The 2015 Gordon Conference on the Interior of the Earth has a theme of "Surface Connections" and will feature new research on the structure and dynamics of Earth’s interior and their influence on surface processes ranging from tectonics to volcanism to climate. The conference will address these topics from a multi-disciplinary perspective. Invited speakers will present current findings from geochemistry, geodynamics, petrology, seismology, volcanology, sedimentology, and planetary sciences. These presentations 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 the dynamics of passive margins, connections between mantle processes and volcanism, deep earth volatile cycles, subduction dynamics, the origin of plate tectonics, the origin of shallow mantle seismic discontinuities, microscopic to macroscopic connections between rock rheology and large-scale tectonics, and the structure and evolution of the continental lithosphere. 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 2015 Interior of the Earth Gordon Conference will be preceded by a Gordon Research Seminar (GRS) 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 opportunity 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.
