GEOLOGY

Detailed explanation-1: -Sonar, short for Sound Navigation and Ranging, is helpful for exploring and mapping the ocean because sound waves travel farther in the water than do radar and light waves.

Detailed explanation-2: -sonar, (from “sound navigation ranging”), technique for detecting and determining the distance and direction of underwater objects by acoustic means. Sound waves emitted by or reflected from the object are detected by sonar apparatus and analyzed for the information they contain. sonar.

Detailed explanation-3: -This technology also relies on sound waves to detect objects. However, sonar is typically used underwater.

Detailed explanation-4: -Different types of Sonar. Sonar is divided into 3 main categories: Searchlight Sonar (PPI Sonar), Sector Scan Sonar, and Scanning Sonar.

Detailed explanation-5: -Here’s how it works. Multibeam sonar signals are sent out from the ship. With about 1500 sonar soundings sent out per second, multibeam “paints” the seafloor in a fanlike pattern. This creates a detailed “sound map” that shows ocean depth, bottom type, and topographic features.
