Collaborative EAGER project: Early Career Seismic Chief Scientist Training Cruise

最近联合国生命线行动海洋地震调查问卷（MSQ）的结果证明了早期职业科学家多通道地震（MCS）首席科学家培训巡航的价值。拟议和授予的资金用于开展MCS培训计划，其中包括4天的地震数据采集，以增加在海洋地震学方面有经验的早期职业科学家的数量，并展示斯克里普斯海洋学研究所便携式MCS系统（UNOLS设施）的价值。培训计划由三个部分组成：(i)邮轮前的网络研讨会，让参与者了解海洋活源地震学的基础知识，提供有效规划即将到来的调查所需的科学背景，并向参与者介绍开源处理和解释工具。网络研讨会将包括提案写作和数据管理培训。在网络研讨会系列之后，将征集申请，包括最多2页的科学提案。一旦被选中，参与者将通过几次网真会议在巡航前研讨会之前与PI团队讨论他们的巡航计划；然后，在巡游前两天的工作坊中，参与者将在PI团队的指导下完成巡游计划；训练巡航。每个参与者将为整个团队提供堆栈后时间迁移数据，并协作编写巡航报告；（iii）利用计算机可视化软件进行为期两天的数据解释研讨会。知识价值：建议的调查区域位于美国西海岸的活跃大陆边缘，那里有各种沉积和构造环境，为广泛的参与者提供了感兴趣的目标。在俄勒冈海岸外的扩展大陆边缘，从这次航行中获得、处理和存档的地震反射剖面可以用来成像俯冲板块和阿斯托里亚扇，以及含有天然气水合物的增生脊和含有古海洋学信息的半深海沉积物。目标对于解决重要的社会相关问题具有意义，例如地震灾害和盆地的古气候记录。此外，利用地震技术还可以实时、精细地揭示东北太平洋边界上升流区域周围的水柱。这次巡查的开放获取数据可以扩大正在进行的和不久的将来由更广泛的社区进行的科学研究。更广泛的影响：对于这个新颖的，变革性的项目，早期职业科学家将从广泛的申请人池中选择。这项科学任务将在MSQ和其他地球科学网站上进行宣传，并通过诸如墨西哥裔美国人/西班牙裔美国人科学促进会和地球科学妇女网络等组织促进机会，鼓励未被充分代表的少数民族和妇女参与。参与者不仅可以获得第一手的地震巡航经验，还可以向非科学家交流他们的研究。拟议的活动将用于向公众宣传地震研究对解决各种重要社会挑战的独特和重要贡献。结果将在AGU的GeoSpace博客和instagram账户上分享。从巡航前和船上活动到社区的重要交付成果是建立和提供巡航期间使用的开源软件的“食谱”；从游轮上获得的数据一旦被归档到公众可访问的档案馆，就立即对外开放。巡航后调查将与unools办公室合作进行，以获得参与者的反馈，并鼓励参与者撰写NSF提案，这些提案的数量将是本次ECS成功与否的直接和最终衡量标准。

Results of the recent UNOLS Marine Seismic Questionnaire (MSQ) demonstrate the value of an earlycareer scientist Multi-Channel Seismic (MCS) chief scientist training cruise. Proposed, and awarded, are funds to carry out a MCS training program that includes 4 days of seismic data acquisition to increase the number of early career scientistsexperienced in marine seismology and to demonstrate the value of the Scripps Institution ofOceanography portable MCS system, a UNOLS facility. The training program consists of three parts: (i)Webinars prior to the cruise to expose the participants to the fundamentals of active source marineseismology, to provide the scientific background needed to plan the upcoming survey effectively, and tointroduce the participants to open source processing and interpretation tools. The Webinars will includeProposal Writing and Data Management training. Applications will be solicited, including a maximum 2-page science proposal, after the webinar series. Once selected, participants will discuss their cruise planswith the PI team prior to the pre-cruise workshop via several telepresence meetings; then, during a 2-dayworkshop immediately before the cruise, the participants will finalize the cruise plan under the PI team'sguidance; (ii) A training cruise. Each participant will contribute to the entire team walking off the shipwith post-stack time migrated data, as well as writing a cruise report collaboratively; and (iii) a 2-day datainterpretation workshop with computer-based visualization software.Intellectual Merit:The proposed survey regions are on the active continental margin of the west coast of the United States,where a variety of sedimentary and tectonic settings are available, providing targets of interest to a widerange of participants. At the extended continental margin off the coast of Oregon, the seismic reflectionprofiles acquired, processed, and archived from this cruise can be used to image the subducting plate andthe Astoria Fan, as well as accretionary ridges hosting gas hydrate and pockets of hemipelagic sedimentcontaining paleo-oceanographic information. Targets have implications for addressing importantsocietally relevant questions, such as earthquake hazards and paleoclimate records in basins. There willalso be potential for using seismic techniques to reveal real-time, fine-scale within the water columnaround upwelling regions of the northeastern Pacific Ocean boundaries. Open access data from this cruisecan augment on-going and near-future science conducted by a broader community.Broader Impacts:For this novel, transformative project, early-career scientists will be selected from a wide applicant pool.This science mission will be advertised on the MSQ and other geoscience listservs, and encouraged participationsof underrepresented minorities and women by promoting the opportunity via organizations such asSociety for Advancement of Chicanos/Hispanics and Native Americans in Scienceand Earth ScienceWomen's Network. Participants will gain not only first-hand seismic cruise experience but alsoexperience communicating their research to non-scientists. The proposed activities will be used to informthe public about the unique and essential contributions of seismic research toward solving a variety ofimportant societal challenges. Results will be shared on the AGU's GeoSpace blog and Instagramaccount. Important deliverables from the pre-cruise and onboard activities to the community are toestablish and provide "cookbook" of the open source software used during this cruise; and make the dataacquired from the cruise open immediately as soon as they are archived at the publically accessiblearchives. A post-cruise survey will be conducted in collaboration with the UNOLS office to obtainfeedback from the participants and encourage the participants to write NSF proposals, the number ofwhich will be the direct and ultimate measurement of the success of this ECS.
