Southern Ocean Carbon Dioxide Measurements from ARSV Laurence M. Gould

NOAA NCEI Accession 0184338 contains surface underway measurements of partial pressure of carbon dioxide in the atmosphere and water, alongside sea surface salinity, temperature, and barometric pressure. Data were collected by the Antarctic Research and Supply Vessel Laurence M. Gould in the Southern Ocean, Drake Passage, and South Atlantic Ocean from February 2018 to February 2019 using a CO2 gas analyzer and equilibrator.

Use Cases

• Calculating ocean carbon uptake based on partial pressure (or fugacity) of carbon dioxide in water
• Analyzing sea surface temperature and salinity correlations with atmospheric CO2 levels
• Modeling regional carbon budgets in the Drake Passage using time-series underway data
• Studying barometric pressure effects on surface CO2 measurements

Strengths

• Data covers a specific, continuous time range from 2018-02-16 to 2019-02-11
• Includes direct measurements from dedicated scientific instruments (CO2 gas analyzer and equilibrator)
• Dataset is hosted and maintained by authoritative organizations (NOAA NCEI)

Limitations

• Column names and exact data structure are unknown from all provided sources
• Metadata conflicts: last updated date is reported as both 2019-02-11 and 2026-03-05
• No license information is provided
