What Did Scientists Learn About the Seafloor
Technologies Used to Explore Outer Space and the Ocean Include Submersibles, Remotely Operated Vehicles (Rovs), Satellites, Rovers, Diving/Scuba Gear, Buoys...
High-resolution seafloor mapping is a critical tool for regulating underwater resource exploration, extraction, and equipment, allowing us to decide what and where is safe. Seafloor maps also ensure that ships are able to safely maneuver around natural – and human-made – structures on the ocean bottom.
How does sonar use reflection to help map the seafloor?
In a basic, single-beam sonar system, a combined transmitter and receiver, called a transducer, mounted on the bottom of a ship generates a single sound pulse. The pulse travels downward through the water, reflects off the ocean bottom, and then returns to the surface where it is detected by the transducer.
