已经构建了一个可以监测和采样海底边界层悬浮沉积物分布的仪器系统。它由放置在海床一米以内的微型浊度计和悬浮沉积物取样器组成。该系统能够在海床以上14至100厘米的8个高度连续监测悬浮沉积物剖面，并在4个高度收集悬浮沉积物样本悬浮沉积物系统的设计是安装在装有仪器的三脚架GEOPROBE上，该三脚架含有四个电磁流速计，压力传感器，底部立体摄像机，两个温度传感器，透射计，和一个萨伏纽斯转子电流计。传感器操作、数据记录和沉积物取样事件是同步的。因此，近底流条件的详细测量与悬浮泥沙测量同时进行。该组合系统已被用于在弗朗西斯科湾，加州州和普吉特湾，华盛顿州的沉积物运输环境。
An instrument system has been constructed that can monitor and sample suspended sediment distributions in the benthic boundary layer. It consists of miniature nephelometers and suspended sediment samplers placed within one meter of the seabed. The system is capable of continuously monitoring suspended sediment profiles at eight levels between 14 and 100 cm above the seabed and collecting suspended sediment samples at four levels (20, 50, 70 and 100 cm) at three times during a deployment period.The suspended sediment system is designed to fit onto the instrumented tripod GEOPROBE which contains four electromagnetic current meters, pressure sensor, bottom stereo camera, two temperature sensors, transmissometer, and a Savonius rotor current meter. Sensor operation, data recording, and sediment sampling events are synchronized. Thus detailed measurements of the near-bottom flow conditions are made concurrently with suspended sediment measurements. The combined system has been used in sediment transporting environments within San Francisco Bay, California, and Puget Sound, Washington.
