My EGU25 highlights: Inspiring inland water greenhouse gas emission science

Teresa Silverthorn and Lucia Layritz July 21, 2025

field measurements of greenhouse gas emissions using floating chambers on a agricultural drainage ditch.

The notion that inland waters are passive participants in biogeochemical cycling, with lakes as recipients and rivers as pipes, has long been overturned. More and more research suggests the global importance of inland waters in biogeochemical cycles, particularly in greenhouse gas (GHG) exchange. EGU25 had a remarkable line-up of talks and posters on inland water GHG emissions. I’ll revisit some o ...[Read More]
