ABSTRACT
Bathymetry is the science of measuring the depths of the oceans, seas, etc. and charting the shape and topography of the ocean floor. The name comes from Greek terms bathus meaning deep, and metron meaning measure. Hence bathymetry can be understood as the measurement of depth of deep sea or hydrographic body. In other words bathymetry is the study of underwater depth of lake or ocean beds. Bathymetric measurements can determine the topography of the ocean floor. Using bathymetric data one can study the sea floor, which is varied, complex, and ever-changing, containing plains, canyons, active and extinct volcanoes, mountain ranges, and hot springs. Some features, such as mid-ocean ridges where oceanic crust is constantly produced and subduction zones, also called deep-sea trenches, where it is constantly destroyed, are analyzed using the bathymetric data.
