Carbon emissions from river networks 

Rivers are tiny vessels in in the landscape, invisible from the sky. But, rivers and streams play a big role shaping the global carbon cycle, receiving large amounts of matter from land and emitting CO2 and CH4 to the atmosphere. Understanding the processes regulating those emissions and how they reflect the landscape they are embedded on, is one of the main research we are pursuing. 
 

Methane, a big threat but also an opportunity 

Methane is a powerful gas of greenhouse effect, trapping far mor heat than CO2. Methane is largely emitted from aquatic environments, because it is produced by anaerobic bacteria in water saturated soils and sediments. In this lab we are working on better understanding how Arctic river ecosystem produce and emit methane to the atmosphere, by combining field observations, whole system experiments, and modelling.
