NOAA NCEI Accession 0208893 contains surface underway chemical, meteorological, and physical time series data from the POSEIDON E1-M3A buoy in the Cretan Sea. Measurements include partial pressure of carbon dioxide (pCO2), sea surface salinity, sea surface temperature, and barometric pressure, collected from June to December 2018. The data were gathered by the NOAA National Centers for Environmental Information using instruments including a CO2 gas analyzer and non-dispersive infrared detector.
Use Cases
- Analyze temporal trends in pCO2 to study seasonal carbon cycling in the Eastern Mediterranean coastal zone.
- Correlate sea surface temperature and salinity measurements with pCO2 levels to understand driving environmental factors.
- Use barometric pressure data alongside pCO2 to calculate air-sea CO2 flux estimates.
- Model short-term (6-month) variability in coastal ocean carbon chemistry from high-frequency buoy observations.
Strengths
- Data provides a continuous 6-month time series from a fixed coastal buoy location.
- Includes key variables for carbon flux calculation: pCO2, temperature, salinity, and barometric pressure.
Limitations
- Dataset covers only a single 6-month period, limiting analysis of interannual variability.
- Spatial coverage is limited to a single buoy location in the Cretan Sea.
