A Planning Workshop for an International Coupled North Atlantic-Arctic Science Program

耦合的北大西洋和北冰洋盆地以及相关的区域大陆架和边缘海是全球气候、生物和生物地球化学系统的一个组成部分。它是暖流与北极寒流交汇的场所，也是经向翻转环流（AMOC）的北臂和深水形成的场所，在全球气候和热量再分布中起着重要作用。这片广阔的区域为地球上一些最大的鱼类资源提供了栖息地。此外，仅北大西洋就吸收了每年大约四分之一的人为二氧化碳排放量。在全球气候变化加速的时刻，对北美和欧洲各国政府和科学家来说，共同努力促进我们对该地区与全球气候变化之间联系的机制理解尤为重要。伍兹霍尔海洋研究所的美国海洋碳和生物地球化学项目办公室将利用这笔资金，与欧盟委员会和加拿大合作，协调并举办一个科学研讨会，为北大西洋-北极研究项目制定一个全面的愿景。研讨会将汇集海洋生态系统动力学、海洋生物地球化学和海洋物理学方面的必要专业知识，为一项大型国际研究计划建立跨学科框架，以研究北大西洋-北极系统的关键组成部分（AMOC，春季开花时间和动力学等）。虽然以前在该地区的观测活动提供了巨大的见解，但这项努力将是对协调研究计划的长期投资，以使生物地球化学和生态系统过程与海洋物理学一起研究，这将是获得北大西洋-北极系统如何运作及其变化的更完整图景所必需的。潜在的项目主题可能包括两个流域之间的交流、小尺度（中尺度和亚中尺度）和大尺度（AMOC）环流、春季水华动态、可持续渔业、生态系统健康和预测建模。更广泛的影响：本次研讨会以及由此产生的国际研究倡议体现了解决直接影响人类的重要科学问题所需要的全球科学事业类型。智力和资金资源的国际汇集不仅提高了科学的质量，而且还防止了重复工作和资源浪费，促进了跨越多学科和地理边界的协作方法和全面愿景。这一努力的时机至关重要，因为主要的国际参与者已经准备好推进科学规划工作，并为国际研究项目投入资源。

The coupled North Atlantic and Arctic Ocean basins and the associated regional shelves and marginal seas are an integral part of the global climatic, biological, and biogeochemical system. As the locus of confluence of the warm Gulf Stream and cold Arctic waters and the northern arm of meridional overturn circulation (AMOC) and deep-water formation, it is a major player in global climate and heat redistribution. This extensive region provides habitat supporting some of the largest exploited fish stocks on Earth. Moreover, the North Atlantic alone sequesters approximately one-quarter of the annual anthropogenic carbon dioxide production. At a time of accelerating global climate change, it is especially important for North American and European governments and scientists to work jointly to advance our mechanistic understanding of the links between this region and global climate change.With funds from this award, the U.S. Ocean Carbon and Biogeochemistry Program Office at the Woods Hole Oceanographic Institution will join with the European Commission and Canada to coordinate and run a scientific workshop to develop a comprehensive vision for a North Atlantic - Arctic research program. The workshop will bring together the necessary expertise in marine ecosystem dynamics, marine biogeochemistry, and ocean physics to establish the interdisciplinary framework for a large international research initiative to examine key components of the North Atlantic - Arctic system (AMOC, spring bloom timing and dynamics, etc.). While previous observational campaigns in the region have provided tremendous insights, this effort would be a long-term investment in a coordinated research program to enable the study of biogeochemical and ecosystem processes alongside ocean physics that will be required for obtaining a more complete picture of how the North Atlantic - Arctic system works and how it is changing. Potential program themes might include (among other things) communication between the two basins, small-scale (mesoscale and submesoscale) and large-scale (AMOC) circulation, spring bloom dynamics, sustainable fisheries, ecosystem health, and predictive modeling.Broader Impacts: This workshop and the international research initiative that will emerge from it embody the type of global scientific enterprise that is needed to address important science questions that directly impact humans. International pooling of intellectual and monetary resources not only improves the quality of the science, but it prevents duplication of effort and wasted resources, and promotes a collaborative approach and a comprehensive vision that spans multiple disciplinary and geographic boundaries. The timing of this effort is critical, since key international players are ready to move forward with scientific planning efforts and commit resources to an internationalresearch program.
