CIDER (Cooperative Institute for Deep Earth Research) is an emerging initiative within the solid Earth community in the US, designed to remedy the lack of satisfactory communication and cooperation among the geoscience fields dealing with the Earth's deep interior, defined here as anything between the crust and the Earth's center. It has been 35 years since the acceptance of plate tectonics theory, but no definitive agreement has yet been reached among geoscientists on the fundamental nature of the global dynamic processes that drive plate motions. There are still vigorous debates about the proportion of heat coming from the core, vs. radiogenic heating in the mantle, about the degree to which the 670 km discontinuity impedes whole mantle circulation, about the origin of mantle plumes, or the chemical or thermal nature of heterogeneity in the deepest mantle. The principal mission of Cider is to provide a long-range intellectual framework that will allow a more effective cross-fertilization of the different disciplines, whereby senior and junior scientists alike can be thoroughly educated about the approaches, the fundamental achievements, the future potential and limitations of the "other disciplines", in order to gain a common language. Given the enormous amount and diversity of observations becoming available across the relevant disciplines, a quantum leap in the understanding of our planet's interior - the constitution and evolution of the Earth - is about to take place if we can better understand the key issues and how to address them by fully utilizing complementary disciplinary data and modeling tools. This will be accomplished through a series of short and long courses, workshops, and interdisciplinary research programs focused on a specific topic. A related goal is to attract to geophysics more talented and better prepared graduate students.
