Collaborative Research: An interdisciplinary monitoring mooring in the western Arctic boundary current: Climatic forcing and ecosystem response

该奖项由2009年《美国复苏和再投资法案》（公法111-5）资助。提供的资金用于在巴罗峡谷以东的西北极边界流核心部署一个战略性定位的系泊系统，该系统将收集测量数据，以估计重要物理、化学和生物量的顺流和横流通量。这些测量将增进我们对北极西部海洋-大气-冰系统的了解，包括生态系统的关键方面，这些方面由于冰盖而在一年中的大部分时间都无法实现。对现场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位置和设计，并使他深入了解可以从这样的时间序列中获得的大量信息。使用新一代系泊剖面仪，系泊系统将提供完整的水柱轨迹（从海底附近到冰底），包括温度、盐度、溶解氧、pH值、浊度、叶绿素荧光、硝酸盐、后向散射（浮游动物的代表）和速度。此外，系泊将提供冰厚度和冰速度、底部压力和海洋哺乳动物叫声的时间序列。

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.
