Bathymetry is the measurement of ocean depths and the charting of ocean floor topography. The varied bathymetry of the ocean floor was first determined using soundings to measure water depth. Later, the development of the echo sounder gave ocean scientists a more detailed representation of the sea floor. Today, much of our knowledge of the ocean floor has been obtained using various multibeam echo sounders or side-scan sonar instruments (to make detailed bathymetric maps of a small area of the ocean floor); satellite measurement of the ocean surface (to produce maps of the world ocean floor); and seismic reflection profiles (to examine Earth structure beneath the sea floor).
