Collaborative EAGER project: Early Career Seismic Chief Scientist Training Cruise

点击翻译按钮获取中文摘要

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.
