What machines are used in the process of mapping the ocean floor? Where is the ocean floor mapped from? Is mapping the ocean floor dangerous? Do civil engineers have anything to do with mapping the ocean floor? Thank You!
Answer 1:

Civil engineers do not have anything to do with mapping the ocean floor.

The ocean floor is mapped originally with depth-measuring cables, then with sonar, and now most recently with gravity data. As technology improves, the machines that do the mapping change, as are the places to map from. Both the cables and the sonar need to be mapped from a ship, but the gravity data can be collected by aircraft or even satellites.
