R/V James Clark Ross Surface Carbon Dioxide Measurements

Surface underway data from the R/V James Clark Ross cruises span nine ocean regions, including the Arctic Ocean and Southern Ocean, from November 2012 to November 2013. The dataset contains measurements of the partial pressure of carbon dioxide in both the atmosphere and seawater, alongside sea surface temperature, salinity, and barometric pressure. These observations were collected using barometric pressure sensors and carbon dioxide gas analyzers.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure measurements.
• Assessing ocean acidification trends using surface water CO2 data.
• Validating regional carbon cycle models with in-situ sea surface temperature and salinity.
• Studying seasonal carbon dynamics across multiple ocean basins.

Strengths

• Data collection covers a wide geographic area across nine distinct ocean regions.
• Measurements are temporally coherent, covering a continuous, nearly year-long period from 2012-11-15 to 2013-11-08.
• Data originates from a recognized research vessel and is hosted by NOAA NCEI, indicating institutional credibility.

Limitations

• Column names and exact data structure are not provided in the available metadata, limiting immediate usability.
• There is a conflict in the 'last updated' metadata between platforms (2013-11-08 vs. 2026-03-06), creating uncertainty about data currency.
• Key metadata such as row count, file size, and specific license are unknown.
