
• Collection spans a continuous, nearly ten-month time period from 2014-03-29 to 2015-01-04.
• Measurements are derived from a specific, documented instrument: a Carbon dioxide (CO2) gas analyzer.

Limitations

• Key structural metadata is missing: row count, file size, and specific column names are unknown.
• The dataset's license information is not provided by any source.
• Conflicting 'last updated' dates exist between platforms (2015-01-04 vs. 2026-03-06), creating provenance uncertainty.
