Methane in the Danube Delta: the importance of spatial patterns and diel cycles for atmospheric emission estimates

Anna Canning, Bernhard Wehrli, and Arne Körtzinger

Data sets

Seasonal high-resolution sensor data for pCO2, pCH4, O2 and temperature/salinity within the Danube Delt A. Canning and M.-S. Maier

Short summary
Inland waters are usually not well restrained in terms of greenhouse gas measurements. One of these regions is the Danube Delta, Romania. Therefore, we measured continuously with sensors to collect high-resolution data for CH4 and O2 throughout the Delta. We found significant variation for all concentrations over the day and night and between regions, as well as large spatial variation throughout all regions, with large CH4 concentrations flowing in from the reed beds to the lakes.
