How do scientists map the seafloor?

Answer 1

SONAR

An echo-sounding device known as a sonar is used to measure the depth of the ocean at different locations. Initially, a sound wave is directed from a ship toward the ocean floor, and it is reflected back to the ship by the ocean floor. Since sound travels at a certain speed in water, scientists can calculate the depth of the ocean floor based on the time it takes for the sound wave to return to the ship. Computers then use the sonar data to create a map of the ocean floor.

Answer 2

Scientists map the seafloor using various techniques, including sonar technology, satellite altimetry, and gravity measurements. Sonar technology involves sending sound waves from a ship or underwater vehicle to the seafloor and measuring the time it takes for the sound waves to bounce back. This data is used to create detailed maps of the seafloor's topography. Satellite altimetry measures the height of the ocean's surface relative to the Earth's center of mass, which provides information about the underlying seafloor topography. Gravity measurements detect variations in the Earth's gravitational field caused by variations in seafloor topography, which can also be used to map the seafloor.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
