Description:

Greenhouse gases and small streams. In order to find whether streams might be the important producers of greenhouse gases into the atmosphere, we focused to determine total emissions of CH4, CO2 and N2O from a surface water of the small lowland stream to the atmosphere. We found that vast majority of annual methane emissions (90 %) is produced in lower, 7 km long stretch of the stream which represents only 1/5 of the total calculated area of the stream. Emission of the methane to the atmosphere are greatest during the spring and summer period when the water temperature is elevated. Totaly, 211 t of greenhouse gases were annually emitted to atmosphere from the water level (-0,2 km2) with a dominant proportion being CO2.
