Collaborative Research: Future Directions for Seafloor Geodesy Workshop 2020

本次研讨会将汇集现有和新兴科学界的成员，他们对使用海底大地测量工具进行海底变形感兴趣。该研讨会将提供第一个促进科学家和工程师之间交流的机会，以探索如何利用现有资源来最大限度地实现科学目标。大地测量仪器可以捕捉到海上的运动，让我们对地震和海底火山活动有了重要的了解。这次研讨会的重点是海底变形，因为地球上90%的活动构造板块边界都在水下，而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。这一点在俯冲带尤其重要，因为在那里，地震时断层上的运动可能会引发海啸。这次会议将有90名与会者。这次会议的时机很重要，因为一种新的资源正在为该社区开发，一套海底大地测量仪器，可以测量精确的长期水平和短期垂直运动。在研讨会上，业界将讨论如何应用这些资源来最大限度地提高科学和数据的可访问性，从而为未来的海上项目提出建议。讲习班将扩大对海底大地测量学领域的参与，许多参加者将是早期职业科学家。研讨会将提供一个机会来促进科学家和工程师之间的联系。本次研讨会将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，他们专注于理解与测量海底变形相关的科学和工程问题。在研讨会期间，组织者将讨论该领域现有技术的现状、新兴技术的发展以及未来技术的计划。此外，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底压记录仪海底大地测量仪器池的计划也至关重要。讲习班将确定该仪器库的高优先科学问题和目标，以及社区首选的管理仪器库的结构。该社区将帮助确定仪器池可解决的最优先科学问题和目标，并制定管理设备的计划，以有效地回答海洋环境中地球变形的地球物理问题。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

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.
