This project will utilize a scheduled JAMSTEC cruise that includes 10 research dives to the Mariana volcanoes. Two primary objectives of this research cruise are to understand 1) the evolution of the IBM forearc during subduction initiation, and 2) the igneous and hydrothermal activity of the active modern submarine arc. This work will investigate the submarine volcanology, hydrothermal activity, and sulfide mineralogy of several active and dormant volcanoes in the southern Mariana Arc (eg., Tracey, E. Diamante, NW and W Rota, and Zealandia). A broad band ocean bottom seismometer instrument package is likely to be deployed on the NW-Rota-1 for 10days. Rock samples will be collected for future petrographic analyses. Broader impacts:This project provides a strong international collaboration between US and Japanese scientists and thus promotes cross scientific exchange within the IODP. It involves 7 US scientists and students from four universities, including two female scientists. The project will assist the research of three graduate students, and provide them a hands-on opportunity for sample collection and direct exchange with an international team of scientists.

该项目将利用预定的JAMSTEC巡航，其中包括10次前往马里亚纳火山的研究潜水。本次研究巡航的两个主要目标是了解1）俯冲开始期间IBM前弧的演变，以及2）活跃的现代海底弧的火成岩和热液活动。这项工作将调查马里亚纳弧南部几个活火山和休眠火山的海底火山学、热液活动和硫化物矿物学（例如，Tracey，E. Diamante、NW和W Rota以及Zealandia）。一个宽带海底地震仪仪器包可能会部署在西北-罗塔-1为期10天。将收集岩石样本用于未来的岩相分析。更广泛的影响：该项目为美国和日本科学家提供了强有力的国际合作，从而促进了IODP内部的跨科学交流。该项目涉及7名美国科学家和来自4所大学的学生，其中包括两名女科学家。该项目将协助三名研究生的研究，并为他们提供一个动手收集样本和与国际科学家小组直接交流的机会。
