Surface underway measurements of carbon dioxide partial pressure, salinity, sea surface temperature, and barometric pressure collected from ships across the world-wide oceans. The dataset was compiled by researchers from the Pacific Marine Environmental Laboratory, Universite Pierre et Marie Curie, University of Bergen, and University of East Anglia as part of the SOCAT Database V1.5. Observations span from November 16, 1968, to December 31, 2007.
Use Cases
- Modeling ocean-atmosphere CO2 flux using partial pressure (or fugacity) of carbon dioxide - water and sea surface temperature fields.
- Analyzing long-term trends in surface ocean carbon chemistry by joining partial pressure of carbon dioxide with salinity and temperature time-series.
- Calibrating satellite-derived sea surface temperature products with in-situ sea surface temperature measurements from this dataset.
- Studying correlations between barometric pressure and oceanic carbon dioxide partial pressure under varying meteorological conditions.
Strengths
- Temporal coverage spans 39 years from 1968 to 2007.
- Includes multiple concurrent variables: carbon dioxide partial pressure, salinity, temperature, and barometric pressure.
- Data is part of the curated SOCAT (Surface Ocean CO2 Atlas) Database V1.5.
Limitations
- Specific row count, column details, and sample size are unknown.
- Platform information is listed as 'unknown platforms', limiting metadata for source attribution.
- Data is temporally stale, with the last update recorded in 2007.
