Striking climate change is occurring in the Arctic and subArctic region. Separate analyses of atmosphere, ocean and fresh-water/cryosphere all reveal an increasing hydrologic cycle, sea- ice retreat, accelerated incursion of Atlantic waters, decreasing subpolar salinity and increased penetration of Atlantic storms over the past 30 years. Realization that both natural and human- induced climate change tend to focus on high northern latitudes, an international program known as ASOF (Arctic-SubArctic Ocean Flux) has been developed. European and Russian contributions are grouped as 'ASOF-East' while contributions from the US, Canada, Greenland and Japan are grouped as 'ASOF-West.' This is a proposal to support coordination, administration and synthesis of ASOF-West. Intellectual merit. Climate research is one of the broadest of all scientific enterprises. It involves the physics of ocean/atmosphere circulation, yet with impacts of chemistry and biology and, over time, geology. Beyond these domains, climate research involves a deep set of dynamical principles of physics. While .theoretical. climate studies are not numerous, they provide essential underpinning for the inexact activity of numerical modelling, and for the interpretation of the many and diverse observations. Broader impacts. The ASOF program impacts many aspects of high-latitude climate, and global climate. The evolving changes in our ocean, atmosphere biosphere are of central concern, because they express the changing habitability of Earth. The proposed work will also contribute to the training and education of graduate students, and of a much larger audience interested in Arctic change, global climate, and the future of the physical and biological world. New technologies being brought to bear in this research (new satellite sensors, autonomous undersea vehicles) provide many connections with the larger community of technically literate people, and act as a point of interest for teaching the public about climate and environment.

北极和亚北极地区正在发生惊人的气候变化。对大气、海洋和淡水/冰冻圈的单独分析都表明，在过去30年里，水文循环增加，海冰退缩，大西洋水域加速入侵，亚极地盐度降低，大西洋风暴的渗透增加。认识到自然和人为引起的气候变化都倾向于集中在北纬高纬度地区，一个被称为北极-亚北极海洋通量（ASOF）的国际项目已经发展起来。欧洲和俄罗斯的贡献被归类为“ASOF-East”，而美国、加拿大、格陵兰岛和日本的贡献被归类为“ASOF-West”。这是一个支持ASOF-West协调、管理和综合的建议。知识价值。气候研究是所有科学事业中最广泛的一项。它涉及海洋/大气环流的物理学，但也有化学和生物学的影响，随着时间的推移，还有地质学的影响。除了这些领域之外，气候研究还涉及一套深入的物理动力学原理。而.theoretical。气候研究并不多，它们为数值模拟的不精确活动和对许多不同观测的解释提供了必要的基础。更广泛的影响。ASOF项目影响了高纬度气候和全球气候的许多方面。海洋、大气、生物圈的不断变化是我们关注的焦点，因为它们反映了地球可居住性的变化。拟议的工作还将有助于研究生的培训和教育，以及对北极变化、全球气候以及物理和生物世界的未来感兴趣的更多受众。在这项研究中使用的新技术（新的卫星传感器，自主水下航行器）提供了许多与更大的技术素养人群社区的联系，并作为向公众传授气候和环境知识的兴趣点。
