项目摘要

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Funds are provided to deploy a single, strategically placed mooring in the core of the western Arctic boundary current east of Barrow Canyon, which will collect measurements permitting estimation of both the alongstream and cross-stream fluxes of important physical, chemical, and biological quantities. These measurements will enhance our understanding of the western Arctic ocean-atmosphere-ice system, including crucial aspects of the ecosystem that are unattainable throughout most of the year due to ice cover. Analysis of a previously deployed high-resolution mooring array at the site has enabled the PI to determine the optimal placement and design of the mooring, and has given him insights into the vast amount of information that can be obtained from such a time-series. Using new generation moored profilers, the mooring will provide full-water column traces (from near the seafloor to the underside of the ice) of temperature, salinity, dissolved oxygen, pH, turbidity, chlorophyll fluorescence, nitrate, backscatter (a proxy for zooplankton) and velocity. In addition, the mooring will provide time-series of ice thickness and ice velocity, bottom pressure, and marine mammal calls.

该奖项是根据2009年的《美国回收和再投资法》（公法111-5）进行资助的。提供的资金是为了在Barrow Canyon以东的西方北极边界电流的核心部署单一的策略性放置系泊设备，该港口将收集允许估算重要物理，化学，化学物质和化学物质和生物学量的测量值。这些测量结果将增强我们对西方北极海洋大气冰系统的理解，包括由于冰盖而在一年中大部分时间无法实现的生态系统的关键方面。对现场的先前部署的高分辨率系泊阵列的分析使PI能够确定系泊的最佳放置和设计，并使他对可以从此类时间序列获得的大量信息进行了见解。使用新一代系泊探测员，系泊将提供温度，盐度，盐度，溶解的氧，pH，浊度，浊度，硝酸盐，硝酸盐，硝酸盐，后散射（浮游生物的代理）和速度的温度，盐度，溶解氧，pH，浊度，浊度）和速度。此外，系泊将提供冰厚度和冰速度，底压和海洋哺乳动物呼叫的时间序列。
