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(肖)1927373(特威迪)永久冻土海岸系统是地球系统中变化最快的组成部分之一。永久冻土海岸系统网络(PERS-NET)项目将通过连接十多个现有的国家和国际网络，填补与北极受永久冻土影响的海岸相关的科学、工程和社会问题方面的基本知识空白。Percs-Net将使我国与国际合作者并驾齐驱，为新的研究社区提供动力，使北极研究人员多样化，参与知识的联合生产，并促进应对不断变化的北极的已知和正在出现的挑战所需的长期团队科学。这一网络网络将制定国际公认的议定书，以量化和综合关于沿海永久冻土系统发生的影响的信息。它还将提供一个框架，以评估当地和全球经济面临的风险，并转让将导致北极地区适应战略的知识。PERC-Net将促进网络之间的协同，以培养下一代学生、博士后学者和职业生涯早期的研究人员，他们负责确定北极系统发生的变化的潜在解决方案。没有任何地方比北极更能代表自然、社会和已建系统的交汇处所面临的挑战。PERS-Net将开发一个跨学科的伞形网络，以协同现有的数据集，扩大空间和时间上的观测，整合现场传感技术，协调网络之间的目标，并参与综合努力。新的知识将为政府间机构以及国际研究和推广计划提供信息，以做出以科学为基础的决策和政策，以适应永冻土海岸系统的动态。网络活动包括在国家和国际地点举行的年度面对面会议、每月网络研讨会会议、在北极沿海社区的外联、综合出版物以及学生和职业早期研究人员人员交流。PERC-Net的预期成果将整合到一个框架中，由跨政治、文化和学科边界合作的个人和组织提供变革性的知识共享，以解决关键的科学、工程和社会问题，以应对不断变化的北极永冻土沿海系统。通过国际网络对网络合作加速研究(AccelNet)计划旨在加快科学发现的进程，并为多团队国际合作培养下一代美国研究人员。AccelNet计划支持美国研究网络和海外互补网络之间的战略联系，这些网络将利用研究和教育资源来应对需要重大协调国际努力的重大科学挑战。该项目由极地计划办公室的北极系统科学计划共同资助。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
