SGER: Acoustical Fingerprinting of Shallow-water, Low-Power, Mid-Frequency Seismic Reflection Systems

0631584 Gontz这项授予波士顿马萨诸塞大学的小额探索性研究补助金为从Gerry E Studds Stellwagen Bank国家海洋保护区(SBNMS)获取和分析声学数据提供支持。数据将使用NOAA国家海洋保护区计划部署的现有水听器阵列收集。SBNMS的研究协调员和一名博士后学者海洋噪声专家是该项目的联合首席调查员，NOAA国家海洋服务局提供该船进行实地工作。该项目包括在接收器的不同距离记录两种类型的地球物理声源--“轰鸣器”和“火花”。当声源不工作，但船只正在移动时，也将进行录音，以应对船舶噪音，以及当没有船只在附近时，记录各种天气条件下的背景环境声级。更广泛的影响：这里提供的支持预计将提供一组宝贵的人类和自然声音的记录，在Stellwagen Bank的浅海环境中，以评估此类声音对海洋动物和生境的潜在影响。

0631584Gontz This Small Grants for Exploratory Research award to University of Massachusetts Boston provides support for acquisition and analysis of acoustical data from the Gerry E Studds Stellwagen Bank National Marine Sanctuary (SBNMS). Data will be collected using an existing array of hydrophones deployed by the NOAA National Marine Sanctuaries Program. The Research Coordinator and a post-doctoral scholar ocean noise specialist at SBNMS are co-Principal Investigators of this project, and NOAA's National Ocean Service is providing the vessel to carry out the field effort. The project includes recording two types of geophysical sound sources, a "boomer' and a 'sparker,' at different ranges from the receivers. Recording will also be made when the sound sources are not operating, but the vessel is moving, to address ship noise, and when no vessels are in the vicinity, to record background environmental sound levels in various weather conditions. Broader Impacts: Support provided here is expected to provide a valuable set of recordings of anthropogenic and natural sounds in the shallow marine environment of Stellwagen Bank to assess potential impacts of such sounds on marine animals and habitats.***
