The establishment of plate tectonics marked the revolution of earth sciences in 1960s. Marine geophysics and marine geophysicists made great contribution to the revolution. During the Second World War, the development of marine technology was prioritized by both sides of the war. After it up to 1960s, extensive geophysical surveys had been carried out at seas, and a great amount of data acquired with many new discoveries. The discoveries brought about a big change of scientific philosophy and paved the way for the theory of plate tectonics.
