The 2013 Gordon Conference on the Earth's Deep Interior will push the leading edge of research on the structure, dynamics and evolution of the deep Earth and planetary interiors. The Conference will address a wide range of topics from a multi-disciplinary perspective. Invited speakers from the fields of geochemistry, geodynamics, geomagnetism, mineral physics and seismology will define the forefront of knowledge and set the stage for a freewheeling discussion and debate of the most pressing scientific questions. Specific session topics include inner core structure and dynamics, the structure and nature of LLSVP's (large low shear velocity provinces), the mantle transition zone and interactions between the upper and the lower mantle, early earth and geochemical reservoirs, rheology and mineralogy of the deep mantle, the core-mantle boundary and core/mantle interactions, planetary interiors. The conference will also provide the opportunity for junior scientists and graduate students to present their work in poster format and exchange ideas with leading researchers. The collegial atmosphere, with programmed discussion sessions and opportunities for informal gatherings, is intended to generate lively exchange and promote cross-disciplinary collaborations. The 2013 Interior of the Earth Gordon Conference will be preceded by a Gordon Research Seminar aimed at graduate students, postdocs and very junior scientists. Gordon meetings are special in that they are intimate yet broad in their objectives. We expect an attendance of ~150 for the GRC, and 50-70 for the GRS. Most of the GRS participants are expected to stay for the GRC. Oral contributions are by invitation-only, but there will be vibrant poster sessions in both GRS and GRC, as well as time every afternoon for free interactions between participants young and older. A great oppotunity to start cross-disciplinary collaboration and learn about the most recent findings in neighboring fields. Partial support for graduate students and post-docs may be available.
