项目摘要

Woodgate - 0632154Weingartner - 0631713Funds are provided for an observationally focused study of the entire Bering Strait region (in collaboration with Russian, Canadian and Japanese scientists). The study will include deployment of a high resolution mooring array from 2007-2009, covering the two channels of the strait and one "climate" site to the north of the strait, annual CTD surveys and mooring servicing, satellite data analysis and theoretical and modeling efforts. Science objectives are:1) to measure the velocities and water properties of the Bering Strait throughflow;2) to understand the physical processes influencing the properties of the Bering Strait throughflow, with special focus on mechanisms driving change, and consequent impacts on the Arctic Ocean;3) to quantify oceanic fluxes of volume, freshwater, heat, nutrients and chlorophyll biomass through the strait;4) to design an optimum monitoring system for oceanic fluxes through the Bering Strait.The PIs' hypotheses are that Bering Strait throughflow properties are set by global and regional oceanic and atmospheric processes, which are vulnerable to climate change, and that understanding the physical processes and scalings in the strait are key to quantifying current conditions, assessing future change scenarios, and designing an efficient observational scheme for this oceanic gateway.

Woodgate -0632154WeingArtner -0631713Funds提供了对整个白令海峡地区（与俄罗斯，加拿大和日本科学家的合作）的观察性研究。该研究将包括从2007年至2009年间部署高分辨率系泊阵列，涵盖海峡的两个渠道以及海峡北部的一个“气候”地点，年度CTD调查以及系泊服务，卫星数据分析以及理论和建模工作。科学目标是：1）测量白令海峡渗透的速度和水性质； 2）了解影响白令海峡遍及流量的影响的物理过程，特别关注驱动变化的机制，以及对北极海洋的影响； 3）; 3）以量化体积，热量，营养和毒液的海洋范围，量化量，植物效率，植物效率为4次，并量化。 PIS的假设是，全球和区域海洋和大气过程都设置了白菜海峡的假设，这些特性容易受到气候变化的影响，并且了解海峡中的物理过程和规模是量化当前条件的关键，从而对当前条件进行了量化，从而评估了未来的变化场景，并为这一有效的观察方案评估了这一远洋的境界。
