Many organizations utilize several different methods of environmental monitoring. The U.S. Navy, Military, NOAA, USGS, and organizations/companies involving oceanography, fishing, civil engineering, security, and mineral prospecting all currently work with remotely operated underwater vehicles (ROV's), autonomous underwater vehicles (AUV's), and other new or developing sensor and monitoring technologies.
A remotely operated underwater vehicle, or ROV, is an underwater vehicle that completely functions underwater. It is operated by a crew, either located above or below the surface. Unoccupied and highly maneuverable, a ROV is linked to a ship by either a tether or a load-carrying umbilical cable is used along with a tether management system if working in rough conditions or deep waters. This tether or cable serves as the connection between the ROV and the ship. It provides the ROV with electric power and control commands, while providing the crew with video data.
A ROV's main functions are: searching/recovering, inspection, equipment repairing, dredging, trenching, cable-laying, and surveying. Most ROVs are equipped with at least a video camera and lights. Additional equipment is commonly added to expand the vehicle’s capabilities, such as sonars, magnetometers, still cameras, manipulators or cutting arms, water samplers, and/or other instruments that measure water clarity, water temperature, water density, sound velocity, light penetration, or temperature.
