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…)

I was recently offered and readily accepted the co-chair elect position of the Global Lake Ecological Observatory Network (GLEON) Graduate Student Association (GSA), joining chair, Blaize Denfeld (Umeå University, Sweden) and co-chair Jonathan Doubek (Virginia Tech, USA). As a new member of the team, I would like to introduce myself and mention in brief my past and present professional and academic involvements. (more…)

Introducing Newly Appointed GSA Leader Jonathan Doubek

Jonathan Doubek recently accepted the position as the next co-chair elect for GLEON’s Graduate Student Association.

Jonathan Doubek enthusiastically accepted the position as the next co-chair elect for GLEON’s Graduate Student Association (GSA), joining GSA chair Facundo Scordo (Universidad Nacional del Sur, Argentina) and co-chair Blaize Denfeld (Uppsala University, Sweden). In this blog post, Jon briefly introduces himself to the GLEON community.

 

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…)

Reflections on GLEON’s 10th Birthday

Ten years ago, a relatively small group of lake scientists, information managers and information technology experts met in San Diego alongside experts on coral reefs in what we now consider to be the first GLEON meeting. G1, though of course none of us called it that – in fact the name GLEON didn’t yet exist – started an adventure in doing network science.

The goal of the first meeting was to explore whether developing an international network that deployed and made use of high-frequency measurements on lakes and coral reefs made sense scientifically, socially, and practically. It resulted in what we now know as the Global Lake Ecological Observatory Network, or GLEON, a thriving, energetic, and creative network that has brought an international community of scientists together. But back then, we had only a dim inkling of what GLEON would become a decade later. (more…)

NETLAKE Summer Training School: A Workshop for Both Early Stage Researchers and Lifelong Learners

By Liz Ryder and Eleanor Jennings

The first NETLAKE (Networking Lake Observatories in Europe, EU COST Action ES1201) training school took place from 12th to 17th June 2014 at the Erken Laboratory, Uppsala University, in Sweden. A multi-disciplinary group of 23 trainees from 19 countries took part. The training focused on automated monitoring and high-frequency data analysis, and included techniques for building simple temperature sensors, deployment, data analysis and processing, data visualization and practical data management.

PRAGMA-GLEON Expedition, 2014

by Meilan Jiang

The Pacific Rim Application and Grid Middleware Assembly (PRAGMA) 26th meeting was held in Taiwan in April with the underlying theme of “Living with Big Data.” Recent efforts of the GLEON – PRAGMA collaborative scientific expedition were shared at a group session in the meeting, and challenges and milestones of this collaboration were identified.

The PRAGMA 27th meeting will be held in October at Indiana University Bloomington just before the GLEON meeting. The new conceptual interdisciplinary challenge, a “Hackathon,” will be operated at PRAGMA 27, and GLEON members are encouraged to participate in this event.

GLEON Buoy Data Used in a Variety of Ways

Recent Bard Center for Environmental Policy (CEP) graduate Alicia Caruso delved deeply into the uses of GLEON data and found that high-frequency buoy data is being shared widely, and a new collaboration with database managers may improve data accessibility to promote greater collaborations with a broader audience of GLEON members and local lake managers. As part of a master’s thesis project, Alicia aimed to answer several questions relating to GLEON and the uses of high-frequency data collected on GLEON buoys worldwide. These include questions on what is currently happening with the data that GLEON is collecting, how it can be used, what benefits and challenges are involved with communicating these data both within the organization and with non-academic users, and how that communication could be improved. Answers to these questions were determined through the use of surveys and interviews.
