These pages present a collection of recent papers primarily documenting the nascent science of neutrino geophysics. Most of the papers followed from talks given at Neutrino Sciences 2005: Neutrino Geophysics held at the University of Hawaii in December 2005. Several papers were solicited later in an effort to make the collection as comprehensive as possible. Every paper was scrutinized by an external reviewer to assure the quality of scientific content.

Stephen T. Dye is an associate professor of physics at Hawaii Pacific University and an affiliate to the graduate faculty of the Department of Physics and Astronomy at the University of Hawaii at Manoa.
