1968-11-16 to 2013-12-31 of surface underway observations for carbon dioxide partial pressure, salinity, and sea surface temperature across the world's oceans. The dataset was collected by researchers from the Carbon Dioxide Information Analysis Center, NOAA PMEL, and University of Bergen as part of the SOCAT Database V3. It includes chemical, meteorological, navigational, and physical variables measured using instruments like CO2 gas analyzers.
Use Cases
- Analyzing trends in Partial pressure (or fugacity) of carbon dioxide - water over time using the 45-year time range and LATITUDE/LONGITUDE coordinates.
- Modeling the relationship between SEA SURFACE TEMPERATURE, SALINITY, and surface ocean CO2 concentrations for carbon cycle studies.
- Investigating regional variability in ocean carbon sinks by aggregating data by LATITUDE and LONGITUDE bins.
- Correlating BAROMETRIC PRESSURE measurements with surface CO2 readings to study gas exchange processes.
Strengths
- Temporal coverage spans 45 years from 1968 to 2013.
- Global spatial coverage across the world-wide oceans.
- Includes multiple directly measured variables (CO2, temperature, salinity, pressure) per observation.
Limitations
- Specific row count, sample size, and data density are unknown.
- Data collection platforms are listed as 'unknown platforms', limiting provenance tracing.
- Data is temporally stale, with the last update in 2013.
