Collaborative Proposal: 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)提供资金，用于在巴罗峡谷以东的北极西部边界流的核心地带部署一个战略性的单一系泊设施，该设施将收集测量数据，以估计重要的物理、化学和生物量的顺流和横流通量。这些测量将加强我们对北极西部海洋-大气-冰系统的了解，包括由于冰盖而全年大部分时间无法获得的生态系统的关键方面。对现场以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，系泊设备将提供温度、盐度、溶解氧、pH、浊度、叶绿素荧光、硝酸盐、后向散射(浮游动物的替代指标)和速度的全水柱痕迹(从海底附近到冰底)。此外，系泊设备将提供冰层厚度和冰层速度、海底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.
