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

该奖项是对美国国家科学基金会赠款0001827的基于成就的续展，该赠款支持在库克7号探险队(R/V梅尔维尔)期间对马里亚纳岛南部弧区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。这项奖励将允许在未来五年内开展以下4项研究工作：1)根据库克行动期间收集的样本完成4个子项目。2)参加美国国家海洋和大气局的邮轮，与水下机器人一起研究马里亚纳群岛的热液遗址。PI已被邀请参加并研究在计划中的巡航中收集的火成岩。3)参加JAMSTEC对博宁群岛以西的婴幼儿弧壳的研究。一个由美国和日本科学家组成的团队提议使用JAMSTEC的Shinkai 6500载人潜水器来研究日本博宁群岛以西陡坡上暴露的婴儿弧形地壳。潜水计划承诺解决蛇绿岩难题，并帮助演示俯冲带是如何开始的；以及4)继续参与边缘地区对2003年5月阿纳塔罕喷发的快速反应。

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.
