This is achieved by explicitly taking into account the sss operation as follows.

Using sonar to map the ocean floor. By the 1920s the coast and geodetic survey an ancestor of the national oceanic and atmospheric administration s national ocean service was using sonar to map deep water. Mapping the ocean floor with echo sounding echo sounding is the key method scientists use to map the seafloor today. Second the data is projected to the sea floor. Sonar short for sound navigation and ranging is helpful for exploring and mapping the ocean because sound waves travel farther in the water than do radar and light waves.

Sonar single beam. Sonar is a type of electronic depth sounding equiptment made in the 1920 s it is an acronym for sound navigation and ranging. There are three tools used to map the ocean floor sonar satellites and submersibles. Despite this long history of mapping the seafloor only about 10 to 15 of the ocean has yet been mapped in high resolution.

The technique first used by german scientists in the early 20th century uses sound waves bounced off the ocean bottom. Tools used to map the ocean floor today s technology lets scientists to study the ocean in a quicker and precise way. First the raw sensor data is corrected by means of a physics based sss model. The first modern breakthrough in sea floor mapping came with the use of underwater sound projectors called sonar which was first used in world war i.
