Southern Ocean pCO2 Measurements from ARSV Laurence M. Gould in 2020

Surface underway measurements of partial pressure of carbon dioxide (pCO2) were collected aboard the Antarctic Research and Supply Vessel Laurence M. Gould during expeditions in 2020. The dataset includes atmospheric and seawater pCO2, sea surface salinity, sea surface temperature, and barometric pressure from the Southern Ocean, South Pacific Ocean, Drake Passage, and South Atlantic Ocean. Data were gathered using a carbon dioxide gas analyzer and a shower head chamber equilibrator.

Use Cases

• Calculating air-sea carbon dioxide flux based on partial pressure measurements.
• Monitoring ocean acidification trends in the Southern Ocean using seawater pCO2 and salinity.
• Correlating atmospheric pressure with surface carbon dioxide levels for meteorological studies.
• Assessing seasonal variability of sea surface temperature and carbon dioxide in the Drake Passage.

Strengths

• Data collection spans a defined time range from 2020-02-16 to 2020-12-27.
• Includes simultaneous measurements of both atmospheric and seawater carbon dioxide partial pressure.
• Data originates from a recognized research vessel (ARSV Laurence M. Gould) and is managed by NOAA NCEI.

Limitations

• Column names and exact data structure are unknown.
• Row count and dataset size are not specified.
• Last updated metadata dates conflict between sources (2026-03-05 and 2020-12-27).
