Mantle Inputs to the Subduction Factory: Assessing Scales of Spatial Variability along and across the IBM Convergent Margin

该奖项是美国国家科学基金会0001827基金的成果更新，该基金支持在库克7号探险（R/V Melville）期间对南马里亚纳弧和弧后盆地进行测量和采样，作为边缘俯冲工厂实验的一部分。该奖项将允许在未来五年内开展以下4项研究工作：1)完成在Cook 7期间收集的样品上开始的4个子项目。2)参加NOAA巡航，利用ROV研究马里亚纳群岛的热液地点。PI已被邀请参加并研究计划巡航期间收集的火成岩。3)参与JAMSTEC对博宁群岛西部幼弧壳的研究。一个由美国和日本科学家组成的团队提议使用日本海洋科学研究中心的“新海6500”载人潜水器，研究暴露在日本小笠原群岛以西陡坡上的幼年弧壳。这个潜水项目承诺解决蛇绿岩之谜，并帮助展示俯冲带是如何开始的；4)继续参与2003年5月安纳塔汉火山爆发的边缘快速反应。

This award is an Accomplishment-Based Renewal of NSF grant 0001827, which supported surveying and sampling of the southern Mariana arc and back-arc basin during the Cook 7 expedition (R/V Melville) as part of the MARGINS Subduction Factory experiment. This award will allow the following 4 research efforts over the next five years: 1) Completion of four sub-projects begun on samples collected during Cook 7. 2) Participation in a NOAA cruise to study hydrothermal sites in the Marianas with ROV. The PI has been invited to participate and to study igneous rocks collected during the planned cruise. 3) Participation in JAMSTEC study of infant arc crust west of the Bonin Islands. A team of US and Japanese scientists propose to use JAMSTEC's Shinkai 6500 manned submersible to study exposures of infant arc crust exposed along scarps west of the Bonin islands, Japan. The diving program that promises to resolve the ophiolite conundrum as well as help demonstrate how subduction zones begin; and 4) Continued Participation in MARGINS Rapid Response to May 2003 Eruption of Anatahan.
