NCEI 0157394: Ocean Carbon Fugacity from Surface Underway Cruises

Surface underway measurements of carbon dioxide fugacity, salinity, sea surface temperature, and barometric pressure were collected from five research vessels across the Pacific and Indian Oceans from 1981 to 1989. The data were gathered using a Carbon dioxide (CO2) gas analyzer during 17 distinct research cruises led by the Meteorological Research Institute. This dataset provides a multi-year record of oceanic and atmospheric carbon dioxide partial pressures for studying ocean-atmosphere gas exchange.

Use Cases

• Calculating air-sea CO2 flux gradients based on simultaneous atmospheric and water partial pressure measurements.
• Analyzing decadal trends in sea surface temperature and salinity alongside carbon system parameters.
• Validating regional ocean carbon cycle models for the North Pacific, South Pacific, and Arabian Sea.
• Studying the spatial distribution of carbon dioxide fugacity across major ocean basins from ship transects.

Strengths

• Covers a multi-year time range from 1981-01-20 to 1989-02-11.
• Includes data from 17 distinct research cruises across multiple ocean basins.
• Provides simultaneous measurements of atmospheric and aquatic carbon dioxide partial pressure.

Limitations

• Key metadata such as row count, file size, and specific column names are unavailable across all sources.
• Conflicting 'last updated' timestamps (1989-02-11 vs. 2026-03-06) suggest unclear metadata maintenance.
• The dataset's license and detailed instrument specifications are not provided.
