He used a navy ship to sound the sea floor. He found out magma was coming out of the mantle and into the sea floor.

sea floor spreading
The theory of seafloor spreading was proposed by Harry Hess, a geologist and Navy officer, in the early 1960s. He proposed that new oceanic crust is formed at mid-ocean ridges and then spreads outward. This theory helped to explain the mechanism behind continental drift and plate tectonics.
Harry Hess proposed the idea of seafloor spreading in the early 1960s, with his initial proposal being presented in 1960. This concept revolutionized our understanding of plate tectonics and the movement of the Earth's lithosphere.
Harry Hess came up with the theory of seafloor spreading . Alfred Wegener came up with the idea of continental drift NOT sea-floor spreading.
