Researchers investigated methane emissions in Lake Abashiri to understand its impact on climate change. They focused on how methane moves in the lake and identified key factors contributing to its release: methane coming from the lake's bottom layer, aerobic microbes decomposing methane, and anaerobic environments also breaking down methane. By creating a model using 3D numerical simulations, they found that these processes play significant roles in methane emissions from lakes. This study helps us better understand how methane, a potent greenhouse gas, is released into the environment from lakes, contributing to climate change.
