Stream and River Methane Emissions
Abstract
Over the last few years, increasing attention is being paid to the degassing of methane from inland waters. Although the knowledge base of the magnitude and controls of methane efflux is growing, a large amount of uncertainty remains. This presentation will discuss this knowledge base and present a new estimate of methane emissions from streams and rivers using the latest set of direct methane measurements estimations of streams surface area and turbulence. Regional estimates will be compared to CO2 and N2O degassing in order to begin to get a holistic understanding of greenhouse gas emissions from flowing waters
