Sonar is used to map the seafloor.

While Wegner's theory of continental drift assumed that continents plowed through and over oceanic crust, his basic ideas are still upheld today. As a result of submarines and radar technology used in WWII, scientists were better able to map the seafloor. In doing so they discovered the seafloor's topography, age, magnetism, and the Mid-Atlantic Ridge. After discovering that the seafloor did spread apart and that continents moved, Wegner's theory gradually became accepted.
A geological process created topography, Topography is the shape or configuration of the land, represented on a map by contour lines, hypsometric tints, and relief shading.

An isochron is a line on a map that connects points that have the same age. An isochron map of the ocean floor supports the theory of seafloor spreading because it shows the older rock near the deep sea trenches and the younger rocks near ocean ridges.
In a nutshell sea floor topography is the study or mapping of geologic features at the bottom of the sea.
