9812638 Terray This Small Grants for Exploratory Research (SGER) project involves a feasibility study of making measurements of currents in a seafloor hydrothermal vent field using a downward-looking, broadband acoustic Doppler current profiler (ADCP) mounted on the JASON remotely-operated vehicle. The ADCP will map the large scale currents with respect to the physical structure of the vent field. Such measurements can be used in conjunction with thermistor moorings to estimate the advective heat flux. Another objective is to develop a rough index of fluid temperature based on the ping-to-ping correlation of the Doppler return. If successful, this work will add an important hydrodynamic measurement to the techniques needed to characterize the heat output of vent fields.

9812638 Terray这个小型探索性研究赠款项目涉及一项可行性研究，即使用安装在JASON遥控飞行器上的向下俯视的宽带声学多普勒海流剖面仪测量海底热液喷口区域的洋流。ADCP将绘制与喷口区域物理结构相关的大尺度洋流图。这样的测量可以与热敏电阻系泊一起使用，以估计平流热流。另一个目标是开发一个基于多普勒回波的ping-to-ping相关性的流体温度的粗略指数。如果成功，这项工作将为表征喷口区域热输出所需的技术增加一项重要的流体力学测量。
