Bathymetry is the measurement of ocean depths and the mapping of underwater terrain. π It's like creating a topographical map, but for the ocean floor. It uses sonar and other technologies to determine the depth of the water at various points. Bathymetry is used for navigation, resource exploration, and scientific research. Think of it as underwater archaeology, but with sound waves instead of shovels. It helps us understand the hidden landscapes beneath the waves.
