Ecuador Volcanoes Expedition, 2010

Welcome to the website for our Ecuador Volcano Expedition, 2010! Thanks to the National Science Foundation (NSF) and the Office of Interanational Science and Engineering (OISE) for funding our expedition of discovery. Our team consists of scientists and students from California State University Los Angeles, the University of Wyoming, the University of South Carlolina and the Instituto de Geofisico in Quito Ecuador,teaming up with classrooms in the U.S.A and Ecuador to bring science from the field into the classroom.
