Reciprocal Acoustic Scintillation Instrumentation for monitoring hydrothermal plume dynamics at the Main Endeavour vent Field cabled observatory

PI要求提供资金，以开发和实施一种新型的前向散射互易声闪烁仪器，以测量路径平均的热液喷口流量(水平和垂直)以及沿声路径的温度(平均和湍流特性)。该仪器将能够在两个深度相互发送和接收来自两对收发信机的声波信号，以测量水平流动的平均和湍流特性以及沿声波路径的声速(温度)。特别是，通过相互作用的声波路径测量温度将提供从喷口发出的热通量的直接测量，并量化悬浮颗粒和湍流对测量的影响。广泛的影响：热液喷口在科学上很有趣。热液喷口也吸引了更广泛的公众，因此可以作为吸引高中生和本科生参加STEM活动的宝贵工具。PI已经证明了她能够让高中老师和学生参与她的活动。

The PI requests funding to develop and implement a novel forward scatter reciprocal acoustic scintillation instrument to measure path-averaged hydrothermal vent flow (horizontal and vertical), and temperature along the acoustic path (mean and turbulence properties). The instrument will be capable of reciprocal transmission and reception of acoustic signals from two pairs of transceivers at two depths to measure the mean and turbulent properties of the horizontal flow and sound speed (temperature) along the acoustic path. In particular, the measurement of temperature by reciprocal acoustic paths will provide a direct measure of heat flux issuing from the vents and quantify the effect of suspended particles and turbulence on their measurements.Broader Impacts: Hydrothermal vents are scientifically interesting. Hydrothermal vents also appeal to the broader public and hence can serve as a valuable vehicle to attract high school and undergraduate students to STEM activities. The PI has already demonstrated evidence that she has been able to involve high school teachers and students in her activities.
