Central Atlantic Lithosphere-Asthenosphere Boundary Study

中大西洋岩石圈-软流圈边界研究

基本信息

项目摘要

Part 1The award will enable the U.S. scientists to join a large, multi-institution, multi-disciplinary European project to collect geophysical data in the mid-Atlantic Ocean to study the lithosphere-asthenosphere boundary (LAB) in the deep Earth. European scientists will deploy instruments to collect earthquake and related data. With funds from this proposal, the US scientists will deploy electro-magnetic instruments, and all of the types of data to be gathered will allow imaging the LAB at different length scales. The impact of this research will be far reaching, both in the scientific as well as in the technical domain. The results would help in resolving an important scientific controversy about the lithosphere and shed light on the thermal structure of oceanic mantle. Outreach is planned at Scripps? Birch Aquarium and student support is also included.Part 2This project is to allow the U.S. PIs to join a large, multi-institution, multi-disciplinary European initiative to collect geophysical data in the mid-Atlantic to characterize the lithosphere-asthenosphere boundary (LAB) as a function of age. European collaborators will deploy 30 OBS for a year to collect teleseismic, surface wave, and receiver function data. In addition, deep seismic reflection data will be acquired by Schlumberger using state-of-the-art industry equipment on a continuous profile along a stream-line from the mid-Atlantic to 100 My crust. Under funding from this proposal, the PIs plan to deploy 40 Scripps broadband MT instruments at OBS sites. Satish Singh of IPGP has already secured funding for the seismic reflection study, as well as a commitment from Schlumberger. Catherine Rychert and Nicholas Harmon of University of Southampton have secured funding for the passive seismic deployments, as well as ship time. The MT deployments and recoveries will piggy-back the Southampton experiment, but data will be integrated across the three studies. The results would help in resolving an important scientific controversy about the lithosphere and shed light on the thermal structure of oceanic mantle. Outreach is planned at Scripps' Birch Aquarium and student support is also included.
该奖项将使美国科学家能够加入一个大型、多机构、多学科的欧洲项目,在大西洋中部收集地球物理数据,研究地球深处的岩石圈-软流圈边界(LAB)。欧洲科学家将部署仪器收集地震和相关数据。利用这项提案的资金,美国科学家将部署电磁仪器,收集到的所有类型的数据将允许对实验室进行不同长度尺度的成像。这项研究的影响将是深远的,无论是在科学领域还是在技术领域。这一结果将有助于解决关于岩石圈的一个重要科学争议,并揭示海洋地幔的热结构。斯克里普斯有外展计划吗?桦树水族馆和学生支持也包括在内。该项目允许美国pi加入一个大型、多机构、多学科的欧洲倡议,在大西洋中部收集地球物理数据,以表征岩石圈-软流圈边界(LAB)作为年龄的函数。欧洲合作者将部署30台地震仪,为期一年,收集远震、面波和接收器功能数据。此外,斯伦贝谢将使用最先进的工业设备,在从大西洋中部到100米地壳的流线上连续剖面上获取深层地震反射数据。在该提案的资助下,pi计划在OBS站点部署40台斯克里普斯宽带MT仪器。IPGP的Satish Singh已经获得了地震反射研究的资金,以及斯伦贝谢的承诺。南安普顿大学的Catherine Rychert和Nicholas Harmon已经为被动地震部署和船舶时间获得了资金。MT的部署和恢复将与南安普顿的实验密切相关,但数据将整合到三个研究中。这一结果将有助于解决关于岩石圈的一个重要科学争议,并揭示海洋地幔的热结构。外展计划在斯克里普斯的桦树水族馆进行,学生支持也包括在内。
