梅吉尔和他的同事希望能利用这种机器来研究海岸边的海洋生物，因为在这里，螺旋桨会激起较多沉积物，而且会跟水草缠绕在一起。

Megill and colleagues hope the bot can be used to study Marine life near the shore, where a propeller would kick up too much sediment or get tangled in weeds.

几个小时后拍摄的照片式真色彩图像显示出了海岸边被冲入大洋的沉积物，以及仙台附近的黑色烟流。

The photo-like true-color image acquired a few hours later shows plumes of sediment washed into the ocean along the coast and a dark plume of smoke near Sendai.

卡德纳斯教授表示，他最近的一项研究显示，99%的河流水确实会穿过河岸边或河底的沉积物。

Professor Cardenas says his recent study shows that more than 99 percent of the river's water does pass through the river's sediment which is on the shore or bottom of the river.
