Navigating the New Arctic (NNA) is one of NSF's 10 Big Ideas. NNA projects address convergence scientific challenges in the rapidly changing Arctic. The 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 between social systems and natural environment in the following NNA focus areas: Arctic residents, Data and Observation, Global Impact, and Resilient Infrastructure. Atlantic cod has been an important resource for coastal and inland communities throughout the Atlantic world for at least 1000 years. This humble fish played an important role in feeding communities, developing markets, and facilitating trade and continues to be a vitally important species. Management decisions made about existing cod populations are based on scientist’s ideas of what a baseline ‘normal’ or ‘natural’ cod population is. This ‘baseline’ for cod is mostly based on data from the last 100-150 years, including how large cod populations have been, how large the fish have been, how old, etc. On top of this are ideas of how these fish respond to changing human and environmental conditions. A variety of techniques from marine biology, archaeology, and history now allow us to track changing marine ecological conditions as well as relative population size over the last millennium. By creating a deeper record of cod populations over the last millennium, this project contributes vital data that will improve understanding of the cod fisheries as they reacted to climate, political and economic change in the past and how the Icelandic fishing communities of today can adapt and remain resilient as the fishery changes with warming Atlantic waters and new political and economic drivers. The project uniquely involves international and transdisciplinary research between the natural environment and social systems including archaeology, ecology, history, fisheries and oceanography. The knowledge gained from the project is beneficial to our planning strategy to deal with impacts of environmental change on American fisheries and the people who depend on them. The new interdisciplinary methodology also provides novel opportunities for educating university students. The project will use bones from cod as well as other coastal species that have been excavated from archaeological sites in Iceland and the Faroes over the last 30 years. These sites were lived in from the 9th to the 19th centuries. These bones will be the subject of a variety of biochemical analyses that allow us to track population size, body length, and feeding changes over the last millennia. These analyses will be combined with archaeological and historical methods to build a new and deeper record of the relationship between cod, humans, and the environment that will serve as an important tool in managing this relationship in the present and future.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焦点领域的社会系统与自然环境之间的互动来实现该目标的一部分：北极居民，数据和观察，全球影响以及弹性基础设施。至少有1000年，大西洋鳕鱼一直是整个大西洋世界的沿海和内陆社区的重要资源。这种不起眼的鱼在喂养社区，发展市场和支持贸易方面发挥了重要作用，并继续成为一个至关重要的物种。对现有鳕鱼种群做出的管理决定是基于科学家对基线“正常”或“自然”鳕鱼种群的想法的。这种鳕鱼的“基线”主要基于过去100 - 150年来的数据，包括鳕鱼种群的大小，鱼的大小，多大年龄等。此外，这些鱼类如何应对人类和环境状况的改变。现在，从海洋生物学，考古学和历史上进行了各种技术，现在使我们能够跟踪上千年中不断变化的海洋生态条件以及相对人口的规模。通过在过去的千年中创建更深入的鳕鱼种群记录，该项目贡献了重要数据，这将在过去对过去的气候，政治和经济变化做出反应以及当今的冰岛渔业社区的反应时，可以提高对鳕鱼渔业的理解，以及当今的冰岛渔业社区如何适应并保持依赖，因为随着渔业的变化而随着温暖的大西洋大道沃特斯（Atlantic Atlantic Waters）以及新的政治驱动力的变化而变化。该项目独特地涉及自然环境和社会系统之间的国际和跨学科研究，包括建筑，生态，历史，渔业和海洋学。从项目中获得的知识对我们的计划策略有益于应对环境变化对美国渔业和依赖人民的影响。他们。新的跨学科方法还为教育大学生提供了新的机会。该项目将使用COD以及其他沿海物种的骨头，这些骨骼已从冰岛的存档地点和Faroes挖掘出来。这些地点居住在9世纪至19世纪。这些骨骼将成为各种生化分析的主题，这些分析使我们能够跟踪过去几千年中人口规模，体长和进食变化。这些分析将与档案和历史方法相结合，以建立鳕鱼，人类和环境之间关系的新的，更深入的记录，这将是在当前和未来中管理这种关系的重要工具。这项奖项反映了NSF的法定任务，并通过使用该基金会的知识分子功能和广泛的影响来评估NSF的法定任务，并被认为是珍贵的支持。
