项目摘要
The Arctic is changing. The Distributed Biological Observatory studies these changes in the northern Bering and Chukchi seas. Investigators sample locations that are biologically important in U.S. territorial waters. These locations have been sampled annually since 2010. Other investigators also sample the same locations. As a result, the locations are sampled multiple times a year. Data are collected on environmental conditions including water column and sea floor animals that are food for whales, seals, and birds. Data are shared internationally. The project contributes to the U.S. National Ocean Policy and Interagency Arctic Research Policy Committee 5-year plan. The data will be of value to U.S. and international science and management agencies, private industry, and local communities as they try to understand changes to the environment. The project supports three graduate students.The observational plan includes standard hydrographic and biological measurements along five transect lines located in the northern Bering and Chukchi Seas. These sampling locations are arrayed south-to-north and reflect a gradient of seasonal sea ice change and seawater warming. The investigators chose these 5 regions because they are zones of high biological productivity and biodiversity. Results so far indicate a freshening and warming of Pacific seawater which transits northward over the spring to fall season. These changes have impacted prey for larger marine mammals and seabirds. Satellite observations are also used to evaluate seasonal changes in sea ice concentration, surface seawater temperature, and chlorophyll concentration. The biological measurements focus on lower trophic levels and shipboard surveys of upper trophic level organisms. This research will increase our understanding of the impact of key environmental forcing parameters on biological change in the system. The collection of key prey-predator biological data along with physical and chemical measurements will allow for analyses and ecosystem modeling which will promote better understanding of Arctic environmental changes.
北极正在发生变化。分布式生物观测站研究了白令海北部和楚科奇海的这些变化。调查人员对美国领海中具有重要生物学意义的地点进行了取样。自2010年以来,每年对这些地点进行采样。其他调查人员也在同样的地点取样。因此,每年对这些地点进行多次采样。收集环境状况的数据,包括作为鲸鱼、海豹和鸟类食物的水柱和海底动物。数据在国际上共享。该项目为美国国家海洋政策和机构间北极研究政策委员会的五年计划做出了贡献。这些数据对于试图了解环境变化的美国和国际科学和管理机构、私营企业和当地社区都很有价值。该项目资助了三名研究生。观测计划包括沿白令海北部和楚科奇海的五条样线进行标准的水文和生物测量。这些采样点从南到北排列,反映了季节性海冰变化和海水变暖的梯度。研究者选择这5个区域是因为它们是生物生产力和生物多样性高的区域。到目前为止的结果表明,太平洋海水在春季到秋季向北流动,海水变暖变新鲜。这些变化影响了大型海洋哺乳动物和海鸟的猎物。卫星观测还用于评估海冰浓度、海水表面温度和叶绿素浓度的季节变化。生物测量侧重于低营养水平和船上调查的高营养水平的生物。这项研究将增加我们对系统中关键环境强迫参数对生物变化的影响的理解。收集关键的捕食生物数据以及物理和化学测量数据将有助于进行分析和建立生态系统模型,这将促进对北极环境变化的更好理解。
