1927553 (Jones) 1927137 (Xiao) 1927373 (Tweedie) Permafrost coastal systems are one of the most rapidly changing components of the Earth's systems. The Permafrost Coastal Systems Network (PerCS-Net) project will fill fundamental knowledge gaps in science, engineering, and societal issues associated with permafrost-affected coasts in the Arctic by linking over ten existing national and international networks. PerCS-Net will position our nation alongside international collaborators to empower new research communities, diversify Arctic researchers, engage in the co-production of knowledge, and promote long-lasting team science required to face the known and emerging challenges of the changing Arctic. This network of networks will develop internationally recognized protocols for quantifying and synthesizing information on the impacts occurring in coastal permafrost systems. It will also provide a framework to assess risks to local and global economies and to transfer knowledge that will lead to adaptation strategies across Arctic regions. PerCS-Net will promote synergy across networks to foster the next generation of students, postdoctoral scholars, and early-career researchers charged with identifying potential solutions to changes occurring in the Arctic system. There is no place more representative of the challenges faced at the intersection of natural, social, and built systems than the Arctic. PerCS-Net will develop a transdisciplinary umbrella network to synergize existing datasets, expand observations in space and time, integrate in-situ sensing techniques, coordinate goals among networks, and engage in synthesis efforts. The new knowledge will inform intergovernmental agencies as well as international research and outreach programs to make science-based decisions and policies in adapting to permafrost coastal system dynamics. Network activities include annual in-person meetings at national and international venues, monthly webinar meetings, outreach in Arctic coastal communities, synthesis publications, and student and early-career researcher personnel exchanges. Expected outcomes of PerCS-Net will integrate into a framework for transformative knowledge sharing from individuals and organizations cooperating across political, cultural, and disciplinary borders to address critical science, engineering, and social issues in response to permafrost coastal systems in the changing Arctic. The Accelerating Research through International Network-to-Network Collaborations (AccelNet) program is designed to accelerate the process of scientific discovery and prepare the next generation of U.S. researchers for multiteam international collaborations. The AccelNet program supports strategic linkages among U.S. research networks and complementary networks abroad that will leverage research and educational resources to tackle grand scientific challenges that require significant coordinated international efforts. This project was co-funded by the Arctic System Science Program in the Office of Polar Programs.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.

1927553（琼斯）1927137（xiao）1927373（Tweedie）永久冻土沿海系统是地球系统中最快变化的组成部分之一。永久冻土沿海系统网络（PERCS-NET）项目将填补科学，工程和社会问题的基本知识差距，并通过连接十个现有的国家和国际网络，与北极的多年冻土影响沿岸相关。 PERCS-NET将与国际合作者一起定位我们的国家，以增强新的研究社区的能力，使北极研究人员多样化，参与知识的共同生产，并促进面对不断变化的北极地区已知和新兴挑战所需的持久团队科学。该网络网络将开发国际认可的协议，以量化和综合有关沿海多年冻土系统影响的信息。它还将提供一个框架，以评估当地和全球经济体的风险，并转移知识，从而导致北极地区的适应策略。 PERCS-NET将促进整个网络的协同作用，以培养下一代学生，博士后学者以及早期职业研究人员，负责确定北极系统中发生的变化的潜在解决方案。与北极相比，自然，社会和建筑系统交汇处所面临的挑战没有更多的代表。 PERCS-NET将开发一个跨学科的雨伞网络，以协同现有数据集，扩展时空的观察结果，集成原位感应技术，协调网络之间的目标并参与综合工作。新知识将为政府间机构以及国际研究和外展计划提供信息，以适应永久冻土沿海系统动态，以做出基于科学的决策和政策。网络活动包括在国家和国际场所举行的年度面对面会议，每月网络研讨会，北极沿海社区的外展，综合出版物以及学生和早期职业研究员的人事交流。 PERCS-NET的预期结果将融入一个框架中，用于从政治，文化和学科边界合作的个人和组织的变革性知识共享，以解决北极地区不断变化的沿海沿海体系的批判科学，工程和社会问题。通过国际网络到网络合作（ACCELNET）计划进行加速研究旨在加速科学发现的过程，并为下一代美国研究人员做好了多次国际合作的准备。 Accelnet计划支持美国研究网络和国外互补网络之间的战略联系，这将利用研究和教育资源来应对需要大量协调国际努力的宏伟科学挑战。该项目是由北极系统科学计划在极地计划办公室共同资助的。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响评估标准，被视为值得通过评估来获得支持。
