OCE - 0121144WhitledgeThis proposal requests support for the second phase of the design and model testing of a Marginal Ice Zone (MIZ) Research Vessel. The Science Mission Requirements have been established and reviewed by UNOLS, and the concept design was started in the fall of 2000. The proposed vessel will replace the current UNOLS regional research vessel, the R/V Alpha Helix, with a more capable, multi-purpose and somewhat larger ship, better able to address the contemporary research support needs of a variety of users.The waters surrounding Alaska Stretch from the southeastern Alaskan fjords, to the Bering Sea and north to the Chukchi and Beaufort Seas. This vast region accounts for the majority of the United States continental shelf and its only Arctic waters. Some of the most productive fisheries in the world are found here, and there is strong demand for research on the marine ecosystems that support these populations. Marine mammal and bird research is increasing, and is likely to increase even more due to the "need to know" for management and legal purposes. Indigenous people live along the coasts, and use marine resources for subsistence. Increasing support for research in the Bering Sea and northern Gulf of Alaska, is, in part, driven by these considerations. Little is understood of major decadal and interannual variability in oceanographic and atmospheric conditions or the role of high latitude marine systems in global climatic processes. As a result, there is increasing demand for ship support in the region, and this year the R/V Alpha Helix is providing the maximum number of sea days possible, given her size, capabilities and seasonal restrictions imposed by the challenging subarctic conditions. This demand is expected to increase with a more capable vessel.

OCE -0121144 Whitledge本建议书要求支持边缘冰区（MIZ）研究船设计和模型试验的第二阶段。 科学使命要求已由联合国后勤处确定和审查，概念设计已于2000年秋季开始。 拟议中的船只将取代目前的联合国后勤事务处区域研究船R/V Alpha Hessel，用一艘能力更强、多用途和更大的船只，更好地满足各种用户的当代研究支助需要。阿拉斯加周围的沃茨从阿拉斯加东南部的峡湾延伸到白令海，向北延伸到楚科奇海和博福特海。 这一广阔区域占美国大陆架的大部分，也是美国唯一的北极沃茨。 世界上一些最具生产力的渔业在这里被发现，对支持这些种群的海洋生态系统的研究有着强烈的需求。 海洋哺乳动物和鸟类研究正在增加，而且由于出于管理和法律的目的“需要了解”，研究可能会增加得更多。 土著居民沿着海岸生活，利用海洋资源维持生计。 对白令海和阿拉斯加湾北方研究的支持不断增加，部分原因是出于这些考虑。 人们对海洋和大气条件的主要十年和年际变化或高纬度海洋系统在全球气候过程中的作用知之甚少。 因此，该地区对船舶支持的需求不断增加，今年，考虑到其规模，能力和具有挑战性的亚北极条件所带来的季节性限制，R/V Alpha Hessel正在提供尽可能多的海上天数。 预计这一需求将随着能力更强的船只而增加。
