probably sonar
Harry Hess used sonar and another device still not found. Hey well he actually used an echo sounding device onboard the ship U.S.S Cape Johnson in which he commandered. Hess kept the echo sounding device on throughout his journey and he gained thousands of miles of echo sound maps of the ocean floor. Malkee xx

The scientist who helped to discover the process of sea floor spreading was Harry Hess, an American geologist. He proposed the theory in the early 1960s, which revolutionized our understanding of plate tectonics and the movement of Earth's crustal plates. Hess's hypothesis helped explain the geomorphology of the ocean basins and the distribution of earthquakes and volcanic activity.
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.

he proposed that mid-ocean ridges were areas where the floors of oceans had split apart

Harry Hess mapped the ocean floor to support his hypothesis of seafloor spreading, which proposed that new oceanic crust is formed at mid-ocean ridges and older crust is pushed away. His work aimed to provide evidence for the theory of plate tectonics, which revolutionized our understanding of continental drift and geological processes. By mapping the ocean floor, Hess sought to explain the distribution of geological features and the movement of tectonic plates. His research laid the groundwork for modern oceanography and geology.
sea floor spreading
Harry Hess
Harry Hess's ocean floor surveying was of major geological importance because it led to the development of the theory of plate tectonics. His discovery of seafloor spreading provided crucial evidence for the movement of Earth's lithospheric plates, revolutionizing our understanding of Earth's geology and explaining phenomena like earthquakes and volcanic activity.
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 YAY;-)

Harry Hess hypothesized that the sea floor was spreading. He explained it through the phenomena of the youngest rocks that are found only at the mid-ocean ridges. These rocks then, get progressively older when moving away from the ridge.
