Unmanned aerial vehicles and bathyscaphes will soon start helping polar explorers in their mission on monitoring ice situation in the Arctic.
      
      Prototypes of the drones were displayed in St. Petersburg. Drone flight range reaches 900 kilometers, and speed is about 130 kmph. Cameras, installed on drones, will monitor ice fields and help forecasting ice situation.
      
      Engineers also displayed prototypes of deep-operating vehicles, able to work as deep as 6000 meters. The vehicle hosts two crewmembers, who observe underwater environment, perform photo- and video shooting, and operate mechanical manipulator.
