    • A waterfowl decoy motion system comprises a self-propelled floating decoy tethered to a submerged line supported below the surface of a body of water by stakes driven into the water bottom. A thruster is attached to the bottom of the decoy such that the direction of propulsion is offset from a longitudinal axis extending along the length of the decoy by an angle of at least one degree. The tether is slidably attached to the submerged line, and a swivel located on the tether allows the decoy to rotate freely. The decoy is guided by the line as it moves across the surface of the water. When the tether reaches a stopper near each end of the line, the offset propulsion angle causes the decoy to turn in an arcing path, turn around, and travel in the opposite direction. The decoy repeats this process in a continuous loop.
    • 水禽诱饵运动系统包括一个自推进的漂浮诱饵,系在一个浸入水底的水下的水下的水面下方的支撑在水底部的桩脚。 推进器附接到诱饵的底部,使得推进方向从沿着诱饵长度延伸的纵轴偏移至少一度的角度。 系绳可滑动地附接到浸没线,并且位于系绳上的旋转件允许诱饵自由旋转。 诱饵在水面上移动时被线引导。 当系绳到达线的每一端附近的止动器时,偏移推进角度使得诱饵在电弧路径中转动,转向并沿相反方向行进。 诱饵在连续循环中重复此过程。

    • A system includes a plurality of chamber holders having openings therein, and an exposure chamber positioned in each chamber holder. Each exposure chamber includes a mesh portion and a top end cap. One exposure chamber contains a mesh bottom and one contains a closed bottom. Each chamber holder is positioned within an opening contained within a base portion. One exposure chamber may extend beyond the lower boundary of the base portion. A top portion may be secured to the base portion to contain the chamber holders. A pump, with connected supply hose, may be coupled to the top portion. The supply hose is routed through the chamber holders such that a supply hose opening is adjacent to each chamber holder. The system may include a water quality sensor and a passive sampling device coupled to the base portion. A deployment system may be connected to the top portion.
    • 系统包括其中具有开口的多个室保持器和位于每个室保持器中的曝光室。 每个曝光室包括网状部分和顶端盖。 一个曝光室包含一个网眼底部,一个包含一个封闭的底部。 每个室保持器定位在包含在基部内的开口内。 一个曝光室可以延伸超过基部的下边界。 顶部可以固定到基部以容纳室保持器。 具有连接的供应软管的泵可以联接到顶部。 供应软管被引导通过腔室保持器,使得供应软管开口邻近每个室保持器。 该系统可以包括耦合到基部的水质传感器和无源采样装置。 部署系统可以连接到顶部。
