This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The award is made to the University of Alaska Fairbanks (UAF) for the construction of the Alaska Region Research Vessel (ARRV) based on the approval to proceed received from the National Science Board in March 2009. Delivery of the vessel is anticipated in mid-2013 with science operations beginning in 2014.Technical Description: The 242-foot Alaska Region Research Vessel (ARRV) will be a multipurpose research ship that will dramatically improve access to Arctic waters and expand current scientific capabilities in the region. It is designed specifically to operate in seasonal sea ice and open ocean waters near Alaska; including the Chukchi, Beaufort, and Bering Seas as well as the eastern Arctic. To do so, the hull will be ice-strengthened to American Bureau of Shipping (ABS) ice classification standards. The ARRV will provide a much needed, technologically-advanced oceanographic platform to enable multidisciplinary teams to conduct field research at the ice edge and in seasonal sea ice up to 3.9 feet thick. The ARRV will have many advanced capabilities including next-generation science handling systems to improve safety and efficiency at sea, and a modern suite of satellite communications to link the ship to educational facilities ashore. It is designed to have a minimal influence on its own environment, including low underwater radiated noise (URN) for fisheries and acoustics research, and reduced stack emissions to enable atmospheric research. With twenty six dedicated science berths, the ARRV will be able to accommodate over 500 researchers and students annually and spend as many as 300 days at sea. The anticipated operational lifetime of the ARRV is at least 30 years.Broader Impacts: The Alaska coastline is longer than that of the contiguous forty eight states combined, and the area of its Exclusive Economic Zone (EEZ) is approximately two thirds of the total US EEZ. The Bering Sea and Gulf of Alaska sustain more than half of the total annual national fish catch. The area supports one of the most productive marine ecosystems in the world, as well as rich and varied marine mammal populations.The Arctic region is changing rapidly. Perennial sea ice has been estimated to be decreasing by about 9% per decade, potentially leading to a summer ice-free Arctic Ocean by the end of the century or even sooner. In the summer of 2008 the Northwest Passage was open for the first time since satellite imagery has been taken. Along with the significant ecosystem changes and impact on coastal communities, this change could impact national security and commerce by providing regular trade routes further into regions along the north coast of Alaska. Opening this fragile area to commerce will heighten the importance of scientific research to understand the effects.Scientific interest in the Arctic region is intensive and highly varied. For example, dramatic changes in biological productivity have been predicted as a consequence of progressive warming, continuing ice recession, changing ocean currents, ocean acidification, and varying climatic conditions. Changing Arctic climate may well be one of the critical drivers for climate change over the entire planet. Besides biological and climatological changes, the Gulf of Alaska and Aleutian areas are also subject to major seismic processes. Extending our knowledge about subduction zones and the eruptive history of seafloor volcanoes would help predict the potential risk for devastating tsunamis. All of these scientific missions and activities are of continuing interest and great importance not only to the U.S., but also to the economic and environmental welfare of the entire globe.The Alaska Region Research Vessel (ARRV) will provide a safe and highly effective platform for scientific access to these remote and inhospitable areas that are of such great national and international importance. The ARRV will replace the R/V ALPHA HELIX which was operated by the University of Alaska, Fairbanks. When the vessel was retired from service in 2006 it was well past its expected 30-year service life. The ARRV will be the first NSF-built ship since the 1980?s. Committing to construction of this highly capable vessel represents a major NSF contribution to the International Polar Year legacy, advancement of US Arctic Policy, as well as the effort to better understand global issues, including climate change and ocean circulation.

该奖项是根据2009年《美国复苏与再投资法》（公法111-5）资助的。 该奖项是根据2009年3月从国家科学委员会收到的批准从国家科学委员会收到的批准来授予阿拉斯加地区研究船（ARRV）的建造阿拉斯加地区研究船（ARRV）的奖项。预计该船的交付将于2013年6月中旬开始，从2014年中期开始进行科学运营。水和扩大该地区当前的科学能力。 它专门设计用于在阿拉斯加附近的季节性海冰和开放海水中运作；包括Chukchi，Beaufort和Bering海以及东北极。 为此，船体将加强到美国航运局（ABS）冰分类标准。 ARRV将提供一个急需的技术知识海洋学平台，以使多学科团队能够在冰边和季节性海冰进行现场研究，最高3.9英尺。 ARRV将具有许多高级功能，包括下一代科学处理系统，以提高海上的安全性和效率，以及一套现代的卫星通信套件，以将船与岸上的教育设施联系起来。 它旨在对自己自身的环境产生最小的影响，包括用于渔业和声学研究的水下辐射噪声（URN），以及减少堆栈排放以实现大气研究。 ARRV拥有26个专门的科学席位，每年能够容纳500多名研究人员和学生，并在海上花费多达300天。 ARRV的预期运营寿命至少为30年。公民的影响：阿拉斯加海岸线的长度比连续的四十八个州合并的时间更长，其独家经济区（EEZ）的面积约为美国EEZ总数的三分之二。 阿拉斯加的白令海和海湾维持了年度全国鱼类捕捞量的一半以上。该地区支持世界上最有生产力的海洋生态系统之一，以及丰富和多样化的海洋哺乳动物人群。北极地区正在迅速变化。 据估计，多年生海冰每十年减少约9％，可能导致夏季无冰的北极海洋到本世纪末，甚至更快。 自摄取卫星图像以来，2008年夏天，西北航道首次开放。 随着生态系统的重大变化和对沿海社区的影响，这种变化可能会通过将定期贸易路线进一步提供到阿拉斯加北部海岸的地区来影响国家安全和商业。 向商业开放这个脆弱的领域将增强科学研究对理解效果的重要性。北极地区的传统兴趣是密集的，并且高度多样。 例如，由于进行性变暖，持续的冰衰退，洋流，海洋酸化和变化的气候条件，已经预测了生物生产力的巨大变化。 北极气候变化很可能是整个星球中气候变化的关键驱动因素之一。 除了生物学和气候变化外，阿拉斯加和阿留申地区的海湾还需要进行主要的地震过程。 扩展我们对俯冲带和海底火山的爆发历史的了解将有助于预测毁灭性海啸的潜在风险。 所有这些科学的任务和活动不仅对美国，而且对整个世界的经济和环境福利都具有持续的兴趣和重要性。阿拉斯加地区研究船（ARRV）将为对这些偏远和无所不能的地区的科学访问提供一个安全而高效的平台，这些平台具有如此重要的国家和国际重要性。 ARRV将替换由阿拉斯加大学Fairbanks经营的R/V Alpha螺旋。 当该船于2006年退休时，它已经超过了预期的30年使用寿命。 自1980年以来，ARRV将是NSF建造的第一艘船。 致力于建设这款高功能强大的船只代表了NSF对国际极地遗产，美国北极政策的发展以及更好地了解全球问题的努力，包括气候变化和海洋流通的努力。
