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.

Lake Annie’s Song: A TEDx Talk and Interview with GLEON’s Evelyn Gaiser

A recent TEDxFIU event kicked off with Global Lake Ecology Observatory Network (GLEON) member Evelyn Gaiser’s unexpected discovery that her two passions, science and music, could come together to help her better understand data. Evelyn’s interpretation of the year-round daily temperature changes in Florida’s Lake Annie formed the basis for her TEDx talk.

Evelyn is a classically trained musician, so when she visualized the temperature data collected from Lake Annie she also saw a musical score. By assigning the data points a musical note, she composed Lake Annie’s song. The piece was then arranged by Marcus Norris and performed by Yaniv Cohen, Aryam Gonzalez and Tomas Lopez, all members of the School of Music on the TEDxFIU stage.

“Music seems uniquely suited to expressing the nuances of nature,” Gaiser said in an FIU News report about the event, noting a growing trend of scientists and musicians around the world coming together to explore the complexities of nature in this way. (more…)
