Collaborative Research: Future Directions for Seafloor Geodesy Workshop 2020

该讲习班将汇集对使用海底大地测量工具进行海底变形感兴趣的现有和新兴科学界的成员。 研讨会将首次提供机会，促进科学家和工程师之间的交流，探讨如何利用现有资源最大限度地实现科学目标。 大地测量仪器可以捕捉到近海的运动，这使我们对地震和海底火山活动有了重要的了解。 研讨会的重点是海底变形，因为地球90%的活动构造板块边界都在水下，我们测量导致地震的变形的能力主要是在陆地上，这并不能捕捉到大部分海底运动。这一点在沿着俯冲带尤其重要，在那里，地震时断层的运动可能会产生海啸。会议将有90名与会者。这次会议的时间安排很重要，因为正在为共同体开发一种新的资源，即一套海底大地测量仪器，可以精确测量长期水平和短期垂直运动。 在研讨会上，社区将讨论如何应用这些资源，以最大限度地提高科学和数据的可访问性，从而为未来的离岸项目提出建议。 该讲习班将扩大海底大地测量领域的参与，相当多的参与者将是初出茅庐的职业科学家。该讲习班将为促进科学家和工程师之间的联系提供一个机会，汇集并建立海底大地测量界，包括来自学术机构、政府机构和国际合作伙伴的科学家，他们的重点是了解与测量海底变形有关的科学和工程问题。 在研讨会期间，组织者将讨论现有技术的现状，新兴技术的发展以及该领域未来技术的计划。此外，该讲习班对于制定使用最近资助的全球导航卫星系统声学和海底压力记录仪海底大地测量仪器库的计划至关重要。 讲习班将确定高优先级的科学问题和目标，为这一池的仪器和社区首选的结构，以管理仪器池。该团体将帮助确定最高优先级的科学问题和目标可寻址的仪器池，并制定一个计划，管理设备，以有效地回答地球物理问题，在地球变形在近海环境中。这个奖项反映了NSF的法定使命，并已被认为是值得的支持，通过评估使用基金会的智力价值和更广泛的影响审查标准。

This workshop will bring together members of the established and emerging scientific community interested in seafloor deformation using geodetic tools deployed on the seafloor. The workshop will offer the first opportunity to foster communications between scientists and engineers to explore how to utilize existing resources to maximize science goals. Geodetic instruments can capture motions offshore that give us important insight into earthquakes and submarine volcanic activity. The workshop is focused on seafloor deformation because ninety percent of Earth's active tectonic plate boundaries are underwater and our ability to measure the deformation that leads up to an earthquake is predominantly on-land, which doesn’t capture most of the seafloor movement. This is particularly important along subduction zones, where tsunamis may be generated by the movement on a fault during an earthquake. The conference will include 90 participants. The timing of the conference is important because a new resource is being developed for the community, a set of seafloor geodetic instruments that can measure precise long-term horizontal and short-term vertical movements. At the workshop, the community will discuss how to apply these resources to maximize science and accessibility of data, leading to proposals for future offshore projects. The workshop will broaden participation in the field of seafloor geodesy and a significant number of the participants will be early career scientists. The workshop will offer an opportunity to foster connections between scientists and engineers.This workshop will bring together and build the seafloor geodesy community, including scientists from academic institutions, government agencies, and international partners focused on understanding scientific and engineering problems associated with measuring deformation on the seafloor. During the workshop the organizers will address the current status of existing, the development of emerging, and plans for future technologies in the field. As well, the workshop is essential to develop plans for the use of a recently funded pool of GNSS-Acoustic and Bottom Pressure Recorder seafloor geodetic instruments. The workshop will identify high priority scientific questions and targets for this pool of instruments and the community preferred structure for managing the instrument pool. The community will help identify the highest priority scientific questions and targets addressable with the instrument pool and develop a plan for managing the equipment to effectively answer geophysical questions in earth deformation in the offshore environment.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
