Healy 2018: Surface Ocean pCO2 and Conditions in the Arctic and North Pacific

Surface underway data from the USCGC Healy cruise provides measurements of partial pressure of carbon dioxide (pCO2) in water, sea surface salinity, sea surface temperature, and barometric pressure. The data were collected autonomously using a CO2 gas analyzer and equilibrator across the North Pacific Ocean, Gulf of Alaska, Bering Sea, Chukchi Sea, and Arctic Ocean. This time-series dataset covers a four-month period from June to October 2018.

Use Cases

• Tracking seasonal changes in oceanic pCO2 based on continuous underway measurements.
• Analyzing air-sea CO2 flux dynamics using concurrent pCO2 and barometric pressure data.
• Correlating sea surface temperature and salinity with carbon dioxide partial pressure.
• Studying spatial gradients of marine carbon parameters across Arctic and sub-Arctic seas.

Strengths

• Data collection spans a significant four-month time range from 2018-06-20 to 2018-10-18.
• Covers a wide geographic area including multiple distinct ocean basins and seas.
• Specific instrumentation is documented: Carbon dioxide (CO2) gas analyzer and shower head chamber equilibrator.

Limitations

• Key metadata such as row count, file size, and specific column names are not provided by any source.
• Conflicting 'last updated' dates exist between platforms (2018-10-18 vs. 2026-03-06), creating uncertainty about metadata freshness.
• The dataset's license and specific data author are unknown.
