Echo sounding
Explanation:
Harry Hess discovered the Mid-Atlantic spreading ridge by using echo sounding techniques.
- Hess was a professor of Geology at Princeton University.
- After the second world war, series of equipment used were deployed for scientific use.
- The echo sounding was one of such devices that was adopted in mapping the sea floor.
- It works by sending an echo to the ocean floor and determining the height to the base by their reflection.
- From his works, he observed and noticed the mid-oceanic ridge.
- This led to the formulation of the theory of sea floor spreading.
