Navigating the New Arctic (NNA) is one of NSF's 10 Big Ideas. NNA projects address convergence scientific challenges in the rapidly changing Arctic. This Arctic research is needed to inform the economy, security and resilience of the Nation, the larger region and the globe. NNA empowers new research partnerships from local to international scales, diversifies the next generation of Arctic researchers, enhances efforts in formal and informal education, and integrates the co-production of knowledge where appropriate. This award fulfills part of that aim by addressing interactions among social systems and the natural environment in the following NNA focus areas: Data and Observation, Education, Forecasting, Global Impact, and Resilient Infrastructure.Rapid Arctic warming is altering circulation in the North Atlantic Ocean. Resulting changes in marine ecosystems could potentially undermine regional fisheries along the coasts of New England and Atlantic Canada. These changes will present new challenges and opportunities to coastal communities. This NNA Research project focuses on links between Arctic change and the iconic American lobster (Homarus americanus) fishery. The lobster fishery is the most valuable single-species fishery in North America. It is also a well-studied socio-ecological system, making it a good subject for convergence research. The project builds a NNA Lobster Network based on cross-sector and cross-border partnerships. The project develops a climate vulnerability assessment focused on the northward geographic range shifts of lobsters in a warming ocean. This project is producing new knowledge to understand the links among climate-induced Arctic change, lower latitude marine ecosystems, and an iconic fishery in the Northwest Atlantic. This collaborative project tests two overarching hypotheses: (1) climate-driven Arctic change will affect the distribution and abundance of American lobster stocks, and (2) the resilience of the fishing industry and coastal communities will depend on accurate information to make decisions. The natural environment is studied by oceanographers and ecologists developing a coupled atmosphere-ice-ocean-ecosystem model. This model evaluates how changes in the Arctic cryosphere and ocean circulation affect ecosystem and fishery productivity at the lower latitudes of the Northwest Atlantic. Model outputs are validated using existing field datasets, some of which are co-produced by the fishing industry. Improved predictive models resulting from this effort are used for forecasts and scenario analysis of lobster population distribution. Social systems are studied through development of a bio-economic model of the fishing fleet and evaluation of the economic reliance of the fishery. The NNA Lobster Network leads to a broadened understanding of physical, biological and socio-economic conditions at varying scales of interest under past and future climate and management scenarios.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.

NSF的10个大创意之一是导航新北极（NNA）。 NNA项目应对北极快速变化的融合科学挑战。需要进行这项北极研究，以告知国家，较大地区和全球的经济，安全和弹性。 NNA赋予从本地量表到国际规模的新研究伙伴关系，使下一代北极研究人员多样化，加强了正规和非正式教育方面的努力，并在适当的情况下整合了知识的共同生产。该奖项通过解决以下NNA焦点领域中的社会系统与自然环境之间的互动来实现这一目标：数据和观察，教育，预测，全球影响和弹性基础设施。Rapid北极变暖正在改变北大西洋的循环。导致海洋生态系统的变化可能会破坏新英格兰和加拿大大西洋沿海地区的区域渔业。这些变化将为沿海社区带来新的挑战和机会。这个NNA研究项目的重点是北极变化与标志性美国龙虾（Homarus Americanus）渔业之间的联系。龙虾渔业是北美最有价值的单物种渔业。它也是一个经过充分研究的社会生态系统，使其成为融合研究的良好主题。该项目建立了基于跨部门和跨境合作伙伴关系的NNA龙虾网络。该项目开发了一个气候脆弱性评估，重点是龙虾在温暖的海洋中的北向地理范围变化。该项目正在产生新知识，以了解气候引起的北极变化，较低纬度海洋生态系统和西北大西洋的标志性渔业之间的联系。该协作项目测试两个总体假设：（1）气候驱动的北极变化将影响美国龙虾股票的分布和丰度，以及（2）捕鱼业和沿海社区的韧性将取决于准确的信息来做出决策。海洋学家和生态学家对自然环境进行了研究，开发了耦合的气氛 - 冰山生态系统模型。该模型评估了西北大西洋较低纬度的生态系统和渔业生产力如何评估北极冰冻圈和海洋循环的变化。使用现有的现场数据集对模型输出进行了验证，其中一些是由捕鱼行业共同生产的。通过这项工作产生的改进的预测模型用于龙虾种群分布的预测和方案分析。通过开发捕鱼舰队的生物经济模型以及对渔业经济依赖的评估来研究社会系统。 NNA龙虾网络在过去和未来的气候和管理场景下，在不同范围的感兴趣的范围内，对物理，生物学和社会经济状况有了广泛的了解。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的审查标准来通过评估来通过评估来支持的。
