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 WHITLEDGETHIS建议要求支持边缘冰区（MIZ）研究船的设计和模型测试的第二阶段。 UNOLS已建立和审查了科学任务要求，并于2000年秋季开始。拟议的船只将取代当前的UNOLS区域研究船R/V Alpha Helix，R/V Alpha Helix，功能强大，多功能且更大的运输且更大的运输量更大，能够更好地满足各种用户的需求。北到丘奇和博福特海。 这个广阔的地区占美国大陆架及其唯一的北极水域的大部分。 这里可以找到世界上一些最有生产力的渔业，并且对支持这些人群的海洋生态系统的研究有很强的需求。 海洋哺乳动物和鸟类研究正在增加，并且由于“需要知道”的管理和法律目的，可能会增加更多。 土著人民沿着海岸生活，并利用海洋资源来维持生计。 这些考虑因素的一部分是由白令海和阿拉斯加北部北部的研究的支持。 很少了解海洋和大气条件中的主要年代际变化和年际变异性，或者高纬度海洋系统在全球气候过程中的作用。 结果，该地区对船舶支援的需求不断增加，今年R/V Alpha Helix提供了最大的海天数量，因为她的大小，能力和季节性限制受到挑战性的亚北极条件施加的季节性限制。 预计随着功能更强大的血管，这种需求将增加。
