Project to Advance Understanding of Carbon Dioxide Emissions from Lakes

DC Flux Logo

By Blaize Denfeld

During the GLEON 18 meeting last summer, the lake metabolism working group started the week by discussing the current state of knowledge of greenhouse gas (GHG) emissions from inland waters – it is evident that inland waters play an important role in the global carbon cycle, emitting both carbon dioxide (CO2) and methane (CH4) into the atmosphere. As new scientific research is published and advancements in technology are made, as scientists, we can fill gaps and improve our scientific understanding. One such gap identified by the lake metabolism working group was the potential sampling bias in greenhouse gas emission estimates from lakes, since most estimates are made during the day. Inspired by the current EuroRun project— a Collaborative European Freshwater Science Project for Young Researchers that focuses on estimating CO2 fluxes from European running waters— and thanks to relatively inexpensive technological advancements in GHG emission measurements, the DC Flux (diurnal CO2 flux variation across latitudinal gradients) project was born.
