Surface Ocean Carbon Dioxide Measurements from 1957 to 1963
Description
Surface underway data collected from unknown platforms across the Andaman Sea, Arabian Sea, Caribbean Sea, and other ocean regions from 1957-10-21 to 1963-08-15. These data include AIR-SEA DIFFERENCE - PARTIAL PRESSURE (OR FUGACITY) OF CARBON DIOXIDE, BAROMETRIC PRESSURE, Partial pressure (or fugacity) of carbon dioxide - atmosphere, Partial pressure (or fugacity) of carbon dioxide - water and SEA SURFACE TEMPERATURE. The data were collected by Charles D. Keeling of Scripps Institution of Oceanography as part of the Keeling_1957_1963 dataset.
Use Cases
Analyzing historical trends in oceanic carbon dioxide partial pressure based on surface underway measurements.
Modeling air-sea carbon dioxide flux based on the difference between atmospheric and water partial pressure.
Correlating sea surface temperature with carbon dioxide concentrations across multiple ocean basins.
Studying early instrumental records of carbon dioxide as part of the Keeling time series legacy.
Strengths
Data spans nearly six years from 1957 to 1963, providing a historical baseline.
Covers a wide geographic area including the Andaman Sea, Arabian Sea, Caribbean Sea, Indian Ocean, and others.
Includes key variables for carbon cycle research: partial pressure of CO2 in air and water, sea surface temperature, and barometric pressure.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Last updated 1963-08-15; freshness should be verified for modern applications.
The specific platforms used for data collection are listed as 'unknown', limiting provenance assessment.
