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

这是麻省大学波士顿分校的探索性研究小额赠款，为Gerry E Studds Stellwagen Bank国家海洋保护区（SBNMS）的声学数据采集和分析提供支持。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来收集。SBNMS的研究协调员和博士后学者海洋噪声专家是该项目的共同首席调查员，美国国家海洋和大气管理局的国家海洋局提供船只进行实地工作。该项目包括记录两种类型的地球物理声源，一种是“婴儿潮”，另一种是“火花”，它们与接收器的距离不同。在声源不工作，但船舶移动时，也会进行录音，以解决船舶噪音问题，在附近没有船舶的情况下，记录各种天气条件下的背景环境声音水平。更广泛的影响：这里提供的支持预计将提供一套宝贵的Stellwagen Bank浅海环境中人为和自然声音的录音，以评估这些声音对海洋动物和栖息地的潜在影响。***

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.***
