Heat Flow Measurement from Diffuse Hydrothermal Vent Fields

在喷口场尺度上，洋脊脊漫漫性热液喷口的总热量和流体输出是未知的。同样，它在时间上的可变性也没有被测量过。研究人员已经制定了一个流体动力学模型来指导测量。该模型目前正在他们的实验室进行研究。该模型将用于指导设计，并解释从传感器阵列的结果，以监测弥漫性热液流。测量将使用经过验证的深海仪器；底栖声应力传感器（BASS）；还有热敏电阻系泊。这种传感器阵列将导致一种长期监测整个漫漫性热液场活动的技术。与已经开发的监测黑烟流的方法相结合，最终将有可能监测热液喷口场的总热量输出。

The total heat and fluid output of diffuse hydrothermal ventingat oceanic ridge crests is unknown on the vent field scale. Likewise, its variability in time has not been measured. The investigators have formulated a hydrodynamic model of this flow to guide the measurements. The model is currenty being studied in their laboratory. This model will be used to guide the design of, and interpret the results from a sensor array to monitor diffuse hydrothermal flow. The measurements will be made using proven deep-sea instruments; the Benthic Acoustic Stress Sensor (BASS); and thermistor moorings. This sensor array will lead to a techniquefor monitoring the activity of entire diffuse hydrothermal fields over long-term developments. Coupled with methods for monitoring black smoker flow that have already been developed,it will eventually be possible to monitor the total output of heat from a hydrothermal vent field.
