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.

北极和亚北极地区发生了惊人的气候变化。对大气，海洋和淡水/冰冻圈的单独分析均显示出越来越多的水文循环，海冰撤退，加速大西洋水域的入侵，降低了亚极性盐度和过去30年中大西洋风暴的渗透率增加。意识到自然和人类诱发的气候变化倾向于集中在北部高纬度上，这是一项称为ASOF（ASOF（北极海洋流量））的国际计划。欧洲和俄罗斯的捐款被归为“ ASOF-EAST”，而美国，加拿大，格陵兰和日本的捐款被归为“ Asof-West”。这是支持ASOF-West的协调，管理和综合的一项建议。智力优点。气候研究是所有科学企业中最广泛的研究之一。它涉及海洋/大气循环的物理学，但随着时间的流逝，化学和生物学的影响以及地质学。除了这些领域之外，气候研究还涉及一系列物理学的动力学原理。而理论。气候研究并不多，它们为数值建模的不精确活性以及对许多和多样化的观察结果的解释提供了必不可少的基础。 更广泛的影响。 ASOF计划影响高纬度气候和全球气候的许多方面。我们的海洋中不断发展的变化，大气生物圈引起了核心问题，因为它们表达了地球的可居住性不断变化。拟议的工作还将为研究生的培训和教育做出贡献，以及对北极变化，全球气候以及物理和生物学世界的未来感兴趣的受众更大的受众。在这项研究中带来的新技术（新的卫星传感器，自动式海底车辆）与更大的技术素养人群社区提供了许多联系，并充当向公众传授有关气候和环境的兴趣点。
