项目摘要

Funds are provided to establish a base program for year-round acoustic monitoring of marine mammals in Bering Strait. Instrumentation will be added onto an existing high resolution physical and biological mooring program (National Science Foundation-Arctic Observing Network (AON) and RUSsian American Long-term Census of the Arctic), also supported by annual survey data. The combination of these data sets will provide urgently required, base-line information on how species presence varies seasonally with changes in sea ice, currents, ocean water temperatures and freshwater flow. Building on opportunistic proof-of-concept deployments in the strait in the last 2 years, the proposed effort will also provide critical, consistent data on interannual variability, and allow for the testing of cutting edge scientific hypotheses such as: how do oceanographic conditions dictate the residency of different marine mammal species? Are temperate species ?invading? the Arctic? What is the correlation between ice cover and marine mammal sound production?The Bering Strait is the only oceanic connection between the Pacific and the Arctic oceans. It is through this narrow (~85 km) passageway that the entire population of Bering-Chukchi-Beaufort bowhead whales passes twice yearly and that herds of beluga whales access Arctic waters. It is thought to be year-round habitat for ice seals and walrus . The Bering Strait is also the path by which Pacific sub-Arctic marine species are invading the Arctic. As the Northwest Passage becomes a viable Pacific-Atlantic shipping route, every ship along this route will pass through Bering Strait. It is, therefore, the region where climate change and changing anthropogenic utilization may have sizeable impacts on local marine fauna, and where changing fluxes of marine mammals to the Arctic can be well observed. Passive acoustic monitoring is the only method currently available to identify year-round, and in all weather conditions, the presence of marine mammals and other physical (ice movement) or anthropogenic (ships, oil and gas seismic exploration) sounds.

提供资金，建立一个基础计划，全年声学监测的海洋哺乳动物在白令海峡。仪器将被添加到现有的高分辨率物理和生物系泊计划（国家科学基金会-北极观测网络（AON）和俄美北极长期普查），也得到年度调查数据的支持。这些数据集的结合将提供迫切需要的基线信息，说明物种的存在如何随着海冰、海流、海水温度和淡水流量的变化而季节性变化。在过去两年中在海峡进行的机会性概念验证部署的基础上，拟议的努力还将提供关于年际变化的关键，一致的数据，并允许测试尖端科学假设，例如：海洋条件如何决定不同海洋哺乳动物物种的居住地？是温带物种？入侵？北极吗冰盖与海洋哺乳动物发声之间有何相关性？白令海峡是太平洋和北冰洋之间唯一的海洋连接。整个白令-楚科奇-博福特弓头鲸种群每年两次通过这条狭窄（约85公里）的通道，白鲸群也通过这条通道进入北极沃茨。它被认为是冰海豹和海象的全年栖息地。白令海峡也是太平洋亚北极海洋物种入侵北极的途径。随着西北航道成为一条可行的太平洋-大西洋航线，这条航线上的每艘船只沿着都将通过白令海峡。因此，在该区域，气候变化和不断变化的人类利用可能对当地海洋动物产生相当大的影响，在该区域，可以很好地观察到海洋哺乳动物不断变化的北极流量。被动声学监测是目前唯一可用于全年和在所有天气条件下查明海洋哺乳动物和其他物理（冰的移动）或人为（船舶、石油和天然气地震勘探）声音的存在的方法。
