inventions in marine technology

Marine technology has advanced greatly to improve navigation, safety, and efficiency. Key inventions include the sonar system, which uses sound waves to detect objects underwater; GPS, allowing precise positioning at sea; and modern submarines, capable of deep underwater exploration. The development of deep-sea submersibles enables scientists to explore ocean depths. Innovative hull designs and materials improve fuel efficiency and stability for ships. Additionally, renewable energy devices like wave and tidal turbines harness ocean movements for power. These inventions help us explore, utilize, and protect the oceans more effectively.
