Harry Hess published 'The History of Ocean Basins' in 1962, outlining a theory of how tectonic plates can move which was later called 'sea floor spreading'. He identified the presence of mid ocean ridges, and that ocean trenches are where ocean floor is destroyed and recycled.

In 1962, he proposed a groundbreaking hypothesis that proved vitally important in the development of plate tectonic theory. It addressed several geologic puzzles: If the oceans have existed for at least 4 billion years, why has so little sediment accumulated on the ocean floor?
1 Οκτ 2024 · In this paper, Hess, drawing on Holmes’s model of convective flow in the mantle, suggested that the oceanic ridges were the surface expressions of rising and diverging convective mantle flow, while trenches and Wadati-Benioff zones, with their associated island arcs, marked descending limbs.
20 Μαΐ 2024 · Harry Hammond Hess, a professor of geology at Princeton University, was very influential in setting the stage for the emerging plate-tectonics theory in the early 1960s. He believed in many of the observations Wegener used in defending his theory of continental drift, but he had very different views about large-scale movements of the Earth.
The seafloor spreading hypothesis was proposed by the American geophysicist Harry H. Hess in 1960. On the basis of Tharp’s efforts and other new discoveries about the deep-ocean floor, Hess postulated that molten material from Earth’s mantle continuously wells up along the crests of the mid-ocean ridges that wind for nearly 80,000 km ...

Harry Hammond Hess (May 24, 1906 – August 25, 1969) was an American geologist and a United States Navy officer in World War II who is considered one of the "founding fathers" of the unifying theory of plate tectonics.
