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年美国复苏和再投资法案（公法111-5）资助的。 该奖项授予阿拉斯加大学费尔班克斯（UAF），用于建造阿拉斯加地区研究船（ARRV），该船于2009年3月获得国家科学委员会的批准。 预计该船将于2013年年中交付，2014年开始进行科学作业。技术描述：242英尺长的阿拉斯加地区研究船（ARRV）将是一艘多用途研究船，将大大改善北极沃茨的使用情况，并扩大该地区目前的科学能力。 它是专门为在季节性海冰和阿拉斯加附近的公海沃茨工作而设计的;包括楚科奇海、博福特海和白令海以及北极东部。 为此，船体将根据美国船级社（ABS）的冰分类标准进行冰加固。 ARRV将提供一个急需的、技术先进的海洋学平台，使多学科团队能够在冰缘和厚达3.9英尺的季节性海冰中进行实地研究。 ARRV将具有许多先进的功能，包括下一代科学处理系统，以提高海上安全和效率，以及一套现代卫星通信，将船舶与岸上的教育设施联系起来。 其设计对自身环境的影响最小，包括用于渔业和声学研究的低水下辐射噪声（URN），以及减少烟囱排放以进行大气研究。 ARRV拥有26个专用科学泊位，每年将能够容纳500多名研究人员和学生，并在海上度过多达300天。 更广泛的影响：阿拉斯加的海岸线比48个州的海岸线加起来还要长，其专属经济区（EEZ）的面积约为美国专属经济区的三分之二。 白令海和阿拉斯加湾的鱼产量占全国年总渔获量的一半以上。北极地区是世界上最具生产力的海洋生态系统之一，也是海洋哺乳动物种群丰富多样的地区。 据估计，常年海冰每十年减少约9%，可能导致夏季无冰的北冰洋在世纪末或更早。 2008年夏天，西北航道自卫星图像拍摄以来首次开放。 沿着重大的生态系统变化和对沿海社区的影响，这种变化可能会通过提供进一步进入阿拉斯加北海岸沿着地区的定期贸易路线来影响国家安全和商业。 开放这一脆弱的地区进行商业活动将提高科学研究的重要性，以了解北极地区的影响。 例如，生物生产力的急剧变化被预测为逐渐变暖、持续的冰衰退、洋流变化、海洋酸化和气候条件变化的结果。 北极气候变化很可能是整个地球气候变化的关键驱动因素之一。 除了生物和气候变化，阿拉斯加湾和阿留申地区也受到重大地震过程的影响。 扩大我们对俯冲带和海底火山喷发历史的了解将有助于预测毁灭性海啸的潜在风险。 所有这些科学任务和活动不仅对美国，而且对整个地球仪的经济和环境福利也是如此。阿拉斯加地区研究船（ARRV）将为科学进入这些具有如此巨大的国家和国际重要性的偏远和荒凉地区提供一个安全和高效的平台。 ARRV将取代由阿拉斯加大学费尔班克斯运营的R/V阿尔法螺旋。 当该船于2006年退役时，它已经超过了预期的30年使用寿命。 ARRV将是自1980年以来NSF建造的第一艘船舶。S. 致力于建造这艘高性能船舶代表了NSF对国际极地年遗产的重大贡献，美国北极政策的推进，以及更好地了解全球问题的努力，包括气候变化和海洋环流。
