Collaborative Proposal: How Did the "World's Largest Single Volcano" Form at a Triple Junction? A Magnetic and Bathymetry Survey of Tamu Massif, Shatsky Rise

提出的工作将试图更好地了解塔木地块的形成，塔木地块是沙斯基隆升海洋高原的主要火山大厦。2015年秋季，施密特海洋研究所（Schmidt Ocean Institute）的研究船Falkor将在Tamu地块上进行为期32天的巡航，通过收集和分析磁异常和水深数据来完成这项工作。该项目将支持一名早期职业女性研究者，并促进与日本的国际合作。研究生和本科生都将参与航海体验。该项目将有一个外联部分，包括学习模块，让学生了解海底火山、海洋地质学和地球物理学，以及与博物馆合作，通过向船上提供视频馈送来创建展览。本项目将检验沙斯基隆起塔木地块形成的两种端元假设：1)塔木地块是新地幔柱形成时从核幔边界区域产生的大量热浮力物质的结果(？羽头?假设);2)塔木地块是高原喷发的结果，在那里板块边界或板块裂缝释放了熔融温度较低的上地幔区域上方的压力。地幔假说)。该项目的结果将允许对现有磁异常图进行修订，并对构造和构造解释进行修订。该项目将有一个外联部分，由莱斯利·皮尔特组织，他是IODP海洋领导联盟的前外联协调员，目前在科珀斯克里斯蒂水族馆工作。潜在的外展活动包括学生用来学习海底火山、海洋地质学和地球物理学的学习模块，以及与博物馆合作制作带有视频馈送到船上的展览。

Part 1The proposed work will attempt to gain a better understanding of the formation of Tamu Massif, the main volcanic edifice of Shatsky Rise oceanic plateau. This will be accomplished by collecting and analyzing magnetic anomaly and bathymetric data over Tamu Massif during of a 32-day cruise on the Schmidt Ocean Institute research vessel Falkor in the fall of 2015. The project will support an early-career female investigator and promote international collaboration with Japan. Graduate students as well as undergraduates will be involved in the sea-going experience. The project will have an outreach component consisting of learning modules for students to learn about submarine volcanoes and marine geology and geophysics as well as partnering with museums to create exhibits with video feeds to the ship.Part 2This project will test two end-member hypotheses about the formation of Tamu Massif on the Shatsky Rise: 1) that Tamu Massif is the result of a large mass of thermally-buoyant material arising from the core-mantle boundary region as a new mantle plume is formed (?plume head? hypothesis); or 2) that Tamu Massif is the result of plateau eruptions occurring where plate boundaries or plate cracks release pressure above areas of the upper mantle with lower melting temperatures (?fertile? mantle hypothesis). The project results will allow for the revision of the existing map of magnetic anomalies and the revision of the tectonic and structural interpretation. The project will have an outreach component that will be organized by Leslie Peart, former outreach coordinator for Consortium for Ocean Leadership for IODP, who currently works for the Corpus Christi Aquarium. Potential outreach activities consist of learning modules for students to use to learn about submarine volcanoes and marine geology and geophysics as well as partnering with museums to create exhibits with video feeds to the ship.
