Under this award, the PI will convene the third in a series of State of the Arc (SOTA) conferences aimed at understanding physical-chemical processes operating at subduction zones. The conference will have as its theme, Energy and Mass Fluxes in Volcanic Arcs. The meeting will be held in August 2003 at Timberline Lodge (Mt. Hood). Rice University will act as the lead institution, and the conference will be hosted locally by Portland State University. The meeting will bring together approximately 84 international researchers whose work bears on the conference theme. Specific focus areas will include: (1) the thermal structure of subduction zones, (2) the influence of this structure on release of volatiles and possibly melts from subducted slabs, (3) influence of this structure on the production and differentiation of magmas at various levels in the mantle and crust, (4) geologic, petrologic, geochemical, and geophysical constraints on the reservoirs that store and release those magmas and their associated fluids, and (5) heat and mass transfer processes and rates in arc volcanoes at different spatial and temporal scales, and how these influence volcano evolution and behavior. The conference will include a series of pre-, mid-, and post-conference field trips to view important aspects of arc volcanism as exposed in the Cascades province (Mt. St. Helens, Mt. Hood, and central Oregon). These trips will integrate aspects of field geology with the conference themes and allow contrast between different styles of arc volcanism.

根据该奖项，PI将在旨在理解俯冲区域运作的物理化学过程的一系列弧（SOTA）会议中召集第三个。该会议的主题，能源和大规模通量将在火山弧中。会议将于2003年8月在Hood Lodge（Hood）举行。赖斯大学将担任主要机构，该会议将由波特兰州立大学本地主持。这次会议将汇集大约84位国际研究人员，他们的工作对会议主题的支持。特定的重点区域将包括：（1）俯冲带的热结构，（2）这种结构对挥发物的释放的影响，并可能从俯冲板上融化，（3）这种结构的影响对岩浆的生产和分化对岩浆的生产和分化，在地幔和地壳中的各个层次，（4）地理，地球，地球，地球，地球，地球，地球，地球，地球，地球，地球和地球群体，并将其重新分配。相关的流体以及（5）在不同的空间和时间尺度上的弧火山中的热量和传质过程以及速率，以及这些如何影响火山的演化和行为。该会议将包括一系列会议前，中和会议后的野外旅行，以查看喀斯喀特省（St. St. Helens，Hood，Hood和Central Oregon）暴露的电弧火山主义的重要方面。这些旅行将将现场地质的各个方面与会议主题相结合，并允许不同风格的弧形火山主义之间进行对比。
