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.

A tradition of the Global Lake Ecological Observatory Network (GLEON) is for members from around the world to host the annual meeting in their respective country, choosing a venue that is scientifically, culturally and aesthetically important. For the 19th GLEON All Hand’s Meeting in 2017, the local organizing team is ahead of the curve, selecting a wonderful meeting location, the Mohonk Mountain House on the shore of Mohonk Lake in New Paltz, New York. The Mohonk Mountain House is a spectacular venue — imagine Hogwarts, the famous school of Harry Potter stories, meets GLEON. The GLEON 19 meeting will take place from 27 November to 1 December 2017 and is co-hosted by SUNY New Paltz, Mohonk Preserve, and Cary Institute of Ecosystem Studies. The registration deadline was extended today to Friday, 15 September 2017.
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…)
A new citizen science working group formed in July at the most recent all-hands meeting of the Global Lake Ecological Observatory Network (GLEON) in Gaming and Lunz, Austria. With the official end of the Networking Lake Observatories in Europe (NETLAKE) EU COST Action this year, the working group activities under GLEON’s sister network in Europe found a new home by merging with ongoing initiatives in GLEON. What had been an adhoc group on citizen science in GLEON became a full-fledged working group this summer with several joint projects already underway.
“Experience from GLEON demonstrates how citizens contribute to the formulation of new research questions about their lakes as well as how research scientists are embracing citizen science in the network,” said Kathleen C. Weathers, co-chair of GLEON, and G. Evelyn Hutchinson Chair in Ecology at the Cary Institute of Ecosystem Studies in Millbrook, NY. “With the establishment of a new working group, GLEON members are not only embracing citizen science but actively designing and implementing

GLEON’s 18th All-Hands Meeting and joint meeting with NETLAKE was held from 4-8 July, 2016 in Lunz & Gaming, Austria. There were approximately 140 individuals who attended the meeting; about 60 percent of the participants were faculty, scientists, and/or staff and 40 percent were students and postdoctoral researchers. 33 countries were represented, spanning 85 institutions. The meeting consisted of a diversity of GLEONites and NETLAKE’ers, and for 40 percent of the participants, this was their first All-Hands meeting. (more…)
Currently, I am a Ph.D. Candidate in the Department of Biological Sciences and a fellow in the Interfaces of Global Change at Virginia Tech. Dr. Cayelan Carey, a long-term GLEONite, is my advisor, and she first introduced me to GLEON a few years ago. For my Ph.D. research, I combine field and laboratory research with ecosystem modeling to quantify how multiple environmental and human factors interact to affect plankton ecology and water quality in lakes and reservoirs. Prior to my time at Virginia Tech, I earned my B.S. and M.S. from the University of Michigan in environmental science where my research focused on planktonic food webs in the Great Lakes. (more…)

A lake is like a gigantic living creature that inhales and exhales carbon and exchanges energy with its surrounding environment. I became interested in this process and wanted to understand and predict whole-lake carbon exchange systems in Brazilian lakes. I worked on this topic for my Ph.D. (which I completed recently!), and deployed a high-frequency monitoring buoy to obtain data. This led to a new collaboration between researchers in Brazil and Denmark: Carbon Cycling on Lakes (COCLAKE), looking at the similarities and differences of temporal and tropical lake carbon cycling systems. All of this started from a simple conversation at a GLEON meeting. With the GLEON 16 meeting fast approaching, I wanted to share my story for those who are attending.
It was a sunny November afternoon at La Salada, a shallow lake, when we said our goodbyes to the GLEON 15 meeting participants. From the 4th of November to the 8th, 2014, the meeting was held mainly in the city of Bahía Blanca, Argentina.
It was an extremely fun, productive and successful meeting of the minds and of old and new friends. On Monday, the pre-meeting GSA Workshop started the week-long meeting, where researchers and postdocs joined 56 students from diverse countries such as China, Brazil, Ireland, New Zealand, Canada and USA, as well as Argentina.
