Global oceans surface underway data includes measurements of partial pressure of carbon dioxide, salinity, sea surface temperature, barometric pressure, and water temperature. Data was collected from October 1957 to March 2013 by researchers from the Carbon Dioxide Information Analysis Center and Columbia University's Lamont-Doherty Earth Observatory. This dataset constitutes the LDEO Database Version 2012.
Use Cases
- Modeling ocean-atmosphere CO2 flux using partial pressure of carbon dioxide and sea surface temperature measurements.
- Analyzing long-term trends in marine carbon chemistry by correlating partial pressure of carbon dioxide data with salinity and water temperature over the 56-year period.
- Calibrating carbon cycle models with in-situ barometric pressure and sea surface temperature data from global underway measurements.
- Studying spatial variability in ocean carbon uptake by mapping partial pressure of carbon dioxide against concurrent salinity readings.
Strengths
- Temporal coverage spans over 56 years from 1957 to 2013.
- Includes direct measurements of key variables like partial pressure of CO2, salinity, and sea surface temperature.
Limitations
- Specific row count, column details, and sample size are unknown.
- Data collection ended in 2013, limiting analysis of recent ocean carbon trends.
