Collaborative Research: USA-Japan-Australia Geophysical Investigation of the Ontong Java Plateau

9903454 Coffin该奖项支持澳大利亚地质调查局研究人员与德克萨斯大学奥斯汀分校地球物理研究所的Mike Coffin和博士后Tadeusz Gladczenko在地震成像和海洋钻探计划地面真实方面的合作研究。该项目是对由开放式教育中心9714368资助的工作的补充。南印度洋的科尔盖伦高原和西太平洋的安通爪哇高原是地球上已知的两个最大的洪水玄武岩省份，每个省份的面积都大约是毗邻的美国的三分之一。通过重点开展的地球物理和科学钻探计划，PIS正试图更好地了解导致它们形成的地幔过程、它们的火山和深成岩历史，以及它们与全球环境和生物变化的关系。在Kerguelen和Onton Java高原上进行多道地震反射工作，然后对这两个特征进行科学钻探，试图解决悬而未决的科学问题。这项工作计划涉及与澳大利亚地质调查局的科学家为期三个月的合作，该组织拥有Kerguelen高原上11个ODP点中大部分的多道地震剖面。虽然这些数据通常只供购买，但通过合作项目，美国PI和博士后将能够访问这些数据和相关的地球物理数据，这些数据将被分析和公布，从而在这一过程中向科学界提供对关键数据的重要访问。

9903454CoffinThis award supports cooperative research on seismic imaging and Ocean Drilling Program ground truthing between Australian Geological Survey Organization researchers and Mike Coffin and post-doc Tadeusz Gladczenko from the University of Texas at Austin's Institute for Geophysics. This project is supplementary to work funded under OCE 9714368. The Kerguelen Plateau in the southern Indian Ocean and the Ontong Java Plateau in the western Pacific ocean are the two largest flood basalt provinces known on Earth, each being approximately one-third the size of the contiguous United States. Through focused geophysical and scientific drilling programs on each, the PIs are attempting to understand better the mantle processes responsible for their formation, their volcanic and plutonic histories, and their relationships to global environmental and biotic change. Multichannel seismic reflection work on the Kerguelen and Onton Java plateaus, followed by scientific drilling of the two features are attempting to address the outstanding scientific problems.The work plan involves a three-month collaboration with scientists at the Australian Geological Survey organization, which has multichannel seismic profiles of the majority of the eleven ODP sites on the Kerguelen Plateau. While these data are typically available only for purchase, through the collaborative project the U.S. PI and post-doc will have access to the data and to associated geophysical data which will be analyzed and published providing important access to key data to the scientific community in the process.
