The Global Lake Environmental Observatory Network (GLEON) and the Coral Reef Environmental Observatory Networks (CREON) were formed in March 2005 during a workshop held in San Diego, CA. The third GLEON/CREON Workshop was held at the National Center for High-Performance Computing's (NCHC) Hsinchu Taiwan headquarters from Sept. 29th through Oct. 4th. After three days of observation in the great outdoors and two days of workshop, the third GLEON/CREON Workshop successfully concluded on 10/04. The meeting topics included GLEON/CREON's development planning over the next two years. In particular, the workshop focused on how to combine lake and coral observation points, coming up with standards for records keeping, developing a standard user interface, and on obtaining basic equipment and service modules. Also there was discussion on how best to promote GLEON/CREON's results to the community. The GLEON/CREON projects serve to bring together lake and coral reef ecologists and biologists, computer scientists, and sensor network IT engineers and experts to help exploit new opportunities cyber infrastructure has to offer. The goal of the GLEON/CREON workshops is to build capacity and link the infrastructure of all involved communities. GLEON/CREON's member institutes include the NCHC, San Diego Supercomputing Center (SDSC), Australia's Australian Institute of Marine Science (AIMS), the world bank coral reefs projects, the National Oceanic & Atmospheric Administration (NOAA), and Academia Senica's Diverse Biological Research Center, the Executive Yuan's Department of Forestry Experimentation, the International Long Term Ecological Research Network (ILTER), the University of Wisconsin, USA, and the University of Canada. Twenty different research agencies represent eight different countries including Australia, USA, New Zealand, Japan, and Korea came to participate in the workshop. For the third GLEON/CREON Workshop, the NCHC arranged local outings to two prominently long-term observation spots. Visitors were able to share in the NCHC's experience setting up observation networks at Yu Yong Lake (YYL) and the Kenting National Park coral reef observation point. The Chairman of PRAGMA, Peter Arzberger, praised these two opportunities because the workshop let the members observe how the network monitoring grid was set up. It also opened up the discussion and brought about a sense of camaraderie among attending participants. The NCHC has been working hard to promote the lake observation network. After receiving much positive response from NCHC's YYL and University of Wisconsin's Trout Lake observation project, the NCHC has been busy promoting the global observation network. The YYL observation network was asked to join GLEON and the NCHC has become one of GLEON's four advisors as well. In this meeting, we also discussed the new observation lakes in Australia, Finland, New Zealand, China, Israel, England, and Korea. On the CREON side, the following organizations made their presentations: Australia's AIMS, US's LTER, and Santa Barbara's Moray Island. CREON participants also discussed data formats, upload methods, and application promotion. Dr. Tung Yung Fan from the National Museum of Marine Biology and Aquarium shared his coral reef records on the effects that different levels of light and temperature have on the reef's reproduction and growth. Dr. Fang Pang Lin said that the fiber optic network that the NCHC pROVides to the Oceanic Institute is being well used, and the NCHC would be happy to pROVide computational and Grid services to the project as well. Another common problem discussed was how to pROVide and build research platforms for discussion among the different groups in order to prevent making duplicate mistakes. Also discussed was how everyone should follow the same variable measurement standards and how GLEON/CREON can form a positive collaborative atmosphere. Finally, participants in the third GLEON/CREON Workshop invited each other to the 4th meeting to be held in Finland.
