TOW-YO
In the technique called a “tow-yo,” scientists and crews dangle a package of sensors into the ocean from a cable connected to a ship. The ship tows the cable horizontally, while a winch alternately hoists the package up and lowers it down again like a yo-yo. The goal is to traverse and detect a plume. Amid lots of ship traffic, the crew of the research vessel Endeavor circled in a 3.1-mile radius around the Deepwater Horizon site, skillfully tow-yo-ing instruments between 2,600 and 4,600 feet deep on a mile-long cable in the sea.
