John Delaney is an oceanographer who studies the behavior of deep-sea volcanoes along the Juan de Fuca Ridge in the Pacific Ocean, just off the coast of Washington state. As Director of the Neptune Program, he has overseen the development of the regional cabled ocean observatory in the northeast Pacific Ocean as part of the National Science Foundation's Ocean Observatories Initiative—an unprecedented effort that uses fiber-optic cables to effectively bring the Internet into the Pacific Ocean and onto the seafloor, providing high-quality, real-time data to a global audience. In addition to studying the linkages among volcanoes and life here on Earth, he is also interested in the search for life elsewhere in the solar system, and has worked with NASA to plan space missions to the moons of Jupiter. He is a Fellow of the American Geophysical Union. Delaney holds the Jerome M. Paros Endowed Chair in Sensor Networks.
