  2. Collaboration in Environmental ScienceGlobal Lake Ecological Observatory Network • A grassroots network of • People: lake scientists, engineers, information technology experts • Institutions: universities, national laboratories, agencies • Programs: PRAGMA, AS-Forest Biogeochemistry,US-LTER, TERN, KING, EcoGrid, etc. • Instruments • Data • Linked by a common purpose and cyberinfrastructure • With a goal of understanding lake dynamics at local, regional, continental, and global scales

  3. 3 Networks People Data Lake observatories Source: Paul Hanson

  4. 19 countries participating • More than 120 scientists • Most sites are developing Source: Paul Hanson

  5. GLEON’s Mission Facilitate interaction and build collaborations among an international, multidisciplinary community of researchers focused on understanding, predicting, and communicating the impact of natural and anthropogenic influences on lake ecosystems by developing, deploying, and using networks of emerging observational system technologies and associated cyberinfrastructure. http://gleon.org Source: Tim Kratz

  6. Some current issues in limnology amenable to “observatory” approach • Source, movement, and fate of carbon in lakes and watersheds • Pelagic/littoral coupling • Role of episodic events, thresholds, and non-linear dynamics • Coupling of physical and biological processes Source: Tim Kratz

  7. GLEON Activities • Share experience, expertise, and data • Catalyze joint projects • Develop tools • Conduct multi-site training • Create opportunities for students • Meet and communicate regularly

  8. Science depends on inextricable link among questions, models, and observations Observations Questions sensor networks Models Observations Existing Sensor Networks 100 km 10 km Spatial extent 1 km 100 m 10 m random selection from Ecology 2003 1 m 10 cm Annual Monthly Weekly Daily Hourly Min.

  9. Lake Erken: Deployment Visit 25 – 29 June 2007 GOALS • Install DataTurbine and database system • Gather unique requirements and document process to inform and improve future deployments and developments • Train local staff • Understand challenges at site level where IT level typical of most sites

  10. Lake Sunapee, NH – a recent addition • Collaboration – scientists, educators, • lake association • Motivated by diverse interests • Supported by diverse funding Lake Sunapee Photo: Midge Eliassen Source: Paul Hanson

  11. Creating a Persistent Infrastructure to Enable Network Science • Harden Current Prototypes • Leverage NSF DataTurbine • Improve Deployment, Use • Document Process • Enable Scaling • Conduct Science • Provide Training • Continue to Build Community with NSF GLEON RCN

  12. GLEON and the ISSE Model Integrated Science for Society and the Environment New policies on land use around lake/reservoir Yuan Yang Lake, Taiwan Citizens react when quality degrades Recreation, Property Value Drinking Water Soyang(소 양) Korea Mendota, Madison, Wisconsin

  13. A grassroots approach to sensorand science networks • “The international, grassroots model offers a unique approach for confronting the challenges of doing networked science across large geographic extents.” • “Science is about people …” • Attributes the lead to success: • Community-based science agenda: creates buy-in • Shared data, expertise, and solutions: develops community trust • Representative and open governance structure: empowers individuals, rewards initiative and flexibility • International focus: provides global perspective. • “Ecology is venturing into the realm of big science, … let’s remember that the ecological community consists of many individuals willing and eager to contribute … ” Source: PC Hanson, Frontiers in Ecology and the Environment, Sept 2007, p343
