Remotely operated vehicles, or ROVs, play an ever-expanding role in the exploration of the deep ocean environment. These relatively small submersibles are able to explore remote depths without placing humans in jeopardy. In order to locate target sites, underwater camera sleds and ROVs must often follow a well-defined search pattern. Using methodical sweeping movements, these craft will locate objects that might otherwise be overlooked if a more random searching method was employed. In this activity, you'll get to create a search pattern that will be used to uncover hidden targets.
