Ocean Carbon Dioxide Measurements from Ship Cruises, 1977-1990

Surface underway measurements of carbon dioxide partial pressure and other variables collected from multiple research vessels across global oceans from 1977-11-07 to 1990-04-16. The data include barometric pressure, sea surface temperature, and nitrous oxide, collected using carbon dioxide gas analyzers and equilibrators. These data were collected by Ray F. Weiss of the University of California - San Diego; Scripps Institution of Oceanography across numerous cruise legs.

Use Cases

• Analyze historical trends in ocean carbon dioxide partial pressure based on the time-series measurements.
• Model ocean-atmosphere carbon flux based on concurrent measurements of atmospheric and aquatic carbon dioxide.
• Study regional variability in marine chemistry based on data from diverse global locations like the Alboran Sea and Arabian Sea.
• Correlate sea surface temperature with carbon dioxide levels based on the included physical variables.

Strengths

• Data spans over 12 years from 1977 to 1990, providing a multi-decade time series.
• Covers a wide geographic range including the Alboran Sea, Arabian Sea, Caribbean Sea, and others.
• Includes multiple related variables: carbon dioxide partial pressure in air and water, barometric pressure, sea surface temperature, and nitrous oxide.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 1990-04-16 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
