Central Atlantic Lithosphere-Asthenosphere Boundary Study

第 1 部分 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，收集大西洋中部的地球物理数据，以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来收集地震和相关数据。借助该提案的资金，美国科学家将部署电磁仪器，收集的所有类型的数据将允许在不同长度尺度上对实验室进行成像。这项研究的影响将在科学和技术领域产生深远的影响。这些结果将有助于解决有关岩石圈的重要科学争议，并揭示大洋地幔的热结构。斯克里普斯计划开展外展活动吗？还包括 Birch 水族馆和学生支持。第 2 部分该项目旨在让美国 PI 加入一项大型、多机构、多学科的欧洲计划，收集大西洋中部的地球物理数据，以将岩石圈-软流圈边界 (LAB) 描述为年龄的函数。欧洲合作者将部署 30 个 OBS，为期一年，用于收集远震、表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，沿着从大西洋中部到 100 My 地壳的流线连续剖面采集深地震反射数据。在该提案的资助下，PI 计划在 OBS 站点部署 40 台 Scripps 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。南安普顿大学的凯瑟琳·里切特（Catherine Rychert）和尼古拉斯·哈蒙（Nicholas Harmon）已为被动地震部署和船舶时间获得了资金。 MT 的部署和回收将搭载南安普顿实验，但三项研究的数据将被整合。这些结果将有助于解决有关岩石圈的重要科学争议，并揭示大洋地幔的热结构。计划在斯克里普斯伯奇水族馆进行外展活动，还包括学生支持。

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.
