U04 The Deep Earth Engine: Geophysics and Geochemistry
The present-day state and dynamics of the Earth's deep interior provide the key to understanding the forces driving geology, and reveal the connections between the surface environment and the interior. A full characterization of the deep Earth engine is thus a prerequisite for our ultimate goal of understanding Earth circulation as a whole. This understanding can emerge from focused efforts including studies of the pattern of large-scale flow in the mantle, the composition and structure of the mantle, and the operation of the geodynamo, and from interdisciplinary studies that integrate observations and models from a variety of sources. This interdisciplinary session will bring together seismologists, geodynamicists, geomagnetists, mineral physicists, petrologists, and geochemists to explore global and regional aspects of the internal structure of the Earth's interior. A variety of international efforts and programs have emerged in the past decade to promote deep earth research; this session will highlight the successes of these efforts and the future challenges involved in understanding the deep earth engine.

SF13 Cyberinfrastructure in Geochemistry
Geochemistry has broad significance across the planetary sciences. However, such breadth requires a coherent and unifying set of concepts and principles to organize and present empirical data in a way that it can be used effectively by the broader geoscience community. A clear scientific vision, combined with a flexible information technology (IT) structure, will accelerate the rate of discovery and expand the breadth of impact of geochemical results in other disciplines. This session will focus on demonstrations of the utility and capabilities of existing and developing geochemical cyberinfrastructure efforts. Specifically, the session will address such issues as:
• Science advances fostered by modern computation and visualization techniques for large datasets • Expansion of existing datasets to better serve the needs of the geoscience community • Identification of practical solutions and approaches that will help overcome the obstacles related to the interoperability of various existing and new databases within geochemistry and related fields, such as geochronology, paleomagnetics and the biogeosciences • Proposed scientific data models to capture, archive and present the wide variety of geochemical data • Development of innovative and user-friendly data population mechanisms • Definition of standardized data collections and models for possible geochemical data federations • Community approaches to metadata and data interoperability protocols, standards and interfaces that will enable more effective and enduring data integration within geochemistry, as well as between geochemistry and other disciplines.
