Collaborative EAGER project: Early Career Seismic Chief Scientist Training Cruise

最近联合国最低限度海洋地震调查问卷(MSQ)的结果表明，早期职业科学家多渠道地震(MCS)首席科学家培训巡航的价值。提议并授予了开展海洋监测监测系统培训方案的资金，该方案包括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人数，并展示斯克里普斯海洋研究所便携式监测监测系统的价值，该系统是联合国内罗毕办事处的一个设施。培训方案由三部分组成：(1)巡航前的网络研讨会，使参与者了解活跃震源海洋地震学的基本知识，提供有效规划即将进行的调查所需的科学背景，并向参与者介绍开放源码处理和解释工具。网络研讨会将包括建议书撰写和数据管理培训。在网络研讨会系列结束后，将征集申请，包括最多两页的科学提案。一旦选定，参与者将在巡航前研讨会之前通过几次网真会议与PI团队讨论他们的邮轮计划；然后，在邮轮之前为期两天的研讨会上，参与者将在PI团队的指导下敲定邮轮计划；(Ii)培训邮轮。每个参与者将帮助整个团队带着叠后时间迁移的数据走下船，并共同撰写巡航报告；以及(Iii)利用基于计算机的可视化软件举办为期两天的数据解释讲习班。智力优势：拟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。在俄勒冈州海岸外延伸的大陆边缘，从这次巡航中获得、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吸积脊和含有古海洋信息的半洋沉积物。目标对解决重要的社会相关问题有影响，例如地震灾害和盆地的古气候记录。还有可能使用地震技术来揭示东北太平洋边界上升区周围水柱内的实时、精细尺度。来自这次巡航的开放获取数据可以增强更广泛的社区进行的正在进行的和不久的将来的科学。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者池中挑选出来。这项科学任务将在MSQ和其他地球科学名单上做广告，并通过诸如奇卡诺人/西班牙裔美国人促进会和美洲原住民科学促进会和地球科学妇女网络等组织促进机会，鼓励代表不足的少数群体和妇女参加。参与者不仅将获得第一手地震巡航体验，还将体验到与非科学家交流他们的研究成果。拟议的活动将用于向公众宣传地震研究对解决各种重要的社会挑战所做出的独特而重要的贡献。结果将在AGU的GeSpace博客和Instagram账户上分享。邮轮前和船上活动对社区的重要交付成果是建立和提供这次邮轮期间使用的开放源代码软件的“食谱”；一旦从邮轮上获得的数据在公众可访问的档案馆存档后立即开放。将与联合国后勤基地办事处合作进行一次巡航后调查，以获得参与者的反馈，并鼓励参与者编写国家科学基金提案，其数量将是对这一环境方案成功的直接和最终衡量。

Results of the recent UNOLS Marine Seismic Questionnaire (MSQ) demonstrate the value of an early career 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 scientists experienced in marine seismology and to demonstrate the value of the Scripps Institution of Oceanography 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 marine seismology, to provide the scientific background needed to plan the upcoming survey effectively, and to introduce the participants to open source processing and interpretation tools. The Webinars will include Proposal 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 plans with the PI team prior to the pre-cruise workshop via several telepresence meetings; then, during a 2-day workshop immediately before the cruise, the participants will finalize the cruise plan under the PI team's guidance; (ii) A training cruise. Each participant will contribute to the entire team walking off the ship with post-stack time migrated data, as well as writing a cruise report collaboratively; and (iii) a 2-day data interpretation 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 wide range of participants. At the extended continental margin off the coast of Oregon, the seismic reflection profiles acquired, processed, and archived from this cruise can be used to image the subducting plate and the Astoria Fan, as well as accretionary ridges hosting gas hydrate and pockets of hemipelagic sediment containing paleo-oceanographic information. Targets have implications for addressing important societally relevant questions, such as earthquake hazards and paleoclimate records in basins. There will also be potential for using seismic techniques to reveal real-time, fine-scale within the water column around upwelling regions of the northeastern Pacific Ocean boundaries. Open access data from this cruise can 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 participations of underrepresented minorities and women by promoting the opportunity via organizations such as Society for Advancement of Chicanos/Hispanics and Native Americans in Scienceand Earth Science Women's Network. Participants will gain not only first-hand seismic cruise experience but also experience communicating their research to non-scientists. The proposed activities will be used to inform the public about the unique and essential contributions of seismic research toward solving a variety of important societal challenges. Results will be shared on the AGU's GeoSpace blog and Instagram account. Important deliverables from the pre-cruise and onboard activities to the community are to establish and provide "cookbook" of the open source software used during this cruise; and make the data acquired from the cruise open immediately as soon as they are archived at the publically accessible archives. A post-cruise survey will be conducted in collaboration with the UNOLS office to obtain feedback from the participants and encourage the participants to write NSF proposals, the number of which will be the direct and ultimate measurement of the success of this ECS.
