Ocean Surface pCO2 and Temperature Measurements from R/V Nathaniel B. Palmer, 2020-2021

Surface underway measurements of partial pressure of carbon dioxide (pCO2), sea surface temperature, salinity, and barometric pressure collected during R/V Nathaniel B. Palmer expeditions from 2020-01-28 to 2021-01-08. The dataset covers the Pacific Ocean, South Atlantic Ocean, and Southern Ocean. Data were collected by the National Oceanic and Atmospheric Administration using a Carbon dioxide (CO2) gas analyzer and shower head chamber equilibrator.

Use Cases

• Modeling ocean-atmosphere carbon dioxide flux based on partial pressure of carbon dioxide (pCO2) measurements.
• Analyzing sea surface temperature and salinity gradients across ocean basins.
• Calibrating satellite-derived ocean carbon data with in-situ underway measurements.
• Studying seasonal or regional variability in barometric pressure over the ocean surface.

Strengths

• Data collection spans multiple ocean basins (Pacific, South Atlantic, Southern) over a nearly one-year period (2020-01-28 to 2021-01-08).
• Specific instruments used for collection are documented: Carbon dioxide (CO2) gas analyzer and shower head chamber equilibrator.
• Dataset is hosted by a recognized authority, the National Oceanic and Atmospheric Administration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the ship's track and expedition schedule.
