The Arctic Ocean ecosystem may respond dramatically to climate change through already observed modification of the physical environment (e.g., hydrography and ice cover). A better understanding of the coupled biological-physical ocean ecosystem, and its interannual variability, is necessary to predict and understand these potential impacts of climate change on the Arctic ecosystem. The Chukchi-Beaufort Sea region near Barrow, AK, including coastal waters, has been identified as key because it lies at the junction of several ocean regions and downstream of the Pacific Arctic gateway and hence is influenced physically and ecologically by input from Bering Strait. Researchers have conducted oceanographic sampling of the coupled physical and biological marine environment in the Chukchi and near-shore Beaufort Seas for five years (2005 ? 2009), including coastal waters, using boat-based surveys during late summer and short-term (month) and year-long bottom-mounted moorings, and have observed significant interannual variability. They will now establish annual surveys of the pelagic marine environment and deploy a year-round mooring in Barrow Canyon as components of the Arctic Observing Network (AON). The surveys will measure a range of biological and physical parameters including hydrography, currents, plankton standing stocks, nutrients, and plankton genetics. The mooring will measure ocean currents, near bottom temperature and salinity, and acoustic backscatter (zooplankton proxy) in Barrow Canyon at a location typically within or beneath the Alaska Coastal Current.Results from this AON component will provide a 10-year record and enable a better understanding of inter-annual variability in the physical and biological characteristics of the Barrow area ocean confluence. Based on these data, changes in biological characteristics that respond to larger climate change can be detected. This proposed AON component includes measurements of key oceanic biological and chemical parameters, and their coupling to physical parameters from a region sensitive to climate change. The researchers will actively communicate plans and results with the community of Barrow through formal and informal discussions and presentations. They will also support the participation of a teacher in fieldwork for two of the years.

北极海洋生态系统可能会通过已经观察到的物理环境（例如水文和冰覆盖）来对气候变化做出巨大反应。对耦合生物物理海洋生态系统及其年际变异性的更好理解对于预测和理解气候变化对北极生态系统的这些潜在影响是必要的。包括沿海水域在内的AK Barrow附近的Chukchi-Beaufort Sea地区已被确定为关键，因为它位于多个海洋地区和太平洋北极门户的下游的交界处，因此受生存海峡的输入受到物理和生态的影响。研究人员已经对Chukchi和近岸Beaufort海域的耦合物理和生物海洋环境进行了海洋学抽样五年（2005年？2009年），包括沿海水域，使用夏季和短期（月末）和一年的底部底部和底部的Moorings进行船基调查，并经过严重的间歇性可变性。现在，他们将对上层海洋环境进行年度调查，并在巴罗峡谷（Barrow Canyon）进行全年系列，作为北极观测网络（AON）的组成部分。这些调查将测量一系列生物学和物理参数，包括水文学，电流，浮游生物储备，养分和浮游生物遗传学。系泊将在巴罗峡谷（Barrow Canyon）的声学反向散射（浮游动物代理）接近，通常在阿拉斯加沿海电流内部或之下。基于这些数据，可以检测到对更大气候变化反应的生物学特征的变化。该提出的AON组件包括测量关键的海洋生物学和化学参数，以及它们与从敏感气候变化的区域敏感的物理参数的耦合。研究人员将通过正式和非正式的讨论和演讲来积极地与巴罗社区进行计划和结果。他们还将支持两年的老师参与实地调查。
