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

第1部分工作将试图更好地了解塔木地块的形成，塔木地块是沙茨基隆起大洋高原的主要火山建筑物。这将通过在2015年秋季施密特海洋研究所研究船Falkor上进行为期32天的巡航期间收集和分析Tamu Massif上空的磁异常和水深数据来实现。该项目将支持一名职业生涯早期的女性调查员，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。该项目将有一个外展部分，由学习模块组成，供学生学习海底火山、海洋地质学和地球物理学，并与博物馆合作，以视频形式制作展品到船上。第二部分本项目将检验关于沙茨基隆起塔木地块形成的两个最终成员假说：1)塔木地块是核幔边界区域形成新的地幔热柱(？热柱头部？)的大量热浮物质的结果。假设)；或2)塔木地块是高原喷发的结果，其中板块边界或板块裂缝在熔融温度较低的上地幔区域上方释放压力(富饶？地幔假说)。该项目的成果将有助于修订现有的磁异常图，并修订构造和构造解释。该项目将有一个外联部分，由前IODP海洋领导联盟外联协调员Leslie Peart组织，目前在Corpus Christi水族馆工作。潜在的外展活动包括供学生用来了解海底火山、海洋地质学和地球物理学的学习单元，以及与博物馆合作制作展览，并向船上提供视频。

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.
