The U.S. Environmental Protection Agency (EPA) released the 2012 National Lakes Assessment (NLA) data in December, which are now publicly available online.
Every five years, the EPA launches a comprehensive sampling campaign, where together with state and local governments, tribes, and many other agencies, they sample over 1000 lakes and reservoirs (hereafter, together referred to as waterbodies) across the United States. The final set of waterbodies that are sampled are selected randomly using a statistical survey design to appropriately sample waterbodies that are representative of the U.S. waterbody population across multiple size classes. The first comprehensive survey conducted by the EPA was in 2007, and so this represents the second survey. Approximately 400 waterbodies were resampled in 2012, and approximately 600 were newly sampled waterbodies.
For each sampled waterbody, there are a diverse suite of variables collected and analyzed such as: waterbody morphometric characteristics, lakeshore land use, profiles of e.g. temperature and dissolved oxygen, many water chemistry variables, and phytoplankton and zooplankton metrics such as density and biomass at the genus resolution. Field crews follow standardized protocols at each waterbody, and water samples for water chemistry and plankton counts are analyzed at central laboratories, subjected to multiple phases of quality control.

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…)

The 2nd Annual NE GLEON conference held at the Cary Institute of Ecosystem Studies in Millbrook, NY, from April 15-17, gave students and professors representing 11 universities and colleges in northeastern North America the opportunity to experience a “mini” version of a GLEON all-hands meeting. Although undergraduates were the focus of the weekend meeting, comprising nearly half of the 32 participants, graduate students and faculty members also gathered to share data and plan regional research activities for the coming year.
“I had the amazing opportunity to attend the regional NE GLEON conference. There were several students from various institutions with a wide array of majors, backgrounds, and interests. Although this was my second time attending a NE GLEON meeting, I was still greeted with enthusiasm, almost like being reunited with old friends,” said Brian Kim, an undergraduate student from Colby College in Maine.

I gratefully accepted a recent appointment as co-chair elect of the Global Lake Ecological Observatory Network (GLEON) Graduate Student Association (GSA), the newest member of the GSA leadership team, joining GSA chair, Jennie Brentrup (Miami University, USA) and co-chair Facundo Scordo (Universidad Nacional del Sur, Argentina). One of my first assignments is to briefly introduce myself to the GLEON community. (more…)

It was a dark and stormy night. Well not exactly stormy, but it had been dark since 5 pm and was exceptionally cold (mostly for those joining the group from warmer areas of the world); nothing but a typical January evening in central New Hampshire. It was the night following the fourth and final day of the Global Lake Ecological Observatory Network (GLEON) Fellowship Program workshop at Lake Sunapee, New Hampshire, a quaint lake side community largely dormant for the winter.

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.

It is with joy that the GLEON Collaborative Climate Committee (CCC) and Graduate Student Association (GSA) welcome Paula Zapperi and Thomas Harmon as new members of the CCC, and Liz Ryder as the new co-chair of the CCC. They were elected to be the member of the committee in February 2014, and we are excited to see the new enthusiasm and contributions they have to offer.
The GLEON Student Association (GSA) welcomes Facundo Scordo as the new co-chair elect. He has a background in Environmental Sciences and is currently enrolled as a Ph.D. candidate in the Geography department at the Universidad Nacional del Sur in Argentina. Facundo was elected to the new leadership role in February 2014 and is expected to take the co-chair position, after the G16 meeting in 2014, and the chair position, after the G17 meeting in 2015. Congratulations, Facundo!
