Bell Buoy Adrift

This lost lonesome buoy drifts out into the deep dark open waters of the great sea. Its bell, once a warning call for ships approaching shore, is now a shout for help, crying out to anyone for a tug back to shore. But the wet wasteland expands as far as the bell can squeak, not an ear to hear this little buoy's bellows. All alone, all alone, and falling further from shore with every passing moment. There are many kinds of buoys. A Waverider buoy is used to measure the movement of the water surface as a wave train. The wave train is analysed to determine statistics like the significant wave height and period, and wave direction. Marker buoys are used in naval warfare, particularly anti-submarine warfare, are light-emitting or smoke-emitting, or both. The marker uses some kind of pyrotechnic to provide the flare and smoke. It is commonly a 3-inch (76 mm) diameter device about 20 inches (500 mm) long that is set off by contact with seawater and floats on the surface.
