Collaborative EAGER project: Early Career Seismic Chief Scientist Training Cruise

联合国海洋法办事处最近的海洋地震调查表（MSQ）的结果表明，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。拟议并已发放资金，用于开展监测、监控和监视培训方案，其中包括为期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学研究所便携式监测、监控和监视系统（联合国海洋和海洋法办事处的一个设施）的价值。培训方案包括三个部分：㈠在航行前举行网络研讨会，向参加者介绍主动源海洋地震学的基本原理，提供有效规划即将进行的调查所需的科学背景，并向参加者介绍开放源码处理和解释工具。网络研讨会将包括提案写作和数据管理培训。申请将征求，包括最多2页的科学建议，网络研讨会系列后。一旦选定，参与者将在航行前讲习班之前通过几次远程呈现会议与主要参与者小组讨论其航行计划;然后，在航行前的为期两天的讲习班期间，参与者将在主要参与者小组的指导下最后确定航行计划; ㈡培训航行。每个参与者将协助整个团队带着叠后时间迁移数据下船，并合作编写航行报告; ㈢为期2天的数据解释讲习班，使用计算机可视化软件。智力优势：拟议的调查区域位于美国西海岸的活动大陆边，那里有各种沉积和构造背景，为广大参与者提供了感兴趣的目标。在俄勒冈州海岸外的扩展大陆边，这次巡航获得、处理和存档的地震反射剖面可用于对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远洋沉积物袋成像。目标对解决重要的社会相关问题具有影响，如地震灾害和盆地的古气候记录。还将有可能利用地震技术来揭示东北太平洋边界上涌区域周围水柱内的实时、精细尺度。这次航行的开放获取数据可以增强更广泛社区正在进行的和不久的将来进行的科学。更广泛的影响：对于这个新颖的，变革性的项目，早期的职业科学家将从广泛的申请者中选出。这一科学使命将在MSQ和其他地球科学邮件列表上做广告，并通过促进墨西哥裔/西班牙裔和美洲原住民科学学会和地球科学妇女网络等组织宣传这一机会，鼓励代表性不足的少数民族和妇女参与。参与者不仅将获得第一手的地震巡航经验，而且还将获得向非科学家传达其研究成果的经验。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。航行前和船上活动向社区提供的重要成果是建立和提供这次航行中使用的开放源码软件的“食谱”;以及在航行中获得的数据一旦存档在可访问的档案中，立即开放。将与联合国日内瓦办事处合作进行一次航行后调查，以获得参与者的反馈，并鼓励参与者编写国家科学基金会的提案，提案的数量将是衡量该环境合作战略是否成功的直接和最终尺度。

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.
