Digital Moorea is a collaborative vision of a coral reef ecosystem instrumented with real-time sensors connected to high-performance backend resources and sophisticated client applications. It will be a living laboratory for long-term studies of marine ecology and a testbed for evolving technologies for environmental and biological sensing, communications, and analysis. A diverse team of ecologists, computer scientists, and engineers from the Marine Science Institute at the University of California Santa Barbara (MSI, ww.msi.ucsb.edu/)and the California Institute of Telecommunications and Information Technology (CalIT2, www.calit2.net/) are collaborating to bring this vision to reality at the Moorea Coral Reef site(MCR LTER, www.mcr.lternet.edu) of the U.S. National Science Foundation’s Long Term Ecological Research (LTER) program.
