Bathymetry
• Study of the ocean floor and its contours• Originally done by lowering a line over ship
with a heavy weight• Echo Sounder used a powerful sound pulse
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.
