Ocean Floor Depth 3d Graph

Some features like canyons and seamounts might look familiar while others such as hydrothermal vents and methane seeps are unique to the deep.

Ocean floor depth 3d graph. The speed of sound in water is 1 454 meters per second. The sea floor depth or bathymetry is computed by measuring the time it takes for the sound to leave the sonar hit the sea floor and return to the sonar. The table below gives you some more sonar sounding data. These sonar systems collect two types of 3d data.

While the ocean has an average depth of 2 3 miles the shape and depth of the seafloor is complex. The formula to find the ocean floor depth is d t v. And to graph a simple figure that com municates the concept of ocean depth. Write the formula for measuring ocean depth on the board.

This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. In the formula d stands for depth t for time between sending and receiving and v for the speed of sound in water. The video below explains the gravitational mapping technique in more detail and shows a tour of the ocean floor. Sea floor depth and backscatter.
