  • Apparatus and method for seabed exploration
    Patent number: 8908476
    Abstract: Provided are an apparatus and a method for seabed exploration using an unmanned remotely operated vehicle. The apparatus for seabed exploration of the present invention includes: an unmanned remotely operated vehicle connected with a ship 2 by a cable 1; a transponder of an acoustic positioning system mounted on the unmanned remotely operated vehicle; a pinger mounted on the unmanned remotely operated vehicle and outputting a signal that is received by a receiver of an echo sounder system mounted on the ship; a measuring device mounted on the unmanned remotely operated vehicle and sensing or measuring various information on the seabed where the unmanned remotely operated vehicle is positioned; and a sediment collecting device collecting sediments of the seafloor, when the unmanned remotely operated vehicle grounds on the seafloor.
