• Study of the ocean floor and its contours• Originally done by lowering a line over ship

that bounced off the bottom and then detected the bounce back.

• Multibeam Systems integrate several pulses allowing for the a continuous sampling of the seafloor

• Satellite Altimetry is now used to map the seafloor.
